As of early 2019, it was uncertain whether the Kh-15 was in service, with rumors that it had been retired or placed in storage.[2]
Development
In 1967, MKB Raduga started developing the Kh-2000 as a replacement for the Kh-22 (NATO reporting name AS-4 Kitchen) heavy anti-shipping missile.[1] Development of the Kh-15 started some time in the early 1970s.[3] The sophistication of the design made it suitable for other roles, and a nuclear-tipped version was developed in tandem with the conventionally armed variant.[1] An upgrade under development was cancelled in 1991, but reports in 1998 suggested an upgraded Kh-15 might be fitted to Su-35 (Flanker-E) tactical aircraft.[3]
Design
The Kh-15 climbs to an altitude of about 40,000 m (130,000 ft) and then dives in on the target, accelerating to a speed of about Mach 5.[1]
