The 931st ARW is an associate unit to the active-duty 22d Air Refueling Wing and currently has about 485 personnel. The host unit and the 931st ARW share responsibilities for maintenance, with flying operations conducted by both units, using the inventory of 48 KC-135R Stratotankers.
The group consists of the following units:18th Air Refueling Squadron
931st Aircraft Maintenance Squadron
931st Maintenance Squadron
931st Civil Engineer Squadron
931st Operations Support Squadron
931st Force Support Squadron
931st Security Forces Squadron
931st Aerospace Medicine Squadron
931st Maintenance Operations Flight
After May 1959, the reserve flying force consisted of 45 troop carrier squadrons assigned to 15 troop carrier wings. The squadrons were not all located with their parent wings, but were spread over thirty-five Air Force, Navy and civilian airfields under what was called the Detached Squadron Concept. The concept offered several advantages. Communities were more likely to accept the smaller squadrons than the large wings and the location of separate squadrons in smaller population centers would facilitate recruiting and manning. However, under this concept, all support organizations were located with the wing headquarters. Although this was not a problem when the entire wing was called to active service, mobilizing a single flying squadron and elements to support it proved difficult. This weakness was demonstrated in the partial mobilization of reserve units during the Berlin Crisis of 1961. To resolve this, at the start of 1962, Continental Air Command, (ConAC) determined to reorganize its reserve wings by establishing groups with support elements for each of its troop carrier squadrons. This reorganization would facilitate mobilization of elements of wings in various combinations when needed.
As a result, the 931st Troop Carrier Group was activated at Atterbury Air Force Base, Indiana on 11 February 1963 as the headquarters for the 72d Troop Carrier Squadron, which had been stationed there since February 1953. Along with group headquarters, a Combat Support Squadron, Materiel Squadron and a Tactical Infirmary were organized to support the 72d.
If mobilized, the group was gained by Tactical Air Command (TAC), which was also responsible for its training. Its mission was to organize, recruit and train Air Force reservists with Fairchild C-119 Flying Boxcars in the tactical airlift of airborne forces, their equipment and supplies and delivery of these forces and materials by airdrop, landing or cargo extraction systems.
The group was one of three C-119 groups assigned to the 434th Troop Carrier Wing in 1963, the others being the 930th Troop Carrier Group, also at Atterbury and the 932d Troop Carrier Group at Scott Air Force Base, Illinois.
The 931st performed routine reserve airlift operations until July 1969 when the Flying Boxcars were retired, and the unit was redesignated as a Tactical Air Support unit. The 72d was became the 72d Tactical Air Support Squadron and was re-equipped with Cessna U-3 Blue Canoe and Cessna O-2 Skymaster observation and close air support aircraft.
On 31 December 1969, in connection with the closing of Bakalar, the group and its squadron moved to Grissom Air Force Base, Indiana. First reassigned to the 403d Composite Wing on 1 June 1970 and then on 15 January 1971 to the 434th Special Operations Wing, on 1 March 1971, group and squadron converted to Cessna A-37B Dragonfly counter-insurgency aircraft being returned from South Vietnam. The A-37s were primarily an export aircraft used for foreign military sales and the unit trained personnel from other Air Force Reserve squadrons and Latin American Air Forces in the use of the aircraft.
The 72d was inactivated on 1 October 1973 and replaced by the 46th Tactical Fighter Squadron in a reorganization. The 46th was assigned directly to the 434th Tactical Fighter Wing and the 931st was inactivated on 1 July 1975.
In May 1977 the group became a Strategic Air Command (SAC) Boeing KC-135 Stratotanker air refueling unit, and activated at Grissom as part of the 452d Air Refueling Wing. The 931st was the third Air Force Reserve unit formed to provide air refueling support for SAC.
On 1 October 1978, the "Flying Hoosiers" achieved operational status 72 days ahead of schedule. That was the shortest time period ever recorded for an air refueling unit from activation to combat readiness. In the ensuing years, the 931st established more records of achievement including the Carl Spaatz Memorial Trophy, the Rousher Memorial Trophy for two consecutive years, the Golden Tanker Trophy and the Air Force Outstanding Unit Award. The unit flew the KC-135 from 1978 until its inactivation in 1987.
Reactivated in 1995 under Air Mobility Command at McConnell Air Force Base, Kansas. This activation brought with it the unique distinction of being the first associate tanker unit in the Air Force. The 931st began flying operations in May 1995, refueling the B-2 Spirit christened "Spirit of Kansas". With the activation, the 18th Air Refueling Squadron provided air operations for the group.
The 18th was redesignated a "super squadron" on 1 October 1997, doubling its size to 32 flying crews. The 931st was awarded the Air Force Outstanding Unit Award for meritorious service from 1 November 1995 to 31 October 1997. The 931st also won the Kansas Award for Excellence on 21 October 1997, becoming the first military unit to win this quality award. And, in recognition of meritorious service, the 931st received its third Air Force Outstanding Unit Award, for its performance between 1 November 1997, and 31 October 1999.
From April to July 1999, more than 70 members of the 931st were activated under a Presidential Selected Reserve Call-Up. In support of Operation Allied Force, members deployed to Morón Air Base, Spain and Naval Air Faciity Souda Bay, Crete. In support of Operation Northern Watch, members deployed to Incirlik Air Base, Turkey.
In March 2003, more than 100 members of the 931st were mobilized in support of Operation Iraqi Freedom. Most of the mobilized individuals were KC-135 aircrew members.
During Operation Iraqi Freedom, the Unit's security forces deployed a team to Kirkuk Air Base, Iraq (Forward Operating Base Warrior). This was the first "boots on the ground" combat mission since the unit's stand-up. The security forces team was integrated with various active-duty units, which formed the 506th Expeditionary Security Forces Squadron. The squadron was tasked with providing base perimeter security, entry-control and exterior/interior mobile patrols.Established as the 931st Troop Carrier Group, Medium and activated on 15 January 1963 (not organized)
