Project 20381 Soobrazitel’niy Corvette

The Steregushchy class (Russian: стерегущий – “vigilant”) is the newest class of corvette in the Russian Navy. It was designed by the Almaz Central Marine Design bureau. The first ship was designated Project 2038.0 (or 20380) by the Russian Government; subsequent vessels were built to an improved design, Project 20381. At 2,200 tons it is large for a corvette and is designated as a frigate by NATO. Project 20382 “Tigr” is an export variant that has been ordered by Algeria. Project 20385 another one variant .

Project 20380 Steregushchy Class: Details

First ship was designated Project 2038.0 (or 20380) Steregushchy class (530)

This type has been further developed into the Gremyashchy-class corvette.

Stoikiy (545) Project 20381 Soobrazitel’niy Corvette

The ships of the Steregushchy class are multipurpose corvettes, designed to replace the Grisha class. Such ships are used for littoral zone operations, engagement of enemy submarines and surface ships, and gun support of landing operations. The first batch being built at the Severnaya Verf shipyard in St. Petersburg consists of four ships. A second building line has been started at Komsomolsk. The lead ship of this second batch will be named Sovershennyy. The Russian Navy has publicly announced that they expect to buy at least 30 of these ships, for all four major fleets.

In 2007 the Indonesian Navy made an agreement in principle (pending a full contract) for four vessels of this type to replace their ageing Dutch-built Fatahillah-class corvettes. The first was to be built in Spain and fitted out in St. Petersburg, leaving open the option of Indonesian involvement in building the subsequent ships. This agreement appears to have lapsed; in 2011 Indonesia signed a deal for two Milgem-class corvettes from Turkey. Rosoboronexport have briefed Singapore and the United Arab Emirates on the vessel.

Steregushchiy (530)

The first actual contract for the export version, Project 20382 Tigr, was signed at the 5th International Maritime Defense Show in St. Petersburg in July 2011 when Algeria ordered two ships. The cost was estimated at US$120–150 million per ship. One will be delivered in 2014 and one in 2015

They have a combined bridge and command centre, and space and weight provision for eight SS-N-25 missiles. Stealth technology was widely used during construction of the ships, as well as 21 patents and 14 new computer programs. Newest physical field reduction solutions were applied too. As a result, designers considerably reduced the ship’s radar signature thanks to hull architecture and fire-resistant radar-absorbent fiberglass applied in tophamper’s design.

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

A-190E 100mm main gun

A-190E 100mm main gun controlled by a 5P-10E system that can track four targets simultaneously

The Burevestnik A190, also referred to AK-190 and A-190, is a lightweight shipboard 100mm single-barrel, multi-purpose, automatic naval gun designed to engage surface ships, airborne and coastal targets. The gun system can be installed on frigates, patrol and missile boats with a displacement above 500 tons and features two ammunition feed systems one on each side. It can fire High Explosive (HE) projectiles with impact fuze and Anti-Aircraft (AA) projectiles with time fuze. An automatic command and control system enables a fast response (2-to-5 seconds) to incoming threats as well as makes possible practice without activating the 100mm gun. The turret offers a coverage of +/-170-degree in azimuth and -15-degree to +85-degree in elevation. Somehow the A190 is the successor to the 76.2mm AK-176M naval gun system. The A190E mount includes a magazine with 80 projectiles. This naval guns system provides a maximum rate of fire of 80 rounds per minute and can engage targets at ranges of up to 20 kilometers.

The A190E entered service with the Russian Navy’s Bora class attack crafts in 1997 and the Indian Navy’s Talwar class frigates in 2003.  Source

5P-10E Radar Control System

2 x AK 30m CIWS

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.

1 x Kashtan CIWS (Project 20380 only) 

Kashtan CIWS (Project 20380) 

The command module detects and tracks threats, distributes targeting data to the combat modules, and interrogates IFF of approaching threats. The command module has a 3-D target detection radar, and an all weather multi-band integrated control system. Depending on the number of installed combat modules, the system can engage multiple targets simultaneously. The combat modules automatically track using either radar, electro-optronic control system (such as FLIRs) or both, and then engages targets with missiles and guns. The combat modules are typically equipped with two GSh-30K (AO-18K) six-barrel 30 mm rotary cannons, fed by a link-less feeding mechanism, and two 9M311 launchers equipped with 4 ready-to-fire missiles each and fed by a reloading system storing 32 missiles in ready-to-launch containers.

The guns used in the Kashtan are the GSh-30K six-barrel 30 mm rotary cannon. Individually, each GSh-30K has a higher rate of fire compared to other guns used by other CIWS such as the GAU-8 on the Goalkeeper and the M61 Vulcan on the Phalanx. Along with a high rate of fire, the fairly heavy round (390 g or 14 oz) used by the Kashtan is comparable to the DPU rounds of the GAU-8 Avenger (425 g or 15.0 oz), although the muzzle velocity (and therefore both the kinetic energy and effective range) is slightly lower, partially offsetting the high caliber and rate of fire.

The missiles used in the Kashtan are the 9M311 missiles, which is also used on the 9K22 Tunguska. The 9M311 is a SACLOS guided missile, however, it is steered automatically by the command module. The warhead weighs 9 kilograms (20 lb) and is either laser or radio fused. The warhead is a continuous-rod warhead with a steel cube fragmentation layer. The detonation of the warhead will form a complete circle of fragmentation that is 5 meters in radius, and damage or destroy anything in that circle. Source
