USAF 68th Bombardment Squadron Patch.

USAF 68th Bombardment Squadron was used as an operational training unit for B-29 aircrews and maintenance personnel. It was deployed to the Far East Air Forces during the Korean War. The unit replaced its propeller-driven B-29s with new Boeing B-47E Stratojet swept-wing medium bombers in 1953. These machines were capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. In the late 1950s, the B-47 was considered to be reaching obsolescence, and was being phased out of SAC's strategic arsenal. The squadron began sending aircraft to other B-47 wings as replacements in late 1959, while being phased down for inactivation in 1960. This patch measures 3.5" by 2.5", used condition. Patch has "cheese cloth" backing. Very rare.
