United States Army Air Corps

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.

The Air Corps was renamed by the United States Congress largely as a compromise between the advocates of a separate air arm and those of the traditionalist Army high command who viewed the aviation arm as an auxiliary branch to support the ground forces. Although its members worked to promote the concept of air power and an autonomous air force between the years between the world wars, its primary purpose by Army policy remained support of ground forces rather than independent operations.
