Project 20385 Gremyaschy class corvette - Program

With the propulsion system for ships of project 20385, a whole story arose, which for a long time was one of the main topics in the news media. Initially, the project was created under the import engines, but the deterioration of military-political relations with Western countries led to the disruption of the supply of necessary equipment of the German company MTU. It was urgently necessary to find a suitable replacement.

The Russian Navy needed around 50 Project 20380 vessels to ensure the protection of its coastal waters, as well as its oil and gas transportation routes, especially in the Black and the Baltic seas. However, a shipbuilding industry source told Kommersant that the Project 20180 ship "does not meet modern requirements" and a new class is therefore required.

The Russian Defense Ministry was to hold a competition in September 2010 to select a new corvette for the Navy to replace the Project 20380 class, the business daily said on 23 August 2010, citing sources in the shipbuilding industry. The competition should produce a mobile, fast-moving ship with a helicopter hangar and a distinct modular layout for weapons, Kommersant said. The Project 20380 corvette is deployed to destroy enemy surface ships, submarines and aircraft, and to provide naval gunfire support for beach landings. It uses stealth technology to reduce the ship's secondary radar signature, as well as its acoustic, infrared, magnetic and visual signatures.

Five design centers were likely to take part in the competition, the paper said. Three belong to Russia's United Shipbuilding Coorperation: Zelenodolsk, Severnaya Verf and Almaz. A fourth unnamed foreign shipyard, which specializes in small civilian vessels, is a likely participant, the paper said. If the competition in September is successful, the approved project "will determine the shape of surface shipbuilding for the next 15 years", the source told Kommersant.

St. Petersburg's Severnaya Verf shipyard on 26 May 2011 started construction of a new corvette for the Russian Navy. The project 20385 corvette is a larger and improved version of the Steregushchy class corvette. It uses stealth technology to reduce the ship's secondary radar field, as well as its acoustic, infrared, magnetic and visual signatures. "It is a fundamentally new ship for the Russian Navy; its performance and combat power surpass other ships of the same class," Severnaya Verf said in a statement.

On 03 February 2012 a Project 20385 Gremyashchy corvette was laid down in St. Petersburg, and was expected to join the Russian Navy in 2015. The Gremyashchy is formally the first Project 20385 ship, but it is a further development of Projects 20380 and 20381 corvettes, two of which had already joined the Baltic Fleet, with one more undergoing trials and another under construction. As of February 2012 contracts provided for the building of eight Project 20385 corvettes (the Gremyashchy will be the first).

Russia's Northern Shipyard (Severnaya Verf) had a contract with the Defense Ministry to build a total of 13 warships for the Russian Navy, the shipyards general director, Andrei Fomichev, said on 21 February 2012. These include six corvettes, six frigates and one reconnaissance ship, he said. On February 1, the St. Petersburg based shipyard started construction of two warships - the Project 20385 Gremyashchy corvette and the Project 22350 Admiral Golovko frigate. The Steregushchy and the Soobrazitelny corvettes had already been completed and transferred to the Navy.

Initially it was assumed that an order would be received for the construction of two dozen ships of this type. The domestic defense industry established the production of ship parts from polymeric and composite materials that are to be used in the future not only in the construction of ships of an improved project. Following the lead ship in July 2013, the first production ship, the Corvette Agile, was laid.

Severnaya Verf will build at least 10 Gremyashchy class corvettes for the Russian Navy under a contract with the Defense Ministry. Russias Severnaya Verf laid down a new Gremyashchy class corvette 25 July 2013 at its St. Petersburg shipyard. The corvette Provorny is the second warship of the Project 20385 class. Laying Project 20385 corvette, serial number 1006, was held at the "Severnaya Verf" on the eve of the Day of the Navy July 28, 2013. This is the Central Navy Portal said a source in the enterprise.

