The corvette Gremyashchiy, with hull number 337, is the lead ship of her class with the same name

Introduce

The Gremyashchiy-class, as the first member of the 20385 project, this corvette was developed by the Almaz Central Marine Design Bureau in Saint Petersburg. The ship was laid down on May 26, 2011 and the official laying down ceremony took place on February 1, 2012.

Gremyashchiy-class corvettes are very large multipurpose vessels, designed to complement the Steregushchiy class already being commissioned with the Russian Navy. They have been designed to have an improved habitability for higher endurance missions, and are able to launch cruise missiles.

Design

Project 20385 is larger in size and displacement than its predecessor. The ship has a displacement of 2,500 tons, a length of 106m (347.8 ft), a beam of 13m (42.7 ft) and a draft of 5m (16.4 ft).

Compared to its predecessors, the ship lacked aft mast above the helicopter hangar, and single integrated mainmast that no longer includes separate open shelves for artillery and navigation radars.

Sensor and Electronic system

The Project 20385 corvette is designed for strike missions and anti-submarine warfare. She features powerful strike weapons and modern electronic warfare systems.

The ship is equipped with the multi-purpose AESA naval radar “Zaslon”. Fire control is through the Ratep 5P-10E Puma system. Sonar facilities are managed through the bow-mounted Zarya-ME and the towed Vinyetka. The GORIZONT-25 suite is provided for navigation. TK-25E-5 forms the Electronic Warfare section, and countermeasures are 4 x PK-10 launchers.

Propulsion

Gremyashchiy is equipped with a Combined diesel and diesel propulsion system, driving 2 shaft, including 4 Kolomna 16D49 diesel engines, generates an output power of 12,000hp.

The ship can reach a top speed of 27 knots, a range of 4,000 nmi at a speed of 14 knots. She can accommodate a crew of 99 men.

Armament

Gremyashchiy is armed with a 100 mm A-190 Arsenal naval gun in the bow, to engage enemy surface ships, coastal and air targets. With a rate of fire of 80rpm, the weapon can travel to a distance of 20km.

The vessel is equipped with a UKSK VLS system comprising eight launchers for either Kalibr, Oniks or Zircon anti-ship missiles. The missiles can protect against surface and shore-based targets at ranges up to 300km.

The Redut VLS system with 16 launchers has been placed on the stern, which uses a number of 9K96 surface-to-air missiles to defend air targets.

The close-in weapon system is two 30mm AK-630M, to defend against aerial threats. The onboard Paket anti-submarine system provides self-defence for the vessel against enemy submarines and torpedoes.
