Why GAO Did This Study: 

The Joint Strike Fighter (JSF) is the Department of Defense’s (DOD) 
most complex and ambitious aircraft acquisition, seeking to 
simultaneously produce and field three different versions of the 
aircraft for the Air Force, Navy, Marine Corps, and eight international 
partners. The total investment required now exceeds $1 trillion—more 
than $300 billion to acquire 2,456 aircraft and $760 billion in life 
cycle operating and support costs, according to program estimates. The 
Ronald W. Reagan National Defense Authorization Act for Fiscal Year 
2005 requires GAO to review the JSF program annually for 5 years. This 
is the fifth and final report under the mandate in which GAO (1) 
determines the program’s progress in meeting cost, schedule, and 
performance goals; (2) assesses manufacturing results and schedule 
risks; and (3) evaluates development test plans, progress, and risks. 
GAO’s work included analyses of a wide range of program documents, cost 
data and interviews with defense and contractor officials. 


What GAO Found: 

JSF development will cost more and take longer than reported to the 
Congress last year, and DOD wants to accelerate procurement. Two recent 
estimates project additional costs ranging from $2.4 billion to $7.4 
billion and 1 to 3 more years to complete development. Despite cost and 
schedule troubles, DOD wants to accelerate JSF procurement by 169 
aircraft from fiscal years 2010 through 2015; this could require up to 
$33.4 billion in additional procurement funding for those 6 years. DOD 
plans to procure hundreds of aircraft on cost-reimbursement contracts, 
magnifying the financial risk to the government. 

Ongoing manufacturing inefficiencies and parts problems have 
significantly delayed the delivery of test assets. The prime contractor 
has extended manufacturing schedules three times and delivered 2 of 13 
test aircraft. The program is still recovering from earlier problems 
that resulted in design changes, late parts deliveries, and inefficient 
manufacturing. The contractor is taking positive steps to improve 
operations, the supplier base, and schedule management. Schedule risk 
analyses could further enhance management insight into problem areas 
and inform corrective actions. Officials expect to deliver all test 
aircraft and fix many problems by 2010. By then, DOD plans to have 
purchased 62 operational aircraft and will be ramping up procurement. 
Procuring large numbers of production jets while still working to 
deliver test jets and mature manufacturing processes does not seem 
prudent, and looming plans to accelerate procurement will be difficult 
to achieve cost effectively. 

DOD’s revised test plan adds a year to the schedule, better aligns 
resources and availability dates, and lessens the overlap between 
development and operational testing, but it still allows little time 
for error discovery and rework. DOD’s decision late in 2007 to reduce 
test aircraft and flight tests adds to risks while any additional 
delays in delivering test aircraft will further compress the schedule. 
The revised plan relies on state-of-the-art simulation labs, a flying 
test bed, and desk studies to verify nearly 83 percent of JSF 
capabilities. Only 17 percent is to be verified through flight testing. 
Despite advances, the ability to so extensively substitute for flight 
testing has not yet been demonstrated. Significant overlap of 
development, test, and procurement results in DOD making substantial 
investments before flight testing proves that the JSF will perform as 
expected. Under the accelerated procurement plan, DOD may procure 360 
aircraft costing an estimated $57 billion before completing development 
flight testing.

What GAO Recommends: 

GAO recommends that DOD (1) report to the congressional defense 
committees on the risks and mitigation strategy for use of cost 
reimbursement contracts for procurement and plans to transition to 
fixed price contracts and (2) ensure that the prime contractor performs 
periodic schedule risk analyses to improve schedule and budget actions. 
DOD agreed to take these actions.

Congressional Committees: 

The Joint Strike Fighter (JSF) is the Department of Defense's (DOD) 
most complex and ambitious aircraft acquisition, seeking to 
simultaneously produce and field three aircraft variants for the Air 
Force, Navy, Marine Corps, and eight international partners. The JSF is 
critical to our nation's plans for recapitalizing the tactical air 
forces and will require a long-term commitment to very large annual 
funding outlays. The total expected investment is now more than $1 
trillion--more than $300 billion to acquire 2,456 aircraft and $760 
billion in life cycle operation and support costs, according to 
official program estimates. 

The Ronald W. Reagan National Defense Authorization Act for Fiscal Year 
2005 requires GAO to review the JSF program annually for 5 
years.[Footnote 1] Previous reports identified opportunities for the 
program to reduce risks and improve chances for more successful 
outcomes. We have expressed concern about the substantial overlap of 
development, test, and production activities and recommended a more 
evolutionary and knowledge-based acquisition strategy with limited 
investment in production aircraft until each variant demonstrates 
required capabilities in flight testing. Our most recent report 
questioned DOD's decision to reduce test aircraft and flight hours and 
recommended that a new comprehensive cost estimate be 
prepared.[Footnote 2] The department has not implemented our 
recommendations and cost and schedule increases have been the result. 
This is the fifth and final report under the mandate in which we (1) 
determine the JSF program's progress in meeting cost, schedule, and 
performance goals; (2) assess plans and risks in manufacturing and 
capacity to accelerate production; and (3) evaluate plans, progress, 
and risks with testing plans and risks in testing activities. 

To conduct this work, we tracked and compared current cost and schedule 
estimates with those of prior years, identified changes, and determined 
causes. We obtained program status reports, manufacturing data, and 
test planning documents. We assessed the program's scheduling estimates 
against best practices. We discussed results to date and future plans 
to complete JSF development and accelerate procurement with DOD, JSF, 
and contractor officials. Some of the cost data used in our report are 
based on cost projections that were current at the time of our review 
rather than the official program of record. Appendix I includes 
additional information about our scope and methodology. We conducted 
this performance audit from June 2008 to March 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. 

Results in Brief: 

JSF development will cost more and take longer than reported to the 
Congress last year, and DOD wants to accelerate procurement believing 
that will more quickly recapitalize tactical air forces. The program 
office estimates that an additional $2.4 billion is needed for cost 
overruns on the air system and engine contracts and for a 1-year 
extension to the development schedule. Its estimate does not include 
funding for the alternate engine program. An independent joint DOD cost 
estimating team identified a need for as much as $7.4 billion in 
additional funding for development through fiscal year 2015 and a 3- 
year schedule extension. This would increase total system development 
costs to $51.8 billion---a 17 percent increase from the April 2008 
estimate--and delay completion of development to October 2016. The 
joint team's cost estimate was higher than the program office's 
estimate because it included the alternate engine effort directed by 
the Congress and made more conservative assumptions about engineer 
staffing levels, software requirements growth, manufacturing labor 
hours, and flight testing. Despite development cost increases and 
schedule delays, DOD officials want to accelerate JSF procurement by 
purchasing an additional 169 aircraft from fiscal years 2010 through 
2015. This would require up to $33.4 billion in additional procurement 
funding for those 6 years and expose the government to additional risk 
from future cost increases because of the contract type. The plan would 
not increase the total JSF quantity through completion, but would buy 
these aircraft earlier than planned. DOD did not estimate the net 
effect this plan would have on future procurement funding to complete 
JSF acquisition. 

Ongoing manufacturing inefficiencies and parts problems have 
significantly delayed the delivery of needed test aircraft, and the 
prime contractor has not yet achieved the levels of learning expected, 
even as the program ramps up production. The contractor has extended 
manufacturing schedules three times and produced 2 of 13 development 
test aircraft. In the past year, budgeted hours to complete work on all 
test aircraft have increased by 40 percent. The program is still 
recovering from earlier problems in development--late release of 
engineering drawings resulting in design changes and delays in 
establishing the supplier base, late part deliveries, and inefficient 
manufacturing line work-arounds where unfinished work is completed out 
of station. The prime contractor has taken steps to improve 
manufacturing, the supplier base, and schedule management. A thorough 
schedule risk analysis could further enhance management insight into 
areas of uncertainty and better inform subsequent actions to correct 
persistent problems, such as schedule slippage and allocation of 
management reserves. Officials expect to deliver all test aircraft and 
address most of these problems by 2010. By that time, DOD plans to have 
procured 62 operational aircraft and will be quickly ramping up 
production. As DOD has a large backlog of production jets on order and 
is still working to deliver test jets and mature manufacturing 
processes, plans to accelerate procurement will be difficult to achieve 
in a cost-effective manner. 

DOD's revised test plan adds an extra year to the schedule, better 
aligns resources and availability dates, and lessens the overlap 
between development and operational testing, but it is still aggressive 
and allows little time for error discovery, rework, and recovery from 
downtime. DOD's decision late in 2007 to reduce the number of 
development test aircraft and to decrease the number of flight tests 
added risk, while any additional delays in delivering test aircraft 
will further compress the schedule. The independent cost team believes 
flight testing will require an additional 2 years to complete and 
suggests more flight hours to test mission systems and the carrier 
variant in particular. The revised plan relies on advanced and robust 
simulation labs, a flying test bed, and analytical studies to verify 
nearly 83 percent of the aircraft's capabilities while only 17 percent 
is to be verified through flight testing. While the labs appear more 
prolific, integrated, and capable than those used in legacy programs, 
the ability to substitute for flight testing has not yet been 
demonstrated. Significant overlap of development, test, and production 
schedules results in DOD making substantial investments before flight 
testing proves that the JSF will perform as expected. Under the 
accelerated procurement plan, DOD may procure 360 aircraft costing an 
estimated $57 billion before completing development flight testing. 
Acquiring large numbers of aircraft before testing successfully 
demonstrates that the design is mature, meets performance requirements, 
and is suitable could result in substantial future cost growth to 
correct deficiencies found during testing. 