Cutting metal for the manufacture of the first section of the body of the sixth Corvette started at the plant in early April. To begin work on welding sections 1006 Order scheduled for the end of April. Manual assembly and welding shop "Severnaya Verf" believes that making mortgages sections of the sixth - the first production Corvette to be fulfilled in time. The ceremony of installation mortgage board the lead ship of the project 20385 (serial number 1005) was held in February 2012, work on the hull of the ship began at the plant in the summer of 2011. The first order of the draft order of the commander of the Russian Navy ships assigned to the legacy of the Russian and Soviet navies name - "Rumbling".

Russian Navy will receive 16 Project 20385 corvettes, the Central Navy Portal reported 25 July 2013. The groundbreaking ceremony corvette "Prompt" on July 25 in St. Petersburg at the shipyard "Severnaya Verf", said Deputy Defense Minister Yuri Borisov. "We have no doubt that the Northern Shipyard successfully cope with the order of the Ministry of Defence - said Yuri Borisov - as well as perform work within the necessary timeframe." Corvette "Agile" has been assigned serial number 1006 - the second housing project 20385 and the sixth in a series of corvettes being built now for the Russian Navy.

Project 20385 corvettes "Gremyashchy" and "Agile" will be delivered to the Russian Navy in time with German diesel engines. This was announced 16 March 2015 by CEO CMDB "Almaz" Alexander Shlyakhtenko. "It was decided to install a diesel engine to the corvette domestic production produced by JSC "Kolomna factory". Delivery times for the Russian Navy ships are not corrected, they remain in accordance with a plan approved by the USC (United Shipbuilding Corporation) and the Russian Navy," - said Shlyakhtenko.

Interlocutor of the agency said that work on the project 20385 did not stop, and now designers and engineers are engaged in the modernization of a Russian engines instead of originally planned installations from the German company MTU. Some media reported that the shipyard in northwest Russia froze the construction of eight corvettes and nine frigates due to the inability to replace imported components.

The project to build advanced Gremyashchy class stealth corvettes will be closed due to insufficient supply of foreign-made components, the shipbuilder said 20 May 2015. Foreign-made equipment was installed on Project 20385 corvettes, and certain problems have emerged due to present-day events, said Leonid Kuzmin, the marketing director of the Severnaya Verf shipyard.

The first two vessels of the Project 20385 class, which is a derivative of the Steregushchy class (Project 20380) corvette featuring better electronics, air defenses and extended operational range, are the Gremyashchy and the Provorny corvettes. The two vessels were in various stages of completion and will be equipped with domestically-produced substitutes of foreign-made spare parts.

Our shipyard is currently building two ships, and the possibility of replacing the [foreign-made] equipment [with domestically produced parts] is now being studied, but, apparently, the two corvettes will remain the only ships of their class. Under the contract with the Defense Ministry, the Severnaya Verf was to build at least 10 Gremyashchy class corvettes for the Russian Navy. The remaining eight ships will be built as the Steregushchy class corvettes.

According to earlier reports, the German contractor MTU terminated a deal to supply engines for the warships last year, citing the sanctions imposed on Russia over the crisis in Ukraine. The engines are to be replaced with their advanced Russian-made counterparts which are still undergoing trials.

Kolomna factory developed a diesel engine capacity of 7500 kilowatts, which will replace imported counterparts on warships of the Russian Navy, in particular - on the upgraded Project 20385 corvettes. Previously it was assumed that the project 20385 corvettes will be equipped with engines of the German company MTU, but after the introduction of sanctions against Russia, this company refused to cooperate.

"By the order of Design Bureau" Almaz "we order import has completed a technical project for one of the new versions of the corvette class ship - Project 20385" - chief designer of the Kolomna Plant Valery Ryzhov said 18 June 2015. He added that the new engine was currently undergoing bench testing, and delivers power up to 7500 kW. According Ryzhov, diesel engines of such power were not produced in Russia.

