Programme du budget de la défense US 2010

[quote]The Administration has decided not to fund the Joint Strike Fighter (JSF) Alternative Engine Program
(AEP), because it is no longer needed as a hedge against the failure of the main Joint Strike Fighter engine
program. The Department of Defense (DOD) proposed cancelling the JSF AEP in the President's 2007 Budget
because development of the main engine was progressing well and analysis indicated that savings from
competition would not be offset by high upfront costs. DOD did not request funding for the program in the
2008 and 2009 Budgets. However, the Congress has rejected the proposed cancellations and has added
funding each year since 2007 to sustain the AEP development.


Because DOD wanted to reduce technical risk in the development of the JSF engine, the Department has
had two contractors developing separate JSF engines. However, in 2007, DOD proposed to cancel the contract
for the second (alternate) engine because the main engine program was progressing well, making a second
engine program unnecessary. Moreover, financial benefits, such as savings from competition, have been
assessed to be small, if they exist at all, because of the high cost of developing, producing and maintaining
a second engine. The reasons for canceling the AEP in 2007 remain valid today. Studies by both the
Government Accountability Office and Congressional Budget Office have questioned the affordability of the
current defense program, particularly the high cost of modernizing tactical aviation.1,2 Canceling the AEP
will result in estimated near-term savings of over a billion dollars.[/quote]
