During the Vietnam War, thousands of U.S. aircraft were lost to 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. Among fixedwing aircraft, more F-4 Phantoms were lost than any other type in service with any nation. In total, the United States military lost in Vietnam almost 10,000 aircraft and helicopters.
