Why GAO Did This Study:

The Army is organizing and equipping rapidly deployable Stryker 
brigades as the first step in its planned 30-year transformation. 
Stryker brigades are to help fill a gap in capabilities between 
current heavy and light forces--heavy forces require too much time to 
deploy, and light infantry forces lack the combat power and mobility 
of the heavy forces. The Army has a goal to be able to deploy a 
Stryker brigade anywhere in the world with 4 days.

As part of a series of ongoing reviews of Army transformation, GAO 
assessed the Army’s progress in (1) meeting its deployment goal for 
Stryker brigades and (2) supporting and sustaining a deployed Stryker 
brigade in combat operations.

What GAO Found:

The Army has made significant progress in creating forces that can be 
more rapidly deployed than heavy forces with its medium weight Stryker 
brigades, but it cannot deploy a Stryker brigade anywhere in the world 
within 4 days. Meeting the 4-day worldwide deployment goal of a 
brigade-size force would require more airlift than may be possible to 
allocate to these brigades; at present, it would take from 5 to 14 
days, depending on brigade location and destination, and require over 
one- third of the Air Force’s C-17 and C-5 transport aircraft fleet to 
deploy one Stryker brigade by air. Because airlift alone may not be 
sufficient, the Army is planning to use a combination of airlift and 
sealift to deploy the brigades. However, if sealift were used to 
deploy the Stryker brigades, deployment times to many global regions 
would be significantly longer than the 4-day goal the Army has set for 
itself. 

The Army’s plan for supporting and sustaining Stryker brigades in 
combat operations is still evolving. The Army will not be able to 
finish its support plan until November 2003, when the results from an 
operational evaluation of the first Stryker brigade will be issued. 
Before it can fully implement the support plan, the Army will also 
need to make funding and other decisions relating to implementing some 
of the plan’s logistical support concepts. 

Deployment goals may need modification should the brigades’ design 
significantly change in response to direction from the Office of the 
Secretary of Defense to enhance the brigades’ capabilities.

What GAO Recommends:

GAO recommends that the Secretary of the Army work with the U.S. 
Transportation Command and its components to set realistic deployment 
timelines for the brigades that (1) reflect the use of both airlift 
and sealift, size of the deployed force, brigade location, and 
destination and (2) take into account any organizational or 
operational changes resulting from modifications and enhancements 
directed by the Office of the Secretary of Defense. In commenting on a 
draft of this report, the Department of Defense generally concurred 
with the report.

Congressional Committees:

The capability to rapidly deploy and effectively sustain combat forces 
over distant locations anywhere in the world is a major objective of 
the Army's planned 30-year transformation. According to the Army, 
current heavy forces lack strategic responsiveness and deployability, 
and they have significant logistical support requirements. On the other 
hand, the Army's current light infantry forces can be deployed rapidly 
and are easier to support once deployed, but they lack the combat 
power, survivability, and tactical mobility of the heavy forces. To 
address this gap in capabilities between heavy and light forces, the 
Army is organizing and equipping a rapidly deployable force, called 
Stryker brigades, intended to provide the combatant commanders with 
increased land power options, including the ability to execute and 
sustain early-entry operations, potentially into remote areas of the 
world.[Footnote 1] Stryker brigades will also validate new doctrine and 
organizational structures and develop insights for subsequent 
transformation to the Army's future force--the Objective 
Force.[Footnote 2] To this end, the Army has established a goal to 
deploy a combat capable Stryker brigade (including its 1,000 plus 
vehicles and pieces of equipment as well as 3,900 personnel) anywhere 
in the world within 4 days. Having realistic deployment goals is 
important to the Army for measuring its progress in creating forces to 
meet them, as well as to theater combatant commanders so that these 
forces can be integrated into contingency planning.

This is the sixth in a series of reports identifying key challenges the 
Army faces in implementing its transformation plans. (A list of related 
GAO products appears at the end of this report.) As with the other 
five, we initiated this review under the authority of the Comptroller 
General. Our objectives were to assess the Army's progress in (1) 
meeting its deployment goal for Stryker brigades and (2) supporting and 
sustaining a deployed Stryker brigade in combat operations. We also 
address potential changes in deployment and support plans the Army may 
need to make in response to direction from the Office of the Secretary 
of Defense to enhance the brigades' capabilities. We briefed your 
offices on the results of our work in November and December 2002. This 
report summarizes and updates those briefings and is being provided 
because of your committees' oversight responsibilities for these 
issues.

