GAO Highlights: 

Highlights of GAO-10-67, a report to Subcommittee on Air and Land 
Forces, Committee on Armed Services, House of Representatives. 

Why GAO Did This Study: 

DOD used nearly 700 aircraft, as well as commercial and leased 
aircraft, to carry about 3 million troops and 800,000 tons of cargo in 
support of wartime, peacetime, and humanitarian efforts in 2008. C-5s 
and C-17s move troops and cargo internationally (strategic airlift) and 
C-130s are the primary aircraft that moves them within a theater of 
operation (tactical airlift). Over the next 4 years, DOD plans to spend 
about $12 billion to modernize and procure airlifters and is currently 
studying how many it needs. 

GAO was asked to (1) identify the status of DOD’s modernization and 
acquisition efforts and (2) determine how well DOD is addressing any 
capability gaps and redundancies. In conducting this work, GAO 
identified the cost, schedule, and performance of airlift programs, as 
well as DOD’s plan for addressing gaps and redundancies. GAO also 
discussed mobility study efforts with DOD, Institute for Defense 
Analysis (IDA), and RAND officials. 

What GAO Found: 

DOD has recently revamped airlift investments due to modernization cost 
increases and requirement changes. For strategic airlift, the number of 
C-5s that will be fully modernized were cut in half because of 
substantial reengining cost increases and C-17 quantities were 
increased from 180 to 213 aircraft. These twin changes resulted in a 
net cost increase of about $3 billion. Additional costs and force 
structure changes are possible pending decisions on C-5 retirements, 
other modifications, the potential need for more C-17s to meet tactical 
airlift needs, and the planned shutdown of C-17 production. For 
tactical airlift, substantial cost increases for modernizing C-130 
avionics tripled unit costs, delayed its schedule, and resulted in 
almost 60 percent fewer aircraft being modernized. There have been 
large increases in the C-130J quantity to replace older C-130s, but 
modest increases in unit costs. The joint Army-Air Force C-27J program 
was recently transferred to the Air Force and quantities were cut from 
78 to 38 aircraft, with an uncertain effect on the Army’s airlift 
missions. The Army and Air Force must also resolve fundamental 
differences in operating requirements and employment strategy for the 
Joint Future Theater Lift (JFTL). 

DOD appears to have addressed its strategic airlift gap, but there is a 
potential future tactical airlift gap for moving medium weight 
equipment. Also, questions regarding how the Air Force will meet the 
Army’s direct support mission have not been resolved. DOD is using $5.5 
billion appropriated by Congress to procure 23 additional C-17s, which 
DOD officials believe more than offsets the strategic airlift gap 
associated with the restructured C-5 modernization program. However, 
there is a potential gap in the tactical airlift of medium weight loads 
beyond the capability of the C-130s. The C-17 is the only aircraft 
capable of moving this type of Army equipment within a theater of 
operation, although not to austere, short, or unimproved landing areas. 
The JFTL is envisioned to provide this capability, but will not be 
available for 15 years or more under the current acquisition strategy. 
While the various mobility studies acknowledge the C-17’s significant 
dual role, they did not comprehensively evaluate the expanded use of 
the C-17 to transport medium weight equipment in theater and how this 
could impact the force structure, the C-17’s service life, and 
decisions related to when to shut down the production line. In 
addition, questions remain about the number of C-130s and C-27Js needed 
to fulfill Army direct support missions. Two studies reached somewhat 
different conclusions about the cost effectiveness of using C-130Js and 
C-27Js for this mission. The Air Force and Army have not completed a 
plan for meeting Army direct support requirements, which could affect 
future decisions on both the C-27J and the C-130J. DOD’s recently 
established portfolio management structure is supposed to provide a 
useful forum to address the broad range of airlift investment 
decisions. However, efforts so far have primarily focused on new 
programs rather than addressing gaps and making other airlift decisions 
such as when and how many C-5s to retire or the appropriate mix of C-
130s and C-27Js needed to perform Army missions. 

What GAO Recommends: 

GAO recommends, among other things, that DOD broaden the scope of its 
portfolio discussions, determine if additional C-17s are needed, and 
determine how Army direct support requirements will be met. DOD 
partially concurred with the recommendations, citing they have ongoing 
plans or processes to address the issues raised. As discussed in the 
report, GAO believes DOD needs to take additional steps to fully 
respond to the recommendations.

Ranking Member: 
Subcommittee on Air and Land Forces: 
Committee on Armed Services: 
House of Representatives: 

The Department of Defense (DOD) employs over 700 aircraft to move 
troops and cargo in support of wartime operations, peacetime missions, 
and humanitarian aid efforts. In 2008, these airlifters along with 
commercial and leased aircraft flew more than 160,000 sorties, moving 
about 800,000 tons of cargo and 3 million troops. The Air Force's C-5s 
and C-17s perform the intertheater movement of troops and cargo, 
referred to as strategic airlift, and its C-130s provide most 
intratheater transport, referred to as tactical airlift. 

The department plans to spend about $12 billion over the next 4 years 
to modernize and recapitalize its airlift fleets. This includes 
upgrading the avionics on C-5s and selected C-130 models, replacing 
engines on about half of the C-5 fleet, and acquiring additional C-17s 
and C-130Js. DOD is also procuring C-27J Joint Cargo Aircraft and has 
begun initial planning efforts on the Joint Future Theater Lift (JFTL), 
both slated for tactical airlift. Growing fiscal pressures, however, 
may cause DOD to reexamine or restructure programs that exceed cost and 
schedule targets. Because of the costs, complexities, and 
interrelationships of airlift programs and the need for greater 
insight, we examined, at your request (1) the cost, schedule, and 
performance status of modernization efforts and new airlift programs 
and (2) how well DOD is managing the airlift portfolio to make 
investment decisions that address any capability gaps and redundancies. 
This report builds and expands upon information reported to you on 
strategic airlift issues in November 2008[Footnote 1] and provides new 
information on tactical airlift programs and issues. 

In conducting our work, we interviewed and obtained documentation from 
officials within the Office of the Secretary of Defense and U.S. 
Transportation Command related to the ongoing Mobility Capabilities and 
Requirements Study 2016 and portfolio management activities. DOD 
officials did not provide a copy of or detailed information about the 
study results because the analysis had not been completed. Instead, 
officials provided status updates and answered questions about 
potential gaps and redundancies. We met with officials from each of the 
weapon system program offices[Footnote 2] to obtain current cost, 
schedule, and performance information. When appropriate, we discussed 
reasons for variances from cost, schedule, and performance targets and 
upcoming acquisition, modernization, or retirement decisions related to 
their particular program. In addition, we met with Institute for 
Defense Analysis (IDA) and RAND Corporation (RAND) officials to discuss 
the results of their DOD-sponsored mobility studies. We also relied on 
our previous reports related to portfolio management, DOD mobility 
studies, and various weapon systems for information. A list of these 
reports is included in the Related GAO Products section at the end of 
this report. We conducted this performance audit from January 2009 to 
November 2009 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Background: 

DOD uses a variety of aircraft to move weapons, equipment, and troops 
from the United States to and within theaters of operation. C-5s and C- 
17s are used for strategic airlift. They carry weapons and equipment 
too large for any other DOD aircraft from the United States to staging 
locations throughout the world. The family of C-130 aircraft, which 
includes the C-130E, C-130H, and C-130J aircraft, is then the primary 
asset used to move weapons, equipment, and troops within a theater of 
operation.[Footnote 3] The C-17 is dually capable of performing both 
strategic and tactical airlift missions and supplements the C-130 for 
tactical airlift. All of these aircraft are owned and operated by the 
Air Force and are considered part of the common user pool of aircraft 
that can be used to support any of the services' missions. DOD also 
relies on the Air Force's aerial refueling tankers (KC-10 and KC-135), 
commercial aircraft, and leased aircraft to supplement airlift 
capabilities. Officials at the U.S. Transportation Command and its Air 
Force component, the Air Mobility Command, decide on how best to use 
the assets on a daily basis. Often, these aircraft are scheduled for 
departure when they have a full load, to ensure assets are used cost- 
effectively. The services may also use their own airplanes and 
helicopters that are not in the common user pool to move people and 
cargo within a theater of operation. For example, these assets include 
the Army's C-23 Sherpas and the Marine Corps' V-22 Osprey aircraft. 
These aircraft are used to perform time-sensitive, mission-critical 
requirements and may take off without full loads since urgency is the 
primary driver for the mission, not efficiency or cost-effectiveness. 

The Air Force is in the process of modernizing its C-5 and C-130H 
aircraft and acquiring C-17s, C-130Js, and C-27Js to meet its future 
strategic and tactical airlift requirements and improve aircraft 
availability. It plans to retire C-130Es from the tactical airlift 
fleet by 2014. C-5s are being modernized in two phases. During the 
first phase, known as the Avionics Modernization Program (AMP), 
aircraft receive upgraded avionics capabilities and an all-weather 
flight control system. During the second phase, known as the 
Reliability Enhancement and Reengining Program (RERP), aircraft engines 
are replaced and electrical, fuel, and other subsystems are modified. 
Together, the two modifications will help improve the C-5s wartime 
mission capable rate. C-130H aircraft are also receiving an AMP 
modification and will undergo a center wing box replacement because of 
severe cracking discovered in that area. 

DOD periodically assesses global threats, the national military 
strategy, and its force structure to determine future airlift 
requirements and to judge the sufficiency of its acquisition and 
modernization plans. The analytical basis for DOD's current airlift 
requirements is the Mobility Capabilities Study completed in December 
2005.[Footnote 4] Officials used the study results to report in the 
2006 Quadrennial Defense Review that 180 C-17s and 112 fully modernized 
C-5s (those that received the AMP and RERP modifications) would be 
sufficient to meet the national military strategy for strategic airlift 
with acceptable risk. This could change pending the completion of the 
ongoing DOD Mobility Capabilities and Requirements Study 2016, two 
other DOD-sponsored airlift studies conducted by IDA and RAND, the 2010 
Quadrennial Defense Review, and potential changes in threat assumptions 
and the national security strategy. The IDA study has already been 
completed and the remaining studies are expected to be completed by 
January 2010. 

