Acronym for the United States Air Force, the aerial warfare branch of the U.S. military established as an independent service in 1947.
Acronym formed from the initial letters of 'United States Air Force.' Created when the Air Force became an independent military branch, separate from the Army Air Forces, reflecting the strategic importance of air power in modern warfare.
The USAF is unique among world air forces for being born in the atomic age - it was created partly to manage America's nuclear arsenal, making it the first military service designed around weapons of mass destruction. Its motto 'Aim High, Fly-Fight-Win' reflects both literal and metaphorical elevation.
