B-1B Lancer

Originally designed as a high-altitude nuclear striker, the "Bone" was converted in the 1990s into a supersonic conventional heavy bomber. It relies on variable-geometry wings to fly fast at low altitudes, masking itself in terrain noise to penetrate enemy air defenses.

Quick Stats

• Top Speed: Mach 1.25 (900+ mph)

• Max Payload: 75,000 lbs (Internal) + 50,000 lbs (External)

• Crew: 4 (Pilot, Co-Pilot, and 2 Combat Systems Officers)

• Primary Role: Supersonic Heavy Precision Strike

What Makes It Special

• Variable-Sweep Wings: Sweeps its wings back to 67.5 degrees for supersonic dashes, and extends them forward to 15 degrees for heavy-payload takeoffs and long loiter times.

• Largest Payload Capacity: Features three internal weapons bays that carry more internal weight in bombs and standoff missiles than any other operational U.S. bomber.
