The UT – 1 was designed as a single-seater advanced trainer and aerobatic airplane by the team led by Alexcander sergeevich Yakovlev. The first prototype, designated the AIR-14, was flown in early 1936. Among other improvements, the 100 hp Shvetsov M-11 radial was changed to the more powerful 115 hp M-11G. The plane received the designation UT-1 (primary/advanced trainer); despite this designation, it was not suitable for primary training.
Soviet pilots broke several records on the UT-1 before the war, some on its floatplane variant. In total, 1,241 aircraft were built between December 1936 and 19740.
