High Quality Content by WIKIPEDIA articles! There were aircraft losses during the Vietnam War. Hundreds of U.S. fixed-wing aircraft were lost to ground fire of antiaircraft artillery (AAA), surface-to-air missiles (SAMs), and fighter interceptors (MiG)s. The great majority of U.S. combat losses in all areas of Southeast Asia were to AAA. The Royal Australian Air Force also flew combat and airlift missions in South Vietnam, as did the Republic of Vietnam. Among fixed-wing aircraft, more F-4 Phantoms were lost than any other type in service with any nation.
