Considerations in Reviewing the Air Force Proposal to Lease Aerial 
Refueling Aircraft:

Statement of Neal P. Curtin, Director Defense Capabilities and 
Management:

GAO-03-1048T:

Mr. Chairman and Members of the Committee:

I appreciate the opportunity to appear before you today to discuss the 
Air Force's report on the planned lease of 100 Boeing 767 aircraft 
modified for aerial refueling. These aircraft would be known by a new 
designation, KC-767A. Section 8159 of the Department of Defense 
Appropriations Act for fiscal year 2002 authorizes the Air Force to 
lease up to 100 KC-767A aircraft. We received the report required by 
section 8159 when it was sent to the Congress on July 10. We 
subsequently received a briefing from the Air Force and some of the 
data needed to review the draft lease and lease versus purchase 
analysis. However, we were permitted to read the lease for the first 
time on July 18 but were not allowed to make a copy and so have not had 
time to fully review and analyze the terms of the draft lease. As a 
result, my testimony today will be based on very preliminary work. I 
will (1) describe the condition of the current aerial refueling fleet, 
(2) summarize the proposed lease as presented in the Air Force's recent 
report, (3) present our preliminary observations on the Air Force lease 
report, and (4) identify related issues that we believe deserve further 
scrutiny.

To determine the condition of the current fleet, we used data from an 
ongoing study of tanker requirements being done for this committee's 
Subcommittee on Readiness. Specifically, we obtained and analyzed KC-
135 and KC-10 mission capable rates, fleet inventory records, 
utilization records, maintenance records, and other documents; and we 
met with knowledgeable officials at the Air Force's KC-135 Systems 
Program Directorate at Tinker Air Force Base in Oklahoma and the Air 
Mobility Command at Scott Air Force Base in Illinois, among other 
officials. To summarize and analyze the report of the proposed lease, 
we reviewed the report, initiated our analysis of the draft lease, and 
received a briefing from the Office of the Assistant Secretary of the 
Air Force (Acquisitions), Air Mobility Programs. To identify key issues 
for further scrutiny, we identified issues raised by the Air Force in 
the report of the proposed lease, but we believe the Air Force did not 
explain fully. We also identified additional costs the Air Force 
expects to incur to field the new aircraft.

Background:

While numerous military aircraft provide refueling services, the bulk 
of U.S. refueling capability lies in the Air Force fleet of 59 KC-10 
and 543 KC-135 aircraft. These are large, long-range aircraft that have 
counterparts in the commercial airlines, but which have been modified 
to turn them into tankers. The KC-10 is based on the DC-10 aircraft, 
and the KC-135 is similar to the Boeing-707 airliner. Because of their 
large numbers, the KC-135s are the mainstay of the refueling fleet, and 
successfully carrying out the refueling mission depends on the 
continued performance of the KC-135s. Thus, recapitalizing this fleet 
of KC-135s will be crucial to maintaining aerial refueling capability, 
and it will be a very expensive undertaking.

There are two basic versions of the KC-135 aircraft, designated the KC-
135E and KC-135R. The R model aircraft have been re-fitted with modern 
engines and other upgrades that give them an advantage over the E 
models. The E-model aircraft on average are about 2 years older than 
the R models, and the R models provide more than 20 percent greater 
refueling capacity per aircraft. The E models are located in the Air 
National Guard and Air Force Reserve. Active forces have only R models. 
Over half the KC-135 fleet is located in the reserve components.

The rest of the DOD refueling fleet consists of Air Force HC-and MC-130 
aircraft used by special operations forces, Marine Corps KC-130 
aircraft, and Navy F-18 and S-3 aircraft. However, the bulk of 
refueling for Marine and Navy aircraft comes from the Air Force KC-10s 
and KC-135s. These aircraft are capable of refueling Air Force and 
Navy/Marine aircraft, as well as some allied aircraft, although there 
are differences in the way the KC-10s and KC-135s are equipped to do 
this.

Condition of Aerial Refueling Fleet:

The KC-10 aircraft are relatively young, averaging about 20 years in 
age. Consequently, much of the focus on modernization of the tanker 
fleet is centered on the KC-135s, which were built in the 1950s and 
1960s, and now average about 43 years in age.

