"This article is about the interceptor from the 1940s. For the trainer from the 1960s of the same name, see here"

The Yakovlev Yak-30 was a Soviet interceptor from the 1940s. Derived from the Yak-25 from which it differed primarily in having wings sweptback 35° at quarter chord, the Yak-30 retained the fuselage, tail surfaces and undercarriage of the earlier fighter fundamentally unchanged, together with the three NR-23 cannon armament. Powered by a 1590 kg RD-500 turbojet, the first of two Yak-30 prototypes was flown on 4 September 1948. The second prototype, the Yak-30D, which joined the flight test programme early in 1949, had a 38 cm section inserted in the aft fuselage, revised mainwheel doors forming a large section of the fuselage skinning, Fowler-type flaps in place of split flaps, increased fuel and ammunition capacity, and changes to the oxygen system and radio equipment. The Yak-30D was also fitted with air brakes on the aft fuselage. Normal loaded weight (without external fuel) was increased by 110 kg. Although the modifications introduced by the Yak-30D eradicated several shortcomings displayed by the first prototype, the first production deliveries of the superior MiG-15 were already taking place by the time that the improved version of the Yakovlev fighter entered flight test, and the results of NII V-VS trials were, therefore, little more than academic.
