The B-1 bomber can carry the largest weapons payload in the Air Force - up to 75,000 pounds - and travel long range to deliver it. A key component to the Lancer's efficiency is its wing configuration. The forward wing setting is used for takeoff, landing and refueling. When pointed to the rear, the wings aid in subsonic and supersonic flight.
