The Rockwell (now Boeing) B-1B 'Lancer' is a four-engine supersonic variable-sweep wing, jet-powered heavy strategic bomber used by the United States Air Force (USAF). It was first envisioned in the 1960s as a supersonic bomber with Mach 2 speed, and sufficient range and payload to replace the Boeing B-52 Stratofortress. It was developed into the B-1B, primarily a low-level penetrator with long range and Mach 1.25 speed capability at high altitude. It is commonly called the "Bone" - originally from "B-One".
