The91st Attack Squadron is aUnited States Air Force Reserve unit based atCreech Air Force Base, Nevada, where it is anassociate unit of the432nd Wing operating General Atomics MQ-9 Reaper and RQ-170 Sentinel unmanned aerial vehicles (UAVs).

Previously it was assigned to81st Tactical Fighter Wing,USAFE, stationed atRAF Woodbridge,England, flyingA-10A Thunderbolt II, until inactivated on 14 August 1992.

Thesquadron's mission is to maintain combat-ready reservists to train and equip the combat air forces to conduct integrated and expeditionary combat operations, as well as conduct training operations in the MQ-1 Predator and MQ-9 Reaper Remotely Piloted Aircraft.^[2]

The squadron was activated in early 1942 underIII Fighter Command in North Carolina. Initially trained withP-39 Airacobras, re-equipped withP-38 Lightnings.

Moved overseas, October 1942 – February 1943, the ground echelon arriving inFrench Morocco with the force that invaded North Africa on 8 November, and the air echelon, which had trained for a time in England, arriving in North Africa between late December 1942 and early February 1943.

Began combat withTwelfth Air Force in January 1943. Supported ground operations during the Allied drive against Axis forces inTunisia. Patrolled the coast of North Africa and protected Allied shipping in theMediterranean Sea, April–July 1943. Provided cover for the convoys that landed troops onPantelleria on 11 June and on Sicily on 10 July 1943. Supported the landings atAnzio on 22 January 1944 and flew patrols in that area for a short time.

Reassigned to theChina-Burma-India Theater (CBI) and moved toIndia, February–March 1944. Initially performed training with P-40 and P-47 aircraft. Moved to China in May and became part ofFourteenth Air Force. Continued training and on occasion flew patrol and escort missions before returning to full-time combat duty in January 1945. Attacked enemy airfields and installations, flew escort missions, and aided the operations of Chinese ground forces by attacking troop concentrations, ammunition dumps, lines of communications, and other targets to hinder Japanese efforts to move men and materiel to the front.

Inactivated in China on 27 December 1945.

Reactivated atWheeler Field,Hawaii Territory in late 1946. Equipped withP-51 Mustangs and performed air defense of theHawaiian Islands until 1949. Was reassigned to theTactical Air CommandNinth Air Force, being stationed in New Mexico. Re-equipped withF-80 Shooting Star jet aircraft, trained as a tactical fighter squadron. Upgraded toF-86 Sabres in 1950.

Reassigned toAir Defense Command, becoming part of theWestern Air Defense Force, being moved toMoses Lake AFB, Washington. In Washington the squadron's mission was the air defense of eastern Washington, including theGrand Coulee Dam and theHanford Nuclear Reservation.

Ordered to theUnited Kingdom in 1951, mission to assist theRoyal Air Force in the Air Defense ofEast Anglia, being assigned to the newly refurbishedRAF Bentwaters. Also operated from a dispersed station,RAF Shepherds Grove about forty miles apart.

The squadron was one of the first Sabre Jet unit to be based in Europe, and the first to form an integral part of the peacetime air defense ofGreat Britain. In this role, the squadron came under the operational control of theRAF Fighter CommandNo. 11 Group during the actual defense of the United Kingdom, and for combined operational training. Under USAFE, the squadron came under the control ofThird Air Force which coordinated its activities with the RAF.

In October 1954 the mission of the squadron changed from fighter-interceptor to fighter-bomber operations, carrying both conventional and nuclear weapons. The squadron was charged with tactical operations in support of USAFE and NATO, with air defense as a secondary mission. To reflect this change, the unit traded in its F-86s for theF-84F Thunderstreak.

Beginning in the fall of 1958, the squadron was reequipped with the McDonnellF-101 Voodoo. The F-101 was configured as a fighter bomber, intended to carry a single nuclear weapon for use against battlefield targets such as airfields. The Voodos were equipped with Low Angle Drogued Delivery (LADD) and Low Altitude Bombing System (LABS) equipment for its primary mission of delivering nuclear weapons at extremely low altitudes. Pilots were trained for one-way missions into Soviet territory to increase effective range at some cost in negating pilot recovery.

In November 1965, the squadron received McDonnellF-4 Phantom II to replace the Voodoos. Initially receiving the F-4C this was later upgraded to the more capable F-4D during late 1972 and 1973. Began conversion to the RepublicA-10 Thunderbolt II in June 1979. The A-10 being a single-seat, twin-engine jet aircraft designed to provide close air support (CAS) of ground forces by attacking tanks, armored vehicles, and other ground targets. With the A-10, the squadron's mission changed to close air support and battlefield air interdiction in support of NATO ground forces.

With the end of theCold War in 1991, the USAF presence at Woodbridge and its sister base Bentwaters was gradually phased down. It was announced that the base would be closed and the squadron would be inactivated. Squadron was inactivated on 14 August 1992.

In 2013 the squadron was redesignated the91st Attack Squadron and reactivated atCreech Air Force Base, Nevada, where it is anassociate of the432d Wing.^[3]