To conduct our review, we analyzed planning data on military air and 
sea mobility that the U.S. Transportation Command and the Military 
Traffic Management Command developed.[Footnote 3] We also reviewed the 
Army's concepts and plan for supporting Stryker brigades in an 
operational environment. We limited our review of mobility requirements 
to the strategic deployment of the brigades--we plan to address Stryker 
brigades' tactical mobility requirements and capabilities in another 
report we will be issuing later this year.[Footnote 4]

Results in Brief:

The Army has made significant progress in creating brigades that can be 
more rapidly deployed than heavy armored brigades, but it cannot deploy 
a Stryker brigade anywhere in the world within 4 days. By equipping 
Stryker brigades with 19-ton armored vehicles and reducing support 
structure and sustainment requirements, the Army will have achieved 
close to a 50 percent reduction in the brigade's deployment 
requirements compared to that of a heavier brigade equipped with 
Bradley fighting vehicles and Abrams tanks weighing 33 to 68 tons--
along with their large logistical support structure. However, meeting 
the 4-day worldwide deployment goal of a brigade-size force would 
require more airlift than may be possible to allocate to these 
brigades; at present, it would take from 5 to 14 days, depending on 
destination, and require over one-third of the Air Force's C-17 and C-
5 transport aircraft fleet to deploy one Stryker brigade by air. 
Because airlift alone may not be sufficient, the Army is now planning 
to use a combination of airlift and sealift to deploy the brigades. In 
the Stryker brigades, the Army has achieved forces that are more 
rapidly deployable than heavy forces and more lethal and mobile than 
light forces; however, without more realistic deployment goals, the 
brigades cannot be effectively integrated into theater combatant 
commanders' contingency planning efforts.

The Army's plan for supporting and sustaining Stryker brigades in 
combat operations is still evolving and cannot be considered finalized 
until a number of issues are resolved. The Army evaluated the Stryker 
brigades' support and sustainment capabilities for the first time 
during the congressionally mandated operational evaluation that was 
completed at the end of May 2003.[Footnote 5] The results from the 
operational evaluation will not be issued until November 2003, and they 
may lead to adjustments in the Army's plan. Funding decisions relating 
to implementing some of the plan's logistical support concepts, 
including Stryker armored vehicles and digital equipment replacement 
reserves, also will need to be made before the Army can fully implement 
its plan.

In addition, the Secretary of Defense wants modifications to the 
brigades to give them a higher level of combat capability and 
sustainability so that they are capable of being employed independently 
of higher-level command formations and support. Adding capabilities to 
the brigades --such as aviation and air defense--could significantly 
increase deployment and logistical support requirements, potentially 
requiring more time to deploy a Stryker brigade as well as different 
plans for supporting it.

We are making recommendations to the Secretary of the Army for 
examining alternative strategic deployment goals for Stryker brigades 
and setting goals that are based on a brigade's expected deployment 
timelines and possible modifications to the brigades.

In commenting on a draft of this report, the Department of Defense 
generally concurred with the report and stated that the Army continues 
to maintain 96-hour worldwide deployment as an overall program goal for 
Stryker brigade deployment and is working with the U.S. Transportation 
Command to reduce constraints that limit the Army's ability to meet 
that goal. We agree the 96-hour goal is a useful longer-term target and 
the Army should continue to work with the U.S. Transportation Command 
to reduce enroute constraints. However, without deployment timelines 
reflecting near-term deployment variables and alternatives, the Army 
does not have a reasonable baseline from which to measure its progress 
toward achieving its 96-hour goal; nor do the combatant commanders have 
information on expected Stryker brigade deployment capabilities.

Background:

In 1999 the Army announced its intentions to transform its forces over 
a 30-year period into a more strategically responsive force that could 
more rapidly deploy and effectively operate in all types of military 
operations, whether small-scale contingencies or major theater wars. 
Army transformation plans call for the ability to deploy a brigade 
anywhere in the world in 4 days, a division in 5 days, and five 
divisions within 30 days. The first step in this transformation is to 
form and equip six Interim Brigade Combat Teams, now called Stryker 
Brigade Combat Teams, as an early-entry force that can be rapidly 
deployed, supported anywhere in the world, and capable of conducting 
combat operations immediately upon arrival into a theater of 
operations, if required. Initially, the Army established a requirement 
for Stryker brigades of being capable of deploying anywhere in the 
world within 4 days after first aircraft liftoff. The Army has since 
made it a goal or target for the Stryker brigades, rather than a 
requirement, to help set a vision and design metric for developing the 
brigades.

According to the Army's organizational and operational concept for 
Stryker brigades, the brigades are designed to have higher levels of 
strategic and tactical mobility than existing Army forces. 
Strategically, the brigades are being organized, equipped, and 
configured to meet a 96-hour deployment standard. To help achieve the 
envisioned rapid deployability, the Army is developing logistical 
support plans and concepts that will permit Stryker brigades to deploy 
with fewer quantities of supplies and smaller numbers of support 
personnel and equipment than currently exists in heavier brigade-size 
units. At the tactical level, the brigades are to be capable of 
intratheater deployment by C-130 air transport. Key to their increased 
mobility is their primary combat platform, the Stryker armored vehicle. 
According to the Army, the Stryker armored vehicle will fulfill an 
immediate requirement for a vehicle that is air transportable any place 
in the world, arriving ready for combat. The Stryker is an eight-
wheeled armored vehicle that will provide transport for troops, 
weapons, and command and control. The Stryker vehicle weighs about 19 
tons, substantially less than the M1A1 Abrams tank (68 tons) and the 
Bradley fighting vehicle (33 tons), the primary combat platforms of the 
Army's heavier armored units.

