The Stereguschiy class corvettes are the new multirole warships being built by the Severnaya Verf shipyard and Amur Shipbuilding Plant for the Russian Navy. Russian Navy planns to build 12 vessels of this class from which 4 warships are currently active. More Stereguschiy class corvettes are planned to be commissioned within the next 3 years.
The lead vessel was commissioned in 2007, 2nd in 2011, 3rd in 2013, and the 4th one in 2014. More of these warships are expected to join within next 3 years.
The Stereguschiy class ships has stealthy design which significantly reduces the radar signature. The acoustic, infra-red, magnetic and visual signatures were also reduced by incorporating the stealth technology in the construction of the warships. These vessels have a length of 105 meters, width of 13 meters and can reach a maximum speed of 27 knots. It can complement 100 personnel, including helicopter maintenance crew.
These corvettes are basically used for coastal patrol, anti-submarine warfare, escort, and anti-shipping duties. Vessel are fitted with advanced radars, anti-ship missiles, surface-to-air missiles, and torpedo launchers.
For anti-ship role it has two quadrupple launchers with Kh-35 (Western designation AS-20 Kayak) anti-ship cruise missiles. These missiles can hit a target at a range of up to 300 km.
The first Stereguschiy class ship was fitted with Kashtan Close-In Weapon Systems (CIWS), however all further ships are fitted with a 12-cell Redut-K Vertical Launch System (VLS) in place of the Kashtan. This VLS is a naval version of the S-350E Vityaz land-based air-defense system. It fires medium-range air defense missiles. Last ditch defense against incoming anti-ship missiles is provided by two 30 mm six-barreled AK-630M CIWS. These mounts can fire up to 5 000 rounds per minute each for a maximum range of 5 km.
The main gun fitted forward is an Arsenal A-190 100 mm naval gun which has range over 20 km.
For anti-submarine role there are two quadrupple launchers with 330 mm torpedo tubes for unique Paket-NK torpedoes. These can engage both enemy submarines, as well as incoming torpedoes, thus serving a dual role.
These warships have hangar for a single Ka-27 helicopter, which can be used for reconnaissance and anti-submarine missions.
Primary radar has a range of up to 150 km. The countermeasures equipment includes a TK-25E-5 countermeasures system and PK-10E decoy system.
The Stereguschiy class has four 16D49 Diesel engines, that develop a combined power output of 23 320 shp. The propulsion system provides a maximum speed of 27 knots and a cruising range of 7 400 km (4 000 nautical miles) at 14 knots. The Steregushchiy class has a sea endurance of 15 days.
Variants
Tigr (tiger) class corvette. In June 2011, United Shipbuilding Corporation (USC) signed a contract with Russia’s official weapons exporter ROSOBORONEXPORT to supply two new Tigr class corvettes for the Algerian Navy. Tiger class is an export variant of the Steregushchiy class. The Tigr class carries either eight supersonic Yakhont (SS-N-26) anti-ship cruise missiles or sixteen subsonic Kh-35E Uran (SS-N-25 Switchblade). It also has two twin-tube launchers for 533 mm heavy torpedoes.
Gremyaschiy class corvette. It is a follow-on project to the Stereguschiy class with greater dimension and diplacement. These have improved habitability for higher endurance missions. These warships were developed for the Russian Navy. The lead ship, Gremyaschiy, was laid down in 2011 and commissioned in 2015. The second ship of the class, Provorniy, was commissioned in 2016. However these corvetted were designed with German MTU diesel engines. Because of sanctions imposed on Russia due to annexation of Crimea and military involvement in Ukraine deliveries of these engines for follow-on ships were stopped. This resulted in the cancellation of further units. The Russian Navy ordered more Stereguschiy class corvettes instead of the Gremyaschiy.
