The B-1B Lancer, often referred to as the “Bone” (a play on “B-One”), is a long-range, multi-mission, supersonic conventional bomber, which has been in service since the 1980s. It’s part of the Air Force’s strategic bomber trio, alongside the B-2 Spirit and the B-52 Stratofortress.
Pre-Takeoff
Before takeoff, the crew of four—comprising a pilot, co-pilot, and two weapon systems officers—conduct pre-flight checks, which include systems diagnostics, communication checks, and weather briefing. The aircraft is also loaded with fuel and, if it’s a mission scenario, armed with its intended payload. The B-1B can carry a large conventional payload of guided and unguided weapons in three internal bomb bays.
The Takeoff Roll
As the B-1B begins its takeoff roll, the pilots advance the throttles, and the four General Electric F101-GE-102 turbofan engines roar to life, each producing up to 30,000 pounds of thrust with afterburner. The sound is thunderous, a deep roar that can be felt in the chest as much as it can be heard. The aircraft accelerates rapidly down the runway.
Liftoff
The B-1B’s wings are positioned forward for takeoff, giving it the best lift-to-drag ratio. As it reaches takeoff speed, the pilot gently pulls back on the control stick, and the Lancer lifts off the runway. The takeoff is a display of raw power and grace, as the 190,000-pound bomber, fully loaded, climbs into the sky.
Post-Takeoff
Shortly after takeoff, the wings begin to sweep back, moving towards their most aerodynamic position for high-speed flight. This variable-sweep wing design allows the B-1B to adjust its aerodynamic profile for the optimal balance of speed, range, and payload capacity. The aircraft transitions to its mission profile, whether flying low to avoid radar detection or climbing to higher altitudes for a long-distance transit.
The Mission
Once airborne, the B-1B can execute a variety of missions. It’s capable of flying at high subsonic speeds at low altitude, making it difficult to detect by radar, a feature that is enhanced by its reduced radar cross-section. The Lancer can also reach supersonic speeds, over Mach 1, at higher altitudes. It has a range of approximately 7,455 miles (12,000 kilometers) without refueling, but with air-to-air refueling, it can essentially fly indefinitely, reaching any target worldwide.
The B-1B Lancer’s takeoff is just the beginning of its capabilities demonstration, serving as a reminder of the strategic and tactical flexibility this bomber brings to the U.S. Air Force and the deterrence it provides to the nation’s defense.
