The serial fighter Yak-15 was taken as a base of the construction of training aircraft Yak-21 in Yakovlev design office. The armament was taken away and on its place in front of pilot's cabin, designers placed the second cabin for the trainee. Simultaneously with Yak-21, with regard for heightened demands to fighter, the staff of Yakovlev design office was working out a single sealer fighter Yak-17 and a two-seater fighter Yak-21T(Yak-17UTI). Flying tests of the first training aircraft Yak-21 started in April, 1947 Although the aircraft flew well, the tests were stopped, because it had already become clear that Yak-21T(Yak 17UTI) would have better characteristics.
