Rockwell / Boeing B-1 Lancer Specification & Technical Data

The Rockwell (now part of Boeing) B-1 Lancer is a four-engine supersonic variable-sweep wing, jet-powered 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 penetration with long-range and Mach 1.25 speed capability at high altitude.
