Project 20380 corvettes- multi-purpose patrol ships of the near sea zone, developed for the Russian Navy. At the beginning of 2011, the lead ship of the project, the corvette Steregushchy, was in service with the Russian Navy, and four more ships are under construction. New corvettes should become the backbone of the Russian Navy in the near sea zone.

The lead corvette Steregushchy was laid down on December 21, 2001 at the Severnaya Verf Shipyard. Some time later, three more ships of the same type were laid down at the same shipyard - Soobrazitelny (May 20, 2003), Boykiy (July 27, 2005), and Stoykiy (November 10, 2006). Another corvette, “Perfect,” was laid down on June 30, 2006 at the Amur Shipyard in Komsomolsk-on-Amur. In total, the command of the Russian Navy plans to build a series of 20 multi-purpose corvettes of Project 20380 (3-8 for each fleet).

Project 20380 corvettes are designed:
- for actions in the near sea zone of the state, combating surface ships and enemy submarines;
- for artillery support of amphibious assault forces during amphibious landing operations by launching missile and artillery strikes on ships and vessels at sea and bases;
- to patrol the area of ​​​​responsibility for the purpose of blockade.

The Project 20380 corvette is distinguished by its multifunctionality, compactness, stealth, and high level of automation of ship systems. The modular principle of the architecture of the ships of this project makes it possible to install new weapons and electronic weapons systems on them during the construction of new and modernization of existing corvettes. This reduces production costs and provides high modernization potential for 30 years life cycle ship.

Hull and superstructure

Corvette hull - smooth-deck steel. It is fundamentally new in design and differs from the generally accepted ones, which is one of its main features. New contours of the underwater part of the hull made it possible to reduce water resistance when the ship was moving at a speed of about 30 knots by approximately 25%, and also made it possible to reduce the required power of its main power plant.

Thanks to the new design of the underwater part of the hull, it became possible to use a less powerful and at the same time lighter power plant, which led to the release of 15-18% of the displacement, which can be used to increase the combat load of the ship. While maintaining the mass of weapons and power plants unchanged by reducing the resistance to the movement of the ship, the speed full speed the corvette can be increased by 1.5-2 knots.

The ship's superstructure extends from side to side and is made of multilayer composite materials(flammable multilayer fiberglass and structural materials based on carbon fiber), which was carried out taking into account the requirements of the so-called “stealth” technology.

In the stern of the corvette, for the first time for domestic ships of this displacement, there is a hangar with a take-off and landing platform for the Ka-27 anti-submarine helicopter, and there is also a significant (up to 20 tons) supply of fuel for it.

Starting from the first production ship (“Smart”), “the general customer’s decisions regarding weapons, general ship systems, communications complex, and automation systems were implemented. During the implementation of the project, the design of the ship’s hull and superstructure changed significantly.”

Main power plant

The main power plant (GPU) of the Project 20380 corvette is a two-shaft diesel unit consisting of two DDA (diesel-diesel units) DDA12000, created by specialists from the Kolomna Plant for Navy Russia and successfully passed interdepartmental tests in 2006. Each DDA consists of two 16D49 diesel engines and a reverse gear unit.

DDAs provide high power in reversing modes with minimal fuel and oil consumption; they are equipped with a modern microprocessor control system and monitoring of basic operating parameters. Through summing reversible gearboxes, the motor units operate two fixed-pitch propellers. 4 diesel generators 22-26DG with a power of 630 kW each provide consumers with a voltage of 380 V (50 Hz).

By reducing the noise level of the power plant mechanisms, the visibility of the ship in the hydroacoustic range was reduced - for the first time in the practice of Russian shipbuilding, technologies previously tested on the latest generation of Russian nuclear submarines were used on a surface ship.

With an economic speed of 14 knots (full - 27 knots), the corvette's autonomous cruising range reaches 4,000 nautical miles. The crew of the ship with a helicopter maintenance group is 99 people.

