Thirteenth Air Force along with Fifth Air Force in Australia and Seventh Air Force in Hawaii were assigned to the newly created United States Far East Air Forces (FEAF) on 3 August 1944. FEAF was subordinate to the U.S. Army Forces Far East and served as the headquarters of Allied Air Forces Southwest Pacific Area. By 1945, three numbered air forces—5th, 7th and 13th—were supporting operations in the Pacific. FEAF was the functional equivalent in the Pacific of the United States Strategic Air Forces (USSTAF) in the European Theater of Operations.