The Army selected one light infantry brigade and one mechanized 
infantry brigade at Fort Lewis, Washington, to become the first two of 
six planned Stryker brigades. The Army completed a congressionally 
mandated operational evaluation of the first of these brigades at the 
end of May 2003, and it plans to report the results of the evaluation 
by November 2003. At that time, the Secretary of Defense is to certify 
to Congress whether or not the results of the operational evaluation 
indicate that the Stryker brigade's design is operationally effective 
and operationally suitable, at which time this brigade can be deployed 
overseas for the first time. The Army plans to complete the formation 
of the second of the two Fort Lewis brigades in 2004 and to form four 
more Stryker brigades from 2005 through 2010. The planned locations of 
the next four brigades (see fig. 1) are Fort Wainwright/Fort 
Richardson, Alaska; Fort Polk, Louisiana; Schofield Barracks, Hawaii; 
and a brigade of the Pennsylvania Army National Guard. Based on defense 
planning guidance, the Army is planning for the relocation of one 
Stryker brigade to Europe in fiscal year 2007.

Progress Has Been Made, but the Army Cannot Currently Achieve Its 
Deployment Goal of 4 Days:

Although Stryker brigades will be more rapidly deployable than Army 
heavy armored brigades, the Army cannot currently achieve its goal of 
deploying a Stryker brigade anywhere in the world within 4 days. The 
Army has achieved close to a 50 percent reduction in the Stryker 
brigades' deployment requirements compared to that of a heavier armored 
brigade, but the Stryker brigade's airlift requirements--which include 
moving about 1,500 vehicles and pieces of equipment and 3,900 
personnel--are still sizable. Deployment times for Stryker brigades 
from their planned continental United States, Alaska, and Hawaii home 
stations to any one of several potential overseas locations would range 
from 5 to 14 days, depending on destinations. While the Army set out to 
design Stryker brigades to be a rapidly air deployable force, Army 
officials now recognize that airlift alone will not be sufficient and 
that some combination of airlift and sealift will likely be used to 
deploy the brigades. However, if sealift were used to deploy the 
Stryker brigades, deployment times to many global regions would be 
significantly longer than the 4-day goal the Army has set for itself.

Stryker Brigades' Deployment Requirements One-Half of Heavy Armored 
Brigades' but Still Sizable:

By equipping Stryker brigades with armored vehicles weighing about 19 
tons, the Army has achieved close to a 50 percent reduction in the 
Stryker brigades' deployment requirement compared to that of a heavy 
armored brigade equipped with 68-ton Abram tanks and 33-ton Bradley 
fighting vehicles, along with their larger numbers of support vehicles, 
equipment, and personnel. Deploying a heavy armored brigade would 
require airlifting almost 29,000 tons of armored vehicles, equipment, 
and supplies and about 4,500 personnel. Deploying a Stryker brigade 
would require airlifting about 15,000 tons of vehicles, equipment, and 
supplies and about 3,900 personnel. Consequently, the amount of airlift 
that would be needed to deploy a Stryker brigade would be about one-
half of the airlift aircraft needed to deploy a heavy armored brigade. 
Based on deployment planning assumptions the Army uses, about 243 C-17 
strategic airlift sorties[Footnote 6] would be needed to airlift a 
Stryker brigade, compared to about 478 C-17 sorties needed to airlift a 
heavy armored brigade.

While the airlift requirement of a Stryker brigade is significantly 
less--about one-half that of a heavy armored brigade, moving a 
brigade's over 300 Stryker armored vehicles, over 1,200 trucks, utility 
vehicles, and support equipment, and 3,900 personnel is about twice the 
deployment requirement of an Army light infantry brigade. Deploying an 
Army light infantry brigade would require airlifting about 7,300 tons 
of materiel and about 3,800 personnel, requiring about 141 C-17 airlift 
sorties. Figure 2 shows a comparison of Stryker brigades' airlift 
requirements to that of Army heavy armored and light infantry brigades.

to That of Armored and Light Infantry Brigades:

Airlift Not Sufficient to Meet Army's Four-Day Worldwide Deployment 
Goal for Stryker Brigades:

The Army will likely not have the amount of airlift it would need to 
meet its goal of deploying a Stryker brigade anywhere in the world 
within 4 days. Deployment times from any one of the four planned 
Stryker brigade locations in the continental United States, Alaska, and 
Hawaii to selected representative locations in South America, the 
Balkans, South Asia, South Pacific, and Africa would range from about 5 
days to destinations in South America to about 14 days to destinations 
in Africa.[Footnote 7] The minimum time it would take to airlift a 
Stryker brigade would be about 5 to 6 days to South America and the 
Balkans, 7 days to South Asia and South Pacific regions, and 13 days to 
Africa. While these timelines are short of the Army's 4-day deployment 
goal, meeting them would offer joint task force commanders or theater 
combatant commanders more rapidly deployable forces than currently 
exists in heavy armored brigades and more lethal and mobile forces than 
currently exist in light infantry brigades. Figure 3 shows estimated 
ranges of Stryker brigade air deployment times from the four current 
and planned Stryker brigade locations to selected global regions. (See 
app. III for a summary of Stryker brigade deployment times by origins 
and destinations.):

Selected Global Regions:

According to the U.S. Transportation Command's Stryker brigade air 
mobility deployment analysis, the Army's deployment goal for Stryker 
brigades has significant implications for the U.S. Transportation 
Command and the defense transportation system. According to this 
analysis, the Army must reduce its transportation requirements and 
simultaneously work with the U.S. Transportation Command and the 
services to improve deployment timelines.

