Karakurt Project 22800 Corvette to Give Russian Navy Extra Punch

The Russian Project 22800 (Karakurt-class) missile corvette, named Typhoon, is to be launched in November at the shipbuilding company Pella in St. Petersburg. It will enter service in 2018. The first corvette of this class, Uragan, was launched in July 2017 and is also to enter service next year. A total of 18 Karakurt-Class corvettes are to join the Black Sea, Northern and Pacific operational fleets by 2022.

The corvette is designed to conduct anti-surface and anti-air warfare, as well as coastal surveillance missions in littoral zones. It features a stealth superstructure housing an integrated mast mounted with phased array radar panels. The modular design makes it possible to meet mission-specific requirements. Then vessel boasts advanced command and control systems, navigation and communication facilities, as well as state-of-the-art weapons. 

The Project 22800 measures 67m-long and 11m-wide. Range: 2,500nmi. Displacement: 800t. Maximum speed: up to 30 knots. Endurance: 15 days.

M507 is an engine consisting of two 56-cylinder diesel units (diesels), each of them works for its own shaft. The units are connected with each other by a main gearbox, which transmits rotation of crankshafts of the units to the power takeoff flange. Among the main advantages of the model are the integrated reverse reduction gearbox, compact design and low weight along with high output (7355 kW).

The relatively small ship capable of being operational both in the littoral zone and offshore maritime zone boasts a powerful punch. The armament suite includes Kalibr-NK sea-to-surface cruise missiles and the P-800 Onyx medium-range anti-ship missile fired from an eight-tube UKSK vertical launching system (VLS). The 3S13 launcher allows using both. Kalibr-NK is a subsonic (Mach 0.8.) inertial guidance land attack weapon deployed by the Russian Navy. Its range is 1,500–2,500 km. The missiles have been fired against terrorist targets in Syria. Armed with Kalibr, the corvette can strike almost any target in Europe. 

The supersonic P-800 Yakhont’s firing range reaches 300km when flying along a combined trajectory and 120kg when following only a low-altitude trajectory. Flight speed varying over the range from M-2.0 to M-2.5 is provided by the kerosene-fueled multi-mode liquid-fuel ramjet. The closest American counterparts, the Tomahawk and Harpoon missiles, are subsonic; the best French antiship missile, the Exocet, has a range of only 45 miles.

The AK-176MA 76.2mm automatic gun is mounted on the forward bow deck. It can fire at a rate of 150rpm and can engage targets within the maximum range of 15km. Number of rounds for automatic firing: 152. Housed in a multifaceted turret to deflect electromagnetic waves, the gun integrates a digital control system and Sfera-2 optronic station to acquire multiple targets at long ranges.

The corvette is armed with Pantsir-M – a naval variant of the Pantsir-S1 combined surface-to-air missile (SAM) and anti-aircraft artillery system. The system can track and attack up to four targets at a time. The hitting range of the Pantsir-M system varies from several dozen meters to 20 kilometers. 

Pantsir-M carries up to twelve 57E6 or 57E6-E two-stage solid fuel radio-command-guided surface-to-air missiles in sealed ready-to-launch containers. They are arranged into two six-tube groups on the turret. The missiles are not fitted with seeker to keep target engagement costs low. Instead high-precision target and missile tracking is provided via the systems multiband sensor system and guidance data is submitted via radio link for up to four missiles in flight. Two missiles could be fired at one target to make the kill more reliable. The 57E6 missile is believed to have a hit probability of 70-95% and have a 15-year storage lifetime in its sealed containers. 

Pantsir-M can counter aerial and surface targets with two six-barrel AK-630M 30mm close-in weapon systems (CIWS), which can also strike floating mines and shore-based fire posts. With a rate of fire of up to 5,000rpm, AK-630M can engage targets within the range of 5,000m. It includes two GSh-6-30K / AO-18KD 30mm six-barrel guns. The automatic gun employs a circuit of multi-barrel weapons with a cluster continuously revolving during firing. The automatic mechanisms operate due to the energy of powder gases evacuated from the barrels. Firing is controlled remotely.

An advanced air radar is capable of acquiring aerial targets at a range of about 100 km. MINERAL-ME shipborne radar system features automated reception and processing of surface surveillance data collected from external sources (ships, helicopters, observation posts). The system operates in active and passive modes. It provides for mutual data exchange, navigation and joint combat operation control station. Active detection for surface destroyer-class targets: 250km. Passive radar detection for emitting radar systems: 80-450 km (depending on frequency). 

MR-123 radar system (LASKA) is designed to monitor surface/air situation and to control fire of 30mm-76mm close-range shipborne artillery systems against air/missile and small-size surface targets. SP-520 Electro-Optical Naval Artillery Fire Control System (SP-520 CS) is designated for target search and tracking, both autonomous and based on target designation, naval artillery gun and MLRS salvo fire control.

PK-10/PU KT-216 Shipborne Decoy Dispensing System protects the ship against radar – or electro-optical guided weapons. The PK-10 dispenses decoys in close vicinity of the ship, whose signatures are greater than those of the corvette. As a result, the homing system of an attacking missile either loses track of the ship or is seduced by a decoy.

The new Russian missile corvette Karakurt (project 22800) packs a formidable arsenal, including multipurpose missile launchers, automatic cannon, an air-defense missile system and powerful electronic-warfare systems. The ship features high maneuverability, increased sea-going performance, and stealth technology to give the Russian Navy an extra punch.
