The Allied Expeditionary Air Force (AEAF), also known as the Allied Armies’ Expeditionary Air Force (AAEAF), was the expeditionary warfare component of the Supreme Headquarters Allied Expeditionary Force (SHAEF) which controlled the tactical air power of the Allied forces during Operation Overlord during World War II in 1944. AEAF was dissolved after Leigh-Mallory was reassigned to command RAF forces in the Far East, later being killed in an air crash.