A 2002 Rand report of Stryker brigade deployment options, sponsored by 
the U.S. Air Force, also concluded that Stryker brigades cannot be 
deployed by air from the continental United States to distant overseas 
locations in 4 days. The study found that it is possible to achieve 
global air deployment timelines on the order of 1 to 2 weeks by using a 
combination of continental United States based brigades, a Stryker 
brigade forward-based in Germany, and regional preposition sites. 
According to the study, prepositioning of equipment or overseas basing 
of forces is the single most effective way to increase the 
responsiveness of Army forces for operations in key regions.

Under the 2002 Defense Planning Guidance, the Army is planning for the 
relocation of one Stryker brigade to Europe in fiscal year 2007. By 
air, a brigade based in Germany, for example, could reach some global 
regions in less time than it could from the four currently planned 
brigade locations. From Ramstein Air Base in Germany, minimum air 
deployment times to sub-Saharan Africa would be 7 to 9 days, compared 
to a minimum of 13 days to 14 days from the other brigade locations. 
From Germany to the Balkans, it would take 5 days to airlift a Stryker 
brigade, compared to about 6 days to 7 days from the other locations. 
Although the Army recognizes that some prepositioning of Stryker 
brigade equipment overseas would add to a brigade's strategic 
responsiveness and is considering it as a future option, Army officials 
told us that it would be too costly to do so at this time.

Based on our analysis of the U.S. Transportation Command's air 
deployment planning factors and airlift allocation 
assumptions,[Footnote 8] achieving the 5 to 14 day air deployment 
timelines would be difficult because it would require the Air Force to 
dedicate about one-third of its projected 2005 primary strategic 
airlift aircraft fleet of C-17s and C-5s for transporting only one 
Stryker brigade. Obtaining this amount of airlift for deploying one 
Stryker brigade would require allocating 31 percent of the Air Force's 
total 2005 inventory of C-17 aircraft and 38 percent of its C-5 
aircraft inventory.[Footnote 9] Obtaining an airlift allocation larger 
than this would be possible--if airlifting a Stryker brigade is a 
National Command Authority top priority and absent competing demand 
elsewhere for airlift aircraft. Table 1 shows the U.S. Transportation 
Command's estimated airlift allocation[Footnote 10] and the percentages 
of the projected 2005 total airlift inventory of C-17 and C-5 aircraft 
needed to strategically airlift one Stryker brigade.

2005 Needed to Strategically Airlift One Stryker Brigade:

Army Plans to Use a Combination of Airlift and Sealift to Deploy 
Stryker Brigades:

Because it may not always be possible to obtain sufficient airlift to 
deploy an entire Stryker brigade, Army officials anticipate using a 
combination of airlift and sealift to deploy the brigades, although sea 
deployment time would be slower than the Army's 4-day worldwide 
deployment goal to most locations. Army officials told us that current 
plans are to deploy about one-third of a Stryker brigade by air and the 
remainder of the brigade would be deployed by sea. While some areas in 
South America could be reached by a Stryker brigade located at Fort 
Polk, Louisiana, via gulf coast ports in about 4 days, sea deployment 
times to South America and other global regions from the three other 
planned Stryker brigade locations would take longer. For example, 
sailing time for a Fort Lewis-based Stryker brigade from Seattle/
Tacoma, Washington, would be about 10 days to ports in northern regions 
of South America and more than 2 weeks to ports in West Africa. From 
Alaska, sailing time to any of the eight overseas destinations we 
included in this analysis would take from 12 days to 24 days. 
Similarly, sailing times to the Balkans from any one of the four 
planned Stryker brigade locations would take a minimum of 2 weeks to 
over 3 weeks. With a Stryker brigade forward based in Europe, sea 
deployment times to the Balkans from seaports in Germany, for example, 
could be reduced to about 7 days. Figure 3 shows estimated ranges of 
Stryker brigade sailing times from the four current and planned Stryker 
brigade locations to selected global regions. (See app. IV for a 
summary of sea deployment times by origins and destinations.):

Figure 4: Estimated Ranges of Stryker Brigade Sea Deployment Times:

[See PDF for image]

Note: Sea deployment times are sailing days from a port of embarkation 
to arrival at an overseas port of debarkation.

