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.

The group was equipped with Fairchild C-119 Flying Boxcars for Tactical Air Command airlift operations.

The group flew overseas missions, particularly to the Far East and Southeast Asia during that period, being relieved from active service in June 1969.

Inactivated on 1 July 1973 as part of a reorganization of Military Airlift Command assets, personnel and equipment being assigned directly to its host 349th MAW.

On 1 April 1985 the group was again activated as the 939th Aerospace Rescue and Recovery Group when the 304th Aerospace Rescue and Recovery Squadron at Portland International Airport equipped with Lockheed HC-130 Hercules aircraft transferred from March Air Force Base, California in addition to its Bell HH-1 Hueys.