Airlift Acquisition and Modernization Programs Have Been Restructured 
to Address Rising Costs and Changes in Airlift Needs: 

Over the last 2 years, DOD has restructured its airlift investments, 
primarily due to sharp cost increases for modernization programs and 
changes in requirements. The Air Force now intends to fully modernize 
less than one-half of the C-5s it originally planned and will procure 
additional C-17s. C-130 avionics modernization quantities were also cut 
more than half and the schedule was delayed due to cost increases. The 
Air Force is procuring more C-130J models than planned, due in part to 
a decision to retire the older C-130E model. Pending decisions on 
aircraft retirements, additional modifications, and new acquisitions 
could further affect future costs and the force structure. Furthermore, 
changing needs and uncertain strategies could lead to cost, schedule 
and performance variances on two new airlift programs, the C-27J and 
the JFTL. Appendix 1 contains more in-depth cost, schedule, and 
performance information on the department's strategic and tactical 
airlifters that we reviewed. 

Strategic Airlift: DOD Is Modernizing Fewer C-5s, but Acquiring More C- 
17s: 

DOD has cut its C-5 modernization efforts by more than half and is 
acquiring additional C-17s. Significant cost increases on the C-5 RERP 
and AMP programs drove up unit costs and delayed schedules. These 
problems, along with additional congressional appropriations that DOD 
is using to procure more C-17s, led to a decision to fully modernize 
only 52 C-5 aircraft instead of the entire fleet. Congress has provided 
enough funding for DOD to procure 33 more C-17s. The last one will be 
delivered in March 2011. 

Substantial C-17 production line shutdown costs--ranging from about 
$465 million to about $1 billion by Air Force and Boeing estimates, 
respectively--have yet to be determined, but will need to be funded 
soon. Table 1 summarizes changes in cost and quantities from original 
estimates.

[End of table] 

DOD has nearly completed its C-17 acquisition program and is about 
midway through the C-5 AMP modernization program. According to program 
officials, 24 C-17s are yet to be delivered and 57 C-5s still need the 
AMP modification. The C-5 RERP modernization program is just beginning 
the low rate initial production phase. Only 3 of 52 C-5s have received 
the RERP modification as part of the development program. DOD has 
already spent about $69.2 billion on research, development, test and 
evaluation (RDT&E) and procurement funds on these programs and program 
officials project they will need to invest about $7.7 billion to 
complete the programs as currently planned (see table 2).

[End of table] 

The department planned to spend about $12 billion to make AMP and RERP 
modifications to the fleet of C-5 aircraft by 2020. However, the Air 
Force declared a Nunn-McCurdy cost breach[Footnote 5] in the RERP 
program in September 2007, due to increased labor and parts costs. The 
AMP effort required additional software development to address 
deficiencies found during developmental testing. Development costs 
would have been higher except that the Air Force decided not to address 
250 deficiencies and 14 operational requirements in this program. These 
events resulted in revised plans to provide the AMP upgrade to all C-5 
aircraft and the RERP modification to 52 aircraft. The combined cost 
for both modifications was reduced to $9.1 billion, but now less than 
one-half of the fleet will be fully modernized and at a much higher 
unit cost than originally estimated--$160.5 million for both 
modifications versus $96.1 million. The portion of the fleet that does 
not get both modifications will continue to experience mission capable 
rates of around 50 percent compared to about 75 percent for the portion 
that does get both modifications. The last modifications are supposed 
to be finished in 2015. 

Additional costs and changes in the force structure for the C-5 and C- 
17 are possible pending decisions on future modifications and 
retirements of older C-5s. For example, program officials said that 
many of the deficiencies and requirements dropped from the current C-5 
AMP effort will be addressed in annual AMP software upgrades, the C-5 
RERP, or a new block upgrade program that is scheduled to begin in 
fiscal year 2010. The C-17 is also addressing modernization through a 
series of aircraft upgrades designed to address emerging issues such as 
international airspace access requirements and critical operational/ 
safety issues. 

Significant C-5 cost growth and further delays are possible if the RERP 
program is not adequately funded. We previously reported that, 
according to the department's Cost Analysis Improvement Group, the RERP 
program was underfunded by about $294 million, with additional funding 
needed in fiscal years 2012 and 2013.[Footnote 6] Replacement engines 
are the costliest portion of the RERP upgrade, and DOD officials said 
if funding is insufficient to meet yearly production quantities in 
existing purchase agreements, anticipated price breaks will not occur 
and could likely result in another Nunn-McCurdy unit cost breach and 
program restructure. Department officials said the Air Force is 
committed to fully funding the RERP modification of 52 aircraft, but 
did not provide us with new budget data for fiscal years 2011 and 
beyond. 

Planned quantities of C-17s have fluctuated over the years. C-17 
procurement began in 1988 and the Air Force initially planned to 
acquire 210 aircraft. Following a major acquisition review in 1990, the 
program was reduced to 120 aircraft because of technical problems and 
funding shortfalls during the full-scale development program, which 
resulted in higher than expected cost increases and schedule delays. 
[Footnote 7] In subsequent years, DOD expanded the program from 120 
aircraft to 180 aircraft and, in the past 3 fiscal years, Congress has 
provided funding that would allow DOD to procure 33 additional 
aircraft: 10 in fiscal year 2007,[Footnote 8] 15 in fiscal year 2008, 
[Footnote 9] and 8 in fiscal year 2009.[Footnote 10] This would bring 
the total number of C-17s DOD plans to procure to 213. As of July 2009, 
DOD had taken delivery of 190 aircraft. The program is expected to end 
with the delivery of the 213th aircraft in March 2011, at which time 
the production line could be shut down if Boeing does not receive 
additional international orders for the aircraft. The Air Force's 
fiscal year 2010 budget includes $91.4 million to fund some of the 
shutdown costs and a DOD official stated that additional funding would 
be included in future budgets. However, final shutdown costs have not 
been negotiated between the Air Force and Boeing, the prime contractor. 
Last year we reported that the Air Force estimated the costs to be 
around $465 million and Boeing's estimate was about $1 billion. 
[Footnote 11] 

Tactical Airlift: C-130 AMP Modernization Program Has Been Cut and 
Uncertainty Surrounds New Programs: 

DOD's tactical airlift investments have also experienced cost and 
schedule fluctuations and continue to experience significant 
uncertainty. The AMP program to modernize the C-130H fleet has been 
substantially reduced, although officials are examining a possible 
follow-on effort to include more aircraft. Procurement quantities for 
the C-130J have increased to replace retiring C-130E models and plans, 
quantities, and employment strategies for the newest tactical aircraft, 
the C-27J, have yet to be finalized following a decision to transfer 
the joint program entirely to the Air Force. Table 3 summarizes changes 
in cost and quantity for current tactical aircraft. The JFTL, expected 
to augment the C-130 fleets, is in concept development and cost and 
quantity estimates are unavailable.

DOD has not yet begun its C-130 AMP production program and has only 
taken delivery of 2 C-27Js as of July 2009. The department has more 
than half of its C-130J acquisitions--95 aircraft--yet to procure. DOD 
has already spent $10.1 billion in RDT&E and procurement funds on these 
programs. Program officials project it will cost about $12.6 billion to 
complete the programs as currently planned (see table 4).

The C-130 AMP entered system development in 2001, but funding 
instability and problems integrating hardware and software, as well as 
an Air Force decision to exclude C-130E aircraft from the program, 
triggered a Nunn-McCurdy unit cost breach in February 2007. The program 
was subsequently restructured to include far fewer aircraft--221 
instead of 519--at a cost $1.8 billion greater than the original 
program estimate. In spite of the restructuring, incomplete production 
decision documentation and software integration problems, as well as 
senior leadership concerns about the acquisition strategy, have delayed 
a low-rate production decision by more than a year from the revised 
baseline--a slip of more than 4 years from the initial estimate. As of 
July 2009, the program was still awaiting approval from the Under 
Secretary for Acquisition, Technology and Logistics to award a 
production contract. The Air Force is considering another program 
restructure as well as a follow-on effort to modernize avionics on 
additional C-130 aircraft, but officials did not provide us an estimate 
of costs and quantities. 

The department is now procuring more C-130J aircraft than originally 
expected, in part because of a decision to retire C-130Es. Production 
quantities for J-model aircraft have grown significantly over the last 
several years, from an initial baseline of 11 aircraft in 1996 to a 
current estimate of 168 aircraft, but according to program estimates, 
program unit costs have remained relatively stable. Program officials 
estimate a total program cost of $15 billion. As of July 2009, 73 C- 
130Js have been delivered. 

Recently, the department took delivery of the first two C-27J 
airlifters as part of the Joint Cargo Aircraft program to provide 
direct support for Army time-sensitive, mission-critical troop 
resupply. In June of 2007, the Under Secretary for Acquisition, 
Technology and Logistics approved an acquisition program baseline for 
the joint program of 78 aircraft, with the Army planning to buy 54 
aircraft, and the Air Force 24. However, as part of its fiscal year 
2010 budget request, the department transferred the program, along with 
the resupply mission it supports, exclusively to the Air Force and 
reduced the program from 78 to 38 aircraft. Air Force operational plans 
for the fleet and employment concepts for meeting Army direct support 
requirements have not been finalized. 

The Army and the Air Force are jointly pursuing the JFTL to replace the 
C-130H airlifter and augment the rest of the C-130 fleet. The joint 
concept development effort was initiated in January 2008 following a 
decision by the Army and Air Force Chiefs of Staff to merge 
requirements for separate heavy lift efforts in progress at the time. 
The JFTL is anticipated to have a payload capacity of up to 36 tons, 
with a combat mission radius of 500 nautical miles. However, the 
services have different concepts for the aircraft. The Army concept is 
for a vertical take-off and landing tiltrotor that could provide 
sustainment of forces at the point of need and enable the maneuver of a 
mounted force (i.e., forces deployed with combat vehicles) by air. The 
Air Force is pursuing a fixed wing concept that would address the need 
to operate on short, soft, or rough airfields and the need for greater 
speed. Officials from both services stated they would like to have the 
JFTL initial capabilities document validated and begin work on an 
analysis of alternatives[Footnote 12] in the late summer of 2009, to 
help ensure a sufficient basis for budget deliberations in March 2010. 
As of July 2009, this had not occurred. Documents provided by these 
officials indicate that system development for whichever concept is 
selected is not expected to begin until at least 2014, with the new 
system to be fielded beginning around 2024. 

