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.
The aircraft that used these missiles were the Blackburn Buccaneer (up to three TV or four ARM variant), the SEPECAT Jaguar (two), the Mirage III/F1 (one or two), and the Hawker Siddeley Nimrod (at least one). The Martel was suited to anti-ship attack with its long range and heavy warhead. There was not, at the time, a small radar homing missile like the AGM-84 Harpoon with an active radar, so the only viable solution was a video or ARM sensor. With a relatively long range, a heavy payload, and a subsonic speed, this missile compares more to an anti-ship weapon like the Exocet or the AS.34 Kormoran than an anti-radar missile. It weighs three times as much as the AGM-45 Shrike, with half the speed but much greater range and explosive power.
