F-35 Joint Strike Fighter (JSF) Program

The largest procurement program in the Department of Defense (DOD), the F-35 Joint Strike Fighter (JSF), also called the Lightning II, is a new aircraft being procured in different versions for the United States Air Force, Marine Corps, and Navy. Current DOD plans call for acquiring a total of 2,456 JSFs. Hundreds of additional F-35s are expected to be purchased by several U.S. allies, eight of which are cost-sharing partners in the program.

The F-35 promises significant advances in military capability. Like many high-technology programs before it, reaching that capability has put the program above its original budget and behind the planned schedule.

The Administration’s proposed FY2012 defense budget requested about $6.6 billion in procurement funding for the F-35 Joint Strike Fighter (JSF) program. This would fund the procurement of 19 F-35As for the Air Force, 6 F-35Bs for the Marine Corps, and 7 F-35Cs for the Navy.

The Administration’s proposed FY2012 defense budget also requested no funds for the F-35 alternate engine program, which was intended to develop the General Electric/Rolls-Royce F136 engine as an alternative to the Pratt and Whitney F135 engine that currently powers the F-35. The F-35 alternate engine program was a major item of debate on the FY2011 defense budget. 

FY2012 defense authorization act: The report on the House-passed version of the FY2011 defense authorization bill included language limiting expenditure of funds for performance improvements to the F-35 propulsion system unless development and production of such propulsion system is done competitively. Other language required the Secretary of Defense to preserve and store government-owned property acquired under the F136 propulsion system development contract and allows the contractor to conduct research, development, test, and evaluation of the F136 engine at the contractor’s expense. The Senate Armed Services Committee report required that the fifth F-35 low-rate initial production contract lot be a fixed price contract, and that the contractor assume full responsibility for costs under the contract above the target cost specified in the contract. The Senate report also required DOD to implement the requirements of the Weapon Systems Acquisition Reform Act of 2009 in the F-35 program. 

FY2012 DOD appropriations bill: The House Appropriations Committee funded 19 F-35As, 6 F-35Bs, and 7 F-35Cs, as requested, while cutting $55 million from F-35C and $75 million from F-35 research and development. The Senate Appropriations Committee funded 17 F-35As, 6 F- 35Bs, and 6 F-35Cs. With cuts to R&D and advance procurement, the SAC mark funded $695 million less than the Administration request.
