Corvettes of the Visby project (Sweden)

50
The Swedish naval forces, despite their small numbers, can claim the title of the most modern fleet a world with unique "ships of the future." One of the most popular types of ships in the Swedish Navy are Visby corvettes. These ships are of great interest, at least because of their unusual appearance. Behind this appearance lies the desire of shipbuilders to reduce the visibility of ships for enemy surveillance. Thus, the Swedish Navy became one of the first military fleets in the world to receive ships built using the so-called. stealth technology.


Since the late eighties, the Swedish shipbuilding industry has been working on the project of the experimental ship Smyge. During the development of this vessel, some new ideas and technologies were introduced. Later, part of the know-how of this project was used to create new ships, primarily Visby-type corvettes.

Actually the development of promising corvettes started in the first half of the nineties. Initially, the fleet command ordered the creation of two new projects under the symbols YSM (Ytstridsfartyg Mindre - "Small Warship") and YSS (Ytstridsfartyg Större - "Big Warship"). In the future, the country's leadership ordered a reduction in military spending, which resulted in the rejection of two separate projects. Different ideas and ideas for two projects decided to unite in one. As a result, specialists from Kockums, with the assistance of the fleet and the Royal Institute of Technology, developed the YS2000 project (Ytstridsfartyg 2000 - “The 2000 Battle Ship of the Year”).

Combining projects YSM and YSS affected the appearance of the new YS2000. It was assumed that the "Ship 2000 of the Year" will be able to solve a wide range of different tasks that were previously planned to be distributed between ships of two types. Thus, a promising ship had to destroy surface and coastal targets, search for and destroy submarines, conduct a search for sea mines, escort convoys, etc. One of the consequences of this were serious differences in the composition of the equipment and weapons of serial ships.

The decision to build a new corvettes project YS2000 was taken in 1995 year. In mid-October, Kockums received an order for the first two ships of the series. In accordance with the first contract, the shipyard was to build and transfer to the fleet two ships, HSwMS Visby (K31) and HSwMS Helsingborg (K32). In December, the 96 fleet ordered two more ships named HSwMS Härnösand (K33) and HSwMS Nyköping (K34). The third contract of August 1999 of the year implied the construction of two ships, but was soon shortened. The ship building program was too expensive, which was why the military department was forced to abandon the sixth corvette. The fifth ship, in turn, received the name HSwMS Karlstad (K35).

It should be noted that the command of the Swedish Navy did not immediately decide to reduce the series. In October, 2001 was made only a preliminary decision. The military reserved the right to re-order the corvette until the autumn of 2003, but did not use it. According to reports, the construction of the five ships cost the Swedish treasury 0,9 billion US dollars.

The lead ship of the series, the Visby, was laid at the Kockums factory in Karlsruhn in February 1995. The construction of the corvette was delayed for several years. Due to the use of the mass of new technologies and some problems of a different nature, the ship was launched only in the middle of the 2000 year. Further completion was also accompanied by serious difficulties. There were problems with the supply of various equipment and weapons. As a result, part of the test ship passed with incomplete equipment. For example, in 2008, it was reported that the HSwMS Visby corvette had not yet received all the weapons and was equipped with only a cannon.

The second and third ships of the project were laid in the summer and winter of 1997. In the middle of 98, the construction of the Nyköping ship began, and the Karlstad was laid at the very end of 1999. The construction of the sixth ship did not begin, but part of the equipment for it was ordered. Subsequently, this equipment was used in the construction of the shore simulator for the crew.

A characteristic feature of the Visby project became the so-called. version. Since the ships did not immediately receive all the necessary equipment and weapons, classification was applied with versions differing from each other in numbers. So, in the middle of December 2009, the contracting company handed over to the fleet the first two completed ships, HSwMS Helsingborg and HSwMS Härnösand. At this point, the ships received all the necessary equipment and weapons, although only an artillery unit was tested. The term “4 version” was used to denote this configuration.

In 2012, it became known about the development of the so-called. 5 versions. This version of the project is characterized by an updated composition of the equipment and some design changes. During the upgrade to this version of the ship's hull receives some new parts, also installed new equipment to search for mines and anti-ship missiles. In addition, the 5 version of the project allows the ship to carry a helicopter. The first to upgrade version 5 went Corvette "Visby".

