The Tupolev Tu-160 (NATO reporting name Blackjack) is a supersonic, variable-geometry heavy bomber designed by the Soviet Union. Similar to the B-1 Lancer but with far greater speed and range, it is the heaviest combat aircraft ever built. Introduced in 1987, it was the last Soviet strategic bomber designed, but production of the aircraft still continues, with 16 currently in service with the Russian Air Force. Its pilots call the Tu-160 the "White Swan", due to the surprising maneuverability and antiflash white finish of the aircraft.
