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 Tigr-class corvette showcased at Euronaval 2016: Here
Among the most advanced surface combatants are the Project 20382 Tiger-class corvette with the Club-N integrated missile system and vertical launchers, Project 22356 and 11356 frigates being currently supplied to India, Project 22460 offshore patrol vessel, Project 21632 Tornado-class missile ships and their derivatives armed with missile systems. It is expected that foreign navy representatives will take interest in the Amur-1650 and Project 636 non-nuclear submarines equipped with guided missile weapons.
The main missions include protection of territorial waters, exclusive economic zone, continental shelf, offshore areas, naval bases and ports. The Steregushchy class can be deployed in coastal patrol, escort and anti-submarine warfare (ASW) operations, as well as to support amphibious assaults. The corvette can engage surface ships, submarines, aircraft and shore-based targets.
The ship is not an upgrade. The project has been developed practically from scratch by the Almaz Central Marine Design Bureau with over 21 inventions patented and 14 certificates issued for registration of computer programs.
It uses stealth technology. The Steregushchiy-class corvettes have a steel hull and composite material superstructure. The ship’s radar signature is reduced thanks to hull architecture and fire-resistant radar-absorbent fiberglass applied in tophamper’s design.
The modular design allows for space-efficient integration of weapon systems and/or replacement by alternative weapon systems. Source strategic-culture.org

Steregushchy Class design features
Steregushchy (530) – Image: shipmodels.info
Steregushchy Class was designed by the Almaz Central Marine Design Bureau. The corvette incorporates a steel hull, composite superstructure and a bulbous bow. The hull is divided into nine watertight subdivisions.
The stealthy design significantly reduces the radar signature of the ship. The acoustic, infra-red, magnetic and visual signatures were also reduced by incorporating the stealth technology in the construction of the warship.
Steregushchy Class has an overall length of 105m, width of 13m and draft of 3.7m. Full load displacement of the ship is 2,100t. The vessel can sail at a maximum speed of 27kt. It can complement 100 personnel, including helicopter maintenance crew.
Corvette command and control systems
The Steregushchy Class features Sigma combat information management system. The system collects information from the radars and sensors and provides real-time situational awareness. It also allows the ship to exchange intelligence information with other naval units in the battle-group.
Steregushchy Class weapons and missiles
The Steregushchy Class is armed with a combination of missile systems, including Kh-35 missiles and 3M-54 Klub missiles. Two 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-35E (3M-24E) anti-ship missile is designed to destroy surface warships displacing up to 5,000 tonnes, as well as seagoing transports.
The Kh-35E unified guided missile can be launched from the following platforms:
– Uran-E type ship-borne missile systems;
– Bal-E type mobile coastal missile systems;
– tactical and naval combat aircraft.
The Kh-35E anti-ship missile can be employed in fair and adverse weather conditions at Sea States up to 5-6, by day and night, under enemy fire and electronic countermeasures.
The Kh-35E’s aerodynamic configuration is optimized for high subsonic-speed sea-skimming flight to ensure stealthy characteristics of the missile.
Target acquisition and designation data can be fed into missile’s guidance system from both ship-based and external target data sources.
The missile has low signatures thanks to its small dimensions, sea-skimming capability and a special guidance algorithm ensuring highly secure operational modes of the active radar seeker.
Its ARGS-35E active radar seeker operates in both single- and multiple-missile launch modes, acquiring and locking on targets at a maximum range of up to 20 km.
Missiles, employed in ship-based and land-based missile system, are delivered in sealed transport-launch containers. This ensures proper level of reliability of the system in harsh climatic conditions and low maintenance man-hours required for its servicing on carriers.

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.
