In October 1951, the 373rd Bombardment Squadron was reactivated again with new Boeing B-47E Stratojet swept-wing medium bombers, capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. In the early late 1950s, the B-47 was considered to be reaching obsolescence, and began phasing out of SAC's strategic arsenal. B-47s were sent to the Aerospace Maintenance and Regeneration Center at Davis–Monthan in July 1959 and the squadron became non-operational. It was inactivated once more on 25 June 1961.
