Project 20385 Gremyaschy class corvette

Project 20385 (20380M) has been developed by the Central Marine Design Bureau "Almaz" on the basis of already being mass-produced in the fleet ships of "Guarding" 20380 with the current requirements and operating experience. From predecessors, the new ship differs increased to 2,200 tons displacement and size. Its length will be 105 meters, width - 13 m, draft - about 8 meters.

After putting into operation 5 ships of the project 20380, it was decided to change the composition of weapons. In the new design, the ships of the project, like their predecessors, were also considered ships of the 2nd rank, designed for action in the near sea zone. New ships were supposed to replenish the composition of the Pacific Fleet, in which at that time there was only a corvette "Perfect" - the ship of the basic project 20380.

The Steregushchy and Gremyashchy class corvettes can be used against enemy surface ships, submarines and aircraft, and provide naval gunfire support for shore operations. The Gremyaschy class corvette has a displacement of 2,200 metric tons, maximum speed of 27 knots, operating range of 4,000 nautical miles and a crew of 100.

The ship's armament initially included Uran-E 3M24 (SS-N-25 Switchblade) anti-ship cruise missiles, a 100-mm gun, a variety of air defense and anti-submarine systems and a Ka-27 Helix anti-submarine helicopter. Advanced stealth technology is used to reduce the ship's radar signature, as well as its acoustic, infrared, magnetic and visual signatures, according to the shipbuilder.

Combat power of the modernized craft greatly enhanced by introducing into the arms of a new universal missile complex "Caliber-NK" (instead of anti-ship complex "Uran") with a uniform 8-cell launcher for several types of missiles - anti-shooting and coastal targets. Anti-aircraft weaponry corvette enhanced anti-aircraft missile system, "Red", 9M100 and 9M96 missiles (supplied from 16 to 64 missiles). Artillery weapons - a 100-mm artillery mount A190-01, two 30-mm AK-630M, anti-submarine - a set of "Package". On the ship is provided basing anti-Ka-27PL.

An important feature of the new ship - the presence of so-called "optronic mast", which includes radar systems and systems for various applications, greatly increasing the possibility of corvettes for the detection and tracking of air and sea targets of the enemy, their defeat. In particular, the mast is allowed to refuse a single antenna station fire-control radar "Puma". Significantly improved main power plant, diesel DDA12000 diesel unit was to be replaced by the MTU installation.

The Project 20385 class is a derivative of the Steregushchy class (Project 20380) corvette, featuring better electronics, air defenses and extended operational range, the shipbuilder says. The Steregushchy and Gremyashchy class corvettes can be used against enemy surface ships, submarines and aircraft, and provide naval gunfire support for shore operations.

The Gremyaschy class corvette has a displacement of 2,200 metric tons, maximum speed of 27 knots, operating range of 4,000 nautical miles and a crew of 100. The ship's armament includes Uran-E 3M24 (SS-N-25 Switchblade) anti-ship cruise missiles, a 100-mm gun, a variety of air defense and anti-submarine systems and a Ka-27 Helix ani-submarine helicopter.

Advanced stealth technology is used to reduce the ship's radar signature, as well as its acoustic, infrared, magnetic and visual signatures, Severnaya Verf claims. Composite materials developed and created by Russian specialists of Prometheus Federal State Unitary Enterprise were used to construct the hull and main superstructures on the Gremyashchy, the lead ship of the project 20385. The technology has confidently been tested during the construction of ships of the base project 20380. Superstructure Corvette is made of composite material, which is a non-combustible multilayer plastic. The basis of the material is carbon fiber with high strength characteristics. The innovation of the solution lies in the fact that a ship of this size, made using fiberglass, is 2-3 times lighter than a similar structure made of steel. Another strong argument in favor of this technical solution is the low radar visibility of the superstructure.

In the improved version of the corvette, the designers paid more attention to improving the seaworthy qualities of the combat ship. The new corvette has a better roll resistance and is able to successfully perform combat missions in waves of up to 5 points. The hull of the ship and the island of the superstructure have a reduced by 3 times the rate of circular dispersion of the radar background, which in turn significantly increases the survivability of the ship in combat conditions.

The corvette 20385 planned to replace the 2028 had an enhanced weapon composition and more powerful electronic weapons, the basis of which was the multifunctional radar system from Zaslon JSC. He also had 16 launch cells in the Redut anti-aircraft missile launcher instead of 12, and one 3C-14 eight-shot launcher, with which it was possible to launch a wide range of guided missiles, including missile defense systems and missiles of the Caliber family.

However, since 2013, strange things began to happen in the system of domestic shipbuilding. The Navy refused to continue the 20385 series. Today, there is a conviction in society that the reason was the inability to receive imported MTU diesel engines and gearboxes due to sanctions. In practice, information on the cessation of construction of 20385 was voiced in the media before the Ukrainian crisis. Information sources complained about the high cost of the resulting corvette. The groundwork for the canceled 20385 corvettes in the form of an integrated tower-mast structure installed on the last four corvettes under construction of project 20380, which increased their cost even more.

The ships of the project 20380 were designed with the latest technology using stealth technology. Their superstructures are made of multilayer composite materials, which seriously reduced the radar signature. The underwater part of the hull received contours that made it possible to reduce water resistance at a speed of about 30 knots by about a quarter. Due to this, the ship became faster by 1.5 - 2 knots.

The corvettes are armed with the Uranus anti-ship missile system with launchers for X-35 missiles with a firing range of up to 260 km, as well as a universal 100-mm artillery mount A-190 with a firing range of 21.3 km and a rate of fire up to 80 rounds per minute. To protect them from air attacks, they will be equipped with the Redut anti-aircraft missile system. Now it is the most powerful air defense system that is equipped with naval ships. It can simultaneously strike 16 targets at a distance of 400 km. Its tactical and technical characteristics may be in demand not only by the fleet. "Redoubt" will allow to cover coastal cities, naval bases or especially important areas with an "anti-aircraft umbrella".

The new corvettes are equipped with an automatic control system (ACS), which allows transferring any data from one ship to another in real time. ACS can intelligently distribute targets between several floating craft, ensuring that the same ship, aircraft or cruise missile will not be attacked twice unnecessarily.

Sources in the military department and the military-industrial complex told Izvestia that all corvettes of the new series planned for construction after 2020 will receive integrated Zaslon radar systems. They are capable of effectively detecting devices made using stealth technology at a distance of 75 km, and simpler targets at least 300 km away. Also, according to the interlocutors of the publication, a fundamental decision has now been made to transfer most of the built ships of the project 20380 to strengthen the Navy grouping. in the Pacific Ocean.

The Barrier antenna unit is fixed at the base of the mast and looks like a pyramid with a large number of faces. Hidden behind each face are stationary transceivers that track the movements of various objects. Radar operators can receive on screens an accurate and continuous picture of the air, surface and ground situation in real time. In traditional installations, it is interrupted due to the rotation of the transceiver unit. The complex includes a control room, a command post, posts of high-frequency and radio-technical devices.

An ordinary radar station sees sea targets only to the horizon, Admiral Valentin Selivanov, former chief of the main headquarters of the Navy, told Izvestia. - And a few decades ago, radars were invented, the signal of which bends around the bends of the earth, goes beyond the horizon and returns with information about the target. If we have already reached the point that they have created an over-the-horizon station that can be installed on ships, then this is very good. Corvettes are armed with cruise missiles, and their firing range is much greater than the distance to the horizon. Thanks to the new radar, corvettes will be able to independently detect the enemy, without waiting for any target designation.
