This artillery system is intended to engage coastal, sea and air targets. The basic components of the artillery system are:
- naval two-band control system comprising electronic and TV target sighting channels and a computer;
- 130mm gun mount (one or two pieces) with turret-mounted Kondensor optical sighting equipment;
- various types of artillery ammunition for firing at coastal, sea and air targets (including ammunition with impact base and proximity point fuzes, as well as practice and discharging rounds);
- equipment for interface with external sources of information and combat use.

Within the ammunition range, the system is capable of ensuring:

- shelling of shore sectors, docking and other coastal facilities, fortified points during amphibious landing operations of naval forces;
- fire fight with surface ships; - engagement of various air threats, including antiship missiles flying at extremely low altitudes.

This turreted gun mount is fitted with two automatic guns and fuze setters, monoblock barrels with casings and pneumatic recuperators, vertically sliding wedge breechblocks with synchronized trigger mechanisms, springloaded rammers and hydraulic recoil brakes. The barrels are continuously cooled by pumping liquid coolant between the casing and the barrel. First loading is done by hydraulic charging. Ammunition feed ensures a practical rate of fire virtually equal to the cyclic rate. The gun mount is remotely laid by electric drives. The control system ensures fire adjustment and effective engagement of targets within the range of the weapon system, as well as crew drills. The gun mount rate of fire is adjustable from single shots or salvoes to bursts.

The artillery system is installed on Projects 956 and other ships.
