In 1946 the 715th transitioned to the B - 29 and was reassigned to the 509th Composite Group , the same organization that ended the war in the Pacific with the dropping of two atomic bombs on Japan . The 715th continued service flying the B - 29 , B - 50 , and B - 47 until it was inactivated in 1966 . The 715th was reactivated in 1970 at Pease AFB as the first operational FB - 111 squadron . History . World War II . Activated in mid - 1943 as a B - 24 Liberator heavy bomb squadron , trained under Second Air Force . Deployed to England in the European Theater of Operations ( ETO ) during November 1943 , assigned to VIII Bomber Command as a strategic bombardment squadron . Participated in the air offensive over Nazi Germany and Occupied Europe until German capitulation in May 1945 . Personnel demobilized in England and returned to the United States ; squadron reassigned to Second Air Force and re - equipped with B - 29 Superfortress es , being trained for deployment to Pacific Theater . Japanese capitulation canceled deployment and was assigned to Fort Worth AAF , Texas as Continental Air Forces , later Strategic Air Command squadron . Cold War . Original host unit inactivated due to budget and personnel shortages in May 1946 ; squadron reassigned and consolidated into 509th Composite Group . B - 29s modified into atomic capable silverplate configuration and stood nuclear alert . Began upgrading to the new B - 50 Superfortress , an advanced version of the B - 29 in 1949 . The B - 50 gave the unit the capability to carry heavy loads of conventional weapons faster and farther as well as being designed for atomic bomb missions if necessary . Squadron deployed to SAC airfields in England , and also to Andersen AFB , Guam on long - term deployments in the 1950s . By 1951 , the emergence of the Soviet Mig - 21 interceptor in the skies of North Korea signaled the end of the propeller - driven B - 50 as a first - line strategic bomber . The squadron moved into the jet age when it received new , swept wing B - 47 Stratojet s in 1955 which were designed to carry nuclear weapons and to penetrate Soviet air defenses with its high operational ceiling and near supersonic speed . The squadron flew the B - 47 for about a decade when by the mid - 1960s it had become obsolescent and vulnerable to new Soviet air defenses . The squadron began to send its stratojets to AMARC at Davis - Monthan AFB for retirement in 1965 , and the unit inactivated in 1966 . Reactivated as General Dynamics FB - 111 strategic bomber squadron in 1970 when aircraft became part of SAC ' s nuclear deterrent force . Inactivated in 1990 with retirement of weapons system .
