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 two were designated Project 2038.0 (or 20380) by the Russian Government; subsequent vessels were built to an improved design, Project 20385. 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 sold to Indonesia and Algeria.

This type has been further developed into the Gremyashchy class corvette

Programme

The ships of the Steregushchy class are very large multipurpose corvettes, designed to replace the Grisha class. 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 where orders for at least a further two ships are expected. The lead ship of this second batch will be named Sovershenny. The Russian Navy has publicly announced that they expect to buy at least 30 of these ships, for all four major fleets.

According to Jane's Naval Forces News, the first vessel was commissioned on 14 November 2007.

Export

The first contract for the export version, Project 20382 Tigr, was signed at the 5th International Maritime Defense Show in St. Petersburg when Algeria ordered two ships. The cost was estimated at US$120–150m/ship.

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. Rosoboronexport have briefed Singapore and the UAE on the vessel.

Design

The Steregushchy-class corvettes have a steel hull and composite superstructure, with a bulbous bow and nine watertight subdivisions. They have a combined bridge and command centre, and space and weight provision for eight SS-N-25 missiles.

The Kashtan CIWS on the first two ships was replaced in subsequent vessels by 12 Redut VLS cells containing 9M96E medium-range SAMs of the S-400 system. SS-N-27 (3M-54 Klub) cruise missiles will be fitted to a larger domestic version, Project 20385 starting with the sixth vessel, Provornyy, although 20385 is the name sometimes applied to all ships with the Redut.

The export version known as Project 20382 Tigr carries either eight supersonic SS-N-26 (P-800 Yakhont) anti-shipping missiles or sixteen subsonic SS-N-25 'Switchblade' (Kh-35E Uran). It also carries two twin-tube launchers for 533mm heavy torpedoes. The A-190E 100mm gun first used in the Talwar class frigates is controlled by a 5P-10E system that can track four targets simultaneously. Protection from air attacks is provided by the Kashtan CIWS and eight mounts for the SA-N-10 'Grouse' (9K38 Igla) SAM.

Operational history

Steregushchiy started sea trials in November 2006 and was commissioned in the Baltic fleet on 14 November 2007. The second vessel in the class, the Soobrazitelnyy, was launched in 31 March 2010 and is expected to start sea trials in November/December 2010.
