Project 20380 Steregushchy / Project 20382 Tiger Class Corvettes

Project 20380 Steregushchy Class corvettes are the new multirole vessels being built by the JSC Severnaya Verf shipyard and Amur Shipbuilding Plant for the Russian Navy. Steregushchy Class corvettes are intended to replace the Grisha Class corvettes.

Steregushchy Class can be deployed in coastal patrol, escort and anti-submarine warfare (ASW) operations. The vessels can engage surface ships, submarines, aircraft and shore-based targets.

The first corvette in its class, Steregushchy, was laid in December 2001 and launched in May 2006. It began sea trials in November 2006, for commissioning into the Baltic fleet in November 2007.

Steregushchy – Russian Ministry of Defense

The second ship in class, Soobrazitelny, was laid in May 2003 and launched in March 2010. It was delivered to the Russian Navy in July 2011.

Boyky was laid in July 2010 and launched in April 2011 for the commissioning in 2013. Sovershenny was laid in June 2006. It is expected to be launched in 2013 for the commissioning in 2014. Stoyky was laid in November 2006. It was launched in May 2012 for the commissioning in 2013. Construction of the sixth ship in class, Gromky, began in February 2012.

In June 2011, United Shipbuilding Corporation (USC) signed a contract with Russia’s official weapons exporter Rosoboronexport to supply two new Tiger Class corvettes for the Algerian Navy. Tiger Class is an export variant of the Steregushchy Class corvette.

Project 20382 Tiger Corvette

Project-20382 “Tiger” corvette  – navyrecognition.com

Project-20382 “Tiger” corvette is a ship for acting in the near sea zone against ships and submarines, for supporting landing troops, and against air targets. The corvette is equipped with Uran anti-ship missiles. Kashtan antiaircraft missile system, and Ka-27 helicopter. The “Tiger” corvette’s baseline is project-20380 Steregushchy [“Guardian”] corvette, which entered Russian naval forces’ combat strength in 2008. Experts estimateone export “Tiger” corvette at about $120-150 million. Primarily South-East Asian countries, as well as Venezuela and Qatar are interested in the corvette.

A wide range of products of the Russian defence industrial complex is represented at the international exhibition of naval machinery and weapons Euronaval’2004, which opened at Le Bourget near Paris on 24 October 2005. The Russian chief delegate made special note of the latest Project 20382 Tigr corvette, featuring Stealth technology.

In September 2005 Russia named the first potential customers of the corvette Tiger, project 20282. The countries mentioned after IMDS-2005 were India, China, Vietnam, Iran, Indonesia, Kuwait, Algerias, and Egypt. The export version has few differences from the Russian version. It has the same construction and the architecture of the systems. The peculiarity of the ship is that it is built on a module system. This is a totally new principle in the Russian shipbuilding which allows for fast and easy repair and upgrade.

The designer CMKB Almaz suggests different options of the ship. Instead of the Russian 100mm AK-190M it is possible to fit Otto-Melara 76mm. The main ship is to be fitted with four Russian diesels. Two work at cruise speed, two more are switched to gain the max speed of 26-28 knots. Two pair of diesels instead of diesel-turbine give 1.5 times less fuel consumption. German MTU diesels are offered as an option. Zarya-Mashproject gas turbines will also be fitted on some ships. 20380(2) will be able to carry 12 tons helicopter.

After experiencing the Western military equipment embargo, Admiral Slamet Soebijanto turned to the East for possibilities. In September 2005, the Navy Chief of Staff and his team visited Russia to explore the purchase of warships from Rosoboronexport, Russia’s armament industry. The navy’s Strategic Plan for 2003-2013, created by Soebijanto’s predecessor Bernard Kent Sondakh, included the purchase of four Sigma Class corvettes from Holland. The plan was already approved by the House of Representatives (DPR). The four ships were to be purchased in two stages-the first in 2003. The Dutch government provided export credit facilities. The first two ships were currently being constructed and were expected to be ready in 2007.

After the presentation of the project 20382 Tiger Corvette, an export variant of the project 20380 Steregushchiy (Guardian) Corvette, a number of participants of the International Naval Salon held in June 2007 in St. Petersburg, there was some customer interest in it. Rosoboronexport (Russian Defense Export State Corporation) was working actively in this direction and hoped to have some particular contracts by the summer of 2008. Source globalsecurity.org

Steregushchy Class weapons and missiles

Stoikiy – КИНОКОМПАНИЯ ОФИЦЕРЫ ВКС и ВМФ РОССИИ

The Steregushchy Class is armed with a combination of missile systems, including Kh-35 missiles and 3M-54 Klub missiles. One Kashtan anti-aircraft systems on-board provide close-in air defence against anti-ship missiles, aircraft and small surface targets. Beginning from Soobrazitelny, the new ships in class are being armed with the REDUT-K SAM system, in place of Kashtan system.

