Rockwell B-1 Lancer
The
Rockwell B-1 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").
