China has long employed cruise missiles for naval attack missions, building three families of anti-ship missiles.
These include two series of anti-ship missiles which derive from the early pioneering Soviet P-21 STYX anti-ship missile...
A third family is based on technology obtained from French Exocet anti-ship missiles and include ship, submarine and air launched versions of the rocket-powered 40km range YJ-81 (C-801) and the 120km range turbojet-powered YJ-82 (C-802).