To enhance congressional oversight and increase the likelihood of more 
successful program outcomes, we are recommending that the Under 
Secretary of Defense for Acquisition, Technology and Logistics report 
on the JSF's contracting strategy to the congressional defense 
committees by October 1, 2009. This report would include (1) an 
explanation of the remaining program risks and the factors justifying 
the continued use of cost reimbursement contracts for JSF's future low- 
rate production quantities, (2) the program's strategy for managing and 
mitigating risks associated with the use of cost contracts versus fixed-
price contracts, and (3) plans for transitioning to fixed-price 
contracts for production, including time frames and criteria. To 
further maintain confidence that the program is on track to meet 
planned cost, schedule, and performance goals, we are also recommending 
that the JSF Program Office ensure that the prime contractor performs 
periodic schedule risk analyses for the JSF program to provide better 
insight into management reserve, production efficiencies, and schedule 
completion. 

Background: 

The JSF is a joint, multinational acquisition program for the Air 
Force, Navy, and Marine Corps and eight international partners. The 
program began in November 1996 with a 5-year competition between 
Lockheed Martin and Boeing to determine the most capable and affordable 
preliminary aircraft design. Lockheed Martin won the competition, and 
the program entered system development and demonstration in October 
2001. Program goals are to develop and field an affordable, highly 
common family of stealthy, next-generation strike fighter aircraft for 
the Navy, Air Force, Marine Corps, and U.S. allies. 

The JSF is a single-seat, single-engine aircraft, designed to rapidly 
transition between air-to-ground and air-to-air missions while still 
airborne. To achieve its mission, the JSF will incorporate low- 
observable (stealth) technologies, defensive avionics, advanced onboard 
and offboard sensor fusion, internal and external weapons, and advanced 
prognostic maintenance capability. The JSF family consists of three 
variants. The conventional takeoff and landing (CTOL) variant will 
primarily be an air-to-ground replacement for the Air Force's F-16 
Falcon and the A-10 Warthog aircraft, and will complement the F-22A 
Raptor. The short takeoff and vertical landing (STOVL) variant will be 
a multi-role strike fighter to replace the Marine Corps' F/A-18C/D 
Hornet and AV-8B Harrier aircraft. The carrier-suitable variant will 
provide the Navy a multi-role, stealthy strike aircraft to complement 
the F/A-18E/F Super Hornet. DOD is planning to buy a total of 2,456 
JSFs and allies are expected to procure a minimum of 730 CTOL and STOVL 
aircraft. 

Because of the program's sheer size and the numbers of aircraft it will 
replace, the JSF is the linchpin of DOD's long-term plan to modernize 
tactical air forces. It is DOD's largest acquisition program, with 
total cost currently estimated at $300 billion, and the longest in 
planned duration, with procurement projected through 2034. In addition, 
the JSF remains DOD's largest cooperative program.[Footnote 3] Our 
international partners are providing about $4.8 billion toward 
development, and foreign firms are part of the industrial base 
producing aircraft. DOD's funding requirements for the JSF assume 
economic benefits from these foreign purchases in reducing unit costs 
for U.S aircraft. 

Table 1 shows the evolution of DOD's official estimated cost, quantity, 
and deliveries from the initiation of system development in October 
2001 to the current official program of record dated December 2007 and 
submitted to the Congress in April 2008. It depicts quantities reduced 
in the last major program restructure in 2004, the impacts of increased 
costs on unit prices, and the slip in delivering initial operating 
capability to the warfighter.

Notes: Data are from the annual selected acquisition reports that are 
dated in December of each year but are not officially released and 
reported to the Congress until March or April of the following year. 
The December 2003 data reflect the last major restructuring of the 
program. The December 2007 data represent the official program of 
record at the time of our review and was reported to the Congress in 
April 2008. 

Military construction costs have not been fully established, and the 
reporting basis changed over time in these DOD reports. 

[End of table] 

In our March 2008 report,[Footnote 4] we stated that JSF costs would 
likely grow much higher than reported because the program of record at 
that time did not include all acquisition costs (including the 
alternate engine program directed by the Congress), made overoptimistic 
assumptions, and did not fully reflect the mounting cost and schedule 
pressures from manufacturing inefficiencies and compressed time frames 
for completing development. We questioned the Mid-Course Risk Reduction 
Plan adopted by DOD in September 2007 that cut two development test 
aircraft, reduced test flights, and accelerated the reduction in the 
prime contractor's development workforce in order to replenish 
management reserves depleted by design changes and manufacturing 
problems. We recommended that DOD accomplish a full and comprehensive 
estimate of the total program verified by an independent third party 
and revisit the Mid-Course Risk Reduction Plan with an intensive 
analysis of the causes of management reserve depletion, progress 
against the baseline manufacturing schedule, and correction of 
deficiencies in the contractor's earned value management system. DOD 
agreed to make a comprehensive independent cost estimate, but decided 
to go ahead as planned with the Mid-Course Risk Reduction Plan, stating 
that it would monitor and evaluate progress and revise the plan later 
if it failed to achieve expectations. 

More Money and Time Will Be Needed to Complete JSF Development, While 
DOD Plans to Accelerate Procurement: 

Two recent estimates indicate that JSF development will cost more and 
take longer to complete than reported to the Congress in April 2008, 
primarily because of contract cost overruns and extended time to 
complete flight testing. DOD also plans to accelerate aircraft 
procurement over the next 6 years--buying more aircraft sooner than 
planned last year. This new plan will require significantly more 
procurement funding sooner, but officials did not assess its net effect 
on total program costs through completion of JSF acquisition. 

New Estimates Project Rising Costs and Further Delays to Complete JSF 
Development: 

Development costs are projected to increase between $2.4 billion and 
$7.4 billion and the schedule for completing system development 
extended from 1 to 3 years, according to recent estimates--one by the 
JSF Program Office and one by a joint team of Office of the Secretary 
of Defense (OSD), Air Force, and Navy officials.[Footnote 5] Cost 
overruns on both the aircraft and engine contracts, delays in 
manufacturing test aircraft, and a need for a longer, more robust 
flight test program are the primary cost drivers. The joint team's 
estimate is higher than the program office's because it included costs 
for the alternate engine program directed by the Congress and used more 
conservative assumptions based on current and legacy aircraft 
experiences. Program officials contend that funding the program to the 
higher cost estimate is premature and believe processes are in place to 
substantially improve on the test experiences of past programs. 
Regardless, both estimates agree that cost and time to complete 
development have increased from the official program of record at the 
time of our review. (See table 2.) 

Table 2: Estimated Cost and Schedule for System Development: 

Development costs to complete; 
2007 program of record: $7.4 billion; 
JSF Program Office: $9.8 billion; 
Joint estimating team: $14.8 billion[A]. 

Total development costs; 
2007 program of record: $44.4 billion; 
JSF Program Office: $46.8 billion; 
Joint estimating team: $51.8 billion[A]. 

Date to complete development; 
2007 program of record: October 2013; 
JSF Program Office: October 2014; 
Joint estimating team: October 2016. 

Source: GAO analysis of DOD data. 

[A] The joint estimating team only projected costs through fiscal year 
2015. Extending development to October 2016, as the team projects, 
would increase both cost figures. DOD data suggest that 1 year of 
additional flight testing and other government costs could be about 
$700 million. 

[End of table] 

The program office's revised development cost estimate projects an 
additional $2.4 billion and a 1-year extension in the schedule compared 
to the official program of record reported to the Congress. This would 
increase the system development portion of the acquisition program to 
$46.8 billion and delay its completion to October 2014. The cost 
increases primarily resulted from the following factors. 

* $1.2 billion for aircraft development. Program officials declared a 
cost overrun on the prime air system contract because of increased 
labor hours, higher prices, and supply shortages. Included in this 
figure is $200 million to be added to the contractor's management 
reserve.[Footnote 6] Last year, we reported[Footnote 7] that mounting 
cost and schedule pressures depleted reserves much faster than 
anticipated. By summer 2007, the program had spent about two-thirds of 
budgeted funds but had accomplished only half the work required. Since 
then, DOD's efforts to restore reserves and fix manufacturing 
inefficiencies have not fully achieved intended results, requiring 
another cash infusion. 

* $800 million for engine development. According to officials from the 
Defense Contract Management Agency, the engine contractor continued to 
face development problems, which resulted in a contract cost overrun. 
Higher costs for labor and materials, supplier problems, and the rework 
needed to correct deficiencies with the engine blade design discovered 
during ground testing were major contributing factors. 

* $300 million for flight test extension. The program extended system 
development by 1 year to provide more time for development and 
operational flight testing. In April 2008, an operational test review 
team recommended extending the development contract by 1 year. The 
review team considered but dismissed several other options to address 
the schedule problem, including deferring requirements. 

