Low-wing passenger development of the Tu-4 bomber. Differed from only by fuselage construction and deleted armament. Passenger 'luxury' variant for 48 passengers and crew of 8 was developed in parallel with the bomber.

On design stage decision was made to stretch the fuselage, increase diameter and accommodate 72 passenger and crew of 6. Even in this configuration Tu-70 was a comfortable airliner with pressurized fuselage, heating and ventilation systems, kitchen, refrigerator and all other passenger/crew necessities. In construction of the Tu-70 some parts from original USA-built B-29 Superfortress.

First flight (pilot F.F.Opadchij) occurred on November 27, 1946. On August 3, 1947 Tu-70 was demonstrated at Tushino Parade.It easily passed all trials and was ready for production (3/4 parts of series built Tu-4 were already available). Nonetheless, it did not became the first large airliner. Economical situation in the USSR and limited demand for air travel made Tu-70 (as well as its rival Il-18) premature. Large passenger aircraft will enter the scene 10 years later.

For some time lone Tu-70 was used as a VIP official transport. At some point of its history airliner was 'confiscated' by V.I.Stalin (son of Joseph Stalin who served as a chief command of MVO aviation) and used to carry... hockey and football teams of the VVS.
