The Tupolev Tu-160 (Russian: Туполев Ту-160, NATO reporting name: Blackjack) is a supersonic, variable-sweep wing heavy strategic bomber designed by the Soviet Union. Although several civil and military transport aircraft are larger in overall dimensions, the Tu-160 is currently the world's largest combat aircraft, the largest supersonic aircraft, and the largest variable-sweep aircraft ever built. In addition, the Tu-160 has the greatest total thrust, and the heaviest takeoff weight of any combat aircraft, and the highest top speed of any current heavy bomber. Entering service in 1987 with the 184 Guards Bomber Regiment, based at Priluki, Soviet Union, the Tu-160 was the last strategic bomber designed for the former Soviet Union. Pilots of the Tu-160 call it the “White Swan”, due to its maneuverability and anti-flash white finish.