One of the main goals of the Visby project was to reduce the visibility of ships for enemy surveillance equipment. The most noticeable consequence of this is the characteristic appearance of the corvettes. All the necessary components and assemblies are located inside the case, consisting of a set of flat panels. Also, to reduce visibility reduced superstructure, which is a block consisting of two main parts. In front of the superstructure, having the shape of a truncated pyramid, there is a bridge, in the back - an open area with missile launchers.

The main material of the ship hull is a composite material based on polyvinyl chloride with carbon fiber reinforcement. Such material has high strength and rigidity with low weight, and also almost does not reflect electromagnetic radiation. From composites is performed as the hull of the ship, and its superstructure and other elements. In some sources it is mentioned that the used hull can significantly reduce the range of possible detection of the ship. So, with a calm sea, radar stations notice it from a distance of no more than 20-22 km. With the use of electronic warfare systems, the enemy's detection range is reduced to 10-11 km. At the same time, the range of detection systems of the corvette itself remains unchanged.

The ships "Visby" have a length of 72,7 m, a maximum width of 10,4 m and a draft at the level of 2,4 m. Displacement is only 640 t. Such lightness of construction is provided, first of all, with the materials used. When using metal hull and superstructure, the displacement of the ship could have been significantly greater.

In the stern of the hull, under the helipad, are units of the power plant class CODOG. To improve the performance of the power plant used diesel and gas turbine engines operating alternately. For operation with less power and less fuel consumption, the power plant uses two MTU Friedrichshafen 16V2000 N90 diesel engines with an 1,3 MW power. If necessary, the crew can start four Honeywell TF50A gas turbine engines with an 4 MW power. Three electric generators for each 270 kW are connected to the engines. The engines with the help of gearboxes are connected to two shafts and ensure the operation of two jet propulsion devices developed by Kamewa. This type of propulsion was proposed to be used to improve the driving characteristics of ships.

Due to the sufficiently large power supply, the Visby type corvettes are capable of speeds of at least 35 nodes (when using gas turbine engines). At an economic speed of 15 knots, the cruising range is at the level of 2500 nautical miles.

Visby ships are equipped with the Certis C3 combat information and control system, most of the tasks being performed by two main subsystems: the MAST information support system and the Saab Systems 9LV Mk 3E fire control system. Communication and control systems are designed in such a way that the corvettes can operate autonomously, without constantly maintaining communication with other ships. If necessary, data can be received, but the ship's own emitters may not be used. To suppress enemy’s electronic equipment, ships should use Rheinmetall TKWA / MASS electronic warfare systems.

To meet the challenges of anti-submarine defense, Visby corvettes can carry a range of sonar tools. The project provides for the use of a hydro-acoustic station inside the hull and a towed system of a similar purpose.


The structure of the ship. Figure Alternathistory.org.ua


Before the superstructure, an artillery installation is placed on the deck in a casing of a characteristic complex shape. Inside the casing is a Bofors 57 Mk 3 caliber 57 mm. On the gun installation, the sensors of the SaabTech CEROS 200 fire control system are mounted: a radar station and an optical-electronic system. The gun can fire at a rate of up to 220 shots per minute. Ammunition includes various projectiles, including fragmentation ammunition with a programmable fuse. Such projectiles make it possible to “cover” the target with the maximum possible number of fragments.

A curious feature of the artillery installation is the method of transporting the gun in the stowed position. To reduce the visibility of the entire ship, the gun barrel is lowered into the longitudinal window of the casing and closed with movable flaps. Due to this, no units do not protrude beyond the casing and do not increase the visibility of the ship for radar systems.

Under the platform behind the bridge it was proposed to place launchers of anti-aircraft missiles. For protection from an air attack, it was planned to use the Denel Umkonto air defense system, but later they turned out to be from this. Even after several upgrades, the Visby Corvettes do not have anti-aircraft missiles. Some materials on these ships mention the possibility of installing a small-caliber anti-aircraft artillery mount on a movable base in the stern. In the firing position, it should be extended above the deck and lowered back to the marching position. Similar systems are also not used on serial ships.