Strategic Airlift Gap Has Been Addressed, but a Potential Tactical 
Airlift Gap for Moving Medium Weight Equipment and Other Questions Have 
Not Been Resolved: 

Additional funds provided by Congress for C-17 procurement more than 
offset the strategic airlift gaps associated with reduced C-5 
modernization plans. However, there is a potential future gap in 
tactical airlift capabilities for transporting medium weight Army 
equipment that cannot fit on C-130 aircraft. The C-17 fleet, in its 
dual role of providing both strategic and tactical airlift, currently 
provides this capability and is anticipated to continue to do so for 
many years. The JFTL is envisioned to eventually replace the C-130H and 
perform this and other roles, but will not be available for 15 years or 
more under the current acquisition strategy. While the various mobility 
studies acknowledge the C-17s' significant dual role, they did not 
comprehensively evaluate an expanded future use of the C-17 for the 
transport of medium weight equipment and how this could affect the 
force structure, the C-17s' service life, and when to shut down the C- 
17 production line. For example, the studies do not quantify current 
and anticipated future use of the C-17 for tactical airlift. This is 
because DOD officials do not consider the C-17 to be a suitable 
substitute for the JFTL. In addition, there are differing opinions 
about the transport of small loads in direct support of Army units, 
which could call into question the quantity of C-27Js needed to perform 
the Army mission. Two studies reached somewhat different conclusions 
about the cost effectiveness of using C-130Js and C-27Js for this 
mission. The Air Force and Army are working on a plan for how the Air 
Force will meet Army direct support requirements, but the details have 
not been finalized. DOD's recently established portfolio management 
structure is supposed to provide a useful forum to address the broad 
range of airlift investment decisions. However, efforts so far have 
been primarily focused on new programs rather than addressing gaps and 
redundancies across the current portfolio, as well as making other 
airlift decisions, such as when and how many C-5s to retire or the 
appropriate mix of C-130s and C-27Js needed to perform Army missions. 

Acquisition of Additional C-17s Addresses Strategic Airlift Gap: 

Following DOD's decision to reduce the number of C-5s that will be 
fully modernized from 111 to 52 aircraft, Congress has appropriated 
around $5.5 billion that DOD plans to use to procure up to 23 
additional C-17s. This would bring the total number of C-17s the Air 
Force now plans to acquire to 213 aircraft. DOD and Air Force officials 
believe this current quantity of C-17s more than adequately addresses 
their strategic airlift requirements in terms of the number of aircraft 
needed and the collective delivery capabilities. Table 5 shows the 
changes in the strategic airlift mix since the time the 2005 Mobility 
Capabilities Study was completed and the impact the different mixes 
have had on DOD's ability to meet strategic airlift requirements for 
the timely inter-theater transport of required equipment and supplies.

Note: The million ton-mile measure is a common metric included in prior

fleet of strategic airlifters. 

[End of table] 

A recent IDA study concluded that 316 strategic airlifters, which 
include 205 C-17s, 52 fully modernized C-5s, and 59 partially 
modernized C-5s, meets DOD's strategic airlift requirements established 
in the 2005 Mobility Capability Study.[Footnote 13] Further, if 
additional airlift capacity is needed above what the current mix of 
aircraft can deliver, it could be achieved without procuring additional 
C-17s or modernizing C-5s. Specifically, IDA found that additional 
capacity could be obtained by: 

* using C-5s at Emergency Wartime Planning levels: 

* transporting some small oversize as well as bulk cargo using Civil 
Reserve Air Fleet aircraft: 

* making use of host nation airlifters to the maximum extent possible 
and: 

* using tankers not involved in tanker missions to carry cargo in 
theater. 

In the event that even more capacity is needed, the IDA study states 
that it would be more cost-effective to provide the RERP modification 
to more C-5s than to procure additional C-17s because the near-term 
acquisition costs are offset by reduced operation and support costs. 
IDA also concluded that retiring older C-5As to free up funds to buy 
and operate more C-17s would result in a less capable force at 
comparable overall cost and thus would not be cost-effective. 

Potential Tactical Airlift Gap Exists in Movement of Medium Weight 
Equipment on the Battlefield: 

A potential future capability gap exists in the deployment and 
redeployment of Army medium weight weapon systems within a theater of 
combat. The C-17 is the only aircraft currently capable of transporting 
heavier equipment, such as combat configured armored Strykers and Mine 
Resistant Ambush Protected vehicles, within a theater of operations as 
these are too large and bulky for C-130s to carry. However, the C-17 
cannot transport this equipment into austere, short, or unimproved 
landing areas. DOD's long-term plan is to use the JFTL, the planned C- 
130H replacement, to transport these vehicles in theater, including to 
such access-challenged locations. However, it will not be available for 
at least 15 years as currently planned. While the various mobility 
studies acknowledge the C-17 can perform both strategic and tactical 
airlift missions, none of the three recently completed or ongoing 
studies comprehensively considered the C-17 in the tactical force 
structure, even though about 20 percent of the tactical sorties flown 
by the C-17 fleet in fiscal year 2007 were for missions where loads 
were too large for C-130s. As such, DOD has not evaluated the impact 
the increasing tactical heavy lift mission will have on future tactical 
airlift requirements, the C-17's service life, its availability to 
perform strategic airlift and other tactical airlift missions, and the 
impact it could have on C-17 production shutdown plans. 

DOD officials do not believe that the C-17 is a suitable substitute for 
the JFTL mission. A DOD official stated that preliminary results of the 
Mobility Capabilities and Requirements Study 2016 show that in the 
worst case planning scenario there would be enough C-17s to perform its 
primary role as a strategic airlifter, as well as some tactical 
missions through 2016. This is because the study analysis shows the 
peak demand for the C-17 and the C-130 occurs at different times and 
the C-17 is aging as planned. However, officials indicated that none of 
the current mobility studies analyzed the need for the C-17 to perform 
additional tactical heavy lift missions for the 8-year period between 
2016 and 2024, when the JFTL is expected to be fielded. Furthermore, 
because we were not granted access to the preliminary study 
information, we could not ascertain the extent to which the C-17's 
heavy lift mission had been considered in DOD's analysis through 2016. 
C-17 production is scheduled to end in March 2011. As we previously 
reported a well-reasoned, near-term decision on the final C-17 fleet 
size could help DOD avoid substantial future costs from ending 
production prematurely and later restarting production.[Footnote 14] 
For example, the Air Force has estimated that restoring the production 
line could cost $2 billion. Costs and challenges associated with such a 
course include hiring and training a workforce of nearly 3,100 people, 
reinstalling and restoring production tooling, and identifying 
suppliers and qualifying their parts and processes. 

Although it is too early to comment on JFTL program outcomes, we 
believe DOD officials will need to exercise caution to avoid pitfalls 
we have previously identified in connection with developing new weapon 
systems so the new system will be delivered on time and within cost 
estimates.[Footnote 15] These pitfalls include taking a revolutionary 
versus an evolutionary approach for weapon system development, over 
promising performance capabilities; increasing requirements; and 
understating expected costs, schedules, and risks associated with 
developing and producing the weapon. DOD understands many of the 
problems that affect acquisition programs and has revised its 
acquisition policy as a foundation for establishing sound, knowledge- 
based business cases for individual acquisition programs.[Footnote 16] 
For example, the policy recommends the completion of key systems 
engineering activities before the start of development, including a 
requirement for early prototyping, and establishes review boards to 
evaluate the effect of potential requirements changes on ongoing 
programs. The policy also supports evolutionary acquisitions and states 
that increments should be fully funded, include mature technologies, 
and normally be developed in less than 5 years. However, to improve 
outcomes, DOD must ensure that its policy changes are consistently 
implemented and reflected in decisions on individual programs. 

Both Air Force and Army science and technology officials indicated that 
no new technology invention is needed for either of their concepts. 
However, tiltrotor technology has never been applied to a system of the 
size needed to carry all the Army's ground vehicles (excluding the M-1 
tank). In fact, the Army envisions the JFTL's payload capacity will be 
nearly 5 times that of the V-22, the world's first production tiltrotor 
aircraft and nearly 3 times that of the CH-47 Chinook, a heavy lift 
helicopter used to transport ground forces, supplies, and other 
critical cargo. In addition, the Senate Armed Services Committee 
recently noted that to support the JFTL initial operational capability, 
a prototype would need to be flying by 2015.[Footnote 17] Yet, the 
committee could not identify any DOD funds budgeted for accomplishing 
this objective, and further observed that waiting to conduct a 
competitive prototyping effort as part of an acquisition program would 
take years to begin. As such, the committee requested the Under 
Secretary for Acquisition, Technology and Logistics to, among other 
things, assess the merits of initiating a low-cost, highly streamlined 
competitive prototyping effort immediately, determine whether cost and 
performance goals can be met, help define requirements, and sustain the 
industrial base. 

Mix of C-130s and C-27Js Needed to Support Army Missions Has Not Been 
Determined: 

Questions remain about the number of C-130s and C-27Js needed to 
support Army direct support missions. As stated earlier, as part of its 
fiscal year 2010 budget request, the department transferred the C-27J 
program, along with the resupply mission it supports, exclusively to 
the Air Force and reduced the program from 78 to 38 aircraft. In a 
recent hearing, congressional leaders questioned the Secretary of 
Defense about how the Air Force will fulfill this mission with fewer 
aircraft than initially anticipated.[Footnote 18] In response, the 
Secretary of Defense stated that the reduced number of C-27Js was based 
on the number needed to recapitalize the Army's fleet of C-23 Sherpas 
and that uncommitted C-130 aircraft can be used to complement the C- 
27Js to fulfill the Army's mission. In addition, he said there needs to 
be a change in the Air Force's culture with respect to how the direct 
support mission is accomplished. 

