ww2dbaseThe UT-1 single-seat trainer monoplane aircraft design by Alexander Sergeyevich Yakovlev first took flight, under designation AIR-14, took flight in 1936. The final design entered mass production in Dec 1936; the "UT" in the designation stood for uchebno-trenirovochnyi, or primary/advanced trainer, although it was generally regarded as suitable for advanced trainees only. In 1939, the design was modified by moving the engine forward by 26 centimeters (about 10 inches) to improve handling. Production ceased in 1940; 1,241 examples were built by this time. After the German turned on the Soviet Union in 1941, they were pressed into front line service as reconnaissance aircraft. A small number of them were equipped with ShKAS machine guns and RS-82 rockets to serve as ground attack aircraft; these machines were designated UT-1B.
