Summary:
The Defense Department's F-35 Lightning II Joint Strike Fighter (JSF) is one of three aircraft modernization programs in tactical aviation, the others being the Air Force F-22A fighter and the Navy F/A-18E/F fighter/attack plane. In November 1996, the Defense Department selected two major aerospace companies, Boeing and Lockheed Martin, to demonstrate competing designs for the JSF, a joint-service and multi-role fighter/attack plane. Lockheed Martin won this competition and was selected to develop and produce the JSF, a family of aircraft including conventional take-off and landing (CTOL), carrier-capable (CV), and short take-off vertical landing (STOVL) versions for the U.S. Air Force, Navy, and Marine Corps, the United Kingdom, as well as other allied services. Originally designated the Joint Advanced Strike Technology (JAST) program, the JSF program has attracted considerable attention in Congress because of concerns about its cost, effects on the defense industrial base, and implications for U.S. national security in the 21st century. The JAST/JSF program is designed to address the high cost of tactical aviation, the need to deploy fewer types of aircraft to reduce acquisition and operating costs, and projections of future threat scenarios and enemy capabilities. The program's rationale and primary emphasis is joint-service development of a next-generation multi-role strike aircraft that can be produced in affordable variants to meet different operational requirements. Developing an affordable tri-service family of aircraft with different (but similar) combat missions poses major technological challenges. If the JSF is to have joint-service support, the program must yield affordable aircraft that can meet such divergent needs as those of the U.S. Air Force for a successor to its low-cost F-16 and A-10 fighter/attack planes, those of the U.S. Marine Corps and the UK Royal Air Force and Navy for a successor to their Harrier STOVL aircraft, and the U.S. Navy's need for a successor to older F/A-18s and a complement to its F/A-18E/F fighter/attack planes. This report discusses the background, status, and current issues of the JSF program. Additional information and analysis can be found in CRS Report RL33543, Tactical Aircraft Modernization: Issues for Congress, which also discusses the Air Force F-22A, the Navy F/A-18EF, and the Marine Corps V-22. The JSF program is also addressed in CRS Report RL33390, Proposed Termination of Joint Strike Fighter (JSF) F136 Alternate Engine; CRS Report RS21488, NavyMarine Corps Tactical Air Integration Plan: Background and Issues for Congress; and CRS Report RL31360, Joint Strike Fighter (JSF): Potential National Security Questions Pertaining to a Single Production Line. This report will be updated as events warrant.