The Air Force and Army are in the process of developing plans on how 
the Air Force intends to fulfill the direct support mission, which 
would include important decisions on employment concepts, basing, and 
life-cycle support. The plans are in various stages of development and 
are expected to be completed by October 2012. However, congressional 
concerns remain regarding the service's commitment to that mission. 
This concern is based on historical instances in which the Air Force 
assigned lesser priority to direct delivery missions compared with 
traditional airlift operations, most notably during the Vietnam War 
when the Air Force assumed ownership of the Army's C-7 Caribou aircraft 
and subsequently dropped some missions. It is also unclear what effect 
this program change will have on the Air Force's C-130 fleet 
operations. 

In recent studies, IDA and RAND assessed the use and roles of the C- 
130s and C-27Js in performing tactical missions. Although the study 
parameters were different, they both looked at the tactical movement of 
cargo. IDA's analysis focused on the use of these aircraft within the 
context of major combat operations as well as persistent global 
involvement in numerous smaller operations. IDA found that the tactical 
fleets they examined were equally cost-effective at transporting cargo 
in major combat operations. Whereas C-130s are more cost effective than 
the C-27Js in specific missions that demand full loads, the opposite is 
true when missions require small loads. Further, in non-major combat 
operations, IDA found that the global demand for small loads on numbers 
of aircraft in different locations made additional C-27Js more cost- 
effective than additional C-130s. 

According to RAND officials, RAND work on this topic has been underway 
for several years. The first RAND study focused on determining the most 
cost-effective way to recapitalize the C-130 fleet in order to meet the 
official wartime requirement. This study concluded that acquisition of 
the extended version of the C-130J was the most cost effective option 
to perform tactical missions defined in the officially approved wartime 
requirement. The C-27J provides about 40 percent of the cargo capacity 
(in terms of pallets) as the extended C-130J at about two-thirds the 
cost, based on net present value total life cycle costs. In addition, 
the study also concluded that the extended C-130J and the C-27J were 
equally cost-effective at conducting the ongoing resupply missions in 
Iraq and Afghanistan. RAND was then asked to consider the cost- 
effectiveness of the C-27J in eight additional missions that were not 
part of the official requirement. The study concluded that the C-27J 
was not cost-effective or appropriate for five of those missions and 
was comparable to the C-130J in three of the missions. RAND also found 
that the C-130J and the C-27J have comparable performance under 
operationally consistent circumstances of delivering the same amount of 
cargo at the same distances. 

It should be noted that neither of these studies addressed recent C-27J 
program decisions that resulted in the transfer of the program to the 
Air Force and a reduction in aircraft quantities. Likewise, neither of 
the studies considered the number of C-130s that may be necessary to 
supplement these missions or the impact the missions may have on the C- 
130 fleet. Furthermore, because the C-27J was not initially considered 
part of the common user pool, the ongoing DOD Mobility Capabilities and 
Requirements Study 2016 did not include the C-27J in the common user 
pool in its analysis. Following the restructuring, an Air Force 
official told us that, while the C-27J's primary use is expected to be 
for direct support of the Army, it would also be available for movement 
of cargo in the common user pool. 

New Portfolio Management Initiative Offers Opportunities to Better 
Manage Airlift Investments: 

In September 2008, the department instituted a new process for helping 
senior leaders make investment decisions, including those for 
airlift.[Footnote 19] Known as capability portfolio management, the new 
process enables the department to develop and manage capabilities, as 
opposed to simply individual programs, and enhance the integration and 
interoperability within and across sets of capabilities. Previously we 
reported that leading commercial companies use portfolio management to 
collectively address all of their respective investments from an 
enterprise level rather than as independent and unrelated initiatives. 
[Footnote 20] This approach, among other things, allows the companies 
to weigh the relative costs, benefits, and risks of potential new 
products and helps the companies balance near-and future-term market 
opportunities. 

According to DOD officials, airlift issues fall under the purview of 
the logistics portfolio and are included in the deployment and 
distribution subgroup, along with sealift and ground transportation. 
Figure 1 shows the major capability areas included in the logistics 
portfolio.

[End of figure] 

The new capability portfolio management directive states that DOD shall 
use capability portfolio management to advise the Deputy Secretary of 
Defense and the heads of DOD components on how to optimize capability 
investments across the defense enterprise and minimize risk in meeting 
the department's capability need in support of strategy. The Under 
Secretary of Defense for Acquisition, Technology and Logistics and the 
Commander of U.S. Transportation Command share responsibilities for 
managing the logistics portfolio. They are expected to identify airlift 
issues, priorities, and capability resources and mismatches (gaps, 
shortfalls, and redundancies). According to officials that assist with 
logistics capability portfolio management activities, logistics 
portfolio managers now have access to the Deputy's Advisory Working 
Group that they may not have had access to before to discuss unresolved 
logistics issues, including the Deputy Secretary of Defense and the 
Vice Chairman of the Joint Chiefs of Staff. 

We believe portfolio management offers DOD an opportunity to address 
the full range of airlift issues, but DOD's implementation thus far has 
not had a big impact on the way airlift assets are managed. Officials 
we spoke with stated that the Under Secretary of Defense for 
Acquisition, Technology and Logistics and U.S. Transportation Command 
continue to focus on activities they were already performing prior to 
the establishment of the portfolio, mainly concerned with new weapon 
system programs and future capabilities but not as much on modification 
programs on legacy aircraft. For example, the U.S. Transportation 
Command has been and continues to be responsible for developing an 
integrated priorities list that details the top new capabilities needed 
and identifying capability gaps and shortfalls for airlift. The Under 
Secretary of Defense for Acquisition, Technology and Logistics 
continues to play an advisory role for addressing these gaps and 
shortfalls. 

Officials stated that to date, the logistics portfolio managers have 
not provided input to recent or upcoming airlift decisions related to 
the appropriate mix of strategic and tactical airlifters, changes in 
modernization programs, C-5 retirements, C-17 production shutdown, and 
changes in the Air Force's roles and missions for airlift. In addition, 
no airlift issues have been brought to the working group for 
resolution. Given this approach, we believe the department is still at 
risk of continuing to develop and acquire new airlift systems and 
modernization programs without knowing whether adequate resources are 
available to complete programs within cost and schedule estimates. 

Conclusions: 

Growing fiscal pressures are forcing DOD leaders to look closely at 
weapon system investments. DOD has to make tough investment and 
programmatic decisions regarding strategic and tactical airlift in the 
near future. However, the path forward is not clear because recently 
completed and ongoing mobility studies lack some crucial information 
that would help department officials make sound airlift investment 
decisions. Namely, the studies do not quantitatively account for the 
increasing tactical role of the C-17, especially in light of the fact 
that C-130s are not capable of delivering heavier equipment demanded by 
our warfighters and that the JFTL, which is envisioned to perform this 
mission, will not be available for 15 years. Further, the studies do 
not explore the possible use of C-27Js in a common user role or the 
impact on the fleet and number of C-130s needed to support Army time- 
sensitive, mission-critical requirements. 

While Congress and DOD appear to have addressed the strategic airlift 
capability gap, some fundamental questions remain: Can the Air Force 
adequately fund the C-5 RERP modification program over the next 5 
years? When should C-5s be retired and how many? And how many C-5s 
would need the AMP modification if some of the aircraft are retired? 
Even larger questions exist for tactical airlift: Are 213 C-17s enough 
to perform both strategic and tactical missions? What are the potential 
impacts on C-17 service life, maintenance, and availability from its 
expected increased use in the future for the tactical airlift of 
heavier and bulkier Army equipment? How will the Air Force meet the 
Army's time-sensitive mission-critical requirements with 40 fewer C-27J 
aircraft? Will there be a fundamental shift in the Air Force's roles 
and mission that would require the Air Force to assume more Army- 
specific missions? Can the department set technically realistic 
requirements for the JFTL and follow an evolutionary acquisition 
strategy that includes selecting mature technologies, normally 
developing increments in less than 5 years and fully funding each 
increment? 

More information is needed to help the department address these 
questions and avoid the unnecessary expenditure of billions of dollars 
on redundant capabilities or a potentially premature C-17 production 
line shutdown. The airlift portfolio management team has the requisite 
authority to address these questions and influence budget decisions, 
but greater attention must be paid to all facets of the airlift life 
cycle--from cradle to grave. Making sound modernization and retirement 
decisions is just as important as deciding when and what type of new 
programs to start. Moreover, approaching these decisions from a 
portfolio perspective rather than on a weapon system by weapon system 
basis and considering new roles and missions for the Air Force may help 
the department strike the right balance for its airlift investments. 

Recommendations for Executive Action: 

We are making five recommendations to help improve DOD's management of 
strategic and tactical airlift assets. We recommend that the Secretary 
of Defense direct: 

* the portfolio management team, consisting of U.S. Transportation 
Command and the Under Secretary of Defense for Acquisition, Technology 
and Logistics, to provide more comprehensive advice to senior leaders 
on the full range of airlift investment decisions, including new 
program starts, modernization efforts, and retirement decisions. This 
would also include identifying alternatives for using existing common 
user aircraft to meet service-specific missions and considering new 
roles and missions for the Air Force; 

* the Office of the Secretary of Defense (Cost Assessment and Program 
Evaluation) and Commander, U.S. Transportation Command to develop a 
specific airlift plan that would identify when C-5s will be retired and 
identify the total number of additional C-17s, if any, that would be 
needed to replace C-5s or perform tactical heavy lift missions until 
the time the JFTL is fielded; 

* the Commander, Air Mobility Command, to determine the appropriate mix 
of C-27Js and C-130s that are needed to meet Army time-sensitive, 
mission-critical requirements and common user pool requirements; 

* the Air Force and Army to reach agreement on plans detailing how Army 
time-sensitive, mission-critical requirements will be addressed and 
prioritized against other Air Force priorities; and: 

* the joint Air Force and Army program office to develop a plan to 
follow an evolutionary approach for developing the JFTL based on DOD 
acquisition policy that includes selecting mature technologies, 
normally developing increments in less than 5 years, and fully funding 
each increment. 

