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).
