The 406th Air Expeditionary Wing (406 AEW) is a provisional unit assigned to the United States Air Forces in Europe. The wing was reactivated in early 2003 as a provisional wing to be used as part of Operation Iraqi Freedom (OIF), based in Turkey. When Turkey refused to allow its territory to be used as part of the March 2003 invasion of Iraq, It seems likely the 406 AEW was inactivated shortly afterward. Sometime afterward, it was possibly reactivated at RAFO Thumrait, Oman, possibly with KC-135 tankers. Possibly later moved to Camp Bastion, Afghanistan. Its current status is undetermined.
