The United States Air Force's 40th Air Expeditionary Wing (40 AEW) was an Air expeditionary unit located at Diego Garcia, in the Indian Ocean, from 2002 to c. 2006. The 40 AEW's mission was to support combat forces in Afghanistan and other combat areas supporting Operation Enduring Freedom. Operations began in October 2001.
Its predecessor unit, the United States Army Air Forces 40th Bombardment Group (40th BG) was part of Twentieth Air Force during World War II. The unit served primarily in the Pacific Ocean theater and China Burma India Theater of World War II. The 40th Bomb Group's aircraft engaged in very heavy bombardment B-29 Superfortress operations against Japan. Its aircraft were identified by Triangle "S".
The 40th Bombardment Group was one of the original ten USAAF bombardment groups assigned to Strategic Air Command on 21 March 1946; however, it was inactivated due to budget constraints on 1 August 1946. The unit was reactivated and elevated to Wing status in 1952 as a SAC B-47 Stratojet organization until the phaseout of the aircraft in 1964. Reactivated as a USAFE wing to be the host unit at Aviano Air Base, Italy in 1966 to provide support to Tactical Air Command deployed rotational elements until 1992.
