The F-35 Joint Strike Fighter (JSF) program is the DoD's most costly acquisition, seeking to simultaneously develop, produce, and field three aircraft variants for the Air Force, Navy, Marine Corps, and eight international partners. The total expected U.S. investment is now more than $300 billion to develop and procure 2,456 aircraft over the next 25 years. A report in March 2009 discussed increased dev¿t. costs and schedule estimates, plans to accelerate procurement, manufacturing performance and delays, and dev¿t. test strategy. This testimony discusses: (1) current JSF cost and schedule estimates; (2) engine dev¿t.; (3) manufacturing performance; (4) contracting issues for procurement of aircraft; (5) and test plans.

Joint Strike Fighter: Strong Risk Management Essential as Program Enters Most Challenging Phase

The F-35 Lightning II, also known as the Joint Strike Fighter (JSF), is the Department of Defense's most costly and ambitious aircraft acquisition, seeking to simultaneously develop and field three aircraft variants for the Air Force, Navy, Marine Corps, and eight international partners. The JSF is critical for recapitalizing tactical air forces and will require a long-term commitment to very large annual funding outlays. The current estimated investment is $323 billion to develop and procure 2,457 aircraft. This report discusses: (1) program cost, schedule, and performance; (2) manufacturing results; and (3) test plans and progress. The report's work includes interviews, cost data, test plans, production measures, and analyses by defense and contractor officials. Illus.
