Take a ride on one of the most powerful planes used by the United States Air Force. The B-1 has a blended wing body configuration, with variable-sweep wing, four turbofan engines, triangular fin control surfaces and cruciform tail. The wings can sweep from 15 degrees to 67.5 degrees (full forward to full sweep). Forward-swept wing settings are used for takeoff, landings and high-altitude maximum cruise. Aft-swept wing settings are used in high subsonic and supersonic flight. The B-1’s variable-sweep wings and thrust-to-weight ratio provide it with improved takeoff performance, allowing it to use shorter runways.
