The Martel is an Anglo-French missile. The name Martel is a contraction of Missile, Anti-Radiation, Television, referring to the guidance options. There are two variants, the passive radar anti-radiation missile version, AS.37, and the television guided anti-ship missile, AJ 168.

An anti-ship missile is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way.
