History
The Yakovlev UT-3 was designed as a training aircraft to offer instruction to pilots of multi-engined aircraft, gunners, bombardiers, and radio operators. Construction was mainly of wood, with fabric covering and some steel tubing. Imported French Renault 6Q engines were used on the prototypes, but production models probably had a Voronezh MV-6, a Russian copy of the French powerplant. The prototypes first flew in 1938, and some were equipped with armament, 7.62 mm machine guns and bombs, but production models were unarmed. Production began at two plants, No. 272 at Kazan, and No. 135 at Leningrad. Only a small number, around thirty, had been produced when the authorities decided to use combat aircraft for this type of training, so further production was cancelled.