On the other hand, the joint estimating team estimates that it will 
cost $14.8 billion to complete JSF development, $7.4 billion more than 
the official program of record at the time of our review. This would 
increase the total development costs to $51.8 billion from the $44.4 
billion reported to the Congress last year--a 17 percent increase. The 
joint team also projected a 3-year program extension beyond the program 
of record in order to complete system development, 2 years more than 
the new program office estimate. 

The joint team's estimate was $5 billion more than the new program 
office estimate.[Footnote 8] Several factors account for the difference 
between the two estimates. 

* Alternate engine. The joint estimating team included $1.4 billion to 
complete development of an alternate engine for the JSF; the program 
office estimate did not include alternate engine costs. The Congress 
has directed DOD to develop a second source for the JSF engine to 
induce competition and to ensure that one engine's failures would not 
ground all JSFs, thereby reducing operational risks in the future. DOD 
has not wanted to pursue this second engine source and twice removed 
funding from the JSF program line. 

* Engineering staffing. The joint estimating team projected a need for 
the contractor to retain considerably more engineering staff and for 
longer periods of time than the program office estimate to complete 
development, evaluate test results, and correct deficiencies. Releasing 
engineering staff prematurely risks not discovering problems until late 
in development or during fielding, when they would be more expensive to 
address. 

* Software development. The joint estimating team believes that the 
software productivity rate will be less than the program's calculation 
and anticipates much more growth in software requirements. The JSF 
aircraft is expected to require 7.5 million lines of computer code--the 
most by far of any aircraft. By comparison, the F/A-18E/F has only 1.1 
million and the F-22A 2.2 million. Experiences on past acquisitions 
have shown 30 to 100 percent growth in software requirements over time, 
while the JSF Program Office estimate assumed no growth. 

* Flight testing. The joint estimating team projects that flight 
testing will require more time and effort than the program office has 
built into its current schedule. Continuing delays in delivering test 
aircraft are expected to hamper and further compress test schedules. In 
particular, the joint team projects that the two aircraft dedicated to 
carrier suitability tests will be late off the production line, thereby 
delaying test activities. It also projected that the JSF will require 
about 2,700 hours of flight testing for mission systems, significantly 
more than the 1,700 hours that the program office currently estimates. 

* Manufacturing production hours. The joint estimating team projects 
that production span times for the JSF will be longer than the program 
office estimates based on the program's performance to date and 
experience of recent programs, such as the F/A-18 E/F and the F-22A. 
The span time is an indicator of how long the manufacturing effort 
takes and when flight testing can begin. The program office assumes 
that span times will decrease over the course of the development 
contract. We note that span times typically increase during 
development, as was the case for both the B-2 bomber and F-22A 
programs. 

Program officials believe that their estimate is more accurate and that 
providing extra funding to address future risks is premature and does 
not provide incentives for contractors to control costs. The program 
office attributes its lower cost estimate to several factors. First, 
the quantity, quality, and flexibility of the JSF laboratories should 
enable the program to reduce more risks in a laboratory environment, 
rather than through flight testing, which is considerably more 
expensive. In addition, the program's efforts to develop the final 
software system infrastructure early should reduce significant software 
problems later in the program, according to the program office. The 
program office also believes that costs will be lower because progress 
in several key development areas is either matching plans or is ahead 
of where legacy programs were at similar points of time in their 
development. For example, the program is currently reducing engineering 
staff as planned. The program is also producing software at a rate 
significantly higher than that of the F-22A program and is at least 18 
months ahead of where the F-22A program was at a similar point in 
developing mission systems, according to program officials. Officials 
told us that they intend to fund the fiscal year 2010 development 
budget based on the joint team's higher estimate. However, it is not 
clear at this stage which estimate will serve as the basis for future 
budget submissions. 

Much Higher Annual Procurement Funding Required to Accelerate JSF 
Procurement: 

The program office and joint estimating team also projected procurement 
funding requirements for the 6-year period fiscal years 2010-2015 based 
on DOD plans to accelerate procurement of operational aircraft. Through 
this effort, DOD wants to recapitalize tactical air forces sooner and 
mitigate projected fighter shortfalls in the future. Compared to last 
year, this accelerated plan would procure an additional 169 aircraft 
during these 6 years, moving aircraft that had been scheduled for 
procurement beyond 2015 to earlier years. According to the two 
estimates, this plan would require from $21.8 billion to $33.4 billion 
more funding than the official program of record, as shown in table 3. 

Table 3: Projected Procurement Funding Requirements for Fiscal Years 
2010 through 2015:

[End of table] 

The joint team's estimate is higher than the program office's, 
primarily for these reasons: 

* The joint team projected slower gains in production efficiency than 
the program office. Typically, production efficiency is improved and 
unit costs are lowered over time as a workforce becomes more 
experienced building a new product and manufacturing processes are 
honed. 

* The joint team also assumed fewer savings from commonality. 
Commonality--a key selling point for the JSF program--refers to the use 
of the same or similar parts, structures, and subsystems shared by the 
three variants. Greater commonality can save money by decreasing 
development times and facilitating economic order quantities. 

* The team projected higher labor and material costs and longer 
production span times, based on JSF performance to date in 
manufacturing development test aircraft. 

Table 4 shows the additional aircraft and funding requirements for 
DOD's accelerated plan compared to the official program of record. 
These quantities are for the United States only; during this same 
period, the international partners are expected to buy 273 aircraft.

Procurement of Operational Aircraft under Cost Reimbursement Contracts 
to Continue; Increases the Government's Exposure to Risks: 

The JSF program is procuring a substantial number of aircraft on cost 
reimbursement contracts. Cost contracts place most of the risk on the 
buyer--DOD in this case--who is liable to pay more than budgeted should 
labor, material, or other incurred costs be more than expected when the 
contract was signed. JSF officials plan to procure at least the first 
four low-rate production lots under cost reimbursement contracts and to 
transition to fixed-price instruments when appropriate, possibly 
between lots 5 and 7 (fiscal years 2011 to 2013). It is unclear exactly 
how and when this will happen, but the expectation is to transition to 
fixed pricing once the air vehicle has a mature design, has been 
demonstrated in flight tests, and is producible at established cost 
targets. To date, DOD has procured the first three lots for a total of 
30 aircraft and $7.4 billion on cost reimbursement terms. Under the 
accelerated procurement plan, DOD could procure as many as 360 aircraft 
costing about $57 billion through fiscal year 2013 on cost 
reimbursement contracts, as illustrated in figure 1.

[End of figure] 

Cost reimbursement contracts provide for payment of allowable incurred 
costs, to the extent prescribed in the contract. According to the 
Federal Acquisition Regulation, cost reimbursement contracts are 
suitable for use only when uncertainties involved in contract 
performance do not permit costs to be estimated with sufficient 
accuracy to use any type of fixed-price contract.[Footnote 9] Cost 
reimbursement contracts for weapon production are considered 
appropriate when the program lacks sufficient knowledge about system 
design, manufacturing processes, and testing results to establish firm 
prices and delivery dates. In contrast, a fixed-price contract provides 
for a pre-established price, places more of the risk and responsibility 
for costs on the contractor, and provides more incentive for efficient 
and economical performance. 

Procuring up to 360 production aircraft on cost reimbursement 
contracts---nearly 15 percent of the total DOD program--seems to be a 
tacit acknowledgment by DOD and the contractor that knowledge on JSF 
design, production processes, and costs for labor and material is not 
yet sufficiently mature and that pricing information is not exact 
enough for the contractor to assume the risk under a fixed-price 
contract. It also seems to be a consequence of the substantial 
concurrency of development, test, and production built into the JSF 
schedule. Significant overlap of these activities means that DOD is 
procuring considerable quantities of operational aircraft while 
development test aircraft are still on the production line and much in 
advance of testing to prove aircraft performance and suitability. 
Establishing a clear and accountable path to ensure that the contractor 
assumes more of the risk is prudent. We note that the significant ramp 
up in JSF production under the accelerated profile starts with lot 5, 
the fiscal year 2011 procurement of 70 aircraft. 

Continued Manufacturing Inefficiencies Will Make It Difficult for the 
Program to Meet Its Production Schedule: 

Manufacturing of development test aircraft is taking more time, money, 
and effort than planned, but officials believe that they can work 
through these problems and deliver the 11 remaining test aircraft by 
early 2010. However, by that time, DOD may have procured as many as 62 
production aircraft, accumulating a backlog of aircraft to be produced. 
Manufacturing inefficiencies and parts shortages continue to delay the 
completion and delivery of development test aircraft needed for flight 
testing. The contractor has not yet demonstrated mature manufacturing 
processes, or an ability to produce at currently planned annual rates. 
It has taken steps to improve manufacturing, the supplier base, and 
schedule management. However, given the manufacturing challenges, we 
believe that DOD's plan to accelerate production in the near term adds 
considerable risk and will be difficult to achieve in a cost-effective 
manner. 

