National origin	Soviet Union
Manufacturer	Tupolev
Designer	Andrei Tupolev
Number built	None
Developed from	Tupolev Tu-101

The Tupolev '102' and Tupolev '101' were 1950s projects for a turboprop airliner and assault transport by the Tupolev Design Bureau. The aircraft designs were almost identical but the '101' had a rear loading ramp and tail barbette for two Nudelman-Rikhter NR-23 cannon. The internal arrangement also differed with the '101' cabin being unpressurised apart from the flightdeck and a small cabin for ten passengers, whilst the '102's pressurised cabin was in one section, configured for 40 passengers.

Similar requirements were also issued to OKB-23 (V.M. Myasischchev) and OKB-473 (Oleg K. Antonov), resulting in the Antonov An-8 which formed the design root of all Antonov's turboprop transports up to the An-22.
