With the phaseout of the FB-111 and closure of Pease, the squadron moved as a paper unit to Whiteman Air Force Base, Missouri in 1990.

The squadron was then reassigned for advanced training and received B-29s at Fairmont Army Air Field, Nebraska during the late spring and summer of 1944.

They were then deployed to North Field (Tinian) in late May 1945, flying non-combat missions practicing atomic bomb delivery techniques.

The B-50 gave the unit the capability to carry heavy loads of conventional weapons faster and farther as well as being designed for nuclear deployment missions if necessary.

By 1951, the emergence of the Soviet Mikoyan-Gurevich MiG-15 interceptor in the skies of North Korea signalled the end of the propeller-driven B-50 as a first-line strategic bomber.

Received new, swept-wing Boeing B-47 Stratojets in 1955 which were designed to carry nuclear weapons and to penetrate Soviet air defenses with their high operational ceiling and near supersonic speed.