Time and Money Needed for Manufacturing Development Test Aircraft 
Continue to Increase: 

The prime contractor has restructured the JSF manufacturing schedule 
three times, each time lengthening the time to deliver aircraft to the 
test program. Delays and manufacturing inefficiencies are prime causes 
of contract cost overruns. The contractor has produced two development 
test aircraft--an original non-production representative model and the 
first STOVL aircraft. It now projects delivering the remaining 11 
aircraft in 2009 and early 2010. Problems and delays are largely the 
residual effects from difficulties early in development. The effects of 
the late release of engineering drawings, design changes, delays in 
establishing a supplier base, and parts shortages continue to cause 
delays and force inefficient production line work-arounds where 
unfinished work is completed out of station.[Footnote 10] Data provided 
by the Defense Contract Management Agency and the JSF Program Office 
show continuing critical parts shortages, out-of-station work, and 
quality issues. The total projected labor hours to manufacture test 
aircraft increased by 40 percent just in the past year, as illustrated 
in figure 2.

Performance data for two major cost areas--wing assembly and mate and 
delivery--indicate even more substantial growth. Figure 3 compares the 
increased budgeted hours in the new schedule to last year's estimates. 
The 2007 schedule assumed a steeper drop in labor hours as more units 
are produced and manufacturing and worker knowledge increases; this 
increased efficiency because of learning is typical of production 
programs. The new schedule, based upon actual performance, projects a 
less steep decline in labor hours, indicating lesser gains in worker 
efficiency. As of June 2008, the planned hours for these two major 
stations increased by about 90 percent over the June 2007 schedule, 
which itself had shown an increase from the 2006 schedule.

The overlap in the work schedule between manufacturing the wing and 
mating (connecting) it to the aircraft fuselage has been a major 
concern for several years because it causes inefficient out-of-station 
work. The contractor continues to address this concern, but the new 
schedule indicates that this problem will continue at least through 
2009. One indicator of its persistence is the projected hours for 
building the last test aircraft. As figure 4 shows, estimated labor 
hours increased more than 80 percent from the June 2007 to June 2008 
schedules, and the planned hours for wing assembly and for the mate and 
delivery phases more than tripled.

Prime Contractor Actions to Improve Schedule Management, Manufacturing 
Efficiency, and Supplier Base: 

Our evaluation determined that the prime contractor now has good tools 
and integrated processes in place that should improve its schedule 
management activities and is also implementing actions to improve 
manufacturing efficiency, the delivery of parts, and proactive 
oversight of subcontractors. The effects from these recent actions are 
not yet fully apparent, and the contractor has not yet accomplished its 
own schedule risk assessment that could provide more insight into 
impacts from areas of risk and uncertainty. The coming year will be 
critical for implementing management improvements in order to 
accomplish a firm and effective transition from manufacturing a few 
test aircraft to producing operational aircraft at high annual rates. 

Prime Contractor's Scheduling Management Processes Meet Many Best 
Practices, but Program Risks Are Not Entirely Visible: 

The prime contractor demonstrated to us that its schedule management 
processes largely meet established best practices criteria. With 
improvements implemented in 2008, the contractor's management systems 
meet or partially meet eight of the nine established criteria.[Footnote 
11] For example, the master schedule can identify and track activities 
associated with over 600 projects. It also establishes the critical 
path between activities, allowing the program to examine the impacts of 
schedule delays and determine schedule flexibility. Appendix II 
discusses our examination of the prime contractor's schedule management 
process against best practices criteria in more detail. 

The one area not meeting best practices was related to performing a 
schedule risk analysis, and as a result, the contractor has limited 
insight into areas of risk and uncertainty in the schedule. The prime 
contractor has not conducted its own risk assessment that would (1) 
determine the level of confidence it has in meeting completion dates 
and (2) identify and apportion reserve funds for contingencies. A 
thorough risk analysis could improve management insight and subsequent 
corrective actions on two recurring problem areas in particular: 
schedule slippage and inadequate management reserve levels. Naval Air 
Systems Command officials did accomplish an independent schedule risk 
analysis that indicated that the program could slip more than 2 years 
based on the productivity risks associated with software development 
and assembly of the various airframes as well as the time needed to 
complete all flight testing. Both the contractor and the JSF Program 
Office disputed the findings of the Naval Air Systems Command schedule 
risk analysis primarily because the analysis was done without direct 
involvement of program officials. 

Improvements in Manufacturing and Supplier Base Are Ongoing: 

The prime contractor is implementing changes designed to address the 
manufacturing inefficiencies and parts shortages discussed earlier. 
These include (1) increasing oversight of key subcontractors that are 
having problems, (2) securing long-term raw material purchase price 
agreements for both the prime and key subcontractors, and (3) 
implementing better manufacturing line processes. On this latter point, 
according to program officials, the prime contractor has taken specific 
steps to improve wing manufacturing performance--one of the most 
troublesome workstations. Defense Contract Management Agency officials 
noted that the contractor produced the second STOVL aircraft variant 
with less work performed out of station than for the first STOVL 
aircraft. Also, program office and contractor officials report some 
alleviation of parts shortages and improvements in quality, but also 
believe that the effects from previous design delays, parts shortages, 
and labor inefficiencies will continue to persist over the near term. 

The lag time between taking action and demonstrating improvement may 
partly explain why some manufacturing performance metrics are not 
demonstrating a clear continued rate of quality improvement, as would 
be desirable and expected for a program ramping up annual production 
rates. This lag time may be evident in two important metrics--scrap, 
rework, and repair rates and manufacturing defect rates--both of which 
have increased somewhat since 2006. Program and contracting officials 
point out, however, that while this performance is not desirable, these 
and other metrics compare very favorably with those of prior 
acquisitions at similar stages of development, including the F-16 and F-
22A. 

Supplier costs are expected to make up an even more substantial share 
of total expenses as the program moves further into production. 
According to contractor officials, efforts are focused on maturing the 
supply base and working more closely and directly with key suppliers to 
reduce costs, alleviate parts shortages, and support higher production 
rates. Key suppliers have struggled to develop critical and complex 
parts while others have had problems with limited production capacity. 
For example, the supplier responsible for the advanced electro- 
hydraulic actuation system had delivered parts with missing 
subcomponents and parts that were not built to specifications. The 
major "team mate" supplier responsible for fuselage and tail assembly 
has experienced delays caused by its limited machining capacity. Given 
these supplier issues, manufacturing inefficiencies, and accumulating 
backlog in production, we believe that the program's plans to 
accelerate production in the near term adds considerable risk and will 
be difficult to achieve in a cost-effective manner. 

The JSF's Test Plan Is Improved but Faces Numerous Challenges to 
Complete Development on Time and on Budget: 

DOD will make significant investments--in both dollars and the number 
of aircraft procured--before completing JSF flight testing. DOD's 
proposal to accelerate procurement further increases financial risks in 
a very challenging test environment. DOD's new test plan adds an extra 
year to the schedule and better aligns resources, but is still 
aggressive with little room for error, presenting a formidable 
challenge to complete system development, support initial operational 
testing, and, eventually, a full rate production decision. DOD 
decisions to reduce development test aircraft and flight tests add to 
the risks, while any additional delays in manufacturing test aircraft 
will further compress the schedule. The JSF has just begun development 
flight testing with two test aircraft and has already experienced some 
setbacks--normal in any program, but of special concern when assets are 
minimal. Some in DOD forecast that another 2 or more years beyond the 1-
year extension just approved will eventually be needed to successfully 
prove aircraft performance and complete system development. The 
department has stated that the contractor's state-of- the-art ground 
test labs and a flying test bed will mitigate risks in the flight 
regimen and their use will effectively substitute for flight testing. 
This approach is promising, but not yet proven. 

Significant Investments Made before Development Flight Tests Are 
Completed: 

DOD is investing heavily in procuring JSF aircraft before flight 
testing proves that they will perform as expected. Procuring aircraft 
before testing successfully demonstrates that the design is mature and 
that the weapon system will work as intended increases the likelihood 
of design and requirements changes resulting in subsequent cost growth, 
schedule delays, and performance limitations. Also, systems already 
built and fielded may later require substantial modifications, further 
adding to costs. The uncertain environment as testing progresses is one 
reason why the prime contractor and DOD are using cost reimbursable 
contracts until rather late in procurement. Table 5 depicts planned 
investments--in both dollars and aircraft--prior to the completion of 
development flight testing. Under the accelerated production plan and 
using the lower procurement cost estimate prepared by the program 
office, DOD may procure 360 aircraft at a total estimated cost of $57 
billion before development flight testing is completed. This overlap 
will be further exacerbated should the joint estimating team's 
predictions of higher cost and lengthier schedule prove accurate.

Flight Testing Is Still in Its Infancy and Has Fallen Behind Schedule: 

The JSF program had completed about 2 percent of its development flight 
testing as of November 2008. Figure 5 shows the expected ramp up in 
flight testing with most effort occurring in fiscal years 2010 through 
2012. Past programs have shown that many problems are not discovered 
until flight testing. As such, the program is likely to experience 
considerable cost growth in the future as it steps up its flight 
testing, discovers new problems, and makes the necessary technical and 
design corrections.

