The Northwest African Coastal Air Force (NACAF) was a specialized functional command of the combined Northwest African Air Forces. The Mediterranean Air Command (MAC) oversaw the combined air forces until superseded by the MAAF.
The NACAF had responsibility for air defense of North Africa, sea/air reconnaissance, antisubmarine air operations, air protection of Allied shipping, and air interdiction of enemy shipping. The components of NACAF at the time of the Allied invasion of Sicily (Operation Husky) on July 10, 1943 are illustrated below.[1][2]
