These systems are intended to engage pinpoint line-of-sight targets such as armored vehicles, observation posts, weapon emplacements, and others. A target is illuminated by a laser beam during projectile flight and locked on by the homing head, while the projectile is controlled by thrusters.

The system components: 30F38 Santimetr controlled projectile, Smelchak controlled mortar shell, laser ranger designator, and 1A35 shot synchronizing system.