Agency Comments and Our Evaluation: 

DOD provided us with written comments on a draft of this report; these 
are included in appendix II. DOD partially concurred with all five 
recommendations, stating that it either has plans and processes in 
place or ongoing efforts to address our concerns. During the course of 
our review, DOD officials explained the steps they were taking to make 
strategic and tactical airlift decisions, but in some cases did not 
provide us with supporting documentation and, in other cases, the plans 
were in the initial stages of development and there was not yet 
sufficient detail for us to determine the extent to which they 
addressed our concerns. Despite the positive actions DOD described, we 
believe that the department's efforts in some cases still fall short 
and that our recommendations are warranted to help guide subsequent 
actions and transition plans to effective implementation. DOD officials 
also provided technical comments on our draft and we revised our report 
where appropriate. 

In response to our first recommendation about the portfolio management 
team providing more comprehensive advice to senior leaders on the full 
range of investment decisions, DOD says it has a structured process in 
place for assessing its mobility capabilities and requirements that 
includes strategic and tactical airlift decisions. We understand that 
DOD has a process in place to make airlift decisions, but they are not 
being made from a comprehensive portfolio management perspective, per 
DOD regulation. DOD officials could not provide us with any evidence 
that the portfolio management team had even discussed airlift issues 
from a portfolio perspective, even though the logistics portfolio began 
as a pilot program for portfolio management 2 years ago. We believe DOD 
portfolio managers need to take a broader perspective on airlift issues 
to ensure that the appropriate amount of attention and resources are 
available to address the most pressing issues for new and legacy 
programs and to avoid unnecessary expenditure of funds for 
modernizations or acquisitions. Therefore, we do not believe that DOD's 
response adequately addresses our recommendation. 

The department agreed with our second recommendation on the need to 
develop a plan for strategic airlift that identifies the number of C-5s 
that will be retired and the number of additional C-17s, if any that 
might be needed. In its comments, DOD stated that the Secretary of the 
Air Force, in coordination with the Office of the Secretary of Defense 
(Cost Assessment and Program Evaluation) and U.S. Transportation 
Command has already developed this plan based on the current level of 
congressional funding for the C-17 and preliminary results of the 
Mobility Capabilities Requirements Study 2016 and the Quadrennial 
Defense Review. Specifically, DOD officials believe an adequate number 
of C-17s have been procured to cover all necessary missions to satisfy 
the National Defense Strategy and will retire some C-5s. We were not 
provided any details about this plan for strategic airlift, the ongoing 
mobility study or the Quadrennial Defense Review to comment on the 
adequacy of the analysis, but believe that a thorough analysis is 
needed for senior leaders to make sound investment decisions. We are 
concerned about the adequacy of the plan because during the course of 
our review, DOD officials told us that the Mobility Capabilities 
Requirements Study 2016 does not specifically quantify the use of the C-
17 in a tactical role or evaluate the impact on its service life 
resulting from the increased use in that regard. In 2007, over 20 
percent of the C-17 missions were for tactical missions and this could 
grow given that it is the only aircraft that is capable of moving 
certain types of equipment within a theater of operations that are too 
large or bulky for the C-130. Further, it is unclear whether DOD has 
identified how many C-5s need the AMP modification since additional C- 
17s are being procured or when and how many C-5s will be retired. In 
addition, we previously reported on deficiencies in how DOD conducted 
its previous mobility capabilities study and we do not know if DOD has 
addressed these flaws in the current study.[Footnote 21] As a result, 
we do not know the extent to which the new study will provide clear 
answers for senior leaders regarding strategic and tactical airlift or 
engender more questions. 

DOD commented that it believes it has fulfilled the requirements for 
our third and fourth recommendations by recently tasking the Air Force 
and Army to determine the appropriate mix of C-27Js and C-130s to 
perform Army time-sensitive, mission-critical requirements and common 
user pool requirements, as well as develop plans detailing how Army 
requirements will be prioritized against Air Force priorities. These 
are good first steps. However, the plans are still in development and, 
according to an Air Force briefing to the Deputy's Advisory Working 
Group, more work needs to be done. Critical details, including a 
concept for employment, a final basing plan, and a decision on the 
maintenance concept will have to be worked out over the next several 
years. These issues have also generated much debate within the 
department and in Congress concerning aircraft quantities and 
employment strategies. As we stated earlier, the Air Force has 
historically had trouble balancing Army priorities with its own and, 
according to the Secretary of Defense, the Air Force will need to 
change its culture to successfully meet both requirements. In addition 
to completing the plans, we believe DOD may need to exert sustained 
oversight by senior leaders, including the portfolio management team, 
to ensure the Air Force is able to perform these missions over the long-
term. 

Finally, DOD believes that it has fulfilled the requirement for our 
fifth recommendation related to using an evolutionary approach for 
developing the JFTL that includes selecting mature technologies, 
developing increments in less than 5 years, and fully funding each 
increment. DOD stated that the Air Force and Army are currently engaged 
in approving a JFTL initial capabilities document and commencing with a 
formal analysis of alternatives to consider all viable options for 
addressing capability gaps. We believe these start-up actions are 
appropriate and, if accomplished according to policy, should provide a 
solid foundation to inform subsequent decisions for a new weapon system 
acquisition program. Our recommendation, however, is geared not only to 
these initial planning steps but also looking forward to the smooth 
transition to system development and effective acquisition program 
management. This recommendation will take several steps and years to 
complete, and we believe senior leaders, including the portfolio 
management team, need to ensure that the JFTL program has a solid 
business case at the start of development with mature technologies, 
adequate funding, and an incremental plan for development. Our previous 
work on many other weapon systems programs[Footnote 22] has shown that 
without these, programs are likely to encounter significant cost and 
schedule growth that will, if realized on the JFTL program, impact the 
department's ability to move medium weight equipment within a theater 
of operations directly to the warfighter. It may also have an impact on 
the C-17 program as these aircraft may be used more frequently than 
planned for tactical missions. We therefore believe that DOD will need 
to take additional steps to be fully responsive to this recommendation.

Appendix I: A Summary of Strategic and Tactical Airlift Systems--
Ongoing and Future Efforts: 

This appendix provides more details on strategic and tactical airlift 
new and modernization programs to expand upon summary information 
provided in the body of this report. We include a brief description of 
each aircraft's mission, program status, and our observations on 
upcoming program decisions. Where applicable, we highlight our recent 
work on some systems. The appendix also includes a funding table for 
each aircraft. Because the fiscal year 2010 budget did not include 
funding projections beyond fiscal year 2010, we used information from 
the Fiscal Year 2010 Defense Budget for funding data related to fiscal 
years 2008 through 2010 and the Fiscal Year 2009 Defense Budget for 
fiscal years 2011 through 2013 when possible. Since the C-5 Reliability 
Enhancement and Reengining Program (RERP) and C-27J programs were 
restructured, we relied on information from the Air Force for fiscal 
years 2011 through 2013 data. The budget information in each table is 
expressed in current (then year) dollars and the totals may not add 
exactly because of rounding. 

Strategic Airlifters: 

The Department of Defense (DOD) uses a mix of modernized C-5s, which 
were manufactured 30 to 40 years ago, and newer C-17s to complete the 
strategic airlift mission. Both strategic airlifters possess 
intercontinental range with aerial refueling and can carry weapons and 
equipment too large for any other DOD aircraft. Each also has some 
complementary characteristics that favor a mixed fleet. The larger C-5 
can carry more cargo than the C-17 and is the only aircraft capable of 
handling some equipment, such as the Army's 74-ton mobile scissors 
bridge. The C-17 is more modern, has a higher mission capable 
rate,[Footnote 23] and is more flexible in that it also provides 
tactical airlift to forward-deployed bases. Figure 2 compares the two 
strategic airlifters.

Mission: 

The C-5 is one of the largest aircraft in the world and is used by DOD 
for strategic airlift purposes. It can carry outsize and oversize cargo 
over intercontinental ranges and can take off or land in relatively 
short distances. With aerial refueling, the aircraft's range is limited 
only by crew endurance. The C-5 can carry nearly all of the Army's 
combat equipment, including large heavy items such as the 74-ton mobile 
scissors bridge. Ground crews can load and off-load the C-5 
simultaneously at the front and rear cargo openings. The landing gear 
system permits lowering of the parked aircraft so the cargo floor is at 
truck bed height to facilitate vehicle loading and unloading. 

Program Status: 

The Air Force acquired a total of 126 C-5s in two production batches. 
Aircraft designated C-5A were built between 1969 and 1974 and given new 
wings in the 1980s.[Footnote 24] Aircraft designated C-5B were built in 
a second production run in the 1980s. Since then, the Air Force has 
retired 14 C-5As and 1 C-5B crashed, leaving a total of 111 C-5 
aircraft (60 C-5As, 49 C-5Bs, and 2 C-5Cs). 

In 1999, the Air Force began modernizing its C-5 aircraft. 
Modifications are intended to improve operational capability while 
improving flight safety, reliability, and maintainability. The two 
primary modifications are as follows[Footnote 25] 

* The Avionics Modernization Program (AMP), which upgrades 
capabilities, including Global Air Traffic Management, navigation and 
safety equipment, modern digital equipment, and an all-weather flight 
control system. 

* The Reliability Enhancement and Reengining Program (RERP), which 
replaces engines and modifies over 70 electrical, fuel, and other 
subsystems. 

Together, these two upgrades were expected to improve the fleet's 
wartime mission capable rate to at least 75 percent, thereby increasing 
payload capability and transportation throughput, and to reduce total 
ownership costs over the life cycle through 2040 by about $14 billion 
in 2008 dollars.[Footnote 26] 

DOD initially expected to spend about $12 billion on the C-5 AMP and 
RERP efforts. However, both modernization efforts experienced cost and 
schedule problems since going into development. AMP development costs 
increased by approximately 20 percent and would have been higher had 
the Air Force not reduced requirements and deferred some development 
activities to other programs. Officials waived 14 operational 
requirements and deferred the correction of 250 deficiencies identified 
during testing, many of which will be addressed and funded in RERP or 
future efforts. In addition, the C-5 RERP experienced a Nunn-McCurdy 
cost breach. The program was restructured and the Air Force now plans 
to RERP 52 aircraft--47 C-5 B aircraft, both C-5 Cs, and 3 aircraft 
that had already been modified during system development and 
demonstration (two C-5Bs and one C-5A). While the Air Force is expected 
to spend $3.4 billion (then-year dollars) less under the restructured 
RERP program, ultimately, less than one-half of the aircraft will be 
modernized and at a much higher unit cost than originally estimated-- 
$160.5 million for both modifications versus $96.1 million originally 
estimated in then-year dollars. DOD now expects that the C-5 AMP 
modification of 112 aircraft and the C-5 RERP modification of 52 
aircraft will reduce total ownership costs over the life cycle through 
2040 by about $8.9 billion base year 2000 dollars. 

