Nicknamed the "Bone" (from "B-One"), it is designed for high-speed, low-altitude penetration with a long range.
It holds almost 50 world records for speed, payload, range, and time of climb in its class.
The B-1B can carry the largest conventional payload of both guided and unguided weapons in the Air Force inventory.
It is powered by four GE Aviation F101-GE-102 turbofan afterburning engines.
