Gromkiy, hull number 335, is part of modern Steregushchiy-class corvettes of the Russian Navy, which entered service in 2018.

Gromkiy 335 is a Project 20380, specially built for the Pacific Fleet within the framework of the rearmament program of the Russian Navy. The ships of this project, developed by the Almaz Central Marine Design Bureau, are dedicated to carrying out operations in the near-shore area against enemy surface ships and submarines, which can be operated either solo or combined in a fleet.

The characteristic feature of the project 20380 corvette is its ability to minimize radar, noise and visual signatures to the fullest extent thanks to stealth construction. Gromkiy 335 has a length of 104.5m, a beam of 11.1m, a draft of 3.7m with a displacement of 2,200 tons.

Gromkiy has a steel hull and a superstructure made of composite material, with a bulbous bow and nine watertight subdivisions. She has a bridge and a combined command center, hull architecture and fire-resistant radar-absorbent fiberglass applied in the design. As a result, designers considerably reduced the ship’s radar signature.

Another feature of this ship is that she has a low stern, a gentle bridge that leads straight to the helicopter deck and hangar. This is a privilege for ships of the destroyer class and above, but the Russian corvette is able to do this thanks to its optimal design to carry Ka-27PL helicopters. In order to save space on the ship, the designers abandoned a linear arrangement with a combination of offensive weapons that placed them horizontally-cross. Such a layout has proven successful on similar warships of the US, South Korea, China and Japan.

Gromkiy’s propulsion system is a diesel-electric arrangement driving 2 shafts. The four 16D49 diesel engines provide a total of 24,000 horsepower, while generating 2,520 kiloWatt of electricity for onboard operations. The ship can reach a maximum speed of 27 knots, with a range of 4,000 nautical miles at a speed of 14 knots. The corvette’s crew, consisting of more than 100 men.

Gromkiy’s basic offensive weapons are two large launchers with a combination of Uran missiles, each platform carries four all-weather Kh-35 anti-ship missiles. Each missile is capable of sinking surface ships with a displacement of up to 5,000 tons. The capability of the Uran subsonic missile is at least equal to the famous Kalibr cruise missile in terms of operational range. The main close range weapon of the Steregushchiy is the 100mm A-190 cannon at the bow of the ship. The cannon can fire at a rate of 80 rounds per minute, effective range is 20km. The corvette is also equipped with two AK-630M close-in weapon systems, installed near the stern. These guns fired 5,000 rounds per minute to a maximum effective range of 5,000m, they could deal with both surface ships and air targets at close range.

In addition, the ship is also equipped with two quadruple torpedo tubes for the technologically revolutionary Paket-NK anti-torpedo missile. To counter enemy torpedoes, Russia uses controlled jet torpedoes. The Paket-NK system reduces the risk of a corvette being hit by enemy torpedoes by a factor of three. For attacks on enemy submarines and surface ships there are Malyshka torpedoes, which can accelerate to 50 knots, destroying targets at distances of up to 20 km.

Gromkiy was laid down on February 17, 2012, and launched on July 28, 2017. The ship is expected to make a positive contribution to the power of the modern Russian Navy.