A series of corvettes of the project 20385 is planned from four ships, the head of the shipbuilding department of the Russian Navy Vladimir Tryapichnikov told reporters 30 June 2017. "The series will be a brigade composition - about four ships. But we should not stand still ... The series will be of four ships, and then we move to building an even more modern and modern corvette with a more powerful and modern complex of the project 20386," he said after the launching ceremony of the corvette "Gremyaschy" project 20385 at the shipyard "Severnaya Verf". He noted that it is advisable to continue this series of ships at the Severnaya Verf, however, the question of placing orders at shipbuilding enterprises of the Far Eastern region is being considered.

As of April 2019, the active phase of construction was carried out only on the lead ship. The Corvette "Agile" will be returned to the cradle of the project 20380, in order to be equipped with domestic components and assemblies. Since June 16, the ship was transferred to the open stock, to carry out further work on the installation and commissioning of the main systems, components and assemblies of the ship. The completion of the installation work is scheduled for the end of 2019, after which the newest combat ship will join the ranks of the Northern Fleet.

To date, the building is limited to two vessels of this class. Talk about laying two more ships of the same type, in addition to those already under construction, ends in the corridors of the Main Naval Headquarters and the Ministry of Defense of the Russian Federation. Most likely, further construction of vessels of this class will be conducted already on the basis of the basic project, which is completely tied to domestic equipment, parts and mechanisms. Both vessels will be completed by the domestic enterprises, which will have to supply all the necessary components, assemblies and equipment instead of foreign analogues. A high-quality and equivalent replacement cannot be achieved; however, according to military experts, such technological innovations during construction cannot significantly reduce the design tactical and technical characteristics of ships.

Information periodically appears in the media that all ships under construction in the framework of the project 20385 will be used to equip the Pacific Fleet. Time will tell how the completion of the lead ship will go and how the fate of the second ship being built as part of this project will be made.

At the end of August 2020, the Ministry of Defense signed a contract for the construction of about a dozen ships of Project 20380. Although the parameters of the document were not officially announced, Izvestia learned some details. All new corvettes will receive unique ultra-long-range radars: Zaslon radar systems, which will make it possible to detect even subtle air and sea objects at a distance of hundreds of kilometers. According to experts, thanks to such radar systems, ships will be able to independently find and destroy the enemy, without waiting for target designation from the air.

The project 20380 multipurpose corvette had become the most massive large warship developed in the post-Soviet era. A total of 15 units will be added to the fleet. By mid-2020 the Russian Navy had six of them. "Guarding", "Smart", "Boyky" and "Steady" serve in the Baltic Fleet, "Perfect" and "Loud" - in the Pacific. "Zealous" and "Strogiy" are being completed in St. Petersburg: according to the plan, they should become part of the Baltic or Black Sea Fleets, respectively. Two more corvettes - "Hero of the Russian Federation Aldar Tsydenzhapov" and "Razkiy" - woul be received by the Pacific Fleet over the next two years.

According to Izvestia's sources in the military department, in 2019 it was decided to suspend the construction of ships of this project. However, it was then revised. On 12 August 2020, during a visit to the Amur Shipyard (ASZ), Defense Minister Sergei Shoigu said that he had arrived at the enterprise, among other things, to understand whether it was capable of launching six more corvettes in eight years. As a result, a contract was signed at the Army-2020 forum at the end of August 2020 to continue construction, Izvestia sources said. The content of the document and the number of ships ordered by the military department were not disclosed. Some of the corvettes that will be laid at the NEA will strengthen the Pacific Fleet, military historian Dmitry Boltenkov believes.

In Soviet times, a powerful ship group was based on Kamchatka; in 1990, almost all large ships were decommissioned there. It is necessary to strengthen this direction. Now two ships are serving in the Pacific Ocean, two more will be sent there in the next two years. But this is clearly not enough. Modern corvettes must perform a number of tasks there: cover Primorye, defend the Kuril Islands, as well as Kamchatka, where strategic missile carriers are based.