[End of figure]

In addition to the sailing times needed to reach overseas destinations, 
it would take days to transport a Stryker brigade and all of its 
vehicles and equipment from its home installation to a seaport. For 
example, the Stryker brigade to be located in Alaska would need to 
travel about 350 miles by rail or highway from Fort Wainwright, near 
Fairbanks, to seaports in or near Anchorage. In addition, loading and 
unloading cargo transport ships take much longer than loading and off-
loading aircraft. According to Army deployment planning data, it would 
take about 2 days for loading ships and another 2 days to unload them 
after arrival, compared to hours for loading and unloading aircraft. 
Furthermore, many areas of the world in which Stryker brigades are 
anticipated to operate have no access to a seaport, and not all 
seaports would have the capacity to handle large deep-draft vessels. 
Additional time would also be needed for Army forces deployed by sea to 
move from a seaport to an in-land area of operations, although a 
Stryker brigade would be able to move to in-land locations faster than 
a heavy armored brigade because Stryker armored vehicles can be driven 
while heavier armored vehicles and tanks might require rail or truck 
transport. Also, a deployed Stryker brigade would need less time than a 
heavy armored brigade would need to unload at a seaport, assemble, and 
begin operations: Stryker brigades are organized and equipped to begin 
operations soon after arrival in an operational theater, carrying up to 
3 days' supplies of the fuel and ammunition and sustainment items, 
allowing the brigades to immediately conduct a combat mission. This 
contrasts with an Army armored or mechanized brigade, which would need 
days to draw the fuel, ammunition, and other supplies it would need 
before it can begin operations.

Army's Plan for Supporting and Sustaining Stryker Brigades in Combat 
Operations Is Still Evolving:

The Army's plan for supporting and sustaining Stryker brigades in 
combat operations is still evolving and cannot be considered finalized 
until a number of issues are resolved. These issues include the results 
from the operational evaluation of the first brigade, funding 
questions, and decisions relating to implementing some of the plan's 
logistical support concepts.

The Army will not be able to finish its support plan until November 
2003, when results from the operational evaluation of the first Stryker 
brigade will be issued. The Army conducted the operational evaluation 
in April and May 2003 to assess the first Stryker brigade's overall 
operational effectiveness and suitability. The operational evaluation 
included the logistical support plan and processes that augment the 
brigade's limited capabilities to perform basic maintenance, supply, 
and transportation services. To make Stryker brigades easier to deploy 
and support, the Army designed the brigades with a support structure 
that is only about one-third the size of that found in a heavy armored 
brigade. Thus, Stryker brigades do not have the capability to sustain 
operations without the assistance of external support organizations and 
resources. Contractors will provide a key part of this external support 
to service and maintain newly fielded Stryker armored vehicles and 
complex digital command, control, communications, and computer 
equipment. Contractor logistics support will be needed to support the 
Stryker vehicles and digital systems at least until these systems are 
fully fielded. Also, instead of transporting large inventories of 
ammunition spare parts, and other supplies into an area of operation--
as a heavy armored brigade would do--Stryker brigades are to sustain 
themselves in extended operations by having these items delivered from 
numerous locations outside the area of operation, such as Army depots 
and theater support bases, where they will be stored and configured for 
rapid shipment and distribution to the brigades as they are needed.

Because these support and sustainment processes are new concepts and 
key elements of the Army's support plan for Stryker brigades, the Army 
will complete the plan after it has reviewed the results and lessons 
learned from the operational evaluation. Based on the results, the Army 
plans to make any adjustments or modifications it determines are 
necessary before the plan becomes final. Before it can fully implement 
the support plan, the Army will need to determine the cost and decide 
whether it will fund the acquisition of vehicles and equipment 
replacement reserves. The brigades are designed to do only limited 
maintenance for vehicles and equipment on the battlefield; therefore, 
the Army's support plan calls for rapidly evacuating and replacing 
items needing major maintenance or repair with what the Army calls 
ready-to-fight replacements. The plan depends on having in reserve and 
readily available sufficient numbers of vehicles and essential 
equipment, such as digital components, for rapid shipment into an area 
of operation. Before the Army can make a final funding decision, it 
will first need to determine the types, amounts, and total cost of the 
ready-to-fight replacements that would be needed. As of May 2003, the 
Army had not made a final decision as to the number, types, and 
configuration of the ready-to-fight vehicles, nor the method of their 
delivery to an area of operations. Additionally, to reduce the amount 
of materiel that is deployed and stockpiled within an operational 
theater, the Army's Stryker brigade support plan includes measures for 
rapidly distributing directly to the brigades pre-configured loads of 
essential sustainment supplies such as food, repair parts, and 
ammunition, as they are needed. Before the Army can implement the plan, 
it will need to finish the instructions and guidelines that will 
identify the types and amounts of supplies to be distributed in 
configured loads and the locations and facilities (including defense 
supply depots, Stryker brigade installations, and theater support 
bases) where configured loads are to be built and stored. The Army also 
still will need to identify the personnel and obtain the equipment, 
supplies, and funding that will be needed to manage and carry out its 
planned configured load distribution system.

Army's Plans for Deploying and Sustaining Stryker Brigades Could 
Change:

The Army's current plans for deploying and sustaining Stryker brigades 
could change after the Office of the Secretary of Defense (OSD) reviews 
options it directed the Army to provide for enhancing the brigades' 
capabilities. OSD wants the Army to modify the brigades to be more like 
the Objective Force units the Army is developing. OSD has directed the 
Army to present a plan by July 8, 2003, that provides options for 
adding to the brigade's enhanced combined arms capabilities. Currently, 
the brigades do not have capabilities such as aviation and air defense. 
Such changes would enhance the overall organizational effectiveness of 
the brigades, but they also could increase deployment and support 
requirements, potentially making the brigades more difficult to deploy 
by air and to support.

