The Yakovlev Ya-21, also known as the UT-21, No.21 or No.25, was a single-seat high-speed sport aircraft and fighter-trainer built in the Soviet Union in the late 1930s. It was derived from the UT-1 by fitting an imported 220 hp Renault 6Q-01 inverted six-cylinder inline engine, an enclosed rear cockpit under a sliding canopy, split flaps and a synchronised 7.62 mm ShKAS machine gun. The only example was later converted into the No.25 with a Voronezh MV-6 engine. Neither version was produced because the bureau was concentrating on combat aircraft such as the BB-22.
