The Northwest African Strategic Air Force (NASAF) was a sub-command of the Northwest African Air Forces (NAAF) which itself was a sub-command of the Mediterranean Air Command (MAC). These new Allied air force organizations were created at the Casablanca Conference in January 1943 to promote cooperation between the British Royal Air Force (RAF), the American United States Army Air Forces (USAAF), and their respective ground and naval forces in the North African and Mediterranean Theater of Operations (MTO).
Effective February 18, 1943, the NASAF and other MAC commands existed until December 10, 1943 when MAC was disbanded and the Mediterranean Allied Air Forces (MAAF) were established. Major General Jimmy Doolittle was the commander of NASAF.[1] However, during at least one critical period of the Tunisia Campaign at the end of February, 1943, General Carl Spaatz, the commander of NAAF, placed most of the strategic bombers at the disposal of Air Marshal Sir Arthur Coningham, commander of the Northwest African Tactical Air Force.[2]
