The 3973d Strategic Wing (3973d SW) is an inactive United States Air Force unit, discontinued at Moron Air Base, Spain in 1966. It was established in 1957 to support forward deployed elements of Strategic Air Command (SAC) (REFLEX) and added support of Boeing B-52 Stratofortress CHROME DOME missions, which continued after REFLEX operations ended. It was discontinued when its parent Sixteenth Air Force was transferred to United States Air Forces Europe (USAFE) after the CHROME DOME mission ended in Spain. History. The 3973d SW was a support element for the SAC originally for SAC Boeing B-47 Stratojet  wing and support elements deployed to Moron AB from United States bases (REFLEX) and later CHROME DOME operations between 1 June 1957 and 15 April 1966. When activated as the 3973d Air Base Squadron, it assumed the resources (Manpower, Equipment, Weapons, & Facilities) of the 7605th Air Base Squadron, a USAFE unit that had opened Moron. Throughout its existence it was controlled by SAC at Moron AB. The wing originated as the 3973d Air Base Squadron on 1 January 1957, replacing the 7605th Air Base Squadron of United States Air Forces Europe, which had opened Moron AB for United States Air  Force use. The wing trained and equipped personnel at Moron as well as supported CHROME DOME operations with Boeing KC-135 Stratotanker refueling B-52 Stratofortress aircraft. On 4 February 1965 REFLEX operations for Boeing B-47 Stratojet aircraft ended and the wing focused on other missions. CHROME DOME operations terminated on 23 January 1966 at the request of the Spanish government, following the crash of a B-52 near Palomares B-58 Hustler aircraft deployed from the 43d Bombardment Wing at Carswell AFB, Texas arrived at Moron 22 July 1964 for ALARM BELL operational training, remaining on station until September. The wing inactivated on  15 April 1966 when Moron AB transferred from SAC to United States Air Forces in Europe. The unit was replaced by the 7473d Combat Support Group under USAFE. SAC retained a tanker presence at Moron, but its mission was refueling USAFE fighter aircraft.
