Unlike the numbered air forces of the United States Army Air Forces (USAAF), the Tactical Air Forces did not include strategic bombing/heavy bomber capability. The USAAF situation changed in late 1943 when the 12th Air Force transferred its heavy bombers to the newly formed 15th Air Force. Later, when the Allied air forces in the MTO were reorganized into the Mediterranean Allied Air Forces (MAAF), the US 12th Air Force and the RAF Desert Air Force became part of the Mediterranean Allied Tactical Air Force and the US 15th Air Force and No. 205 Group RAF became part of the Mediterranean Allied Strategic Air Force. A Mediterranean Allied Coastal Air Force was also part of MAAF.
