The Blekinge-class submarine is the next generation of submarines developed by Kockums for the Swedish Navy, [4] also known as the A26 type.

Contents

First planned at the beginning of the 1990s, the project was called "U-båt 2000" and was intended to be ready by the late 1990s or early 2000. With the end of the Cold War the naval threat from the Soviet Union disappeared and the new submarine class was deemed unnecessary. [5] The project lay dormant for years until the mid-2000s when the need for a replacement for the Södermanland class became apparent. Originally the Scandinavian countries had intended to collaborate on the Viking class, but Denmark's withdrawal from submarine operations[ citation needed ] meant that Kockums proceeded on their own.

In February 2014 the project was cancelled because of disagreements between Kockums's new German owners, ThyssenKrupp, and the Swedish government. ThyssenKrupp refused to send a complete offer to any potential buyer and demanded that each buyer pay for the entire development rather than sharing the cost. [6] The cancellation resulted in the Kockums equipment repossession incident on 8 April 2014. As per protocol, the Swedish government repossessed all equipment belonging to Defence Materiel Administration (Sweden), as well as all secret blueprints and images, using an armed escort. By orders from a manager, Kockums staff tried to sabotage the repossession by locking the gates with the repossession crew and escort still inside. [6] [7]

Maritime Today on 18 March 2015 reported that the project was restarted after the Swedish government placed a formal order for two A26 submarines for a maximum total cost of SEK 8.2 bn (approximately US$945 million as of 18 March 2015). According to the article, a Letter of Intent (LOI) had earlier been signed by Saab and FMV (The Swedish Defence Material Administration) in June 2014 regarding the Swedish Armed Forces’ underwater capability for the period 2015–2024. Saab has since acquired Kockums. [8] The order in question for the two A26 submarines has been placed with what is now "Saab Kockums." [9] [10] These were to be delivered no later than 2022, a date subsequently pushed back, initially to 2024–25 [11] and subsequently even further to 2027–28. [12]

Features

The new submarine project was intended to be an improved version of the Gotland class, which will be considered obsolete around 2015–2017 according to Per Skantz, development co-ordinator at the Marine headquarters in Stockholm. [13] The submarine would displace 1,900 tonnes [3] and have a crew complement of between 17 and 31 men. [14] The 2008–2010 military budget memorandum to the Minister for Defence by the Supreme Commander Håkan Syrén would require the type to cost no more than the current Gotland class (about 1.5 billion SEK). [13] The new submarine would have blue water capability, something earlier Swedish submarines have lacked. It will be equipped with modified AIP stirling propulsion and GHOST (Genuine HOlistic STealth) technology, making the submarine extremely quiet. It will also be designed to withstand significant shock loads from underwater explosions and would be able to "Launch and recover vehicles" through its torpedo tubes. [15] The submarine's sail would largely be composed of the same material that was used when constructing the Visby-class corvettes. [16]

There are three variants available: the Pelagic, Oceanic, and Oceanic (Extended Range). [17] The entire Blekinge-class submarine family has been offered for export equipped with 18 vertical launch cells for Tomahawk cruise missiles. [18]

Orders

On 25 February 2010 Kockums AB signed a contract with the Swedish Defence Materiel Administration (FMV) concerning the overall design phase of the next-generation submarine. Kockums CEO, Ola Alfredsson, stated "This is an important first step, not only for Kockums, but for the Swedish Armed Forces as a whole. We shall now be able to maintain our position at the cutting edge of submarine technology, which is vital in the light of current threat scenarios." [19] [20]

The Royal Norwegian Navy had shown interest in the project and could be interested in buying several submarines in the future. According to Kockums AB orders must be made by the end of 2010. [21] [22]

On 11 April 2010, the Swedish Defence minister Sten Tolgfors announced plans to acquire two new submarines to be commissioned in 2018–19 replacing the two submarines of the Södermanland class. The plans also included a Mid-Life Upgrade program of two submarines of the Gotland class. Additional submarines could later be ordered to replace the Gotland class, however this will not be decided before 2020. [1] [2]

On 16 June 2010, the Swedish Parliament authorised the government to procure two new submarines. [23] [24] Kockums states that construction of two A26 submarines will generate about 170 jobs. [25]

The first submarine was planned to be laid down by the end of 2012, but as of 2013, no submarines have yet been ordered. [26] In September 2013 it was announced that the project had been delayed because of construction issues and the first submarine would not be ready before 2020. [27]

Order cancelled and alternatives

On 27 February 2014, the Swedish Defence Materiel Administration (FMV) cancelled its plans to order the A26 submarine from Kockums. According to FMV the new Kockums owner, the German company Thyssen Krupp has refused to allow Sweden to share the cost with any other nation, making the submarine too expensive. Sweden has instead approached Saab. [28] [29] Saab plans to rehire many of Kockums submarine engineers if they receive orders for a new submarine. [30] [31] As a result, Saab recruited top people from Kockums and issued a press release that the company was seeking employees for its naval division. In a letter to the Swedish Defence Materiel Administration, FMV, the head of the German ThyssenKrupp Marine Division, Dr. Hans Atzpodien begs FMV to stop Saab from recruiting key personnel from Kockums. On 2 April 2014 the Swedish government officially terminated all talks about a deal with ThyssenKrupp. [32]

On 14 April 2014 about 200 employees had left Thyssen Krupp for Saab and it was reported that Saab and Thyssen Krupp had started to negotiate about selling Kockums. [33] In June 2014 Thyssen Krupp agreed to sell Kockums to Saab. [34]

On 22 July 2014, it was announced that Saab had bought Kockums from Thyssen Krupp for 340 million SEK. The new name will be Saab Kockums. [35]

On 12 September 2014, Saab Kockums proposed a 4,000-ton variant of the submarines, known as the type 612, for the Royal Australian Navy to replace their ageing Collins-class submarine, however the DCNS entry based on the Shortfin Barracuda class was selected instead.

