1973. The 78th Troop Carrier Squadron was subsequently inactivated and replaced by the 47th Tactical Fighter Squadron. During the late 1980s, the 917 TFG group was upgraded to wing status and renamed the 917th Tactical Fighter Wing (917 TFW). Due to air force restructuring in June 1992, Tactical Air Command was combined with all elements of the Strategic Air Command (except KC-135 and KC-10 aircraft) to form the new Air Combat Command (ACC). The 917th Tactical Fighter Wing joined Air Combat Command and "Tactical" was dropped from its name. On 1 October 1993, the 917th Fighter Wing (917 FW) saw important changes once again. The 46th Fighter Training Squadron was inactivated when the active-duty Air Force took control of all fighter replacement training. On this same day, the 917th became the first unit in Air Force Reserve history to acquire a strategic mission: B-52Hs were added to the wing make-up and the 93rd Bomb Squadron was activated. Now a composite wing, the 917th dropped "Fighter" from its name and became the 917th Wing (917 WG). In its 2005 BRAC Recommendations, DoD recommended to realign Eielson Air Force Base, Alaska. Some of the 354th Fighter Wing's assigned A-10 aircraft (located at Eielson AFB) would be distributed to the 917th Wing Barksdale Air Force Base (three aircraft). This recommendation was made because, although a base with high military value, Eielson was an expensive base to maintain. In another Recommendation, DoD recommended to realign Air Force Reserve fighter assets at Naval Air Station Joint Reserve Base New Orleans, LA. It would distribute six of the 926th Fighter Wing's A-10 aircraft to the 917th Wing. On 20 September 2009, the airport was used as a refuelling stop for the Space Shuttle Discovery's return flight to the Kennedy Space Center that was being piggybacked from Naval Air Station Joint Reserve Base Fort Worth. The Shuttle Carrier Aircraft and Space Shuttle Discovery remained at Barksdale over night. Bossier Base Bossier Base, now called The East Reservation due to its location east of the runway, was formerly a Defense Atomic Support Agency (DASA) Q clearance maintenance and WSA during the Cold War. It was similar to Sandia Base's Manzano. Once entirely independent of the USAF and Barksdale AFB, it has been merged with the main base.
