One of the many remarkable aircraft described in The Osprey Encyclopedia of Russian Aircraft 1875-1995, the Yak-1000 was an experimental fighter designed to explore configurations for a supersonic interceptor.

Contemporary of the La-190 and similarly powered by an AL-5 turbojet, the Yak-1000 transonic fighter featured a dipped narrow-delta wing platform with tapered trailing edges, a tailplane of similar configuration, and a zero-track tricycle undercarriage with outrigger stabilising wheels. A maximum speed of 714 mph (1 150 km/h) was anticipated, but its characteristics were allegedly poor and trials were abandoned at an early stage.