Behind the superstructure are the launchers of anti-ship missiles Saab Bofors RBS-15 Mk 2. Ammunition Corvette includes eight such missiles. With this weapons the ship can destroy surface targets at ranges up to 250 km.

To destroy the submarines are encouraged to use jet bombs and torpedoes. Alecto X-Bomb caliber 127 mm are located in the bow of the ship, near the artillery installation. Four torpedo tubes for the torpedoes TP 43 or TP 45 are located in the rear part of the hull, in special lansporta.

The Corvettes of the Visby project, at the request of the military, must search and destroy not only submarines, but also sea mines. To combat these weapons, it was proposed to equip ships with a number of special equipment. The main system of the anti-mine complex is remotely controlled underwater vehicles Bofors Double Eagle. The structure of this system consists of two underwater vehicles, one of which is equipped with a set of sensors, and the second with means of neutralizing mines. Due to this, the operator of the complex can find dangerous objects, and then neutralize them, cutting minrepry or undermining on the spot.

The stern of the ships is a landing pad for helicopters. Aviation the corvette group consists of one Augusta A109 helicopter or other similar machine. The helicopter can carry sonar equipment, missile and bomb weapons, as well as be used in search and rescue operations. Some ships of the project are equipped with a helicopter hangar under the deck.

Five Visby project corvettes have some differences from each other. For some reason, the ships received a different composition of equipment and weapons. Thus, the first four corvettes were initially considered as anti-submarine ships with the ability to search for and destroy mines. Only the fifth and sixth ships of the series should attack enemy ships. In the future, it was decided to change the composition of the armament of the ships, ensuring the solution of various tasks, which is why a new weapon appeared on some corvettes.

For example, at the moment the lead ship HSwMS Visby is equipped with an artillery installation, torpedo tubes, anti-ship missiles and a jet bomb. In this configuration, it refers to the "5 version". The ship HSwMS Helsingborg has a similar weapon system, but it is not equipped with torpedo tubes. The same weapons are used on the third ship of the series, HSwMS Härnösand. In the end, it was decided to upgrade all the ships in accordance with the project "version of 5", but basically it affected only electronic equipment.

The five Visby corvettes were transferred to the 3 and 4 in the naval fleets of the Swedish Navy. Currently, the lead ship serves in the 4 fleet, the rest belong to the 3. To test new ships in the fleet, special connections were created under the name PTK Visby. Formally, they belonged to the flotilla, but submitted directly to the command of the Navy. The task of these units was to test and test the operation of new ships before starting full service.

To date, all five Visby corvettes have been transferred to the fleet and have begun a full service. The first two ships began to serve in December 2009. The remaining corvettes became full-fledged combat units of the Navy only in September 2015. Over the past few years, all ships have been upgraded to the "5 version" and, based on the results of this update, have been officially accepted into the naval forces.

For several years of service, Corbytes of the Visby type several times took part in various exercises, during which they solved antisubmarine defense tasks, searched for mines and carried out other missions. For obvious reasons, such ships have never participated in real hostilities. Because of this, their effectiveness can be assessed only on the basis of the results of training events, but not exploitation in conditions of real conflict.

Previously, there was information about the desire of the Kockums company to offer Visby corvettes to foreign customers. To this end, several new versions of the project were developed, differing from the basic version in size, equipment composition and other characteristics. Published data on the possibility of building the four versions of the ship Visby Family.

The closest version to the original was the Visby Export version, which differed from the Swedish ships with a slightly smaller size and equipment, selected in accordance with the wishes of the customer. The main characteristics of the ship remained at the level of indicators of basic corvettes.

Also offered option Visby Light ("Light"). Such a ship should have a length of about 55-56 m and a displacement of no more than 550 t. Other characteristics, as well as the composition of weapons and equipment, should have been reduced accordingly.

The Visby + project implied the construction of ships with a length of about 90 m and a displacement above 1500 t. The Visby ++ project was also worked out. Such a ship could have a length of more than 100 m and a displacement of the order of 2200 t. According to published materials, it was possible to maintain the driving characteristics of the base ship.

