Lockheed Martin Corp. has been awarded a $160 million contract from Japan's Mitsubishi Heavy Industries to produce components for eight more F-2 Japanese support fighters. Bethesda, Maryland-based Lockheed is already producing aft fuselages, wing leading-edge flaps and stores management systems and other components for the first 57 of Japan's new F-2 fighters under six earlier contracts. This seventh contract brings the total to 65 aircraft, the company said. Japan chose the Lockheed F-16 as the basis for the design of its new support fighter in 1987. MHI delivered the first production aircraft to the Japan Defense Agency in September 2000, and delivered 36 F-2s by the end of March 2003. Lockheed said it would begin delivering F-2 components under the new contract in March
