The Yakovlev Yak-30 (NATO reporting name Magnum) was Yakovlev''s entry in a competition for the first military jet trainer aircraft designed for Warsaw Pact nations. Designed to succeed the Yak-17UTI, it also led to the development of the Yakolev Yak-32 sport jet. The Yak-30 lost to the L-29 Delfin, and neither it or the Yak-32 entered production. In 1959 the VVS held a competition for the first purpose built jet trainer to enter service with the Soviet Union and Warsaw Pact nations. Prior to this time all Soviet jet trainers, such as the Yakovlev Yak-17UTI, had been modified from existing jet fighters. Since Yakovlev had produced most of the Soviet Union''s trainer aircraft since WWII, wining the competition was extremely important, as the winner would be produced extensively for many years to come. Yakovlev''s entry in the competition was the Yak-30. Surprisingly, it was the only competitor from within the Soviet Union.