Armament

Anti-ship complex
The armament of the Project 20380 corvette includes complexes of strike, anti-aircraft and anti-submarine weapons, combat control, detection, target designation, communications and protection systems. The basis of the corvette's anti-ship weapons is the anti-ship missile system"Uran" consisting of two four-container launchers with an ammunition load of 8 anti-ship missiles X-35 and a firing range of 130 km. Container launchers are located across the center plane in the middle part of the hull.

Anti-aircraft missile system
The ship's air defense is implemented due to the combat capabilities of the Kortik-M anti-aircraft missile and artillery system (on the tank), portable anti-aircraft missile systems“Igla” (for launching from the shoulder) and two six-barreled 30-mm AK-630M artillery mounts (in the stern). The firing range of ZRAK Kortik-M missiles reaches 10 km. On production corvettes, instead of the Kortik-M air defense system, it is planned to install the Redut air defense system (9M96M, 9M96E or 9M100 missile defense systems) in the VPU.

Artillery
The corvette's artillery armament is represented by the universal 100-mm A-190 gun mount with a maximum rate of fire of 80 rounds per minute, a firing range of 21.3 km, an altitude reach of 15 km and an ammunition capacity of 332 rounds. Naval artillery fire control is carried out using the 5P-10 Puma artillery fire control system. The antenna post of the system is located on the bow superstructure.

Anti-torpedo, anti-submarine and anti-sabotage weapons
The anti-torpedo protection system of the Paket-NK ship consists of two four-pipe 330 mm devices located on the sides in the ports. Torpedoes launched from torpedo tubes can be used both directly against enemy torpedoes heading towards the ship, and against submarines. To detect and destroy submarines, the corvette is equipped with a permanently deployed Ka-27PL helicopter.

For the purpose of close-range self-defense from pirates or underwater saboteurs, Project 20380 corvettes are equipped with two 14.5-mm machine gun mounts and two DP-64 anti-sabotage grenade launchers.

Radio-technical weapons

The ship's radio equipment, in addition to the Sigma BIUS, includes:
— radar station(radar) general detection "Furke-2";
— Target designation radar for guided missiles “Monument-A” in a radio-transparent fairing combined with the foremast structure;
— two navigation radars;
— hydroacoustic complex “Zarya-2” with an antenna in the bow bulb;
— hydroacoustic station “Minotaur-M” with an extended towed antenna;
- OGAS "Anapa-M", automated communication complex "Ruberoid", electronic warfare equipment and navigation.

For self-defense from enemy detection equipment and its anti-ship missiles, the ship is equipped with four ten-barreled PK-10 launchers of the “Smely” jammer complex (two between the helipad and the hangar and two behind the A-190 AU. The purpose of providing radio navigation for the anti-submarine helicopter is mounted on the roof of the helicopter hangar antenna posts of the OSPV-20380 station.

Seaworthiness
The improved seaworthiness of the Steregushchy-class corvettes, compared to the seaworthiness of ships of the same displacement, with equal restrictions on pitching, allows the use of ship weapons in sea conditions of up to 5 points.

Combat survivability

When designing the corvette, special attention was paid to protecting and increasing the survivability of the ship. The project designers implemented “ latest achievements to reduce visibility in the radar and infrared ranges based on architectural features in combination with special coatings, missile weapons and antenna posts built into the hull, the use of materials with high radio-absorbing properties, local protection of individual hull elements, weapons and technical means that have a decisive influence on the formation physical fields of the upper hemisphere of the ship."

The average circular effective dispersion surface (RCS) on the ships of the project was reduced by about 3 times compared to similar ships (the probability of targeting a corvette with anti-ship cruise missiles was reduced from 0.5 to 0.1). On Steregushchy-class corvettes, a set of measures has been implemented to ensure combat and operational survivability (explosion and fire safety and structural protection from the effects of enemy weapons).

At the International Maritime Defense Show (IMMS-2017), which opens today in St. Petersburg, the latest models of warships of the future are presented.

