A wire-guided missile is a missile guided by signals sent to it
via thin wires reeled out during flight. This guidance system is most common for anti-tank missiles, where its ability to be used
in areas of limited line-of-sight make it useful, while its limited maximum range, that of the wires, is not a serious
concern.
Wire guidance is obviously limited by the length of the wire; the longest-ranged wire-guided missile in current use is the
Tube-Launched, Optically Tracked, Wire-Guided Missile System
(TOW), with a range of 3750 m [1] .
Wire guidance was first employed by the Germans during World War II. Most of their developments used radio control, but as the British proved to be able
to jam anything they used, rushed projects were started in 1944 in order to develop
alternatives. The first system to be modified in this fashion was the Henschel Hs 249B anti-shipping
missile, but by the time it was ready it was too late to be useful as the Allies had
already landed strong forces in France. Other examples included the X-4 anti-aircraft missile,
and the X-7 anti-tank version
of the X-4.
In the post-war era it was the X-7 that had the most effect on other military thinkers. By the early 1950s a number of experimental systems had been developed, leading to their widespread deployment in the late
1950s and early 1960s. Large numbers of Israeli tanks were destroyed using wire guided missiles during the Yom Kippur War of 1973. Wire guidance has remained the main system for most smaller weapons, although
laser beam riding systems have come into use for the anti-aircraft role, and some longer range anti-tank use (notably
the US's helicopter-launched Hellfire missile. The US Army's new Javelin anti-tank missile uses neither wires nor lasers;
the missile has a small thermal imaging TV camera in the nose and a computer that is sufficiently sophisticated that once locked
onto a tank, it will follow it autonomously, even if it is moving.
