EDWARDS AIR FORCE BASE, Calif. AFPN (Feb. 23, 1999) -- Raptor 4002 passed its 300th flight-hour mark -- the first F-22 to do so -- during a Feb. 18 sortie from the Air Force's Flight Test Center here. The F-22 fleet is expected to grow in the coming weeks, as Raptor 4003 makes it maiden flight from Lockheed Martin's facility in Marietta, Ga., before joining the F-22 Combined Test Force here later this year.(Article Courtesy USAF Press Release)