As far as is known, not a single foreign customer showed interest in the export versions of the Visby project. Despite some interesting features, such projects did not find the customer and remained on paper. The only operator of Visby ships remains the naval forces of Sweden. It is hardly to be expected that the list of owners of such corvettes will be added in the near future.

Despite the small number of built ships, the Visby project is of great interest. Swedish shipbuilders were able to solve a number of important problems concerning the expansion of the range of tasks performed, ensuring minimal visibility for enemy detection equipment, etc. The result was the appearance of ships with non-standard appearance and promising characteristics.

The construction, testing and modernization of five ships of the Visby project has been dragged out for almost two decades. From the laying of the first ship to the commissioning of the last three a little over 20 years passed. During this time, the Swedish experts were able to solve the tasks and correct the identified shortcomings. As a result, the Swedish Navy became the first operator of large warships built using stealth technology. Due to this, despite its small size, the Swedish fleet can claim to be one of the most modern in the world.

        Rather, it’s not a small country but a small sea area in which these ships have to go. In addition, the engineers obviously set a clear, concrete task, and received a clear answer. And do not forget they are piece goods :) therefore they can afford to be very meticulous and corrosive.

      It should be noted here that armaments are created not by a country, but by a certain company - for example, in Russia, Almaz-Antey or Irkut, etc.

      But the most important thing. that Swedish companies are "integrated" into the international market. They don't have any sanction. they are considered allies and get everything - from chips and all kinds of electronics to the most modern technology

      Generally. everything that is produced in the West can be considered to what extent collective creativity

      But for example, when Iran or the DPRK do something the same missiles wow! It is surprising - this has already been done in conditions of complete isolation and blockade of the West. True, they had something to start from - old Soviet technologies - and there is also a strong suspicion that China and Russia are still helping the "outcasts" - with drawings, know-how, specialists. And the wound seems to still receive Russian aid

        You are absolutely right! When they talk about how "There" everything is good and thoughtfully, everyone forgets this nuance, namely 1.5 billion literate and intelligent population, all scientific and technical resources are in a water boiler .. and we are like bast shoes, .. But in fact, we have to solve everything the same goals and objectives as these 1.5 billion, having only 140 million .. At the same time, living on 1 \ 7 of the land in very unfavorable natural conditions and at the same time constantly fighting off these 1.5 billion ... that's why the potential in comparison with the bourgeois on ALL and not enough, tanks and missiles for fighters (all vital) are less successful, but for civilian everyday life to be ahead of the entire planet (or at least at the level) is gone! The fact that we have not yet been eaten (and we are food for them and nothing more) suggests that having 10 DIFFERENT advantage the bourgeois world still cannot gnaw us, although attempts have been going on for several centuries. And this fact should surprise most of all!

    Normal relatively budgetary toys of a single country. The size and weapons for operations in the Baltic should be enough. If only the brains were enough to use for their intended purpose. A normal person will think what kind of ships these are, then why, according to the media, the waters of Sweden are a passageway for enemy submarines laughing

        The Swedes do not need air defense on small ships. The only enemy is Russia. We will not be allowed to use aviation in the Baltic, it is all covered by the ground air defense of "our western partners", plus NATO aircraft from all sides.

            No, it’s just that the ship is intended for the Baltic Sea, a shallow sea, the coastline is cut with skerries and fjords, hence the choice of anti-ship missiles (RBS-15 Mk. 2 has a range of up to 250 km on surface targets) and stealth technologies (detection of up to 20-22 km on calm water, with an excitement of 3-4 points-13 km, when setting interference 11 and 8 km, respectively).
            Perhaps the lack of air defense systems is caused by the desire to reduce the cost of the project and is compensated by the Air Force (164 combat aircraft).

              I wonder how the aircraft have time to bring down anti-ship missiles launched from a submarine? Fighters must cut circles over the corvette 24 hours a day, 7 days a week to protect it, and there should be not one plane, but at least half a squadron.

                Judging by ZVO 2/2001 on the KVV, they simply could reserve a place for the air defense systems, like the Norwegians. It smells of confrontation in the spirit of the Cold War-there will be money-put air defense systems, but for now all hopes for stealth.

