The Tupolev Tu-70 (Russian: Туполев Ту-70; NATO reporting name: Cart) was a Soviet passenger variant of the Tu-4 bomber (which was reverse-engineered from the American Boeing B-29 Superfortress) and designed immediately after the end of World War II. It used a number of components from Boeing B-29s that had made emergency landings in the Soviet Union after bombing Japan. It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946. The aircraft was successfully tested, recommended for serial production, but ultimately not produced because of more pressing military orders and because Aeroflot had no requirement for such an aircraft. A military cargo aircraft version was the Tupolev Tu-75.
