One of the original four numbered air forces formed in the United States in 1940, the First Air Force provided air defense and conducted combat training for personnel of newly formed units. Following World War II this air force was involved in air defense and reserve training and concentrated entirely upon air defense in the latter 1960s and again after 1985.
