Anigrand Craftswork - 1/72 McDonnell-Douglas KC-10A Extender.
During the Vietnam War and Arab-Israeli War, the U.S.A.F. C-141 and C-5 were forced to carry a fraction of their maximum payload on direct flights from the continental United States to Asia and Israel. The strategic airlift operations demonstrated the necessity of adequate air-refueling capability. The U.S. Department of Defense concluded that a more advanced tanker was needed. The 'Advance Tanker Cargo Aircraft' program was launched in 1975, four aircraft were evaluated: the Boeing 747, the McDonnell-Douglas DC-10 Douglas DC-10 , the Lockheed L-1011 Tristar and C-5 Galaxy. The U.S.Air Force selected McDonnell-Douglas 's DC-10 in 1977. The design for the KC-10 involved only modifications from the DC-10-30CF design. The major changes were the addition of a boom control station in the rear of the fuselage and extra fuel tanks below the main deck. The KC-10 first flew in July 1980. The first aerial refueling occurred during testing in October 1980, with the receiver aircraft a C-5 Galaxy. The first KC-10 was delivered to the U.S.A.F. in 1981. The 60th and last was formally handed over in 1988.
