The Tupolev Tu-160 is a supersonic, variable-sweep wing nuclear-capable heavy strategic bomber and airborne missile platform designed by the Tupolev Design Bureau in the Soviet Union in the 1970s. It is the largest and heaviest Mach 2+ supersonic military aircraft ever built and second to the experimental XB-70 Valkyrie in overall length and top speed. As of 2024, it is the largest and heaviest combat aircraft, the fastest bomber in use and the largest and heaviest variable-sweep wing airplane ever flown. The Tu-160 is operated by the Long Range Aviation of the Russian Aerospace Forces.

Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2.