They were developed by Krylovsky specialists scientific center. The corvette whose project is called “Breeze” stands out. Previously, there were no corvettes in our fleet at all. Ships similar to Western ones in displacement and armament were called patrol ships of the near sea zone. They were supposed to protect waters and coastal areas within state maritime borders.

However, the development of naval technologies made it possible to build ships of small displacement, which began to have excellent seaworthiness, have a long cruising range and very powerful weapons. The saying is quite applicable to them: the spool is small, but expensive. At the same time, the main value of corvettes is not in their cost - they are relatively cheap, but in their combat effectiveness.

When developing the concept of the corvette of the future, St. Petersburg shipbuilders focused on optimizing its seaworthiness. Fortunately, the unique experimental base of the Krylov Scientific Center allows us to select the most successful contours and the entire architecture of the ship using models.

The result was a completely new form of the underwater part. This, in turn, gave the corvette increased stability during sea motion, significantly reduced water resistance and made it easier to control the movement. New form hull, which was confirmed by experiments in special pools, reduces wave resistance by half, and the total resistance by a quarter at full speed. The shape of the corvette's bow bulb is interesting. It contains additional anti-roller wings.

When developing the concept of the corvette of the future, St. Petersburg shipbuilders focused on optimizing its seaworthiness

With the same engine power as on similar ships of this rank, a significant increase in speed could be achieved. But the designers proposed a different option. The speed remained the same, but power point became less powerful, more compact and economical.

Thanks to this approach, significant volumes were released inside the case. And this made it possible to saturate the corvette a large number and a wide variety of different weapons. His firepower has increased significantly.

The number of cells of universal vertical launchers for guided missile weapons has increased to 24 units while maintaining the size and displacement of the ship. Typically, the number of such launchers on ships with a displacement of about 2000 tons does not exceed twelve. The main missile armament is anti-ship or universal, that is, missiles can also strike ground targets.

The air defense of a Breeze-class corvette is quite powerful. These are 16 long-range anti-aircraft guided missiles and 32 short-range guided missiles. Anti-aircraft missile defense is complemented by a universal 100 mm automatic artillery mount and two 30 mm rapid-fire machine guns. In this case, the machines can be six-barreled or, in the “Duet” version, twelve-barrel.

To combat submarines and for anti-torpedo protection, two four-tube “Packet” torpedo tubes of 324 mm caliber are provided on the left and right sides.

The normal displacement of the Breeze corvette is 1980 tons, the full speed is 30 knots, the cruising range is 3500-4000 miles. Autonomy is 15 days, which allows you to make raids far from your native shores. Other new products of the Krylov Center - universal landing ship"Priboy", destroyer "Leader" and aircraft carrier "Storm". The designs of these ships have been worked out in detail. They can be built in the interests of the Russian Navy or for export.

As independent experts note, the destroyer “Leader” is not inferior to modern and promising ones in terms of its set of characteristics. foreign analogues. And the project of the landing ship “Priboy” is currently the best in the world in terms of its overall set of characteristics.

The next International Naval Show (IMMS-2017) has finished its work in St. Petersburg. The era of large state defense orders is coming to an end, and the desire of shipbuilders to take their share of work and money is only growing. The fleet, in turn, is searching for new design solutions.

It's getting crowded on Vasilyevsky Island. Before us is the last IMDS, held on the territory of the Lenexpo complex in Gavan. Starting in 2019, the salon will be moved to Kronstadt, to the site of the Patriot Park branch being created there. This will certainly complicate logistics and the work of the participants - after all, for a multi-day business event, Vasilievsky is much more accessible than Kotlin.

Noting the inexorable desire of the current leadership to gather all major military-industrial exhibitions in the territories of their new brainchild (other examples: Russia Arms Expo and the MAKS air show), I would only like to carefully wish that the opposite process does not happen under the next heads of the military department. “New brooms” often have new hobbies, which can have a negative impact on the costs and efficiency of established, traditional events, whose life cycle is designed for several generations of federal dignitaries.