According to program officials, as of July 2009, 55 of the C-5s have 
received the AMP modification. The last B model received the 
modification in August 2009. All focus is now on the A models. Many of 
the deficiencies found during testing have been corrected. Other 
deficiencies and waivers will be addressed in the RERP program or a 
planned block upgrade that is slated to begin in fiscal year 2010. 
According to program officials, only 3 C-5 aircraft used during systems 
development and demonstration have received the RERP modification thus 
far. The first production aircraft will enter modification in August 
2009. The Air Force has received low rate initial production approval 
for the first 3 lots, totaling 9 aircraft. The full rate production 
decision is scheduled for December 2010. 

GAO Observations: 

It is unclear whether the Air Force is going to adequately fund the 
restructured C-5 RERP program because the fiscal year 2010 budget does 
not include funding details for the program through 2015. Further, 
program officials could only comment on the fiscal year 2010 budget. On 
the basis of the fiscal year 2009 budget however, DOD's Cost Analysis 
Improvement Group concluded that the restructured C-5 RERP program was 
underfunded by about $294 million then-year dollars across the Future 
Years Defense Plan for fiscal years 2009 through 2013. Approximately 
$250 million then-year dollars less is needed in fiscal years 2009 
through 2011, and $544 million then-year dollars more is needed in 
fiscal years 2012 and 2013. DOD officials stated that if the budget is 
not sufficient to meet agreed-upon quantities, then anticipated price 
breaks would not occur, resulting in increased cost to the program and 
government. 

In June 2009, the Air Force was granted authority by Congress to begin 
retiring C-5A aircraft.[Footnote 27] Air Mobility Command officials 
told us that fiscal and personnel demands require that the command 
limit overall fleet size once warfighting risk is reduced to a 
reasonable level. Therefore, the Air Mobility Command will consider 
retiring C-5s, as the law and requirements allow, on a one-for-one 
basis after 205 C-17s have been procured, to ensure the right 
combination of aircraft and capability is balanced against cost and 
risk. According to program officials, operational testing for an A 
model will take place between October 2009 and January 2010. The final 
report will be issued in July 2010. A decision on whether and when to 
retire C-5s will not likely be made until after the Mobility 
Capabilities and Requirements Study 2016 has been completed. 

If DOD decides to retire C-5A aircraft, it may not need to provide the 
AMP modification to all of its C-5 fleet. The Air Force plans to have 
40 of the 60 C-5A AMP modification kits on contract by the end of 2009 
and at least 8 C-5A models will have actually received the modification 
by that time.

C-17 Globemaster: 

Figure 4: C-17 Globemaster:

[End of figure] 

Mission: 

The C-17 is a multi-engine, turbofan, wide-body aircraft that improves 
the overall capability of the United States Air Force to rapidly 
project, reinforce, and sustain combat forces worldwide. It is used by 
DOD for both strategic and tactical missions. For example, the C-17 is 
capable of rapid strategic delivery of troops and all types of cargo to 
main operating bases or directly to forward bases in the deployment 
area. The aircraft can perform tactical airlift and airdrop missions 
and can also transport ambulatory patients during aeromedical 
evacuations when required. The inherent flexibility and performance of 
the C-17 force improve the ability of the total airlift system to 
fulfill the worldwide air mobility requirements of the United States. 

Program Status: 

The Air Force originally planned to procure 120 C-17s, with the last 
one being delivered in November 2004. The Air Force's current plans are 
to acquire a total of 213 C-17s for $68 billion, with the last one 
being delivered in March 2011. The Air Force has taken delivery of 190 
aircraft through July 2009. This includes one aircraft that is 
dedicated to provide airlift capability to a consortium of European 
nations, effectively setting the Air Force's operational force at 212. 

The Air Force has a number of ongoing improvement efforts for the C-17, 
including: 

* improving C-17 airdrop system operations, 

* integrating an advanced situational awareness and countermeasures 
system, 

* upgrading mission planning by integrating a new joint precision 
airdrop system, 

* replacing the core integrated computer processor, and: 

* providing advanced defensive capability. 

GAO Observations: 

In recent years, the two prominent issues surrounding the C-17 program 
have been determining how many C-17s are needed to meet strategic 
airlift requirements as well as determining when to begin shutting down 
the C-17 production line. Following a C-5 RERP restructuring in 2008, 
the U.S. Transportation Command identified a need for 205 C-17s, 25 
more than were authorized at the time the 2005 Mobility Capabilities 
Study was completed. Subsequent to the study, Congress provided 
additional funding that the Air Force used to procure 10 more C-17s in 
2007, 15 more in 2008, and 8 more in 2009, bringing the total that will 
now be procured to 213. According to Air Mobility Command officials, 
the command will consider retiring C-5s, as the law and requirements 
allow, on a one-for-one basis after 205 C-17s have been procured, to 
ensure the right combination of aircraft and capability is balanced 
against cost and risk. 

According to program officials, a decision when to shut down the C-17 
production line along with the associated costs has not been finalized. 
In our November 2008 report we reported that plans called for the C-17 
production line to shut down in September 2010.[Footnote 28] This was 
based on the Air Force acquiring 205 aircraft. Now that the Air Force 
will be acquiring 213 aircraft, the last delivery is now expected to be 
in March 2011. We also reported that the total cost to shut down the 
line has not been determined. The Air Force estimated the costs to shut 
down production to be $465 million whereas Boeing (the prime 
contractor) estimated $1 billion. Officials reported that while the Air 
Force and Boeing continue to negotiate the final cost to shut down the 
C-17 production line, the Air Force did include $91 million in its 
fiscal year 2010 President's budget submission to begin these 
activities. 

According to a DOD official, the C-17s are currently being employed to 
fill a capability gap existing in the department's ability to airlift 
medium-weight vehicles within a theater of operations using dedicated 
tactical airlifters. DOD officials do not consider the C-17 to be a 
viable long-term solution as it cannot access short, austere, or 
unimproved landing areas in close proximity to combat operations. The 
JFTL is expected to provide this long-term solution; however, the JFTL 
is not expected to be available until 2024.

Tactical Airlifters: 

As of April 2009, DOD's tactical airlift fleet consisted of 92 C-130E 
aircraft, 268 C-130Hs, 53 C-130Js, and 2 C-27Js--a total of 415 
aircraft. DOD plans to retire its aging C-130E fleet by the end of 
fiscal year 2014, and according to its Air Mobility Master Plan, looks 
to meet its tactical airlift needs with a mix of approximately 406 C- 
130H and C-130J airlifters through the end of the next decade. The Army 
and Air Force are working on concepts for the Joint Future Theater Lift 
(JFTL)--an eventual replacement for the C-130H that is projected to be 
capable of carrying most of the Army's large vehicles into forward 
operating locations, which C-130s currently cannot do. Additionally, 
the Joint Requirements Oversight Council has validated the Army's time- 
sensitive, mission-critical resupply requirements that provide the 
basis for the Joint Cargo Aircraft program to procure 38 C-27Js. These 
missions are comprised of relatively small payloads that are needed in 
forward locations within tight time frames. Table 8 compares the 
capabilities of the C-130H, C-130J-30, and C-27J airlifters.

Mission: 

The C-130 is the principal combat delivery aircraft for the U.S. 
military and is employed primarily as a tactical airlift aircraft for 
the transport of cargo and personnel within a theater of operation. C- 
130s also have the capability to augment strategic airlift forces, as 
well as support humanitarian, peacekeeping, and disaster relief 
operations. The C-130J is the latest addition to DOD's fleet of C-130 
aircraft, providing performance improvements over legacy aircraft in 
the series. Variants of the C-130J are being acquired by the Air Force, 
Marine Corps, Coast Guard, and several foreign militaries to perform 
their respective missions. 

Program Status: 

The C-130E and C-130H fleets are nearly 30 years old and have serious 
reliability, maintainability, and supportability issues, and some are 
reaching the end of their service life. For example, aircraft 
maintainers discovered severe cracking in the center wing box on some 
aircraft early in fiscal year 2005. The program office recommended 
retiring or grounding aircraft with more than 45,000 flying hours, and 
restricting aircraft with more than 38,000 hours from flying with cargo 
or performing tactical maneuvers. In response to these recommendations, 
the Air Force is using some operations and maintenance funding to 
extend the service life of some C-130 aircraft by 3 to 5 years, 
including part of the C-130E fleet, which the Air Force plans to retire 
by the end of fiscal year 2014. In addition, the Air Force is currently 
funding the replacement of the center wing box on older C-130 aircraft, 
and plans to replace the wing structure on the remainder of the C-130H 
fleet in a later phase of the program. The cost of the replacement is 
approximately $6.5 million per aircraft, and according to Air Force 
officials, the program is meeting all cost, schedule, and performance 
goals. 

The Air Force also has several other modification efforts underway for 
the C-130H fleet that will address known capability shortfalls. Efforts 
include a Large Aircraft Infrared Countermeasures program, a Surface- 
to-Air Fire Look-out Capability modification, and a number of 
communications upgrades. The largest modernization effort is the 
Avionics Modernization Program (AMP) to standardize cockpit 
configurations and avionics, as well as provide for increased 
reliability, maintainability, and sustainability. Initially, the Air 
Force planned to upgrade all C-130E and C-130H aircraft, including 
special operations aircraft. However, after the program entered system 
development in 2001, it experienced funding instability and hardware 
and software integration issues. These problems, as well as an Air 
Force decision to retire C-130E aircraft, triggered a Nunn-McCurdy cost 
breach in February 2007. The program was subsequently restructured to 
include far fewer aircraft--221 instead of 519--and assume less 
developmental risk. Under the revised plan, only a portion of the C- 
130H fleet would receive the modification. Since that time, the 
program's production decision has been delayed 13 months because of 
documentation and software integration problems and senior leadership 
concerns about the program's acquisition strategy. A low rate 
production decision has not been scheduled as the department is 
considering another program restructure. Program officials further 
stated that a second phase of the AMP is now being considered that will 
modernize C-130s not included in the first phase. 

