It was last assigned to the 4901st Support Wing (Atomic), at Kirtland Air Force Base, New Mexico, where it was discontinued on 31 August 1961.

It was tasked with testing all aircraft in the United States inventory for nuclear weapons delivery capability.

In January 1950 President Truman directed the Atomic Energy Commission (AEC) to emphasize the military becoming operational in delivering hydrogen bombs.

The group also recommended military characteristics and requirements for special weapons, provided facilities for training programs, and maintained an instrumentation laboratory and a technical liaison with the Armed Forces Special Weapons Project, AEC, and others.

[9] In 1957, AFSWC, including the group, assisted Air Defense Command (ADC) with the loading of the first operational Douglas MB-1 Genie rocket onto a Northrop F-89J Scorpion aircraft.

Other aircraft tested by the group included the B-29 and B-50D Superfortress, the B-36H Peacemaker, B-45 Tornado, B-47 Stratojet, B-57 Canberra, and B-66 Destroyer bombers.

The group was inactivated in 1961 following the 1958 moratorium agreed to by the United States and the Soviet Union on atmospheric nuclear testing.