While the KC-135 fleet averages more than 40 years in age, the aircraft 
have relatively low levels of flying hours. The Air Force projects that 
E and R models have lifetime flying hours limits of 36,000 and 39,000 
hours, respectively. According to the Air Force, only a few KC-135s 
would reach these limits before 2040, but at that time some of the 
aircraft would be about 80 years old. Flying hours for the KC-135s 
averaged about 300 hours per year between 1995 and September 2001. 
Since then, utilization is averaging about 435 hours per year.

According to Air Force data, the KC-135 fleet had a total operation and 
support cost in fiscal year 2001 of about $2.2 billion. The older E 
model aircraft averaged total costs of about $4.6 million per aircraft, 
while the R models averaged about $3.7 million per aircraft. Those 
costs include personnel, fuel, maintenance, modifications, and spare 
parts.

The Air Force has a goal of an 85 percent mission capable rate. Mission 
capable rates measure the percent of time on average that an aircraft 
is available to perform its assigned mission. KC-135s in the active 
duty forces are generally meeting the 85 percent goal for mission 
capable rates. Data on the mission capable rates for the KC-135 fleet 
are shown in table 1.

Table 1: Mission Capable Rates for KC-135 Aircraft in May 2003:

Component: Active; Number of aircraft: 245; Mission capable rate 
(percent): 85.

Component: Reserve R models; Number of aircraft: 52; Mission capable 
rate (percent): 82.

Component: National Guard R models; Number of aircraft: 115; Mission 
capable rate (percent): 75.

Component: Reserve E models; Number of aircraft: 16; Mission capable 
rate (percent): 75.

Component: National Guard E models; Number of aircraft: 115; Mission 
capable rate (percent): 79.

Source: Air Force data.

[End of table]

For comparison purposes, the KC-10 fleet is entirely in the active 
component, and the 59 KC-10s had an average mission capable rate during 
the same period of 81.2 percent.

By most indications, the fleet has performed very well during the past 
few years of high operational tempo. Operations in Kosovo, Afghanistan, 
Iraq, and here in the United States in support of Operation Noble Eagle 
were demanding, but the current fleet was able to meet the mission 
requirements. Approximately 150 KC-135s were deployed to the combat 
theater for Operation Allied Force in Kosovo, about 60 for Operation 
Enduring Freedom in Afghanistan, and about 150 for Operation Iraqi 
Freedom. Additional aircraft provided "air bridge" support for movement 
of fighter and transport aircraft to the combat theater, for some long-
range bomber operations from the United States, and, at the same time, 
to help maintain combat air patrols over major U.S. cities since 
September 11, 2001.

The Air Force Report on The KC-767A Aircraft Lease:

Section 8159 of the Department of Defense Appropriations Act for fiscal 
year 2002,[Footnote 1] which authorized the Air Force to lease the KC-
767A aircraft, also specified that the Air Force could not commence 
lease arrangements until 30 calendar days after submitting a report to 
the House and Senate Armed Services and Appropriations Committees (1) 
outlining implementation plans and (2) describing the terms and 
conditions of the lease and any expected savings. The Air Force has 
stated that it will not proceed with the lease until it receives 
approval from all of the committees of the New Start 
Notification.[Footnote 2] The Air Force also submitted the report of 
the proposed lease to the committees as required by section 8159. I 
will now summarize the key points that the Air Force made in this 
report to the committees:

* The Air Force pointed out that aerial refueling helps to support our 
nation's ability to respond quickly to operational demands anywhere 
around the world. This is possible because aerial refueling permits 
other aircraft to fly farther, stay aloft longer, and carry more 
weapons, equipment, or supplies.

* The Air Force indicated that KC-135 aircraft are aging and becoming 
increasingly costly to operate due to corrosion, the need for major 
structural repair, and increasing rates of inspection to ensure air 
safety. Moreover, the report indicates that the Air Force believes it 
is incurring a significant risk by having 90 percent of its aerial 
refueling capability in a single, aging airframe.

* The Air Force considered maintaining the current fleet until about 
2040 but concluded that the risk of a "fleet-grounding" event made 
continued operation of the fleet unacceptable, unless it began its re-
capitalization immediately. The Air Force considered replacing the KC-
135 (E model) engines with new engines but rejected this changeover 
since it would not address the key concern of aircraft corrosion and 
other age-related concerns.