DOD is in the process of procuring 168 C-130J airlifters to replace the 
retiring C-130E fleet. According to program officials, as of July 2009, 
73 C-130J aircraft have been delivered of 117 on contract.[Footnote 29] 
One program official said all C-130J aircraft currently being purchased 
by the Air Mobility Command are the C-130J-30 model which, compared to 
the base model, has an extended fuselage and is capable of carrying 2 
additional cargo pallets, for a total of 8 pallets. The C-130J fleet is 
also receiving a number of upgrades to meet communications, navigation, 
and surveillance, as well as air traffic management requirements. These 
efforts are being funded and developed in partnership with other 
countries as part of the International Cooperative Block Upgrade 
Program.[Footnote 30] A C-130J program official reports that aircraft 
availability rates continue to exceed the fleet standard and are better 
than rates for C-130H models. 

GAO Observations: 

Recently, the Secretary of Defense testified that DOD could use 
"uncommitted" C-130 aircraft to complement C-27Js in order to fulfill 
Army time-sensitive, mission-critical requirements. However, according 
to an Air Force official, the impact to the C-130 fleet of 
supplementing C-27Js in direct support missions is not clear, including 
how it would affect C-130 availability for other missions. The Air 
Force has drafted a concept of employment for direct support of Army 
time-sensitive, mission-critical missions that addresses a number of 
coordination issues between the services, but the potential impact of 
these missions on the C-130 fleet has not been assessed, such as fuel 
costs, maintenance to address potential wear on landing gear and other 
components, and addressing flight restrictions for runway length.

C-27J Joint Cargo Aircraft: 

Figure 6: C-27J Spartan: 

[Refer to PDF for image: photograph]

[End of figure] 

Mission: 

The C-27J Spartan is a mid-range, multifunctional aircraft. Its primary 
mission is to provide on-demand transport of time-sensitive, mission- 
critical supplies and key personnel to forward deployed Army units, 
including those in remote and austere locations. It can also be used 
for humanitarian relief and homeland security efforts. The aircraft is 
capable of carrying up-armored High Mobility Multipurpose Wheeled 
Vehicles and heavy, dense loads such as aircraft engines and 
ammunition. 

Program Status: 

The Joint Cargo Aircraft program began in late 2005 when the Under 
Secretary for Acquisition, Technology and Logistics directed the Army 
and Air Force to merge their requirements for small intra-theater 
airlifters.[Footnote 31] In June 2007 the Under Secretary of Defense 
for Acquisition, Technology and Logistics issued an Acquisition 
Decision Memorandum certifying the program with approval to proceed to 
low rate initial production. This memorandum set the acquisition 
program baseline at 78 aircraft: 54 for the Army and 24 for the Air 
Force. The Army primarily viewed the C-27J as on-call airlift directly 
tied to the tactical needs of ground commanders, sometimes referred to 
as transporting cargo the "last tactical mile." The Air Force planned 
to use its C-27J assets to provide "general support" airlift for all 
users, but also views the delivery of time-sensitive, mission-critical 
Army cargo as its role. 

The joint Army/Air Force program office selected the C-27J as the Joint 
Cargo Aircraft in a full and open competition and awarded a firm-fixed 
price contract to L-3 Communications, Integrated Systems in June 2007. 
Two aircraft of a total of 13 the Army has ordered through fiscal year 
2009 have been delivered and according to program officials are being 
used to conduct training and developmental testing. In May 2009, as 
part of budget deliberations, the Army and Air Force Chiefs of Staff 
agreed to transfer responsibility for the C-27J program to the Air 
Force, along with the task of fulfilling the Army's time-sensitive, 
mission-critical resupply mission. As part of this restructuring, 
program quantities were reduced by about 50 percent, from 78 to 38 
aircraft. The 13 ordered aircraft, including the 2 already delivered, 
will be transferred to the Air Force, who will procure an additional 25 
aircraft between 2010 and 2012. 

C-27J aircraft are currently built in Turin, Italy. Manufacturer Alenia 
Aeronautica (primary sub contractor to L-3 Communications, Integrated 
Systems) had planned to break ground on a manufacturing facility in 
Jacksonville, Florida, in April 2009, but according to an Alenia 
Aeronautica official, this decision has been presently postponed. 
According to program officials, Alenia Aeronautica had planned to 
assemble C-27J aircraft 16 through 78 at the Jacksonville facility, in 
addition to those ordered by foreign customers. With DOD's decision to 
procure fewer aircraft, it is unclear whether Alenia will proceed with 
construction of the facility. 

GAO Observations: 

The Air Force has offered some insight into how it will meet the Army's 
time-sensitive, mission-critical resupply requirement and is in the 
process of further developing concepts of operation and employment for 
the C-27J. Although the service is buying only 38 C-27J aircraft, it is 
investigating possibilities for fulfilling the direct support mission 
requirement at least in part from a common user pool fleet construct. 
For example, an Air Force official said C-130s are already used for 
some time-sensitive, mission-critical operations. The Secretary of 
Defense has indicated that the 38 C-27Js can be complemented by any of 
about 200 "uncommitted" C-130s, which he noted can access 99 percent of 
the landing strips that C-27Js can access.[Footnote 32] However, it is 
unclear if or how such an approach will affect the number of C-130Js 
the service plans to buy, or the availability of C-130 aircraft to meet 
other requirements associated with major combat operations. The 
Mobility Capabilities and Requirements Study 2016 may help shed light 
on this issue. 

There is also concern about the Air Force's commitment to direct 
support of the time-sensitive, mission-critical requirement. Over the 
past several decades, the Air Force has retired its direct support 
assets, including the Vietnam-era C-7 Caribou and an earlier version of 
the C-27. At issue are basic roles and missions philosophies which DOD 
recognizes need to be updated to reflect lessons learned in ongoing 
combat operations. The Secretary of Defense testified in May 2009 that 
there needs to be a change in the Air Force's culture with respect to 
how the direct support mission is accomplished. Similarly, the 
department's Quadrennial Roles and Missions Review Report for January 
2009 notes that the services need to standardize the airlift process by 
sharing aircraft employment and availability data and adjust concepts 
of operations to allow traditionally general support assets to be used 
for direct support and vice versa. However, the Quadrennial Roles and 
Missions Review Report also determined that the service 
responsibilities for intratheater airlift operations were appropriately 
aligned and the option that provided the most value to the joint force 
was to assign the C-27J to both the Air Force and the Army. An Air 
Force official said the service has drafted a platform-neutral concept 
of employment for direct support of the time-sensitive, mission-
critical mission. The vision is to use the capabilities of the entire 
mobility airlift fleet (i.e., C-130, C-17, C-5, Operational Support 
Airlift) to supplement the 38 C-27Js as required in time-sensitive, 
mission-critical operations abroad. 

While the Mobility Capabilities and Requirements Study 2016 and other 
studies consider tactical airlift requirements into the future, 
officials involved with the study have not indicated that they address 
the impact of potential departures from traditional roles and missions 
constructs--such as changing how the services will approach time- 
sensitive, mission-critical resupply. As such, it is not known how 
these changes may affect overall requirements for tactical airlifters. 
Moreover, there is speculation that the 2010 Quadrennial Defense Review 
will establish priorities based on one major combat operation, rather 
than two simultaneous ones. Considered together, these points raise the 
question of how many C-27Js DOD needs.

Mission: 

DOD plans to replace C-130H aircraft and augment the remaining C-130s 
with the Joint Future Theater Lift (JFTL). Currently, it is still at 
the conceptual stage and is not yet a formal acquisition program. The 
Army and Air Force have independently engaged in laboratory efforts to 
develop competitive technology solutions including a large tiltrotor, 
vertical takeoff and landing aircraft, and a versatile fixed wing, 
short takeoff and landing aircraft, respectively.[Footnote 33] A draft 
Initial Capabilities Document notes that the JFTL must be capable of 
transporting current and future medium-weight armored vehicles into 
austere locations with unprepared landing areas. According to an Army 
official, another capability under investigation is the ability to 
operate from naval vessels (seabasing) to enhance access to remote 
areas and to reduce predictability. The JFTL is anticipated to have a 
payload capacity of 20 to 36 tons and a combat mission radius of 500 
nautical miles. The Air Force Air Mobility Command expects the JFTL to 
be fielded sometime around 2024. 

Program Status: 

JFTL concept development became a joint effort in January 2008 
following a decision by the Army and Air Force Chiefs of Staff to merge 
requirements for separate heavy lift efforts in progress at the time. 
[Footnote 34] The Air Force was designated as the administrative lead 
for the development of the Initial Capabilities Document for the JFTL, 
and submitted a draft into DOD's Joint Capability Integration and 
Development System earlier this year; however, the Army did not agree 
with the draft, citing critical disagreements. According to an Army 
program official, a recent general officer meeting between the two 
services appears to have resolved the Army's remaining critical 
comments, and the services could potentially seek approval of the 
Initial Capabilities Document at the Joint Requirements Oversight 
Council by late summer 2009. Both Army and Air Force officials stated 
they would like to have the Initial Capabilities Document validated and 
begin work on the analysis of alternatives in the summer of 2009, to 
provide a sufficient basis for budget deliberations in March 2010. 

Disparate views on requirements are at the heart of the disagreement 
between the services. According to an Army official, there were 
foundational differences in anticipated usage of the aircraft that led 
to initial disagreements between the services. The land component 
(i.e., the Army, Marine Corps, and special operations forces) saw a 
critical need for an airlift capability that would enable 
expeditionary, mounted (i.e. forces deployed with combat vehicles) 
ground operations into access-challenged environments. The airlift 
community was pursuing a larger, longer range transport to better meet 
the current set of traditional airlift missions. The Army official said 
the two perspectives resulted in different technologies and system 
investigations. The land component, led by the Army, has been pursuing 
vertical takeoff and landing concepts that are less infrastructure- 
constrained, allow faster force buildup, and can more easily sustain 
maneuvering forces from either land or sea bases. The Air Force has 
been pursuing advanced lift system technology for turbofan fixed wing 
aircraft to improve operations on short, soft, or rough airfields while 
increasing cruise speed over current tactical transports. However, the 
Army official said development of the JFTL Initial Capabilities 
Document has combined these perspectives into one requirements document 
and served to converge the services into a more cohesive vision of 
future operations. 