OSD directed the Army to provide options for enhancing the Stryker 
brigades to ensure that they would provide a higher level of combat 
capability and sustainability across a broader spectrum of combat 
operations than those for which they were originally conceived, along 
with the capability of being employed independently of higher-level 
command formations and support. According to OSD, this additional 
capability will result in Stryker brigades that are more prototypical 
of the combined arms Objective Force units the Army is developing and 
would enhance the transformation of the Army by fielding added 
capabilities sooner. OSD has directed the Army not to expend funds in 
fiscal year 2004 for the fifth and sixth Stryker brigades until the 
Army presents a plan to provide options for enhancing all but one of 
the brigades.[Footnote 11] OSD wants the Army to remodel the brigades 
to be distinctively different than their original design, with enhanced 
combined arms capabilities that might include aviation, air defense, 
sensors, and armor.

Many factors--including the numbers, size, and types of equipment--
affect the Stryker brigades' deployment and logistical support 
requirements. Based on the U.S. Transportation Command's deployment-
planning factors, every additional 1,000 tons of weight to be airlifted 
reduces aircraft range by 250 nautical miles and adds another 15 
aircraft loads. If Stryker brigades were redesigned to include an 
aviation unit, for example, transporting the unit's helicopters from 
the continental United States to overseas destinations would most 
likely need to be done by sea, and it would take days to unload them 
after arrival into a theater of operations. In addition, adding 
aviation maintenance personnel and the equipment that is needed to 
support an aviation unit would also substantially increase deployment 
requirements. Once deployed, the requirements for logistical support, 
such as fuel and spare parts, would increase well beyond that for which 
the Army's current Stryker brigade support plan anticipates. 
Furthermore, the Stryker brigades' support structure as currently 
designed does not have the levels of supply and support personnel or 
the necessary equipment to move and distribute the fuel, spare parts, 
and ammunition a brigade would need to support an aviation unit in 
combat operations.

Conclusions:

With the Stryker brigades, the Army has achieved its intent to create 
rapidly deployable yet lethal forces, but currently the brigades' 
requirements for airlift are too large for airlift alone to be a 
practical option for strategically deploying an entire brigade within 
its goal of 4 days. The Army plans to use some combination of strategic 
airlift and sealift, but it has not established strategic deployability 
timelines for a Stryker brigade that reflect the modes of 
transportation to be used, the wide range of deployment times that vary 
in terms of the size of the deployed force, and the brigades' location 
and destination. In addition, deployment goals may need further 
modification should the brigade's organizational and operational design 
significantly change in response to direction from OSD to enhance the 
brigade's capabilities. While the 4-day deployment goal has created a 
strategic purpose and vision, and is serving as a constructive design 
metric for developing the brigades, such a goal is not a realistic 
standard by which to measure the considerable progress the Army is 
making toward creating more rapidly deployable forces. Without 
deployment goals that reflect the wide range of deployment variables 
and alternatives, the Army does not have a reasonable baseline from 
which to measure its progress toward achieving desired deployment 
timelines for Stryker brigades as well as for the future Objective 
Force; nor do the theater combatant commanders have information on 
expected deployment capabilities they would need in order to plan for 
the use of a Stryker brigade in their theater.

Before the first Stryker brigade is certified for overseas deployment, 
the Army will need to complete its support plan and make any necessary 
adjustments or modifications to the plan based on the results of the 
operational evaluation.

Recommendations for Executive Action:

We recommend that the Secretary of the Army examine alternatives to the 
96-hour worldwide deployment goal for Stryker brigades and work with 
the U.S. Transportation Command and its components to set realistic 
deployment timelines for the brigades that:

* reflect the use of both airlift and sealift, the size of the deployed 
force, a brigade's location, and its destination and:

* take into account any organizational or operational changes to the 
brigades resulting from modifications and enhancements directed by OSD.

Agency Comments and Our Evaluation:

In commenting on a draft of this report, the Department of Defense 
generally concurred with the report and stated that the Army continues 
to maintain 96-hour worldwide deployment as an overall program goal for 
Stryker brigade deployment, and is working with the U.S. Transportation 
Command to reduce constraints that limit the Army's ability to meet the 
goal.

In responding to our recommendation that the Secretary of the Army 
examine alternatives to the 96-hour worldwide deployment goal for 
Stryker brigades and work with the U.S. Transportation Command to set 
realistic deployment timelines, the department stated that the Army is 
committed to its 96-hour goal as a target that it needs to continue to 
work toward in order to provide the necessary capabilities to combat 
commanders within required response times. The department noted that 
achieving this goal requires a concerted effort on the part of all 
services and the U.S. Transportation Command to ensure that enroute 
constraints are reduced. We agree that the 96-hour goal is a useful 
longer-term target and that the Army should continue to work in concert 
with the Transportation Command and the other services to achieve it. 
However, we continue to believe other alternatives to the 96-hour goal 
should be considered for measuring progress in the near-term. As we 
noted in the report, the Army cannot currently air deploy a Stryker 
brigade anywhere in the world within 96 hours and if sealift were used 
to deploy the Stryker brigades, deployment times would be significantly 
longer than the 96-hour deployment goal. We believe that without 
deployment timelines reflecting near-term deployment variables and 
alternatives, such as brigade locations and the use of sealift, the 
Army does not have a reasonable baseline from which to measure its 
progress toward achieving its 96-hour deployment goal; nor do the 
combatant commanders have information on expected Stryker brigade 
deployment capabilities. Thus, we continue to believe our 
recommendation has merit.

