The Tupolev Tu-75 (Russian: Туполев Ту-75) was a military transport variant of the Tu-4 bomber, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress.
A new, narrower fuselage was designed, which included a rear cargo hatch, a vehicle loading ramp and paratroop exit doors.
[2] Construction of the first prototype was quite prolonged; the aircraft was not finished until November 1949, with its first flight taking place on 21 January 1950.
The prototype was used by the MAP (Russian: Ministerstvo Aviatsionnoy Promyshlennosti – Ministry of Aviation Industry) until it crashed in October 1954.