Perhaps the main premiere of the salon was the long-awaited display of the Pantsir-M anti-aircraft missile and artillery system (in the export version "ME"). The long road to the new “horned” weapon, as this type of weapon was disrespectfully nicknamed in the navy, is finally coming to an end. The line of the Soviet "Kortik" finally received a very promising successor, already growing out of the usual framework of the "self-defense complex": the far border of the affected area was pushed back from 8-10 kilometers at "Kortik" ("Kortika-M") to 20 kilometers, and the upper - from 4-6 to 15 kilometers. “Pantsir-M” is multi-channel: the combat module can simultaneously fire at up to four targets with four missiles aimed at them (the “Dagger” modules could fire only one missile at one target).

The air defense missile system is planned to be installed on new ships of the Navy, where such weapons are provided (for example, on the Project 22800 Karakurt small missile missile system), and on modernized ones (instead of the “Daggers” installed there).

Class drift

In the realities of domestic shipbuilding, a new subclass of ships began to emerge. The Northern PKB (design and construction bureau) began developing a “heavy” (displacing more than 2000 tons, how much more is not specified) corvette of Project 23800. Interest in the design and construction of large corvettes in this size (up to 4000 tons) was reported in a conversation with a correspondent and representatives of the Zelenodolsk shipyard.

There has already been a “heavy corvette” in our recent history of shipbuilding - Novik, multi-purpose patrol ship project 12441 “Thunder”, founded in 1997 with great fanfare. The construction was not completed due to financial reasons (the lead ship at 2001 prices cost 8 billion rubles), as well as due to the unavailability of the weapon systems. Some of the design solutions (in particular, the propulsion system and the Redut multi-channel air defense system, which existed only on paper) were dragged onto the new frigate of Project 22350, which was being conceived just then.

Technically, this makes sense. The classes of corvette and frigate, established by the fleet almost 20 years ago, have noticeably swollen, and they are becoming a bit crowded. The frigate of the modernized Project 22350M (in the jargon - “Supergorshkov”), as they wrote six months ago, will become heavier by at least a thousand tons. At the current salon, Deputy Commander-in-Chief of the Navy for Armaments, Vice Admiral Viktor Bursuk, said that the increase in displacement will be even more significant - up to 8,000 tons. The corvette “Daring”, laid down in St. Petersburg under project 20386, has a displacement of 3400 tons versus 2200 for the basic project 20380.

It is not yet clear whether the fleet still needs something in the range of 1500-2000 tons - between the “heavy corvette” and small missile ships. Let us recall that it was from this size class that, from the late 1990s, a multi-purpose ship of the near sea zone grew, which later became the corvette of the long-suffering Project 20380. Initially, they were going to replace the Soviet specialized “babies”, including small missile ships of Project 1234 and small anti-submarine ships of Project 1124. But the time of design and redesign passed, the total displacement exceeded 2200 tons, and the expensive (and still unfinished) Redoubt was dragged on board.

On at the moment it is quite possible to repeat the ship according to the initial design data: “Urans” as strike weapons, “Pantsir-M” in the air defense circuit and “Packet” as an anti-submarine weapon (or a new guided missile used from Uran missile launchers, similar to the American container versions of the previous generation, where the ASROC and Harpoon launchers were unified). The only question is whether the fleet needs such a ship.

And the models are...

The Krylov Center believes that everything is still required. The press was presented with a new corvette "Breeze" with a normal displacement of 1980 tons. True, going back to one of the four very old variants of the so-called “Corvette XXI” - this is a big greeting from the early 2000s, when the design of the ship’s appearance was underway for the future project 20380.

The corvette must give 30 knots and at the same time carry a monstrous composition of on-board weapons: 24 UKSK launchers for “Onyx” and “Caliber” and 16 launchers for a certain “long-range air defense system”. The latter seems to indicate “Redut”, but the fact is that in the original project “XXI-2” (elements of which are completely repeated by “Breeze”) it was the S-300FM “Fort-M” air defense system with the 48N6 family of missiles. With the declared capabilities for missile defense of formations (and, probably, the composition of electronic weapons required for such a case).

