Sixth Air Force was redesignated from the Caribbean Air Force in February 1942. Its primary function was conducting anti-submarine warfare over the Caribbean during World War II. It was redesignated Caribbean Air Command on 31 July 1946.
The direct precursor to the U.S. AirForce, the USAAF formally existed between 1941 and 1947.
Renamed the U.S. Army AirForces (USAAF) and considered a separate arm of the Army, the new USAAF had an equal "voice" with the Army and Navy.
The AirForces and Divisions were divided into a total of 91 Wings, called Bombardment, Tactical Reconnaissance, Training or Composite depending on whether their primary intended role was strategic bombing, pursuit, air support etc..
