The B-1B is a multi-role, long-range bomber. The B-1 has a blended wing body configuration, along with canards and variable-geometry wing design and turbofan engines, to improve range and speed with enhanced survivability. Forward wing settings are used for takeoff, landings and high-altitude maximum cruise. Aft wing settings are used in high subsonic and supersonic flight, enhancing the B-1's performance. The wings of the B-1B originally were cleared for use at settings of 15, 25, 55, and 67.5 degrees. The 45-degree setting was later cleared in 1998–1999.
