130 mm/70 (5.1") AK-130
Updated 21 May 2006
The AK-130 is one of the most powerful gun systems used in the world today and is a fully automatic, dual-purpose weapon.  Design work was started by the PO Arsenal in 1967 on a single gun version designated as A-217.  However, the required rate of fire of 60 rounds per minute was not reached during trials, so it was decided to switch to a twin mounting.  The new system with a factory designation ZIF-94 used the same barrel and large number of components from the A-217.

The mountings are controlled by MP-184 Fire Control Radar Systems, which include a 2-band radar, low light TV, laser designator, system for selecting moving targets and an ESM system.  This system has a range of 75 km (41 nm).  The system provides the integration of all of the shipboard radars, exact measurement of all parameters of movement for all air, sea and land targets, exact bearing to the target, correction of shooting by splashes and automatic tracking of shells.

The mounts are triaxially stabilized and the barrels are liquid cooled.
