New Project 23420 Small Anti Submarine Warfare Ship


Wednesday, 17 February 2016 10:21

Russia’s Almaz Central Marine Design Bureau (member of United Shipbuilding Corporation OCK) unveiled the new Project 23420 small anti submarine warfare (ASW) ship. The vessel features a futuristic design with very sleek lines.

According to Almaz, the small ASW ship is designed for conducting combat operations against underwater, surface and air adversaries, for guarding naval bases, for engaging enemy shore installations with artillery fire, for patrolling the state sea border and EEZ.

The Almaz Central Marine Design Bureau, founded in 1949, is a leading design and engineering organization in the Russian shipbuilding industry, unique by its range of designs and their complexity. The Almaz CMDB today is the leading Russian designer of high-speed craft, small and medium size surface combatants, landing air cushion vessels, mine countermeasures vessels, special purpose vessels and floating docks.


The Project 23420 ship displaces about 1300 tons for a length of 75 meters. Its endurance is 15 days at sea with a range of 2500 nautical miles and a crew of about 60 sailors.

There are two types of propulsion systems available: diesel or diesel-electric propulsion with fixed pitch propellers or diesel-gas turbine propulsion with variable pitch propellers.

Version 1 Version 2
1 x diesel or diesel-electric propulsion 1 x diesel-gas turbine propulsion
2 x fixed pitch propellers 2 x controllable pitch propellers

Version data

Project 23420 systems:


1 x 76-mm AK-176MA gun (152 rounds) or
1 x 30-mm AK-306 gun (500 rounds)

76-mm AK-176MA gun


The need for a lightweight 76 mm (3″) gun for small combatants prompted the development of this weapon.  The result was a fully automatic weapon using the same gun barrels as used for the 76.2 mm (3″) AK-726 mount A-221.  The trials were performed in 1977 and in 1979 the gun was accepted into production.  The mount was produced in Gorky and was used on virtually all small combatants built in the 1980s.

This mount has selectable rates of fire of 30, 60 and 120-130 rounds per minute.  The highest speed could be achieved by firing a burst of 75 rounds, but afterwards the gun had to cool off for 25 to 30 minutes.   This weapon is considered effective against missiles and during trials it consistently shot down Falanga ATGMs (AT-2 Swatter) simulating Harpoon ASMs.  On average it took 25 rounds per missile.

The gun is controlled by the MP-123-02 FCS.  This system uses radar, TV and laser designators.  This fire control system has a range of 28 miles (45 km) without ECM and 18 miles (30 km) with ECM and weighs 5.1 tons (5.2 mt).

Uses a monobloc barrel with a casing and a vertical sliding breech block.  Automatics are recoil operated.  The barrel is sea-water cooled, which is pumped between the casing and barrel at 11.5 fps (3.5 mps).

Some of these guns have been sold to the People’s Republic of China.

Nomenclature note:  This gun is classified as 76 mm/60 but the actual bore diameter is 76.2 mm (3.0″) and the actual barrel length is 59 calibers.

30-mm AK-306 gun


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. 

AO-18LAO-18L (for AK-306):  341.7 lbs (155 kg) 

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.

3M-47 Ghibka gun ring


The 3M-47 Ghibka turret was designed by Altair Naval Radio Electronics Scientific Research Institute and is manufactured by the Ratep Joint Stock Company. 

Ghibka 3M-47 (3M47 Gibka) Turret Mount is intended for guidance and remote automated launching of IGLA type missiles to provide protection of surface ships with displacement of 200 tons and over against attacks of anti-ship missiles, aircraft and helicopters in close-in area..


The turret mount utilizes information from ship’s radars. The missiles are equipped with homing head with optical tracking (passive) and artifical thermal noise detector. The system is design to resist natural (background) and artificial jamming conditions. The turret mount is equipped with 9M39 and 9M342 anti-aircraft guided missiles. 

To date, 3M-47 Ghibka is installed on Project 21630 “Buyan” class corvettes, Project 21631 “Buyan-M” class missile corvettes and will be installed on the future Mistral type LHD for the Russian Navy.

1 x Paket-E/NK system (2 x launchers, 8 x torpedoes) or
1 x RPK-8E system (1 x RBU-6000, 48 x 90R ASW missiles and RGB-60 depth bombs)

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.

DP-64 grenade launcher is designated for protection of submarines in the above-water position, ships at external roadsteads, against attacks of underwater combat swimmers.

The grenade launcher allows carrying out loading and fire conducting by one person at a range of up to 400 m.

Firing the grenade launcher is conducted with FG-45 fragmentation grenade to destroy a swimmer and with SG-45 signal to mark the swimmer’s location.

DP-64 grenade launcher allows conducting fire ordinary small arms from any place of the ship deck, from the deck house of a submarine in the above-water position and from a helicopter.


1 x Gorizont-AIR-S-100 unmanned aerial vehicle suite (2 x UAVs)

Gorizont-AIR-S-100 unmanned aerial vehicle


The Schiebel S-100 Camcopter is a Vertical Takeoff and Landing (VTOL) UAS in use in several navies. The system has an endurance of over six hours at a speed of 55 knots carrying 75 lbs of payload. The Camcopter’s diminutive size and payload makes it ideal for sea-based intelligence, surveillance, and reconnaissance from smaller naval ships such as offshore patrol vessels.

In June 2013, Schiebel announced that it was upgrading the aircraft to integrate maritime radar, electronic support measures (ESM) and EO/IR sensors into the S-100 system.

The UAV flies with the French Navy and possibly China’s People Liberation Army-Navy. A variant called the Gorizont Air S-100 produced in Russia under license from Schiebel reportedly serves with the Russian Coast Guard.