Both the Army and Air Force have continued to fund technology 
development efforts that support their previously separate programs. 
Army technology development efforts are focused on a high-efficiency 
tiltrotor concept that could become a candidate for the JFTL once 
requirements are established. According to an Army lab official, the 
aircraft would be nearly as aerodynamically efficient as a fixed wing 
aircraft and would have about the same fuel efficiency as a C-130J. 
While the concept is still "all on paper," the official said no new 
inventions are needed--that the component technologies all have an 
existing lineage and could be practically implemented on an aircraft of 
the size anticipated (the maximum payload would be 36 tons). The Army 
has three contractors or contractor teams working on different 
tiltrotor configurations that could potentially meet the joint 
capability needs. A number of technology development/risk reduction 
efforts, including a tiltrotor test rig and a number of specialized 
studies, have been funded by the Army, Special Operations Command, 
National Aeronautics and Space Administration, Defense Advanced 
Research Projects Agency, and Office of Naval Research. 

An Air Force official said the service's technology development efforts 
are focused on a fixed wing concept that combines speed and agility to 
provide enhanced lift for short takeoffs. According to the Air Force 
official, three contractors have done work on this speed agile concept, 
with one--Lockheed Martin--on contract to develop a demonstrator model. 
The Air Force Research Laboratory has also, in partnership with 
Lockheed Martin, developed the Advanced Composite Cargo Aircraft, which 
utilizes composite materials in the fuselage and tail, and which 
completed a successful test flight in June 2009. An Air Force Research 
Lab official said this technology significantly reduces the number of 
parts needed, as well as tooling and touch labor needs in the 
manufacturing process. He said these processes and materials could 
potentially be used for the JFTL. 

GAO Observations: 

A potential capability gap exists in the department's ability to 
airlift medium-weight vehicles to access-challenged areas within a 
theater of operations using dedicated tactical airlifters. C-17 
aircraft have been employed to transport medium weight vehicles in 
theater, but cannot access austere, short, or unimproved landing areas. 
In 2007 C-17s flew 15,436 tactical sorties, 3,102 of which-- 
approximately 20 percent--involved carrying objects too large for a C- 
130 to carry. Nevertheless, DOD officials do not consider the C-17 to 
be a viable long-term solution given access issues noted above. JFTL is 
expected to provide this long-term solution. 

We believe the JFTL effort presents the department an opportunity to 
address a critical capability gap using the evolutionary, knowledge- 
based approach outlined in DOD acquisition policy. However, DOD 
officials will need to exercise caution to avoid pitfalls we have 
identified in connection with developing new weapon systems, including 
taking a revolutionary versus an evolutionary approach for weapon 
system development; overpromising performance capabilities; and 
understating expected costs, schedules, and risks associated with 
developing and producing the weapon. 

Fielding the new capability may be a challenge for two reasons. First, 
although the services have reached agreement on operational 
requirements in developing the Initial Capabilities Document, the 
potential exists for future disagreements that could adversely affect 
program outcomes. The Army would like a tiltrotor aircraft that can be 
used in direct support of its maneuver and sustainment operations, and 
the Air Force favors a fixed wing aircraft to support common-user needs 
as well as the Army's direct support mission. An Army official said the 
decision to pursue a tiltrotor or a fixed wing aircraft will be made 
during the analysis of alternatives, and that he expected a more 
cooperative relationship between the services once that is decided. 
However, we feel that if such a relationship does not emerge or 
continue throughout system development, program outcomes could be 
jeopardized. Our previous work has found that unstable requirements in 
conjunction with long development cycles can lead to considerable cost 
growth and schedule delays. 

Second, the JFTL was intended to transport medium-weight vehicles, 
including Future Combat Systems vehicles; however, DOD recently 
canceled the manned ground vehicle portion of the program with plans to 
re-launch a new vehicle modernization program incorporating lessons 
learned in recent operations in Iraq and Afghanistan. We believe the 
design of the new vehicles, including size and weight, could be an 
important factor in determining the type of aircraft best suited for 
the JFTL mission, primarily because the Army's tiltrotor concept 
already envisions a rotorcraft much larger than any ever produced. 
However it could be several years before the Army has a good 
understanding of the size and weight of the new vehicles.

GAO Draft Report Dated September 9, 2009: 
GAO-10-67 (GAO Code 120800): 

"Defense Acquisitions: Strategic Airlift Gap Has Been Addressed, But 
Tactical Airlift Plans Are Evolving As Key Issues Have Not Been 
Resolved" 

Department Of Defense Comments To The GAO Recommendations: 

Recommendation 1: The GAO recommends that the Secretary of Defense 
direct the portfolio management team to provide more comprehensive 
advice to senior leaders on the full range of airlift investment 
decisions, including new program starts, modernization efforts, and 
retirement decisions. This would also include identifying alternatives 
for using existing common user aircraft to meet service-specific 
missions and considering new roles and missions for the Air Force. (p. 
20/GAO Draft Report) 

DOD Response: Partially Concur. The Department has structured processes 
in place for assessing mobility capabilities and requirements that 
include strategic and tactical airlift decisions. AT&L, CAPE, 
USTRANSCOM and other DoD Components participate in these decisions. 

Recommendation 2: The GAO recommends that the Secretary of Defense 
direct the Office of the Secretary of Defense (Cost Assessment and 
Program Evaluation) and Commander, U.S. Transportation Command to 
develop a strategic airlift plan that would identify when C-5s will be 
retired and identify the total number of additional C-17s that would be 
needed to replace C-5s or perform tactical heavy lift missions until 
the time the Joint Future Theater Lift (JFTL) is fielded. (p. 20/GAO 
Draft Report) 

DOD Response: Partially Concur. The Department agrees on the need to 
develop a strategic airlift plan with the details as listed in the 
recommendation. Accordingly, the Secretary of the Air Force, in 
coordination with OSD CAPE and USTRANSCOM, has already developed a 
strategic airlift plan that identifies the retirement of C-5 aircraft 
based on congressional funding of additional C-17s not requested by the 
Department and preliminary findings from the Mobility Capability 
Requirements Study — 2016 and the Quadrennial Defense Review. The 
Department remains confident that it has procured adequate C-17s to 
cover all necessary missions to satisfy requirements of the National 
Defense Strategy. Recapitalization of the C-5 fleet is decades away. 
Prior to determining the C-5's replacement, the Department will conduct 
a comprehensive Analysis of Alternatives to fully assess viable 
options. 

Recommendation 3: The GAO recommends that the Secretary of Defense 
direct the Commander, Air Mobility Command, determine the appropriate 
mix of C-27Js and C-130s that are needed to meet Army time-sensitive, 
mission-critical requirements and common user pool requirements. (p. 
20/GAO Draft Report) 

DOD Response: Partially Concur. The Department agrees on the need to 
determine the appropriate mix of C-27Js and C-130s. Accordingly, the 
Secretary of Defense has already tasked the Air Force and the Army to 
determine the appropriate mix of C-27Js and C-130s that are needed to 
meet Army time-sensitive, mission-critical requirements and common user 
pool requirements, thus fulfilling the requirement of this 
recommendation. 

Recommendation 4: The GAO recommends that the Secretary of Defense 
direct the Air Force and Army reach agreement on plans detailing how 
Army time-sensitive, mission-critical requirements will be addressed 
and prioritized against other Air Force priorities. (p. 21/GAO Draft 
Report) 

DOD Response: Partially Concur. The Secretary of Defense has already
tasked the Air Force and the Army to develop plans detailing how Army 
time-sensitive, mission-critical requirements will be addressed and 
prioritized against other Air Force priorities, thus fulfilling the 
requirement of this recommendation. An agreement was reached in the 
plan for USAF Direct Support of US Army Time Sensitive/Mission Critical 
Concept of Employment, approved and signed by Army and Air Force Vice 
Chiefs of Staff effective 13 Sep 09. 

Recommendation 5: The GAO recommends that the Secretary of Defense 
direct the joint Air Force and Army program office develop a plan to 
follow an evolutionary approach for developing the JTFL based on DoD 
acquisition policy that includes selected mature technologies, normally 
developing increments in less than 5 years, and fully funding each 
increment. (p. 21 /GAO Draft Report) 

DOD Response: Partially Concur. The AF and Army are currently engaged in
approving a JFTL Initial Capabilities Document and commencing with a 
formal JCIDS Analysis of Alternatives (AOA) to consider all viable 
options for addressing capability gaps, thus fulfilling the requirement 
of this recommendation.

[23] DOD uses mission capable rate as a measure of an aircraft's 
readiness to perform at least one assigned mission. 

[24] Two C-5As were later modified to carry National Aeronautics and 
Space Administration components and other outsized cargo and were re- 
designated C-5Cs. 

[25] Other modifications include replacing Aft crown skins, the on- 
board monitoring system, and floor panels and troop compartments 
impacted by corrosion; installing the Large Aircraft Infrared 
Countermeasures System and other defensive systems; and updating 
trainer configurations. 

[26] According to DOD, throughput is defined as the amount of work that 
can be performed or the amount of output that can be produced by a 
system or component in a given period of time. For airlifters, it 
refers to the amount of freight or passengers that can be carried by an 
aircraft during a specified time period.

[31] These similar Army and Air Force efforts were designated the 
Future Cargo Aircraft and Light Cargo Aircraft, respectively. 

[32] Army officials said this statement assumed that if the C-130J 
could access an airfield within 50 nautical miles of the point of need, 
then this was sufficient, even if there were landing zones or surfaces 
accessible by the C-27J closer to the point of need. 

[33] The Army is partnered with the Navy, Special Operations Command, 
Defense Advanced Research Projects Agency, and the National Aeronautics 
and Space Administration. A tiltrotor aircraft, such as the V-22, is 
one that operates as a helicopter for takeoffs and landings and, once 
airborne, converts to a turboprop aircraft. 

[34] The Army and Air Force programs were known as Joint Heavy Lift and 
Advanced Joint Air Combat System, respectively.