We will leave the question of how all this can be placed in 1980 tons to shipbuilding professionals, and the question of cost finished product - .

However, the military had previously been quite skeptical about “ship modeling”, which was demonstrated with enviable consistency within the walls of the St. Petersburg salon. “Models are models,” Vice Admiral Viktor Bursuk, Deputy Commander-in-Chief of the Navy, politely responded to the question of whether the Navy will build the notorious universal landing ship “Priboy”, and this time presented at the stand.

After which he noted that the fleet would order two ships of this class (without specifying the project), with the goal of receiving them by 2025. From the report for 2015 (later ones are not available) it is known that from the type of landing ships two years ago they settled on two options. This is a landing helicopter dock ship with a displacement of 15 thousand tons and a universal landing ship with a displacement of 35 thousand tons. None of these projects, as far as one can judge, has yet leaked to the public.

Consolidation behind the scenes

Meanwhile, in the industry, which has already gorged itself on a lot of money, has considered the limits of this fountain of abundance in the form of the completion of the “State Armament Program - 2020” and has realized its organizational and technological limits, hidden processes of consolidation are growing.

For at least two years now, a plot has been developing around the attempts of the Ak-Bars holding, which controls the Zelenodolsk shipbuilding plant, to acquire the Zelenodolsk Design Bureau of the same name, which is organizationally part of the state.

Moreover, the plans in Zelenodolsk are big: in a conversation with Lenta.ru, the general director of the plant, Renat Mistakhov, noted that in the future, we should be talking, in fact, about the creation of a wide-profile machine-building holding, combining a number of competencies and production facilities that are in demand in shipbuilding. In particular, we are talking about the production of shafts, steering gears, gearboxes and propulsion systems, as well as control systems. If a classic shipyard, Mistakhov emphasized, concentrates the production of 10-15 percent of the cost of the finished ship (and the rest goes to completers), then after consolidation they plan to produce up to 40 percent of the cost of the final product.

USC itself is strongly against this project, but this is understandable: the appearance of a competitor in the industry is unlikely to be welcomed by anyone except the customer. However, government officials clearly favor the project. The Deputy Prime Minister stated that, in his opinion, the Zelenodolsk Bureau “should work in Tatarstan.”

The issue has already twice reached the level of a draft presidential order, but both times it was stopped for revision. The last time this happened was in May of this year after a potential transaction involved the transfer of part of the shares to the government of Tatarstan.

The processes of intra-industry consolidation outside state monopolies in the context of an inevitable fall in state defense orders are absolutely natural: there is a fight over costs and a shrinking food supply. It would be interesting to see what Ak-Bars will end up with and how competition will affect the growth of domestic shipbuilding capabilities. The cost of the full-scale implementation of the project is still very high: according to Renat Mistakhov, the required investments amount to at least 10-15 billion rubles.

TASS DOSSIER. On July 20, 2017, the Russian Navy flag was solemnly raised on the Project 20380 corvette "Sovershenny". Built at the Amur Shipyard (Komsomolsk-on-Amur, Khabarovsk Territory), the ship became part of the Pacific Fleet Russian Navy.

In my section dedicated to, the lion's share of materials is devoted exclusively to Western projects. And this is unfair, because Russia also builds ships that are in no way inferior to their Western counterparts.

This is largely due to the fact that our press has paid very little attention to this aspect. For example, articles on English I came across a huge number of articles dedicated to this ship, but only one in Russian, and then on the specialized naval website “Atrina” (surprisingly, even on the website of the design bureau that designed this ship, there is no article as such, only performance characteristics) , about which most history buffs and military equipment they just don't know.

Actually, I present to your attention this article and the ship itself.

