The Raduga Kh-15 or RKV-15 (Russian: Х-15; NATO: AS-16 "Kickback"; GRAU:) is a Russian hypersonic aero-ballistic air-to-ground missile carried by the Tupolev Tu-22M and other bombers. Originally developed as a standoff nuclear air-to-ground missile similar to the U.S. Air Force's AGM-69 SRAM, versions with conventional warheads have been developed.

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]

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]

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]

It entered service in 1980. It can be carried by the Su-33, Su-34, Tu-95MS-6 'Bear-H', Tu-22M3 'Backfire C', and Tu-160 'Blackjack'.^[4]
