DOD is expected to develop, procure, and maintain 2,443 aircraft at a cost of more than $950 billion. DOD plans for the JSF to replace or complement several types of aircraft in the Air Force, Navy, and Marine Corps. Given the program's cost and importance, it is critical that decisions are made within this program to maximize its benefit to the nation. This testimony highlights a number of those decisions and impacts. It (1) discusses emerging risks to the overall program, and (2) updates information for GAO's cost analysis of last year regarding sole-source and competitive scenarios for acquisition and sustainment of the JSF engine. Information on the overall program is from our mandated annual report, also issued today. GAO tracked annual cost and schedule changes, reasons for changes, decisions affecting development, and compared DOD cost estimating methodologies to best practices. For the two engines, GAO updated cost data from last year's testimony and made new projections. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-08-569T/html/GAOREPORTS-GAO-08-569T.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-08-569T/pdf/GAOREPORTS-GAO-08-569T.pdf GAO-08-569T https://www.govinfo.gov/app/details/GAOREPORTS-GAO-08-569T Testimony GAO-08-569T; Joint Strike Fighter: Impact of Recent Decisions on Program Risks; Aircraft Cost analysis Cost overruns Defense cost control Defense procurement Fighter aircraft Financial management Military aircraft Military research and development Operational testing Performance measures Program evaluation Program management Research and development costs Risk assessment Risk management Schedule slippages Cost estimates Program goals or objectives Joint Strike Fighter Public Law 108-375