In responding to our recommendation for setting realistic deployment 
timelines for Stryker brigades that take into account organizational or 
operational changes to the brigades resulting from any modifications 
and enhancements directed by OSD, the department said the Army should 
maintain its 96-hour deployment goal, as it is a goal and not a 
deployment standard. The department also noted that when the results of 
the OSD-mandated study are approved and published, the Army would work 
with the combatant commanders and the U.S. Transportation Command to 
update the standing contingency plans. We agree the Army should work 
with the combatant commanders and the U.S. Transportation Command to 
update contingency plans based on the final outcome of the OSD-mandated 
study. However, if the results of the study significantly increase the 
Stryker brigades' deployment and logistical support requirements, the 
Army would need to reexamine brigade deployment goals as we have 
recommended.

Appendix I contains the full text of the department's comments.

Scope and Methodology:

To assess the Army's progress in meeting its 96-hour deployment goal 
for Stryker brigades, we obtained documents and interviewed officials 
from the U.S. Transportation Command, the Air Mobility Command, and the 
Military Traffic Management Command. To determine Stryker brigade air 
deployment times and airlift allocation estimates, we used data from a 
U.S. Transportation Command's air mobility deployment analysis 
conducted for the Army in April 2002. To determine sea deployment 
times, we analyzed data from the Military Traffic Management Command's 
Transportation Engineering Agency. In addition, we interviewed 
officials and obtained documents from the Army's Deployment Process 
Management Office and from Army headquarters staff elements responsible 
for operations and plans and logistics. We performed site visits to 
Stryker brigade home installations at Fort Lewis, Washington, and Fort 
Richardson and Fort Wainwright, Alaska; we also interviewed U.S. Army I 
Corps and U.S. Army Alaska and Garrison Command officials at these 
locations. We also toured deployment processing and airfield facilities 
and obtained information about infrastructure improvements planned at 
these locations to validate key assumptions of the U.S. Transportation 
Command's air mobility analysis regarding air deployment infrastructure 
capabilities. We did not visit Fort Polk, Louisiana; Schofield 
Barracks, Hawaii; or the Pennsylvania National Guard. These locations 
are the last three of the six-planned Stryker brigades that are to be 
formed from 2006 through 2010. Because it is not planned to become 
operational until 2010, we excluded from our review the planned 
Pennsylvania National Guard Stryker brigade. We also did not consider 
possible future developments in lift assets such as High Speed Vessels 
or Ultra Heavy Lift Aircraft in our assessment of Stryker brigade 
deployability.

To obtain information on the Army's plan for supporting Stryker 
brigades in combat operations, we analyzed Army information on the 
organizational design and operational concepts for Stryker brigades to 
gain an understanding of the logistical challenges of supporting and 
sustaining the brigades. We interviewed officials at Fort Lewis and 
U.S. Army Alaska for information relating to support and sustainment 
plans for the first three Stryker brigades. In addition, we reviewed 
documents and interviewed officials from Army headquarters staff 
elements responsible for operations and plans, logistics, and force 
development. We also interviewed and obtained documents from the Army's 
Forces Command, the Combined Arms Support Command, and the Tank-
automotive and Armaments Command to learn about support and sustainment 
options for the Stryker brigades.

Our review was conducted from April 2002 through March 2003 in 
accordance with generally accepted government auditing standards.

We are sending copies of this report to the Secretary of Defense, the 
Secretary of the Army, and the Director of Management and Budget. We 
will also make copies available to others upon request. In addition, 
this report will be available at no charge on the GAO Web site at

DEPUTY UNDER SECRETARY OF DEFENSE FOR LOGISTICS AND MATERIEL READINESS 
3500 DEFENSE PENTAGON WASHINGTON, DC 20301-3500:

JUN 23 2003:

Mr. William M. Solis:

Director, Defense Capabilities and Management U.S. General Accounting 
Office:

Washington, DC 20548:

Dear Mr. Solis,

This is the Department of Defense (DoD) response to the GAO draft 
report, "MILITARY TRANSFORMATION: Realistic Deployment Timelines 
Needed for Army Stryker Brigades," dated May 28, 2003 (GAO Code 
350163IGAO-03801).

The Department generally concurs with the report. The Army continues to 
maintain the 96-hour worldwide deployment as an overall program goal 
for Stryker deployment, and is working with the U.S. Transportation 
Command to reduce constraints that limit the Army's:

ability to meet that goal. Detailed DoD comments on the draft GAO 
recommendations are provided in the enclosure. The DoD appreciates the 
opportunity to comment on the draft report.