While the program has been able to demonstrate basic aircraft flying 
capabilities, it has recently experienced testing delays and has fallen 
behind the flight test plan established in 2007. At the time of our 
review, the program had flown about half of its planned 155 flight 
tests for 2008. The test program currently has two development test 
aircraft and an integrated airborne test bed, with the following 
experiences to date: 

* Sixty-five test flights on the original, non-production 
representative prototype contributed to discoveries in, among other 
things, landing gear door fitting, aerial refueling operations, and 
weapons bay functions. The prototype experienced a 3-month delay 
because of engine bay nacelle vent fan malfunctions that were 
subsequently resolved. 

* Initial testing of the first of 12 production representative 
prototypes began in June 2008--a STOVL variant flown in conventional 
mode. By the time of our review it accumulated 14 test flights 
demonstrating important handling qualities and reducing risks 
associated with, among other things, the landing gear, fuel system 
performance, and STOVL doors operation. Engine problems delayed full 
STOVL testing by 6 months. 

* Thirty-seven flights on the cooperative avionics test bed tested 
mission system software and demonstrated communication and navigation 
capabilities. 

Looking ahead, the program expects to take delivery of the remaining 
development test aircraft during 2009 and early in fiscal year 2010. In 
the same time frame, it also plans to begin flight testing 6 of its 12 
production representative prototype test aircraft (CTOL and STOVL 
aircraft), including the first 2 aircraft dedicated to mission system 
testing. The first carrier variant development test aircraft is 
expected to begin full flight testing--including ship suitability 
testing--in 2010. A fully integrated, mission capable aircraft is not 
expected to enter flight testing until 2012 by which time DOD plans to 
have already purchased 241 aircraft for about $43 billion under cost 
reimbursement contracts. 

Program's Test Plan Extends Development and Relies Heavily on Ground 
Testing and Simulations to Verify Aircraft Performance: 

The JSF Program Office developed a new and improved test plan in the 
spring of 2008 that extended the development period by 1 year, better 
aligned test resources and availability dates, and lessened the overlap 
between development and operational testing. The new plan is still 
aggressive, however, and has little room for error discovery, rework, 
and recovery from downtime should test assets be grounded or otherwise 
unavailable. The sheer complexity of the JSF program--with 7.5 million 
lines of software code, three variants, and multi-mission development-
-suggests that the aircraft will encounter many unforeseen problems 
during flight testing requiring additional schedule to rework. Our past 
work has shown that programs that do not allow sufficient time to 
address the inevitable problems discovered in testing, run a greater 
risk of significant cost increases and schedule delays when problems do 
arise. The joint estimating team noted that the program's flight test 
plan assumed a higher productivity than has been seen on recent flight 
test programs. As such, the joint team believes that flight testing 
will require an additional 2 years to complete beyond the 1 year 
already added to development and suggests that more flight test hours 
will be necessary to test mission systems and the carrier variant in 
particular. 

The Mid-Course Risk Recovery Plan, approved in late 2007, cut two 
development test aircraft, reduced test flights, and relies more on 
ground laboratories and simulations to verify performance, adding 
substantial risk to the program. Our 2008 report[Footnote 12] discussed 
the objections from several prominent DOD offices to the Mid-Course 
Risk Recovery Plan. The Director of Operational Test and Evaluation, 
for example, identified risks in the revised verification strategy and 
cited inadequate capacity to handle the pace of mission testing and 
ship suitability and signature testing. This increases the likelihood 
of not finding and resolving critical design deficiencies until 
operational testing, when it is more costly and disruptive to do so. 

The test plan relies heavily on a series of advanced and robust 
simulation labs and a flying test bed to verify aircraft and subsystem 
performance. Figure 6 shows that 83 percent of the aircraft's 
capabilities are to be verified through labs, the flying test bed, and 
subject matter analysis, while only 17 percent of test points are to be 
verified through flight testing. The JSF program spent $5 billion on 
its system of simulation labs and models. Program officials argue that 
their heavy investment in simulation labs will allow early risk 
reduction, thereby reducing the need for additional flight testing, 
controlling costs, and meeting the key milestones of the program's 
aggressive test plan.

[End of figure] 

The JSF program's simulation labs appear more prolific, integrated, and 
capable than the labs used in past aircraft programs. The program 
utilizes 18 labs for development whereas only 9 were used for the F- 
22A, 7 for the F-18, and 5 for the F-16. According to program 
officials, the greater number of labs allows engineers to work 
simultaneously on different development blocks, reducing bottlenecks 
that may occur in testing. In contrast, engineers of the F-18 and F-22A 
programs had to interrupt or shut down development on one development 
block while they were making corrections to another. Also in contrast 
to past programs, key JSF simulation labs are colocated at a Lockheed 
Martin plant in Fort Worth, Texas. The F-22A program utilized three 
locations and two different companies. According to the program office, 
the colocation of the key testing labs facilitates more seamless 
integration of key aircraft components. Program officials also noted 
that JSF labs use the actual aircraft components to a greater extent 
than labs did in past programs and also have greater software 
processing capacity. This allows for more realistic data, which should 
reduce the need for additional flight testing. Further, the JSF 
utilizes the first fully integrated airborne test bed for mission 
system testing. According to program officials, the test bed's design 
is geospatially proportionate to an actual F-35 aircraft, enhancing its 
ability to accurately verify aircraft performance. 

While the labs appear more prolific, integrated, and complex than those 
used in legacy programs, concerns about their extensive use in 
verifying aircraft performance remain. The extent of the JSF program's 
planned lab use is unprecedented, but the ability to substitute for 
flight testing has not yet been demonstrated. In addition, the labs 
have yet to be fully accredited. Accreditation is required to ensure 
the adequate capability of labs and models to perform verification 
tasks. It is critical that the models behave like aircraft to ensure 
that the system's performance requirements are being verified 
accurately. The program office said that it is on track to complete the 
accreditation of the labs in time to begin verifying system 
performance. However, the Director of Operational Test and Evaluation 
reports that the progress of the accreditation support packages is 
behind schedule and suggests that more flight testing may be needed as 
the accreditation process reveals the limitations of the models. Some 
DOD officials are also concerned that the labs will be understaffed. 
The Director of Operational Test and Evaluation and DOD's joint 
estimating team both reported that the program's current resource plans 
reduce engineering staff too rapidly. Engineering and test personnel 
are critical to analyzing the data generated from the labs. Without 
adequate staff, there is a greater risk that the labs will not be 
sufficiently utilized, which could, in turn, result in schedule delays 
or cost increases. 

Early Operational Assessment Identifies Several Challenges That May 
Have Operational Impact If Not Addressed: 

While the program is projecting that it will meet all key performance 
parameters, most will not be verified through ground and flight testing 
until fiscal years 2010 through 2013. In addition, a 2008 operational 
assessment by the Air Force Operational Test and Evaluation Center 
pointed out several technical challenges that it believes are likely to 
have a severe operational impact if not adequately addressed. While 
some of the report's concerns are not specific requirements, some DOD 
officials believe that the shortfalls may adversely affect the JSF's 
ability to meet warfighter needs. For example: 

* The current F-35 power system may cause excessive damage to runway 
surfaces which could limit its ability to operate in certain locations. 
The program is still evaluating the problem and plans to gather data 
and conduct further studies when full-scale models or actual aircraft 
are available. According to a program official, changes to the 
aircraft's design or to the current concept of operations may be 
needed. The program has alerted the services and believes it will have 
a better understanding of the problem sometime in 2009. 

* Thermal management challenges hamper the ability to conduct missions 
in hot and cold environments. The Director of Operational Test and 
Evaluation reported that an alternative main engine fuel pump to remedy 
this problem is under development but will not be available before the 
low-rate initial production Lot 3, which is likely to affect 
operational testing. The test team aborted a test sortie because of 
high fuel temperatures in June. 

* The JSF's advanced integrated support system aims to improve and 
streamline aircraft logistics and maintenance functions in order to 
reduce life cycle costs. The current integrated support system for the 
JSF prohibits operating two detachments from one squadron 
simultaneously. This limitation will severely affect current operating 
practices, which include dividing one squadron of aircraft into 
subgroups to deploy and operate at different locations. 

Conclusions: 

The JSF is DOD's largest and most complex acquisition program and the 
linchpin of efforts to recapitalize our tactical air forces. It is now 
in its most challenging phase, at a crossroads of a sort. Challenges 
are many--continuing cost and schedule pressures; complex, extensive, 
and unproven software requirements; and a nascent, very aggressive test 
program with diminished flight test assets. Looking forward, the 
contractor plans to complete work expeditiously to deliver the test 
assets, significantly step up flight testing, begin verifying mission 
system capabilities, mature manufacturing processes, and quickly ramp 
up production of operational aircraft. As such, the credibility of the 
program's test plans, manufacturing capacity, and subsequent cost and 
schedule estimates should become more apparent. 

