MKB Raduga's Kh-22 (Russian: Х-22; AS-4 'Kitchen') is a large, long-range anti-ship missile developed by the Soviet Union. It was intended for use against US Navy aircraft carriers and carrier battle groups, with either a conventional or nuclear warhead.

After analyzing World War II naval battles and encounters in the late 1940s and early 1950s, Soviet military thinkers assessed that the times of large seaborne battles were over, and that stand-off attacks were the way to neutralize and incapacitate large battle groups without having to field a similar force against them. Substituting cruise missiles for air attacks, VVS and AV-MF commanders set about to convert their heavy bombers to raketonosets, or missile carriers, which could be launched against approaching enemy fleets and task forces from coastal or island airfields. The Kh-22 (Complex 22) weapon was developed by the Raduga design bureau and used to arm the Tupolev Tu-22M.

The Kh-22 uses an Isayev liquid-fuel rocket engine, fueled with TG-02 (Tonka-250) and IRFNA (inhibited red fuming nitric acid), giving it a maximum speed of Mach 4.6 and a range of up to 600 km (320 nmi). It can be launched in either high-altitude or low-altitude mode. In high-altitude mode, it climbs to an altitude of 27,000 m (89,000 ft) and makes a high-speed dive into the target, with a terminal speed of about Mach 4.6. In low-altitude mode, it climbs to 12,000 m (39,000 ft) and makes a shallow dive at about Mach 3.5, making the final approach at an altitude under 500 m (1,600 ft). The missile is guided by a gyro-stabilized autopilot in conjunction with a radio altimeter.
