The B-1 is a "swing-wing" strategic bomber of blended wing-body design intended for high-speed low-altitude penetration missions. Eventually, it will replace the aging B-52 bomber, operational since the 1950s. The B-1 uses shorter runways than the B-52, can carry twice the payload, and has a smaller radar profile than the B-52's, making it harder for the enemy to detect. Construction of the first prototype B-1A began in late 1972 and the first flight occurred on Dec. 23, 1974. By the end of June 1977, three B-1As had made 118 flights totaling 646 hours of flying time with over 21 hours at supersonic speed and more than 35 hours at high speed below 500 ft. B-1A production was canceled by presidental decision on June 30, 1977, but in Jan. 1982, as a result of another Presidental decision, the USAF directed Rockwell International to begin production of 100 B-1Bs, an improved version of the B-1A.