    Corvettes of the Visby project (Sweden)

    A couple of years ago in VO there was already a publication
    The world's first stealth warships: Visby Corvettes (Sweden)

      Judging by the rating, Kamrad, you’ve been here for a long time :) Surely often encountered self-repetition on this resource, I also wrote about this several times with links to articles. And there was a repeat with an interval of a couple of months. Alas.

          Ryabov simply writes so many articles that one can forget that he published there a week ago lol In general, articles on VO (especially news) began to be repeated. It seems that 2 almost identical articles appear with a break in a couple of days (the last example is with the "Hopak" firearms wassat )

      For a couple of years, repeating on an interesting topic does not seem to me a crime. However, you don’t have time to keep track of all the articles, and it is impossible to re-read the entire VO archive (although I honestly would like to. But the truth is that you only read information that interests you specifically.) A Here are the repetitions of those simply to the wickedness of the day - yes, it annoys. hi

    Good afternoon, Andrey. With hysteria in the media, everything is clear - in the two thousandth countries of Europe, in the wake of the crisis and almost bankruptcy of some states, military spending was greatly reduced. In the wake of the rearmament of the Russian Federation, the EU military (we are not touching it yet) realized that the lag was starting to be accepted as an armament threatening proportions, they wanted to jump into the last car. So that all the submarines of the Swedish media are a well-organized action to increase the military budget (you hope that you don’t think that all politicians in the west see a threat in Russia, most are worried about internal problems) .On account of air defense ships, they probably coastal zone and hope to cover VVS.Vot only one question, they RCC gun to shoot down collected MANPADS or rely on stealth?

    Beautiful corvette. The case where the utilitarianism and laconicism of forms dictated by TK cause aesthetic satisfaction. I remember we had a competition among young engineers and designers for the concept of ships of the near sea zone - there were also impressive works, it is a pity that only in the form of 3D models. Here is a link to some: http://www.photoarmy.org/2011/03/corvette-project-near-maritime-zone.html

    High-speed, inconspicuous RTOs. Yes, even with a helipad and quite stuffed in terms of weapons. I think the issue with the deployment of air defense systems is being solved. A very good boat for the near sea zone.

    A small fleet, which means it is easier to carry out its general modernization, lower requirements for displacement. In general, the Swedes also built quite funny dishes in WWII, but as a result, their comparatively low combat value was revealed.
    For example the hydro cruiser "Gotland", with a similar concept of a large fleet on board. Well, this stealth corvette actually has weak strike weapons, capable of fighting classmates, unlike our universal Buyans, which are not so futuristic in appearance.

      Judging by the fact that the RBS-15 Mk.3 on only one corvette out of five, the shock functions for these ships are not the main thing, at least for the Swedes in modern conditions, like air defense.

    Well, an interesting corvette, except perhaps for show-off. I think our submarine was still there, then and now there is "Varshavyanka" one went to the Black Sea, the other came for further tests before shipping, and so our always fans to play on the nerves of the foe))) Judging by how they have their painted pans banging against the wall in search, that's nothing.

    The architecture is, of course, interesting, but I read and understood the "imperfection", there is no air defense, cannon 57, mine armament only uninhabited vehicles, what anti-sabotage means, what are the opportunities for working in a squadron?

      Which squadron? Swedish Navy-5 PL, 9 KRV, 12 SK, 20 MTShch, 120-187 DK, 1 RTR ship, 15 auxiliary ships. The RSA's artillery / anti-aircraft weapons are even weaker, but this does not mean that all missile boats are "incomplete".

    If at that time it was unequivocally about the Rashkinsky breaking rusty troughs, now now even the small-sitting Buyans suddenly began to nightmarish quite large ships.

    Yes, for one appearance praise the ship ... just criticizing the propulsion system from the last century, because the current trend is full electric movement, i.e. turbine - generator - electric motor. And then the classic scheme from the 70s. So what is he from the future?

      Full electric propulsion is advisable only for large ships, since the specific gravity of such an installation is greater than that of a purely gas turbine unit. The whole point is the use of excess electricity to power weapons systems (radars, railguns), always the optimal mode of operation of the turbines, the lack of need for separate electric generators. What is coming out? USS Zumwalt
      On a ship of 700 tons, all this can’t get ...