The program must move forward, but given all these challenges, 
accelerating procurement in a cost-reimbursement contract environment-
-where uncertainties in contract performance do not permit costs to be 
estimated with sufficient accuracy to use any type of fixed-price 
contract--places very significant financial risk on the government. 
Accelerating plans also does not equate to an ability to deliver to 
those plans. Because the program's manufacturing processes are still 
maturing and flight testing is still in its infancy, incorporating an 
accelerated production schedule introduces even more risk and 
uncertainty to the program. Our past work has shown that programs that 
make production decisions prior to fully proving a system's design 
through testing and demonstration of mature manufacturing processes 
have an increased risk of design and production changes and retrofits 
of completed aircraft.[Footnote 13] Until the contractor demonstrates 
that it can produce aircraft in a timely and efficient manner, DOD 
cannot fully grasp future funding requirements. DOD needs tangible 
assurance from the prime contractor that it can meet expected 
development and production expectations. By accelerating low-rate 
production quantities before manufacturing and testing processes are 
mature, DOD accepts most of the contractors' production and 
manufacturing inefficiencies. At minimum, the contractor needs to 
develop a detailed plan demonstrating how it can successfully meet 
program development and production goals in the near future within cost 
and schedule parameters. With an improved contracting framework and a 
more reasoned look to the future, the JSF program can more effectively 
meet DOD and warfighter needs in a constrained budget environment. 

Recommendations for Executive Action: 

Given the program's ongoing manufacturing problems and nascent flight 
test program, we believe that moving forward with an accelerated 
procurement plan is very risky. This risk is reflected by the extended 
use of cost reimbursement contracts for low-rate production quantities-
-a contract mechanism that places most of the cost risk on the 
government. As such, to enhance congressional oversight, increase the 
likelihood of more successful program outcomes, and maintain confidence 
that the program is on track to meet planned cost, schedule, and 
performance goals, we recommend that the Secretary of Defense take the 
following two actions: 

1. Direct the Under Secretary of Defense for Acquisition, Technology 
and Logistics to report to the congressional defense committees by 
October 1, 2009. This report should include, at minimum, 

* an explanation of the cost and other risks associated with a cost- 
reimbursable contract as compared to a fixed-price contract for JSF's 
future low-rate production quantities, 

* the program's strategy for managing and mitigating risks associated 
with the use of cost contracts, and: 

* plans for transitioning to fixed-price contracts for production to 
include time frames and criteria. 

2. Direct the JSF Program Office to ensure that the prime contractor 
performs periodic schedule risk analyses for the JSF program to provide 
better insight into management reserve, production efficiencies, and 
schedule completion to allow for corrections as early as possible. 

Agency Comments and Our Evaluation: 

DOD provided us with written comments on a draft of this report. The 
comments are reprinted in appendix III. 

DOD substantively agreed with our first recommendation regarding a 
report to the Congress on contracting strategy, but believed that the 
Under Secretary of Defense for Acquisition, Technology and Logistics 
should be responsible for the report, not the JSF Program Office as 
stated in our draft. As the milestone decision authority, the Under 
Secretary is responsible for approving the contracting strategy, 
contract awards, and the transition to full rate production. We agree 
with DOD and revised the recommendation accordingly. 

DOD also agreed with the second recommendation and will direct that the 
prime contractor perform periodic schedule risk analysis. In 
coordination with the JSF Program Office, the department intends to 
determine an optimum schedule for the contractor that will provide 
insight into JSF cost and schedule to influence key milestones and 
decision making. 

We are sending copies of this report to the Secretary of Defense; the 
Secretaries of the Air Force, Army, and Navy; and the Director of the 
Office of Management and Budget. The report also is available at no 
charge on the GAO Web site at [hyperlink, http://www.gao.gov].

Appendix I: Scope and Methodology: 

To determine the Joint Strike Fighter (JSF) program's progress in 
meeting cost, schedule, and performance goals, we received briefings by 
program and contractor officials and reviewed financial management 
reports, budget documents, annual selected acquisition reports, monthly 
status reports, performance indicators, and other data. We compared 
reported progress with prior years' data, identified changes in cost 
and schedule, and obtained officials' reasons for these changes. We 
interviewed Department of Defense (DOD), JSF Program Office, and 
contractor officials to obtain their views on progress, ongoing 
concerns and actions taken to address them, and future plans to 
complete JSF development and accelerate procurement. This review was 
the fifth and final effort under the mandate of the Ronald W. Reagan 
National Defense Authorization Act for Fiscal Year 2005. We were 
provided sufficient information to make the assessments contained in 
this report. 

In assessing program cost estimates, we compared the official program 
cost estimate in the December 31, 2007, selected acquisition report to 
estimates developed by the JSF program and an independent joint 
estimating team for fiscal years 2010 through 2015. Because the fiscal 
year 2010 budget had not been submitted to the Congress at the time of 
the draft report, some of the report's findings are based on 
preliminary cost projections that existed at the time of our review 
rather than the official program of record. As such, the cost 
projections in this report may be different than the final fiscal year 
2010 program of record. We interviewed members of the joint estimating 
team to obtain a detailed understanding of the methodology, data, and 
approach used in developing their cost estimate and schedule risk 
analysis of the JSF program. We also interviewed JSF program officials 
to understand the program's cost estimate methodology, assumptions, and 
results and to obtain their response to the joint estimating team's 
analysis. Based on this analysis, we were able to identify significant 
differences in the cost estimating methodologies and assumptions used 
by the joint estimating team and the program office and to determine 
major risk drivers in the program. 

To assess the program's plans and risks in manufacturing and its 
capacity to accelerate production from fiscal years 2010 through 2015, 
we analyzed manufacturing cost and work performance data to assess 
progress against plans. We compared budgeted program labor hours to 
actual labor hours, identified growth trends, and noted differences 
between future labor requirements and current plans to release 
engineering staff. We reviewed data and briefings provided by the 
program and the Office of the Secretary of Defense (OSD) to assess 
supplier performance and ability to support accelerated production from 
fiscal years 2010 through 2015. We also determined reasons for 
manufacturing delays, discussed program and contractor plans to 
improve, and projected expected impacts on development and operational 
tests. We also reviewed the prime contractor's schedule estimates and 
compared them with relevant best practices[Footnote 14] to determine 
the extent to which they reflect key estimating practices that are 
fundamental to having a reliable schedule. In doing so, we interviewed 
cognizant program officials to discuss their use of best practices in 
creating the program's current schedule and interviewed officials from 
Naval Air Systems Command to understand their approach and to obtain 
results of their independent schedule risk analysis. 

To assess plans, progress, and risks in test activities, we examined 
program documents and interviewed DOD, program office, and contractor 
officials about current test plans and progress. To assess progress 
toward test plans, we compared the number of flight tests conducted as 
of October 2008 to those in the original test plan established in 2007. 
We also reviewed documents and interviewed prime contractor officials 
regarding flight testing, the integrated airborne test bed, and ground 
testing. To further assess the ground labs and test bed, we interviewed 
DOD and program officials and toured the testing labs and aircraft at 
the Lockheed Martin plant in Fort Worth, Texas. 

In performing our work, we obtained information and interviewed 
officials from the JSF Joint Program Office, Arlington, Virginia; 
Lockheed Martin Aeronautics, Fort Worth, Texas; Defense Contract 
Management Agency, Fort Worth, Texas; Defense Contract Management 
Agency, East Hartford, Connecticut; Naval Air Systems Command, Patuxent 
River, Maryland; Air Force Operational Test and Evaluation Center, 
Kirtland Air Force Base, New Mexico; Air Force Cost Analysis Agency, 
Arlington, Virginia; and OSD offices of the Under Secretary of Defense 
for Acquisition, Technology and Logistics, the Director of Program 
Analysis and Evaluation and its Cost Analysis Improvement Group, and 
the Director of Operational Test and Evaluation in Washington, D.C. 

We conducted this performance audit from June 2008 to March 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.

Appendix II: GAO Assessment of Prime Contractor Schedule Management 
Processes: 

Prime Contractor's Scheduling Management Processes Meet Many Best 
Practices, but Program Risks Are Not Entirely Visible: 

The success of any program depends in part on having a reliable 
schedule of when the program's set of work activities will occur, how 
long they will take, and how they are related to one another. As such, 
the schedule not only provides a road map for systematic execution of a 
program, but also provides the means by which to gauge progress, 
identify and address potential problems, and promote accountability. 

In general, best practices and related federal guidance call for a 
program schedule to identify, sequence, integrate, and resource all key 
activities to be performed, and to understand and proactively address 
activities that pose critical risks. More specifically, our research 
has identified nine practices associated with effective schedule 
estimating.[Footnote 15] These practices are (1) capturing all 
activities, (2) sequencing all activities, (3) assigning resources to 
all activities, (4) establishing the duration of all activities, (5) 
integrating schedule activities horizontally and vertically, (6) 
establishing the critical path for all activities, (7) identifying 
float[Footnote 16] between activities, (8) conducting a schedule risk 
analysis, and (9) updating the schedule using logic and durations to 
determine dates. 

Of these nine practices, the JSF program either met or partially met 
eight with only one not being met. The area that did not meet the 
practices related to performing a schedule risk analysis. Specifically, 
the JSF program has not conducted its own schedule risk analysis that 
would determine the level of confidence it has in meeting completion 
dates. Further, an assessment is also critical to identifying and 
apportioning reserves for contingencies. Since the JSF program has not 
conducted its own schedule risk analysis, it has limited insight into 
areas of risk and uncertainty in the schedule. Naval Air Systems 
Command officials did accomplish an independent schedule risk analysis 
that indicated that the program could slip more than 2 years based on 
the productivity risks associated with software development and 
assembly of the various airframes as well as the time needed to 
complete all flight testing. 

