Rockwell B-1B Lancer
Role: strategic heavy bomber
Builder: Rockwell (North American Aircraft), now Boeing
Variants: B-1B, (B-1A)
The B-1 bomber features a long and slim fuselage, a variable-geometry wing with a maximum sweep
of 67 degrees and two small canard foreplanes and is powered by four F101 turbofan engines which
lay below the wings.
The B-1A was the design for a supersonic nuclear capable strategic bomber able to penetrate
Soviet airspace at high altitude during the Cold War. Four prototypes of the B-1A were built.
The production B-1B was the B-1 design optimized for low-level high-subsonic missions. Changes from the
original B-1A design include strengthened landing gear, redesigned wing gloves, fixed engine inlets and
significant use of composite materials in the aircraft's construction to reduce weight, radar absorbing
material is used to cover much of the airframe to reduce the radar cross-section.