* The Air Force eventually plans to replace all 543 KC-135 aircraft 
over the next 30 years and considered lease and purchase alternatives 
to acquire the first 100 aircraft. The Air Force added traditional 
procurement funding to the fiscal year 2004-2009 Future Years Defense 
Program in order that 100 tankers would be delivered between fiscal 
years 2009 and 2016. Conversely, the report states that under the lease 
option, all 100 aircraft could be delivered from fiscal years 2006 to 
2011. To match that delivery schedule under a purchase option, the Air 
Force stated that it would have to reprogram billions of dollars 
already committed to other uses.

* Office of Management and Budget Circular A-94 directs a comparison of 
the present value of lease versus purchase before executing a lease. In 
its report, the Air Force estimated that purchasing would be about $150 
million less than leasing on a net present value basis.

* The Air Force plans to award a contract to a special purpose entity 
created to issue bonds needed to raise sufficient capital to purchase 
the new aircraft from Boeing and to lease them to the Air 
Force.[Footnote 3] The lease will be a three-party contract between the 
government, Boeing, and the special purpose entity. The entity is to 
issue bonds on the commercial market based on the strength of the lease 
and not the creditworthiness of Boeing.

* Office of Management and Budget Circular A-11 requires that an 
operating lease meet certain terms and conditions including a 
prohibition on paying for more than 90 percent of the fair market value 
of the asset over the life of the lease at the time that the lease is 
initiated. The report to Congress states that the Defense Department 
believes the proposed lease meets those criteria.

* If Boeing sells comparable aircraft during the term of the contract 
to another customer for a lower price than that agreed to by the Air 
Force, the government would receive an "equitable adjustment." The 
report also states that Boeing has agreed to a return-on-sales cap of 
15 percent and that an audit of its internal cost structure will be 
conducted in 2011, with any return on sales exceeding 15 percent 
reimbursed to the government.

* According to the report, if the government were to terminate the 
lease, it must do so for all of the delivered aircraft and may 
terminate any planned aircraft for which construction has not begun, 
must give 12-months advance notification prior to termination, return 
the aircraft, and pay an amount equal to 1 year's lease payment for 
each aircraft terminated. If termination occurs before all aircraft 
have been delivered, the price for the remaining aircraft would be 
increased to include unamortized costs incurred by the contractor that 
would have been amortized over the terminated aircraft and a reasonable 
profit on those costs.

* The government will pay for and the contractor will obtain commercial 
insurance to cover aircraft loss and third party liability, as part of 
the lease agreement. Aircraft loss insurance is to be in the amount of 
$138.4 million per aircraft in calendar year 2002 dollars. Liability 
insurance will be in the amount of $1 billion per occurrence per 
aircraft. If any claim is not covered by insurance, the Air Force will 
indemnify the special purpose entity for any claims from third parties 
arising out of the use, operation, or maintenance of the aircraft under 
the contract.

* At the expiration of the lease, the Air Force will return the 
aircraft to the special purpose entity after removing, at government 
expense, any Air Force unique configurations.

* The contractor will warrant that each aircraft will be free from 
defects in materials and workmanship, and the warranty will be of 36 
months duration and will commence after construction of the commercial 
Boeing 767 aircraft, but before they have been converted into aerial 
refueling aircraft. Upon delivery to the Air Force, each KC-767A 
aircraft will carry a 6-month design warranty, 12-month material and 
workmanship warranty on the tanker modification, and the remainder of 
the original warranty on the commercial components of the aircraft, 
estimated to be about 2 years.

Considerations in Reviewing the Proposed Lease:

Because we have only had the Air Force report for a few days, we do not 
have any definitive analytical results. However, we do have a number of 
questions and observations about the report that we believe are 
important for the Congress to explore in reaching a decision on the Air 
Force proposal.

1. What is the full cost to acquire and field the KC767A aircraft under 
the proposed lease (and assuming the exercising of an option to 
purchase at the conclusion of the lease)?

While the report includes the cost of leasing, the report does not 
include the costs of buying the tankers at the end of the lease. The 
report shows a present value of the lease payments of $11.4 billion and 
a present value of other costs, such as military construction and 
operation and support costs of $5.8 billion. This totals to $17.2 
billion. If the option to purchase were exercised, the present value of 
those payments would be $2.7 billion. Adding these costs to the present 
value of the lease payments and other costs, this would total $19.9 
billion in present value terms.