In addition to a schedule risk analysis not being performed, we found 
several other schedule management concerns that further reduce the 
visibility of manufacturing risks. First, the use of best scheduling 
practices at the subcontractor level is still being developed, 
potentially affecting the integration of subcontractor schedules into 
the integrated master schedule. Integrating prime and subcontractor 
schedules is critical to meeting program schedules and cost 
expectations. The prime contractor is working with subcontractors to 
increase their level of schedule maturity. Another area of concern is 
that out-of-station work made it difficult to identify specific span 
times for individual manufacturing tasks.[Footnote 17] As a result, the 
detailed information related to the manufacturing work was not visible 
in the master schedule. Furthermore, because of the program's enormous 
size and complexity, the schedule has been difficult to maintain, 
requiring manual validation processes to ensure its integrity and 
validity. Ongoing JSF schedule validity will be an area that needs 
careful attention as it represents a potential weak point in the 
overall implementation of the integrated master schedule. 

Despite this shortcoming, it is also important to recognize the 
significant progress that the JSF program team has made in the area of 
schedule management. Since the previous Defense Contract Management 
Agency schedule review, both the schedule and the processes to manage 
it have greatly improved. For example, the schedule can track and 
verify activities associated with over 600 projects. It also 
successfully captures and sequences key activities and establishes the 
critical path between key activities, allowing the program to examine 
the impacts of schedule delays and determine schedule flexibility. 

The Sheer Size and Complexity of the JSF Schedule Have Created Major 
Challenges to Ensuring Schedule Integrity and Validity: 

The JSF schedule is maintained in Microsoft Project and consists of 
over 600 individual projects. Because the size and complexity of the 
schedule is so immense, it has been difficult to maintain. As such, a 
number of manual validation processes are required to ensure its 
integrity and validity. To its credit, the contractor has developed 
custom processes and tools to help manage the program schedule. 
However, because of its enormous size and complexity, the JSF's ongoing 
schedule validity will be an area that needs careful attention as it 
represents a potential weak point in the overall implementation of the 
integrated master schedule. 

Because the schedule was so large, we reviewed a subset of it, focusing 
on the delivery of one airframe for each variant of the F-35 being 
produced (i.e., BF4, AF1, and AF3). This subset schedule covered a time 
span from August 2006 through September 2014, and we analyzed it 
against our best practices for effective schedule estimating. See table 
6 for the results of our analyses relative to each of the nine 
practices. 

Table 6: Prime Contractor Schedule Management System Compared to Best 
Practices: 

Criterion: Capturing all activities; 
Explanation: The schedule should reflect all activities (e.g., steps, 
events, outcomes, etc.) as defined in the program's work breakdown 
structure, to include activities to be performed by both the government 
and its contractors; 
Criterion met?[A]: Yes; 
GAO analysis: The program's schedule reflected both government and 
contractor activities, including activities related to designing, 
developing, testing, and manufacturing the three variants of the F-35. 

Criterion: Sequencing all activities; 
Explanation: The schedule should be planned so that it can meet program-
critical dates. To meet this objective, key activities need to be 
logically sequenced in the order that they are to be carried out. In 
particular, activities that must finish prior to the start of other 
activities (i.e., predecessor activities) as well as activities that 
cannot begin until other activities are completed (i.e., successor 
activities) should be identified. By doing so, interdependencies among 
activities that collectively lead to the accomplishment of events or 
milestones can be established and used as a basis for guiding work and 
measuring progress; 
Criterion met?[A]: Yes; 
GAO analysis: The schedule included the sequencing of key activities, 
meaning that it included both the predecessor and successor activities 
and thus established interdependencies among the activities that form 
the basis for guiding work and measuring progress. The schedule logic 
was validated by numerous metrics that were tracked on a monthly basis. 
For example, the contractor collected metrics that verified that logic 
was not maintained at summary-level tasks, activities had both a 
predecessor and successor relationship, and external links were valid. 
Additionally, the metrics tracked the use of hard constraints so if any 
were found, there were procedures to remove any constraints that 
override schedule logic. These detailed metrics provided assurance in 
the validity of the schedule. They also enabled the program to have 
confidence that the sequencing of activities was not being overwritten 
by an overuse of constraints. 

Criterion: Assigning resources to all activities; 
Explanation: The schedule should reflect what resources (i.e., labor, 
material, and overhead) are needed to do the work, whether all required 
resources will be available when they are needed, and whether any 
funding or time constraints exist; 
Criterion met?[A]: Partially; 
GAO analysis: The resources, labor, materials, and overhead were not 
loaded directly into the Microsoft Project schedules. Instead, the 
budgets were maintained in another system, which was integrated with 
both the schedule and the Manufacturing Resource Planning (MRP) system. 
While not technically assigned to individual activities, the resources 
were integrated into the management of the system through the work 
packages identified in the earned value system. The manufacturing 
activity resources were maintained in the MRP system and the schedule 
reflected the level of work accomplished in various production stations 
based on the status of the individual work cards. Program officials 
provided a data trace between the schedule, MRP system, and earned 
value system to demonstrate how the resources were integrated with the 
schedule. 

Criterion: Establishing the duration of all activities; 
Explanation: The schedule should realistically reflect how long each 
activity will take to execute. In determining the duration of each 
activity, the same rationale, data, and assumptions used for cost 
estimating should be used for schedule estimating. Further, these 
durations should be as short as possible and they should have specific 
start and end dates. Excessively long periods needed to execute an 
activity should prompt further decomposition of the activity so that 
shorter execution durations will result; 
Criterion met?[A]: Partially; 
GAO analysis: The schedule established the durations of key activities 
based on historical data from the contractor's experience, projected 
savings to be gained from implementing robust processes to maintain the 
flow of work on the manufacturing floor, and expected savings from 
investing up front in modeling and simulation. The program tracked the 
actual start, progress, and actual finish of activities in the 
schedule, allowing for collection of trending information. Progress 
metrics were tracked by the contractor in the status metric process and 
reported to the program, enabling tracking against the schedules; 
It was difficult, however, to see the specific span times for 
individual manufacturing tasks because work that did not finish in its 
designated station was carried forward and completed at a different 
station down the production line (this work was called out-of-station). 
As a result, the detailed information related to the manufacturing work 
was maintained in the MRP system, but was not visible within the 
schedule itself. Nonetheless, the contractor demonstrated the 
relationship between the specific work cards in the MRP system and how 
those data translated to the schedule. 

Criterion: Integrating schedule activities horizontally and vertically; 
Explanation: The schedule should be horizontally integrated, meaning 
that it should link the products and outcomes associated with already 
sequenced activities. These links are commonly referred to as handoffs 
and serve to verify that activities are arranged in the right order to 
achieve aggregated products or outcomes. The schedule should also be 
vertically integrated, meaning that traceability exists among varying 
levels of activities and supporting tasks and subtasks. Such mapping or 
alignment among levels enables different groups to work to the same 
master schedule; 
Criterion met?[A]: Yes; 
GAO analysis: The schedule was both horizontally and vertically 
integrated and there was a robust process in place to verify the 
traceability at each progress cycle. The contractor's project status 
sheet identified where activities were missing relationships, enabling 
a critical path to be derived by the tool's critical path analysis. 
Relationships were maintained across the 600+ individual projects and 
verified through periodic schedule health checks. The contractor 
provided report outputs and demonstrated the process it used to 
identify and validate that the links across projects were intact. 
Similarly, for vertical integration the contractor demonstrated how 
status was rolled up from the individual project files to the proper 
higher-level summary activities so the overall schedule reflected the 
proper dates and status; 
An area of concern was with the integration of the subcontractors' 
schedules into the integrated master schedule. The issue was not as 
much the integration of the data, but the use of scheduling best 
practices at the subcontractor level. The contractor was working with 
its subcontractors to increase the level of scheduling maturity. 
Moreover, given the massive size of the integrated master schedule and 
number of files being utilized to integrate it, this was an area that 
needed continual monitoring to verify compliance. 

Criterion: Establishing the critical path for all activities; 
Explanation: Using scheduling software the critical path--the longest 
duration path through the sequenced list of key activities--should be 
identified. The establishment of a program's critical path is necessary 
for examining the effects of any activity slipping along this path. 
Potential problems that may occur on or near the critical path should 
also be identified and reflected in the scheduling of the time for high-
risk activities; 
Criterion met?[A]: Yes; 
GAO analysis: The program's critical path was defined using scheduling 
software. Critical paths were defined by individual airframes and were 
also calculated at the total program level. The contractor provided 
output from the critical path analysis and demonstrated the process it 
used to produce the critical path. Given the large number of files and 
overall size of the integrated master schedule, it was not possible to 
validate the critical path through independent analysis; 
The contractor's metric process performed during each status cycle 
helped to maintain and validate the critical path produced by the tool. 
In the subset schedule we reviewed there were no hard constraints, that 
is, we found no "must start" or "must finish" on dates that could 
override the critical path analysis and cause invalid results. 