Sincerely,

Allen W. Beckett:

Attachment As stated:

GAO DRAFT REPORT DATED MAY 28, 2003 GAO CODE 350163/GAO-03-801:

"MILITARY TRANSFORMATION" Realistic Deployment Timelines Needed for 
Army Stryker Brigades":

DEPARTMENT OF DEFENSE COMMENTS TO THE RECOMMENDATIONS:

RECOMMENDATION 1: The GAO recommended that the Secretary of the Army 
examine alternatives to the 96-hour worldwide deployment goal for 
Stryker brigades and work with the U. S. Transportation Command and its 
components to set realistic deployment timelines for the brigades that 
reflect the use of both airlift and sealift, the size of the deployed 
force, a brigade's location, and its destination. (p. 18/GAO Draft 
Report):

DOD RESPONSE: DOD partially concurs. The Department agrees that the 96-
hour goal should not be construed as a standard. The 96-hour goal is a 
target the Army needs to continue to work to achieve in order to 
provide the necessary capabilities to Combatant Commanders within the 
required response times that they set. The Army is committed to its 96-
hour goal to ensure that the Army is capable of meeting any Combatant 
Commanders' deployment requirement. Achieving this goal requires a 
concerted effort on the part of all services and U. S. Transportation 
Command (TRANSCOM) to ensure that enroute constraints are reduced. 
Examples of these constraints include the number of "hot pads" 
available at aerial points of embarkation (APOEs), most on the ground 
(MOG) constraints at Aerial Points of Debarkation (APODs), and the 
inability to position the Global Reach package (refueling, tanker 
airlift control element (TALCE), maintenance). The Army and TRANSCOM 
continue to pursue methods of overcoming these barriers.

RECOMMENDATION 2: The GAO recommended that the Secretary of the Army 
examine alternatives to the 96-hour worldwide deployment goal for 
Stryker brigades and work with the U. S. Transportation Command and its 
components to set realistic deployment timelines for the brigades that 
take into account any organizational or operational changes to the 
brigades resulting from modifications and enhancements directed by the 
Office of the Secretary of Defense. (p. 18/GAO Draft Report):

DOD RESPONSE: Partially concur. The Army should maintain its 96-hour 
deployment goal as it is a goal and not a deployment standard. As the 
draft report states, the 96-hour goal has provided a most useful 
"forcing function" to define and shape the Interim Force, contributing 
to the Army's developing more rapidly deployable forces. The Army 
remains focused on its requirement to provide the necessary combat 
capabilities to the Combatant Commanders in 96 hours. The Army 
continues to pursue remedies to reducing constraints as mentioned above 
with TRANSCOM. When the results of the OSD-mandated study are approved 
and published, the Army will work with the Combatant Commanders and 
TRANSCOM to update the standing contingency plans.

FOOTNOTES

[1] The Army plans to establish six Stryker brigades. Appendix II lists 
the brigades' locations and their planned initial operational 
capability dates.

[2] Beginning in 2010 and continuing beyond 2030, the Army plans to 
transition to its Objective Force. The Objective Force is the force 
that achieves the objectives of the Army's transformation. This future 
force will capitalize on advances in science and technology enabling 
the Army to equip its forces with significantly advanced systems such 
as the Future Combat System.

[3] The U.S. Transportation Command and its component commands (Air 
Mobility Command, Military Traffic Management Command, and Military 
Sealift Command) manage the Department of Defense's transportation 
system.

[4] Strategic mobility is the movement of forces over long distances, 
such as from the continental United States to overseas locations. 
Tactical mobility is the movement of forces in an operational 
environment over shorter distances within an operational theater. 

[5] The operational evaluation was mandated by the National Defense 
Authorization Act for Fiscal Year 2002, P.L. 107-107 (Dec. 28, 2001).

[6] In air operations, a sortie is defined as an operational flight by 
one aircraft.

[7] For the purpose of our analysis of deployment times we used four of 
the five current and planned brigade locations--Fort Lewis, Alaska, 
Fort Polk, and Hawaii. We treated the Alaska brigade as one brigade 
location, although this brigade will be split-based between Fort 
Richardson and Fort Wainwright. The bulk of the brigade is to be 
located at Fort Wainwright. We did not include the planned Pennsylvania 
National Guard brigade because it is not expected to become operational 
until 2010. 

[8] Some of the significant strategic air mobility and aircraft 
allocation assumptions the U.S. Transportation Command used in its 
analysis include the Stryker brigade is the primary airlift claimant in 
a surge operation; the airlift fleet does not include aircraft withheld 
for maintenance, high priority missions, or training; air mobility 
infrastructure will support 20-minute departure intervals; and 
sufficient reserve augmentation is available to provide support for 
increased airlift requirements. 

[9] According to Air Force budget documents, these are the total 
numbers of C-17 and C-5 aircraft expected to be in the Air Force's 
aircraft inventory through 2005.

[10] According to the U.S. Transportation Command, this allocation is a 
reasonable approximation of the airlift a Stryker brigade could claim 
if it was the principal ground force to move early in a small-scale 
contingency operation. 

[11] The fourth Stryker brigade will be the 2nd Armored Cavalry 
Regiment (Light) located at Fort Polk, Louisiana. According to Army 
plans, this brigade is already being designed to have some of the 
combined arms capabilities that OSD wants the Army to add to the five 
other brigades.
