2 x AK-630M
The gun itself is a 6 barrel Gatling gun designated as AO-18. The barrels are in a single block, having exhaust-driven joint automatics. They are belt fed with a flat magazine in the AK-630 and a drum magazine in the AK-630M. These weapons form a part of a complete self-defense system called A-213-Vympel-A, which includes gun, radar, optical and TV control systems. A single MP-123 Vympel system can control two 30 mm guns or one 30 mm and one 57 mm gun. This system can engage air targets at ranges up to 4,000 m (4,400 yards) and surface targets at ranges up to 5,000 m (5,500 yards). The TV control system can detect MTB sized ships at the distance of 75 km (40 nm) and the fighter-size air targets at 7,000 m (7,600 yards). This system is completely automatic and does not require human supervision although it can be directed from optical control posts in case of damage or for firing on shore targets.
6 barrel Gatling gun designated as AO-18
The AK-306 (A-219) system was a modification of the AK-630 (A-213) system for use on light ships, like air cushion craft, ekranoplanes and small displacement motor boats. Externally, there was no difference between AK-306 and AK-630 guns, but internally instead of using the exhaust to power the automatics, the AK-306 (A-219) used electricity. This version also lacked radar control, being only optically guided, hence making it less of a anti-missile weapon and more of a surface-to-surface weapon. The design started in 1974 and the system was accepted into service in 1980. By 1986, 125 systems were in service.

The onboard Paket anti-submarine system provides self-defence for the vessel against enemy submarines and torpedoes.
Paket-E/NK system (2 x launchers, 8 x torpedoes)
The Paket-E/NK small-sized anti-submarine system with anti-torpedo is designed:
– to engage (destroy) submarines in ship’s close-in zone (when carrying out submarine warfare tasks)
– to destroy torpedoes, attacking the ship (when carrying out anti-torpedo defence tasks)
The complete set of the Paket-E/NK comprises:
– Paket-E control system
– rotating or fixed launching units
– Paket-AE specialized target designation sonar
– combat modules mounted on the launchin unit
Depending on missions assigned to the surface ship, its launching units can house combat modules armed with different combinations of small-sized heat-seeking torpedoes and/or anti-torpedoes, both in nomenclature and in quantity.
The small-sized heat-seeking torpedo is designed to engage enemy submarines, and the anti-torpedo is designed to intercept and destroy attacking torpedoes. Both are housed in unified transport-launch containers.
The Paket-E/NK system can operate independently or be integrated into ship’s antisubmarine/anti-torpedo defence system, solving a number of tasks in fully automatic or automated modes, such as:
– generation of target designation data for small-sized heat-seeking torpedoes, based on data, provided by ship’s sonar systems and posts
– detection and classification of attacking torpedoes, determination of their movement parameters, and generation of target designation data for anti-torpedoes
– pre-launch preparation of combat modules, generation and transfer of firing data to them, launching of anti-torpedoes and/or small-sized heat-seeking torpedoes
– launching units control
The Paket-E/NK system is a radically new weapon system, allowing surface ships to solve ASW/anti-torpedo defence tasks with high effectiveness, and to increase substantially their survivability.
The delivery set of the Paket-E/NK small-sized antisubmarine/anti-torpedo system is customer-defined.
An automated testing and trouble-shooting system can be delivered for combat modules operational support. Source ktrv.ru