Criterion: Identifying float between activities; 
Explanation: The schedule should identify float--the time that a 
predecessor activity can slip before the delay affects successor 
activities--so that schedule flexibility can be determined. As a 
general rule, activities along the critical path typically have the 
least amount of float; 
Criterion met?[A]: Yes; 
GAO analysis: The contractor's overall schedule process enabled good 
visibility into the float between activities and demonstrated that 
float is actively managed. The metrics tracked by the contractor 
clearly identified where there were issues with the amount of float on 
an activity, including which tasks had negative float. The contractor 
had defined processes for tracing and understanding what was driving 
that float. In addition, the tracking and removal of hard constraints 
in the schedule enabled the tool to generate the float via the critical 
path analysis. 

Criterion: Conducting a schedule risk analysis; 
Explanation: A schedule risk analysis uses a good critical path method 
schedule and data about project schedule risks as well as Monte Carlo 
simulation techniques to predict the level of confidence in meeting a 
program's completion date, the amount of time contingency needed for a 
level of confidence, and the identification of high-priority risks. 
This analysis focuses not only on critical path activities but also on 
other schedule paths that may become critical. A schedule/cost risk 
assessment recognizes the interrelationship between schedule and cost 
and captures the risk that schedule durations and cost estimates may 
vary because of, among other things, limited data, optimistic 
estimating, technical challenges, and lack of qualified personnel. As a 
result, the baseline schedule should include a buffer or a reserve of 
extra time. Schedule reserve for contingencies should be calculated by 
performing a schedule risk analysis. As a general rule, the reserve 
should be held by the project manager and applied as needed to those 
activities that take longer than scheduled because of the identified 
risks. Reserves of time should not be apportioned in advance to any 
specific activity since the risks that will actually occur and the 
magnitude of their impact is not known in advance; 
Criterion met?[A]: No; 
GAO analysis: The contractor did not perform a schedule risk analysis 
that would have determined the level of confidence in meeting the 
program's completion date and identified reserves for contingencies 
because it did not have time to do this analysis. The contractor spent 
much of the past year rebaselining its schedule so it would be more 
realistic and meet best practices and said that it intended to do 
schedule risk analyses in the future; 
Naval Air Systems Command conducted an independent schedule risk 
analysis that indicated that the program could slip more than 2 years 
based on productivity risks associated with software development and 
assembly of the various airframes as well as the time needed to 
successfully complete all flight testing. Based on the command's 
results, the contractor does not have an adequate amount of schedule 
reserve to mitigate testing and production risks. This low reserve 
means that any delays in these areas would have an immediate impact to 
the overall project completion date. Moreover, there was concern from 
outside experts that savings gained from implementing robust 
manufacturing processes and relying more on modeling and simulation may 
not be achieved as they exceed anything done before. Both the 
contractor and the JSF Program Office disputed the findings of the 
command's schedule risk analysis primarily because the analysis was 
done without direct involvement of program officials. 

Criterion: Updating the schedule using logic and durations to determine 
the dates; 
Explanation: The schedule should use logic and durations in order to 
reflect realistic start and completion dates for program activities. 
The schedule should be continually monitored to determine when 
forecasted completion dates differ from the planned dates, which can be 
used to determine whether schedule variances will affect downstream 
work. Maintaining the integrity of the schedule logic is not only 
necessary to reflect true status, but is also required before 
conducting a schedule risk analysis. The schedule should avoid logic 
overrides and artificial constraint dates that are chosen to create a 
certain result on paper. To ensure that the schedule is properly 
updated, individuals trained in critical path method scheduling should 
be responsible for updating the schedule status; 
Criterion met?[A]: Yes; 
GAO analysis: The contractor demonstrated that it relies on logic and 
duration to determine the dates when it updates the status of its 
schedule. For example, the contractor showed us how it monitors the 
schedule on a weekly basis to ensure that start and completion dates 
are realistic and to identify where there are variances between planned 
and actual progress. The contractor also demonstrated how it verifies 
that all hard constraints have been removed so that the schedule 
depicts actual conditions. Moreover, the personnel responsible for 
maintaining the schedule demonstrated a strong understanding of 
critical path method scheduling, adding to our confidence that the 
schedule is being properly updated in accordance with best practices.

Mr. Michael Sullivan: 
Director, Acquisition and Sourcing Management: 
U.S. Government Accountability Office: 
441 G Street, N.W.: 
Washington, DC 20548: 

Dear Mr. Sullivan: 

This is the Department of Defense (DoD) response to the GAO draft 
report 09-303, "Joint Strike Fighter: DOD'S Proposal to Accelerate 
Procurement before Completing Development Increases the Government's 
Financial Risk" dated February 2, 2009, (GAO Code 120742). Detailed 
comments on the report recommendations are enclosed. 

The DoD partially concurs with recommendation one and concurs with 
recommendation two. The rationale for our position is included in the 
enclosure. 

We appreciate the opportunity to comment on the draft report. My point 
of contact for this effort is CAPT Gregg Sears, 703-695-3015,

Portfolio Systems Acquisition GAO Draft Report Dated FEBRUARY 2, 2009 
GAO-09-303 (GAO CODE 120742): 

"Joint Strike Fighter: Dod's Proposal To Accelerate Procurement Before 
Completing Development Increases The Government's Financial Risk"  

Department Of Defense: 

Comments To The GAO Recommendations: 

Recommendation 1: The GAO recommends that the Secretary of Defense 
direct that the Joint Strike Fighter program office report to the 
Congressional Defense Committees by October 1, 2009. 

DOD Response: Partially concur The Department agrees that a report to 
the Congressional Defense Committees explaining the Department's plan 
to transition from cost reimbursable contracts to fixed price contracts 
for Joint Strike Fighter (JSF) procurement would be beneficial to 
enhance Congressional oversight and confidence in the JSF program. 
However, the Department believes that the Under Secretary of Defense 
for Acquisition, Technology and Logistics (USD AT&L) should be 
responsible for the report, not the Joint Strike Fighter program. As 
the Milestone Decision Authority (MDA), USD (AT&L) is responsible for 
approval of the JSF Acquisition Strategy, including the contracting 
strategy, as well as approval of individual Low Rate Initial Production 
(LRIP) contract awards and the transition to Full Rate Production 
(FRP). The JSF Acquisition Strategy, utilizing cost reimbursable 
contracts that contain cost and performance incentives for LRIP, has 
been approved by the Department and involved a review of the associated 
risks, benefits, and options. The USD AT&L, on behalf of the Secretary 
will provide a report to the Congressional Defense Committees by 
October 1, 2009, that addresses the requirements in the recommendation. 

The Department would also like to state that since the FY 2010 
President's budget had not yet been submitted to Congress at the time 
of the draft report, the fact is that much of the data that the GAO 
used as the basis of their report and to support its recommendation was 
pre- decisional. The JSF program of record remained as submitted in the 
FY 2009 President's Budget, adjusted by the FY 2009 Defense 
Appropriations Bill. The Department believes that the GAO's use of pre-
decisional budget information to support its findings is largely 
conjectural, and likely to create confusion if the final FY 2010 
program of record is different than what the GAO reported. 

The JSF program does have substantial concurrency of development, test 
and production built into the JSF schedule, a fact that the Department 
acknowledges and has approved. That concurrency is designed to provide 
the warfighters with a 5th generation strike fighter to replace aging 
legacy aircraft as quickly as possible, as efficiently as possible, and 
as affordably as possible. The Department acknowledges the risks, and 
benefits, of the concurrency required to acquire and deliver this 
critical capability. The Department also believes that the program is 
well managed, with the proper amount of oversight, and well positioned 
to succeed in accomplishing this mission. 

Recommendation 2: The GAO recommends that the Secretary of Defense 
direct that the Joint Program Office ensure the prime contractor 
performs periodic schedule risk analyses for the Joint Strike Fighter 
(JSF) program to provide better insight into Management Reserve, 
production efficiencies, and schedule completion to allow for 
corrections as early as possible. 

DOD Response: Concur The Department will direct that the contractor 
perform periodic schedule risk analysis. The Department will coordinate 
with the JSF Program Office and determine an optimum schedule for the 
contractor to meet that will provide appropriate insight into JSF cost 
and schedule to influence key program milestones and decision making.

[8] The difference in the two estimates is actually more than $5 
billion. The joint estimating team's numbers only go through fiscal 
year 2015, but they are expecting development to take at least 1 more 
year beyond then. Program data presented to the Joint Chiefs suggest 
that an additional year for development flight testing and other 
government and contractor expenses could cost about $700 million.

as a product moves from workstation to workstation and on to final 
assembly. Out-of-station work, sometimes referred to as traveled work, 
refers to completing unfinished work on major components, for example, 
the wings, after they have left the wing workstation and moved down the 
production line to another station, such as mate and final assembly.

when a company can produce a product within cost, schedule, and quality 
targets. A best practice is to ensure that all key manufacturing 
processes are repeatable, sustainable, and capable of consistently 
producing parts within the product's quality tolerances and standards.

[16] Float is the amount of time an activity can slip before affecting 
the critical path. 

[17] It was difficult to see specific span times for individual 
manufacturing tasks because work that did not finish in its designated 
station was carried forward and completed at a different station down 
the production line. This work was called out-of-station.
