Another US strategic bomber, the Rockwell B-1 Lancer is a variable-wing supersonic bomber designed for strategic strikes against enemy targets. It came into being during the 1960s as a replacement or supplement for the B-52 Stratofortress, which lacked supersonic capability.
The B-1 Lancer, affectionately referred to as the “Bone” by its operators, found itself caught in an awkward phase of aviation development. The B-1 came along after the age of subsonic bombers but before the full adoption of stealth design in aviation. Despite this, it entered service in 1986 as a nuclear bomber and has remained active in a variety of roles since then.
The variable wing design gives it a lot of flexibility, and the four General Electric F101 augmented turbofan engines deliver power and true supersonic speed - Mach 1.25 or more. The payload is impressive: up to 75,000 pounds of ordnance depending on the mission. While not a high-speed stealth bomber, the B-1 Lancer is still formidable.
