2022年3月15日 · Page details technical specifications, development, and operational history of the AT-4 (Spigot) / 9M111 (Fagot) Anti-Tank Guided Missile (ATGM) System including pictures.

A portable anti-tank complex with a semi-automatic guidance system designed to destroy visually detected stationary and moving (up to 60 km/h (60 mph)) armoured targets at ranges from 70 m (75 yd) to 2,000 m (2,500 yd) 2). The individual launchers (9P135, 9P135M, 9P135M-1) are mutually compatible with all missiles in use (9M111, 9M111-2, 9M111M).

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.
