The Tupolev Tu-4 (Russian: Туполев Ту-4; NATO reporting name: Bull) is a piston-engined Soviet strategic bomber that served the Soviet Air Force from the late 1940s to mid-1960s. The aircraft was a copy of the American Boeing B-29 Superfortress, having been reverse-engineered from seized aircraft that had made emergency landings in the USSR.
