History. The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber designed for long-range missions. It was initially conceived in the 1970s as a replacement for earlier bombers, featuring advanced avionics, stealth characteristics, and the ability to carry both conventional and nuclear weapons. The B-1’s variable-geometry wings allow it to adapt to high-speed, low-level penetration missions as well as high-altitude flight. Powered by four after-burning turbofan engines, it can reach speeds over Mach 1.2. The aircraft's design emphasizes flexibility, enabling it to perform strategic bombing, close air support, and maritime missions. The B-1 has undergone numerous upgrades over its service life, enhancing its precision strike capabilities and survivability. Its combination of speed, payload, and range makes it a key asset in modern air combat, with a distinct appearance and versatile operational role that has made it a cornerstone in its category of aircraft.
