AT-4 (Spigot) / 9M111 (Fagot)

History

The AT-4 Spigot wire-guided anti-tank missile system is similar to the French-made MILAN system, but smaller. It fires SACLOS (Semi-Automatic Command Line of Sight) anti-tank wire-guided missiles. The system was designed by the Tula Mechanical Design Bureau in 1962 and put into production in 1970.

Developed as an infantry and vehicle tank killer, the AT-4 was a key component of the Soviet anti-tank forces. The weapon system weighs just over 25 pounds. The initial muzzle velocity at launch was 80 meters per second, which increased to 186 meters per second in flight.

Because it is a wire guide system, the operator must keep aiming at the target at all times.

The launchers for 9M111, 9M111-2 and 9M111M missiles are 9P135 (base launcher), 9P135M (casing and spandrel missile system), 9P135M1 (updated/improved 9P135 system), 9P135M2 (updated/improved 9P135 - system)), 9P135M3 (with thermal imaging night vision) and 9S451M2 (with night vision).

The AT-4 is in service with many countries around the world - many of which were formerly pro-Soviet countries and peoples.

The AT-5 "Spandrel" is a similar weapon system developed with the AT-4.