The costs of the leasing plan have also been presented as $131 million 
per plane for the purchase price, with $7.4 million in financing costs 
per plane, both amounts in calendar year 2002 dollars. If the option to 
purchase were exercised, the price paid would be $35.1 million per 
plane in calendar year 2002 dollars. Adding all of these costs 
together, the cost of leasing plus buying the planes at the end of the 
lease would total $173.5 million per plane in calendar 2002 dollars or 
$17.4 billion for the 100 aircraft.

2. How strong is the Air Force's case for the urgency of this proposal?

As far back as our 1996 report, we said that the Air Force needed to 
start planning to replace the KC-135 fleet, but until the past year and 
a half, the Air Force had not placed high priority on replacement in 
its procurement budget. While the KC-135 fleet is old and is 
increasingly costly to maintain due mainly to age-related corrosion, 
there has been no indication that mission capable rates are falling or 
that the aircraft cannot be operated safely. By having 90 percent of 
its refueling fleet in one aircraft type, the Air Force for some years 
now has been accepting the risk of fleet wide problems that could 
ground the entire fleet; it is really a question of how much risk and 
how long the Air Force and the Congress are willing to accept that 
risk.

3. How will the special purpose entity work?

Under the Air Force proposal, the 767 aircraft would be owned by a 
special purpose entity and leased to the Air Force. This is a new 
concept for the Air Force, and the details of the workings of this 
entity have not been presented in detail. It is important for the 
Congress to understand how this concept will work and how the 
government's interests are protected under such an arrangement. For 
example, what audit rights does the government have? Will financial 
records be available for public scrutiny?

4. What process did the AF follow to assure itself that it obtained a 
reasonable price?

Because this aircraft is being acquired under the Federal Acquisition 
Regulations, the Air Force is required to assure itself through market 
analysis and other means that the price it is paying is reasonable and 
fair. To assess this issue, we would need to know how much of the $131 
million purchase price is comprised of the basic 767 commercial 
aircraft and how much represents the cost of modifications to convert 
it to a tanker. There is an ample market for commercial 767s, and the 
Air Force should have some basis for comparison to assess the 
reasonableness of that part of the price. The cost of the modifications 
is more difficult to assess, and the Air Force has not provided us the 
data to analyze this cost. It would be useful for the Congress to 
understand the process the Air Force followed.

5. Does the proposed lease comply with the OMB criteria for an 
operating lease?

Office of Management and Budget Circular A-11 provides criteria that 
must be met for an operating lease. The Air Force report says that the 
proposal complies with the criteria, but the report points out that one 
of the criteria is troublesome for this lease. This criterion, in 
particular, provides that in order for an agreement to be considered an 
operating lease, the present value of the minimum lease payments over 
the life of the lease cannot exceed 90 percent of the fair market value 
of the asset at the inception of the lease. Depending on the fair 
market value used, the net present value of the lease payments in this 
case may exceed 90 percent of initial value. Specifically, if the fair 
market value is considered to include the cost of construction 
financing, then the lease payments would represent 89.9 percent. If the 
fair market value were taken as $131 million per aircraft, which is the 
price the special purpose entity will pay to Boeing, then the lease 
payments would represent 93 percent. We do not have a position at this 
time on which is the more valid approach, but we believe the Air Force 
was forthright in presenting both figures in its report. Congress will 
need to consider whether this is an important issue and which figure is 
most appropriate for this operating lease.

6. Did the Air Force comply with OMB guidelines for lease versus 
purchase analysis in its report?

A-94 specifies how lease versus purchase analysis should be conducted. 
Our preliminary analysis indicates that the Air Force followed the 
prescribed procedures, but we have not yet had time to validate the Air 
Force's analysis or the reasonableness of the assumptions. The Air 
Force reported that under all assumptions and scenarios considered, 
leasing is more expensive than purchasing, but by only about $150 
million under its chosen assumptions. In a footnote, however, the 
report points out that if the comparison were to a multiyear 
procurement, the difference in net present value would be $1.9 billion 
favoring purchase.

7. Why does the proposal provide for as much as a 15 percent profit on 
the aircraft?

The Air Force report indicates that Boeing could make up to 15 percent 
profit on the 767 aircraft. However, since this aircraft is basically a 
commercial 767 with modifications to make it a military tanker, a 
question arises about why the 15 percent profit should apply to the 
full cost. One financial analysis published recently said that Boeing's 
profit on commercial 767s is in the range of 6 percent. Did the Air 
Force consider having a lower profit margin on that portion of the 
cost, with the 15 percent profit applying to the military-specific 
portion? This could lower the cost by several million dollars per 
aircraft.