Project history

The new Russian multi-purpose patrol ship of the near sea zone of Project 20380 was designed for Russian Navy at the Federal State Unitary Enterprise Central Marine Design Bureau "Almaz" in St. Petersburg. Its creation was due to certain difficulties associated with the implementation of the previous multi-purpose ship of a similar class, Project 12441, since the lead ship “Novik”, laid down back in 1997 at the shipyards of the Yantar Shipyard, was never completed at the time. In this regard, after a competition, in which the FSUE TsMKB Almaz won, the command of the Russian Navy decided to begin construction of a simpler and cheaper ship, Project 20380, which was classified as a corvette (previously, such a class did not exist in the USSR Navy, and similar ships were classified as TFR). Direct military-scientific support for the creation of this ship was carried out by the 1st Central Research Institute of the Ministry of Defense of the Russian Federation. In total, more than 70 Russian research, design and industrial enterprises(including Aurora, Kolomensky Plant, Sredne-Nevsky Shipyard, etc.).

Multi-purpose patrol ship (corvette) pr. 20380 is designed for operations in the near sea zone of the state and combating enemy surface ships and submarines, as well as for artillery support of amphibious assault forces during amphibious landing operations by launching missile and artillery strikes on ships and vessels at sea and bases, patrolling the area of ​​responsibility for the purpose of blockade.

Design Features

The ship has a smooth-deck steel hull and a side-to-side superstructure made of multilayer composite materials (flammable multilayer fiberglass and carbon fiber-based structural materials), which was made taking into account the requirements of the so-called “stealth” technology. The hull of the corvette pr. 20380 is fundamentally new in design and differs from the generally accepted ones, which has become one of its main features. New contours of the underwater part of the hull made it possible to reduce water resistance when the ship was moving at a speed of about 30 knots by approximately 25% and, at the same time, the required power of its main power plant. As a result, it became possible to use a less powerful and lighter power plant, which led to the release of 15-18% of the displacement, which can be used to increase the combat load. While maintaining the same mass of weapons and power plants, by reducing the resistance to the movement of the ship by 1.5-2 knots, its full speed increases.

The improved seaworthiness of the corvette pr. 20380, in comparison with the seaworthiness of ships of the same displacement, with equal restrictions on pitching, allows the use of its weapons in sea conditions of up to 5 points (1.5–2 points more than similar ships), which is especially important when based on a helicopter ship. In the stern of the corvette, for the first time for domestic ships of this displacement, there is a hangar with a take-off and landing platform for the Ka-27 anti-submarine helicopter, and there is also a significant (up to 20 tons) supply of fuel for it.

Particular attention is paid to protecting and increasing the survivability of the ship. The latest achievements were implemented to reduce visibility in the radar and infrared ranges based on architectural features in combination with special coatings, missile weapons and antenna posts built into the hull, the use of materials with high radio-absorbing properties, local protection of individual elements of the hull, weapons and technical means that provide a decisive influence on the formation of the physical fields of the upper hemisphere of the ship. The average circular effective dispersion surface (RCS) of a corvette is reduced by about 3 times compared to similar ships, which reduces the probability of targeting anti-ship cruise missiles at it from 0.5 to 0.1. In addition, the ships of Project 20380 are provided with a set of measures to ensure combat and operational survivability, including explosion and fire safety, structural protection from the effects of enemy weapons and other measures.

The ship pr. 20380 is equipped with a complex technical system weapons as part of strike, anti-aircraft and anti-submarine weapon systems, combat control, detection, target designation, communications and protection. The basis of its armament is the Uran anti-ship missile system, consisting of two four-container launchers (ammunition 8 Kh-35 anti-ship missiles, firing range 130 km), located across the diametrical plane in the middle part (similar to SKR pr. 11540). For air defense, the ship is equipped with the Kortik-M air defense missile system (in the bow), the Igla MANPADS (for shoulder launch) and two 30-mm AK-630M artillery mounts (in the stern). At the same time, the modernized version of the Dirk combat module has a weight reduced by 2 tons and a missile firing range increased to 10 km. The main artillery armament is represented by the universal 100-mm A-190 artillery mount with 332 rounds of ammunition (maximum rate of fire 80 rounds/min, firing range 21.3 km, height reach 15 km). Fire control of 100 mm and 30 mm artillery is carried out the latest system 5P-10 “Puma”, the antenna post of which is located on the bow superstructure. The unique anti-torpedo protection system “Package-NK” is represented by two four-pipe 330 mm devices located on the sides in the side ports. Its torpedoes can be used both directly against enemy torpedoes heading towards the ship, and against submarines. The permanently deployed Ka-27 helicopter is also designed to detect and destroy submarines.

