The United States Army Air Corps (USAAC) was the military aviation arm of the United States of America between 1926 and 1941. The statutory administrative forerunner of the United States Air Force, it was renamed from the earlier United States Army Air Service on 2 July 1926 and part of the larger United States Army. The Air Corps was the immediate predecessor of the United States Army Air Forces (USAAF), established on 20 June 1941. Although discontinued as an administrative echelon during World War II, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force.