Other Issues Related to the Lease Proposal:

In addition to the questions and observations presented above on the 
Air Force report to the Congress, we believe there are a number of 
additional considerations that Congress may want to explore, including 
the following:

* What is the status of the lease negotiations? The Air Force has 
informed us that the lease is still in draft and under negotiation. We 
believe it is important for the Congress to have all details of the 
lease finalized and available to assure that there are no provisions 
that might be disadvantageous to the government. Just last Friday, the 
Air Force let us read the draft lease in the Pentagon but has not 
provided us with a copy of it, so we have not had time to review it in 
detail.

* What other costs are associated with this lease agreement? In 
addition to the lease payments, the Air Force has proposed about $600 
million in military construction, and it has negotiated with Boeing for 
training costs and maintenance costs related to the lease agreement 
that could total about $6.8 billion over the course of the lease. In 
addition, AF documents indicate that there are other costs for things 
like insurance premiums (estimated to be about $266 million) and 
government contracting costs.

* Given the cost of the maintenance agreement, how has the Air Force 
assured itself that it received a good price? The Air Force estimates 
that the maintenance agreement with Boeing will cost between $5 billion 
and $5.7 billion during the lease period. It has negotiated an 
agreement with Boeing as part of the lease negotiations, covering all 
maintenance except flight-line maintenance to be done by Air Force 
mechanics. This represents an average of about $50 million per 
aircraft, with each aircraft being leased for 6 years, or over $8 
million per year. We do not know how the Air Force determined that this 
was a reasonable price or whether competition might have yielded a 
better value. A number of commercial airlines and maintenance 
contractors already maintain the basic 767 commercial aircraft.

* What happens when the lease expires? At the end of each 6-year lease, 
the aircraft are supposed to be returned to the owner, the special 
purpose entity, or be purchased by the Air Force for their residual 
value, estimated at about $44 million each in then-year dollars. If the 
aircraft were returned, the Air Force tanker fleet would be reduced, 
and the Air Force would have to find some way to replace the lost 
capability even though lease payments would have paid almost the full 
cost of the aircraft. In addition, the Air Force would have to pay an 
additional estimated $778 million if the entire 100 aircraft were 
returned; this provision is intended to cover the cost of removing 
military-specific items. For these reasons, returning the aircraft 
would probably make little sense, and the Congress would almost 
certainly be asked to fund the purchase of the aircraft at their 
residual value when the leases expire.

* How is termination liability being handled? If the lease is 
terminated prematurely, the Air Force must pay Boeing 1 year's lease 
payment. Ordinarily, under budget scoring rules, the cost of the 
termination liability would have to be obligated when the lease is 
signed. Because this could amount to $1 billion to $2 billion for which 
the Air Force would have to have budget authority, this requirement was 
essentially waived by Section 8117 of the Fiscal Year 2003 Department 
of Defense Appropriation Act. This means that if the lease were 
terminated, the Air Force would have to find the money in its budget to 
pay the termination amount or come to Congress for the appropriation.

* If the purpose of the lease is to "kick-start" replacement of the KC-
135 fleet--as the Air Force has stated--why are 100 aircraft necessary, 
as stipulated under this lease arrangement? The main advantage of the 
lease, as pointed out by the Air Force, is that it would provide 
aircraft earlier than purchasing the aircraft and without disrupting 
other budget priorities. It is not clear, however, why 100 aircraft is 
the right number to do this. Section 8159 authorized up to 100 aircraft 
to be leased for up to 10 years. The Air Force has negotiated a shorter 
lease period, but stayed with the full 100 aircraft to be acquired from 
fiscal years 2006 to 2011. The "kick-start" occurs in the early years, 
and by fiscal year 2008 the Air Force would have 40 new aircraft 
delivered. We do not know to what extent the Air Force (1) considered 
using the lease for some smaller number of aircraft and then (2) 
planned to use the intervening time to adjust its procurement budget to 
begin purchasing rather than leasing. Such an approach would provide a 
few years to conduct the Tanker Requirements Study and the analysis of 
alternatives that the Air Force has said it will begin soon.

In the coming weeks, we will continue to look into these questions in 
anticipation of future hearings by the Senate Armed Services Committee 
and the Senate Commerce Committee.

Mr. Chairman, this concludes my prepared statement. I would be happy to 
answer any questions that you or Members of the Committee may have.
