The AAF in Northwest Africa focuses on the Allied assault on Northwest Africa and the battle for Tunisia—the critical second front that secured the Mediterranean and increased the enemy's vulnerability to a massive invasion from Britain. From this experience of the Twelfth Air Force and its British counterparts in 1942–43 evolved a spirit of Anglo-American cooperation and important aspects of air doctrine still relevant to today's Air Force.
