The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It has been nicknamed the "Bone". It is one of the Air Force's three strategic bombers, along with the B-2 Spirit and the B-52 Stratofortress, as of 2024. Its 75,000-pound payload is the heaviest of any U.S. bomber.

A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be swept back and then returned to its original straight position during flight. It allows the aircraft's shape to be modified in flight, and is therefore an example of a variable-geometry aircraft.

The F-111 was the first variable-sweep wing aircraft to be put into production. Shown are three Australian F-111s.