Kh-35 anti-ship missiles

The KH-35 is a subsonic, anti-ship cruise missile that was originally developed in 1983 by the Soviet Union.[1] It has a two stage, liquid fueled propellant and weighs 480 kg and can be launched from fighter jets, attack helicopters, bombers, and naval surface ships. Its modern variant, the KH-35U, was deployed in 2003 and will be equipped on Russia’s fifth-generation fighter aircraft, the Sukhoi PAK FA.[2] The KH-35U uses inertial guidance with a Glonass Receiver and an active radar seeker to find its target.[3] Russian officials claim that the KH-35U is immune to enemy countermeasures.[4]

Stoikiy – КИНОКОМПАНИЯ ОФИЦЕРЫ ВКС и ВМФ РОССИИ

The claim that the KH-35U is immune to enemy countermeasures, if true, makes it an extremely dangerous weapon, especially when coupled with Russia’s fifth generation Sukhoi PAK FA stealth fighter aircraft. Ultimately, improved air defense countermeasures could enable the KH-35U to strike vessels deep within contested airspace, providing Russia with a substantial advantage on the battlefield. Source missiledefenseadvocacy.org

The ‘Poliment-Redut’ is a naval-based air defense missile system with a vertical launch system for destroyers, frigates and corvettes. They are installed on next-generation ships of the Russian Navy.

Russian warships of the Steregushchiy-class (Project 20380) and the Gremyaschiy-class (Project 20385) corvettes are equipped with the ‘Poliment-Redut’ system. Moreover, this system with a larger number of modules is installed on the Admiral Gorshkov-class (Project 22350) frigates. The system can simultaneously strike 16 targets. Source sputniknews.com

The system boasts four or eight vertical launch systems. It can fire three types of surface-to-air (SAM) interceptors: the short-range 9M100, medium-range 9M96M, and long-range 9M96 missiles.

The 9M100 is a solid-propellant weapon with a range of 10–15 km. and an inertial guidance system with active infrared (IR). The 9M96M is an IR-guided missile with an active radar terminal homing guidance system. Its FRAG-HE 26 kg. warhead travels at a speed of 900m/s and it has a maximum range of 40-50 km.

9M100 short-range surface-to-air missile (SAM)

9M100 missile for naval 9К96 Redut SAM system

The 9M100 is a short-range surface-to-air missile (SAM) being developed by the Fakel Design Bureau, part of Almaz-Antey concern, for new air defenses that should be in place within Russia by 2015. It is targeted at countering the latest generation of fighter aircraft, helicopters, cruise missiles, guided bombs, supersonic missiles and unmanned aerial vehicles (UAVs) which pose a grave threat to ground forces and key facilities. The highly maneuverable 9M100 missile is being designed for launch by means of a vertical launching system (VLS). As of early 2010 the 9M100 missile system is associated with Vityaz medium-range air defense system and might be the primary weapon for the Morfei short-range air defense system.

The 9M100 guidance system combines an inertial navigation system (INS) with an infrared seeker along with a contact and proximity fuze which ignites the warhead. Such a guidance system means that the 9M100 missile is a fire-and-forget weapon capable of engaging multiple targets simultaneously. The solid propellant rocket motor features thrust vectoring control providing outstanding maneuverability.

The 9M96 is a new missile that is resistant to jamming and can intercept targets at a speed of Mach 15 (4,800-5,000 m/s) and at an altitude of 35 km. It can hit incoming threats at a range of 150 km. An active radar homing head and inertial navigation system are used for midcourse guidance. The thrust vectoring control system offers impressive maneuverability at any altitude or range.

9M96M, and long-range 9M96 missiles

The S-400 Triumph also launches 9M96E and 9M96E2 medium range ground-to-air missiles. Designed for direct impact, the missiles can strike fast moving targets such as fighter aircraft with a high hit probability. The maximum range of the 9M96 missile is 120km.

The SAM is equipped with a directed explosion warhead to improve the chances of fully destroying fast moving and agile targets upon direct impact. The hit probability is 0.9 against aircraft, 0.8 against drones, and 0.7 against missiles. Thrust vectoring makes it possible to achieve high Gs and angular rate capability.

A datalink from the MFMTR X-band radar blast is used for midcourse guidance. Its 24 kg. fragmentation warhead produces a controlled pattern. A radar fuse controls the warhead’s timing.

The 9M96 missile was initially developed for the S-400 Triumf ground-based air-defense system that has already been delivered to China. It will soon be sent to Turkey. India, Saudi Arabia, and Qatar are also quite interested in this system.

The three vertical-launched, solid-fuel, one-stage missiles have a variable range of 1-150 km. at an altitude of 5 m. to 30 km. At a speed of 2,100 m/s they can hit targets traveling at 1000 m/s. A Poliment-Redut-equipped frigate can carry 32 medium/long-range or 128 short-range missiles. Any combination is possible — one launcher can house either one medium- or long-range weapon or four short-range SAMs. The four-faced phased array antenna can track 16 targets at once. The detection range is 200 km. Russian sources report that the system can engage surface targets as well.

Boikiy – T24

The combination of various-range missiles makes it possible for one Poliment-Redut to carry out the missions of three air-defense systems. It provides multi-tier defense, reducing reaction time. It can fire at a rate of one launch per second. The vertical start is an important advantage, enabling the system to counter a target approaching from any direction. These highly agile missiles can use an optimal trajectory to kill highly maneuverable threats. Source strategic-culture.org
