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 afterburning 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 have made it a cornerstone in its category of aircraft.
