[edit] Development
On February 21, 1949 a Sovmin order requested the Yakovlev OKB to design a lightweight interceptor capable of Mach 0.97 at 4,000 m (13,000 ft) and utilizing the Klimov VK-1 engine which first appeared on Mikoyan-Gurevich MiG-15 and MiG-17 fighters. The new aircraft first flew in July 1949, achieving supersonic speed (Mach 1.03 at 10,000 m (33,000 ft)) in a shallow dive during one of the test flights. The Yak-50 was delivered for government testing in June 1950. In the course of the evaluation the aircraft was commended for excellent performance, but a number of deficiencies were also noted. In particular, the airbrakes were ineffective, there was significant yaw at transsonic speeds making accurate gunfire impossible, and the aircraft was difficult to land in significant crosswinds. Ultimately, the upgraded MiG-17 was selected over Yak-50. The superior performance of the Yak was achieved at the expense of fuel capacity and the advantage was considered insufficient to justify producing two very different aircraft with the same engine.
