AT-4 Spigot B / 9M111* Fagot-M

The system is designed to defeat stationary and moving armored targets as well as light field fortifications and weapon emplacements.

The missile is guided semiautomatically with commands transmitted over a wire link.

The system components:
- launcher which is essentially a tripod with fine-laying elevating and traversing mechanisms, guides for missile placement and control equipment comprising a tracker and a control unit;
- guided missile kept in a sealed launching transporting container.

The launcher of the modernized Fagot-M ATGM system mounts a 1PN65 thermal imager operating on thermal radiation of a target.
To check the launcher, missile and thermal imager during storage and operation, use is made of the 9V812M-1 and 9V811M test sets for the launcher and missile and the 9V974 test set for the thermal imager (same as for the Konkurs ATGM system).

The system fires the 9M111 and 9M111M missiles. The 9M113 and 9M113M missiles can also be used.