The ship's radio-electronic armament, in addition to the Sigma BIUS, includes the Furke-2 general detection radar, the Monument-A guided missile target designation radar in a radio-transparent radome combined with the foremast structure, two navigation radars, and the Zarya-2 hydroacoustic complex with an antenna in the bow bulb, the Minotaur-M hydroacoustic station with an extended towed antenna, the Anapa-M OGAS, the Ruberoid automated communications complex, electronic warfare and navigation equipment. To protect itself from enemy detection equipment and its anti-ship missiles, the ship is equipped with four PK-10 launchers of the Smelyi missile jamming system. For self-defense and protection from pirates or underwater saboteurs, Project 20380 has two pedestal 14.5-mm machine gun mounts and two DP-64 grenade launchers. The use of weapons is possible in sea conditions of up to 5 points. To ensure radio navigation of the anti-submarine helicopter, antenna posts of the OSPV-20380 station were mounted on the roof of the hangar.

The modular principle of the architecture of ships of this project makes it possible to install new weapons and electronic weapons systems on them during the construction of new ones and the modernization of existing ones. This reduces production costs and provides high modernization potential over the ship's 30-year life cycle.

The power plant of the corvette pr. 20380 is a two-shaft diesel unit consisting of two pairs of 16D49 type engines operating through summing reversible gearboxes driving two fixed-pitch propellers. 4 diesel generators 22-26DG with a power of 630 kW each provide consumers with a current of 380 V (50 Hz). By reducing the noise level of its power plant mechanisms, the visibility of the ship in the hydroacoustic range was reduced - for the first time in domestic practice, technologies that had previously been tested on our latest generation nuclear submarines were used on the NK.

In general, the corvette pr. 20380 differs from the anti-submarine ships currently in service in its versatility, compactness, stealth, and high level of system automation. With an economical speed of 14 knots (maximum 27 knots), the corvette's autonomous cruising range reaches 4,000 nautical miles. The crew of the ship with a helicopter maintenance group is 99 people.

Modifications

In addition to the serial ship Project 20380 for the domestic fleet, the Federal State Unitary Enterprise TsMKB Almaz simultaneously developed an export version of it, which received the project number 20382 and the code “Tiger”. This ship is distinguished mainly by the presence of simplified weapons in export version and the ability to replace necessary systems to analogues of Western production, depending on customer requirements.

It is expected that starting from the 5th ship of the Steregushchiy type, some changes will be made to the project, in particular regarding anti-ship and anti-aircraft weapons. Most likely, the Kortik-M complex will be replaced by a new medium-range air defense system with vertical launch systems (for example, Poliment), and the Uran anti-aircraft missile system will be replaced by Onyx or Club, also with UVP.

Construction program. On December 21, 2001, the laying of the lead corvette Steregushchy took place at the Severnaya Verf Shipyard OJSC. Some time later, two more of the same type were laid down - on May 20, 2003, "Smart" and on July 27, 2005, "Boikiy", and then two more.

In total, it is planned to build a series of 20 multi-purpose ships of Project 20380 (5 for each of the fleets), and 4 of them should be delivered to the fleet by 2015.

Status for 2008

New corvettes should become the backbone of the Russian Navy in the near sea zone. The first two corvettes will enter service with the Northern and Baltic fleets. They will be used for patrolling coastal waters, escort and anti-submarine operations.

The lead ship of the series, Steregushchiy, was first presented to the general public at a ship held from June 27 to July 1, 2007 in St. Petersburg III International naval show under its export name "Tiger".
