516th Aeronautical Systems Group
# 516th Aeronautical Systems Group

The 516th Aeronautical Systems Group is an inactive group of the United States Air Force (USAF). It was last assigned to the 516th Aeronautical Systems Wing of Air Force Materiel Command at Wright-Patterson Air Force Base, Ohio.

The unit was first activated in the fall of 1943 as the 31st Transport Group and transported high priority cargo and mail in the United Kingdom and delivered aircraft to combat airfields. Following the invasion of Normandy, the group moved to the continent and, although re-designated the 516th Troop Carrier Group, continued in this role until it was inactivated in Austria in the fall of 1946.

The group was activated in the Air Force Reserve in 1949 and trained at Memphis Municipal Airport, Tennessee. In 1951, it was called to active duty for the Korean War and served until 1953 when it was replaced by the 463d Troop Carrier Group.

In 1955, the unit was activated at Sewart Air Force Base, Tennessee as a rotary-wing troop carrier unit in a test of the USAF's ability to support United States Army assault operations. It participated in Operation Sage Brush, which was, in part, a test of this concept. The group was inactivated the following year and its aircraft distributed to helicopter support organizations.

Beginning in 2005, the C-17 Systems Group, later consolidated as the 516th Aeronautical Systems Group, was responsible for modernization, development, test, production, deployment and sustainment of new and existing aircraft systems to meet Air Mobility Command, Air Force Reserve Command, Air National Guard, and special operations forces requirements in global mobility mission areas.

## History

### European operations

The group was formed in October 1943 as the 31st Transport Group in England when the support requirements for Eighth and Ninth Air Forces expanded beyond the capability of the 27th Air Transport Group. It was assigned a combination of transport squadrons for delivering high priority cargo and mail and ferrying squadrons to deliver aircraft from depots to combat bases. The group was initially activated at Camp Griffiss, which was the headquarters of Eighth Air Force and its VIII Air Force Service Command, but the group moved in a few days to RAF Grove, where one of the largest depots in the European Theater was located.

The group flew its first mission to the continent of Europe five days after D-Day, when Col. Feldman, the group commander, delivered a load of supplies to the Normandy Beachhead in a Douglas C-47 Skytrain and returned to England with Allied casualties. A detachment of the group was established near Omaha beach to organize the receipt of air freight and the return of wounded. In the first days of the Normandy campaign, the group's planes flew from a field within the range of enemy small arms fire. Traffic there temporarily exceeded that of many of the busiest transport bases in the United Kingdom, and it was claimed that it was the "busiest airdrome in the world."

In September 1944, the group moved forward to Querqueville Airfield, an advanced landing ground in France, and in the same month was combined with the 27th Air Transport Group into the 302d Transport Wing.

In September 1945, USSTAF organized the European Air Transport Service (Provisional), using the personnel of the 51st Troop Carrier Wing and the 31st was transferred to the control of the 51st wing. Shortly thereafter, it was redesignated as the 516th Troop Carrier Group. It continued to provide airlift support to the United States Air Forces Europe until inactivating in September 1946.

### Reserve training and Korean War callup

The group was allotted to the reserves in 1949 and assigned to the 516th Troop Carrier Wing as Continental Air Command implemented the wing base reorganization. The group trained under the supervision of the 2584th Air Force Reserve Training Center at Memphis Municipal Airport, Tennessee until April 1951. The group was called to active duty that month and participated in tactical exercises and worldwide airlift. It converted from Curtiss C-46 Commando to Fairchild C-119 Flying Boxcar aircraft in 1952. The 516th was replaced by the 463d Troop Carrier Group in January 1953.

### Helicopter assault operations

The group was reactivated in 1955 at Sewart Air Force Base, Tennessee as the 516th Troop Carrier Group, Assault, Rotary Wing in part to test the United States Air Force's ability to provide helicopter airlift to the Army. The group was initially equipped with Sikorsky H-19 helicopters, but soon replaced them with Piasecki H-21s. Its operations included participation in Operation Backlash II, which was a survey mission to fix the location of radar sites and support the construction of the Mid-Canada Line. The group also tested the evacuation of key high ranking personnel from Washington DC in the event of a nuclear attack.

The conflict between the Army and the Air Force concerning the use of Air Force helicopters to support Army assault operations was tested in Exercise Sage Brush. The 516th operated as part of the 20th Combat Airlift Division (Provisional) supporting Army Group Gulf, the aggressor force. The group's H-21s were dismantled and transported in Douglas C-124 Globemaster II aircraft in a test of air mobility. Following this test, the 516th group was inactivated in July 1956. The helicopters of the group's three squadrons were transferred to the 20th, 23d and 24th Helicopter Squadrons, whose mission was support for routine Air Force activities. Three months later, the group's squadrons were reactivated at Stewart as Fairchild C-123 Provider units, but the 516th was not activated with them, instead, they were attached to the 513th Troop Carrier Group.

### Systems development

In January 2005, Air Force Materiel Command (AFMC) implemented the Air Force Materiel Command Transformation in its Aeronautical Systems Center, replacing its traditional systems development offices with wings, groups, and squadrons. As a result, it activated the C-17 Systems Group at Wright-Patterson Air Force Base, Ohio to direct the modernization, development, test, production, deployment, and sustainment of C-17 aircraft, engine, support, and training systems. In the following year, the Air Force consolidated these new units with numbered units with past histories. As a result, the new systems group was consolidated with the 516th and the unit was renamed the 516th Aeronautical Systems Group. In June 2010, the group was inactivated as AFMC returned to its previous organizational model in the Air Force Acquisition Improvement Plan.
