Javelin is a British, man-portable surface-to-air missile, formerly used by the British Army and Canadian Army. It can be fired from the shoulder, or from a dedicated launcher known as Javelin LML—Lightweight Multiple Launcher. Capable of being vehicle mounted, the LML carries three rounds.
The missile was developed as a replacement for the Blowpipe missile, which had proven largely ineffective in the Falklands War, with only two hits recorded out of more than 100 launches. Javelin is slightly more compact, uses Semiautomatic Command Line of Sight (SACLOS) radio frequency guidance and is fitted with Semi and improved warhead. Javelin unlike Blowpipe only have to point the launcher at the target. The operator is equipped with a 6× magnification sight and a long range T.V. camera to locate targets. Although the Javelin's accuracy is somewhat susceptible to smoke, fog, or clouds, it is claimed to be virtually impossible to decoy it away from a target with flares
It was replaced in front line British service by the Javelin S-15, sold commercially as the Starburst surface-to-air missile in 1993 (radio frequency guided Javelin was retained for some time thereafter for training purposes), and later by the Starstreak starting around 1997. The Canadian Forces have retired it without replacement.
