B-1B Lancer
Rockwell International’s B-1 was designed to combine the speed of the B-58 and the range/payload of the B-52, ideally replacing both of the aging aircraft. But a stealth bomber in the works and the development of nuclear-armed cruise missiles resulted in the cancellation of the B-1 project in 1977. Revived under the Reagan Administration as the B-1B, the bomber sacrificed speed for low-altitude performance and the “Bone” entered service in 1986 – trading out its nuclear weapons for conventional bombs in 1995.