In December 2014 an agreement between Saab and Damen Shipyards was announced to jointly develop, offer and build next-generation submarines (based on the Type 612 design). [36] Initially focused on replacing the four Walrus-class submarines currently in use by the Royal Netherlands Navy by 2025 combined with the still existing Swedish submarine requirements after cancellation of the previous A26 program.

During a visit to Kockums facilities on 30 June 2015 the Swedish defence minister, Peter Hultqvist, announced that two submarines will be ordered for a cost of 8.2 billion SEK (US$ 956 million). [37] The two submarines were to be delivered to the Swedish Navy in 2024 and 2025. [38] However, in 2021 it was indicated that the delivery date had slipped by a further three years, to 2027–28, and the costs had risen by SEK5.2 billion (or USD600 million). [39]

A26 Blekinge submarines have been offered to Polish Navy as a possible choice for the "Orka" modernization programme which is to be introduced by 2023. [40] [41] [42] [43]

Type 212A submarine Class of diesel-electric Submarine

The Type 212A is a class of diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy, and the Italian Navy where it is known as the Todaro class. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton-exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable.

<i>Visby</i>-class corvette Swedish stealth missile corvettes

The Visby class is a series of corvettes in use by the Swedish Navy. It is the latest class of corvette adopted by the navy after the Göteborg and Stockholm-class corvettes. Its design emphasizes low visibility radar cross-section and infrared signature, and the class has received widespread international attention because of its capabilities as a stealth ship. The first ship in the class is named after Visby, the main city on the island of Gotland.

Type 214 submarine Submarine class

The Type 214 is a class of diesel–electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 submarine family and the features of the Type 212A submarine. However, as an export design, it lacks some of the classified technologies of the Type 212 such as the non-magnetic steel hull that makes it difficult to detect using a magnetic anomaly detector.

The Scorpène-class submarines are a class of diesel-electric attack submarines jointly developed by the French Naval Group and the Spanish company Navantia. It features diesel propulsion and an additional air-independent propulsion (AIP). It is now marketed as the Scorpène 2000.

<i>Södermanland</i>-class submarine Swedish submarine class

The Swedish Södermanland class of diesel-electric submarines consists of HSwMS Södermanland and HSwMS Östergötland. These two submarines were originally launched as Västergötland-class submarines in 1987 and 1990, and were relaunched as a new class after extensive modernization in 2003 and 2004 by Kockums AB. The pressure hull had been cut in two after the sail and a 12 m long new section with an air-independent propulsion system was inserted. It contains two Stirling engines which are coupled to electric generators and heated by burning diesel fuel with liquid oxygen stored in cryogenic tanks. The AIP system can provide electric energy to extend the submarine's submerged time from days to weeks.

<i>Gotland</i>-class submarine Swedish Navy attack submarine class

The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. This capability had previously only been available with nuclear-powered submarines.

Lada-class submarine Russian diesel electric patrol submarines

Lada class, Russian designation Project 677 Lada is the new advanced class of diesel-electric attack submarine designed by the Russian Rubin Design Bureau. A program to develop a "fourth generation" diesel-electric submarine, it aimed to produce a highly improved version of the Project 636 with better acoustic signature, new combat systems and possibly air-independent propulsion. However, in 2019, Alexander Buzakov, the head of the Admiralty Shipyard, indicated that there were no plans to equip the Lada class with an air-independent propulsion system. In July 2022 it was reported that work on an electrochemical generator to produce hydrogen from diesel fuel and oxygen was continuing and that the Rubin Central Design Bureau signed a new contract in 2019 to continue work. This was scheduled to be completed by the mid-2020s. In 2023, the decision was taken to decommission and scrap the lead ship of the class, the Sankt Peterburg due to the very high costs of modernising the submarine.

Viking-class submarine

The Viking-class submarine was a planned class of submarines to be built by the Viking Submarine Corporation. Viking was a corporation jointly established by Kockums in Sweden, Kongsberg Defence & Aerospace in Norway and Odense Steel Shipyard in Denmark. Finland was an observer of the Viking project, as an eventual future buyer of additional Viking submarines. The idea was to develop modern successor to the Swedish Gotland class, that would have cost about one third of the German Type 214. It was initially planned that the Swedish, Danish, and Norwegian navies would purchase two, four, and four Viking-class submarines each starting in 2005.

<i>Sōryū</i>-class submarine JMSDF submarine

The Sōryū-class submarines (16SS) are diesel-electric attack submarines. The first boat in the class entered service with the Japan Maritime Self-Defense Force in 2009. The design is an evolution of the Oyashio-class submarine, from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders. The Sōryūs have the largest displacement of any submarine used by post-war Japan.

<i>Attack</i>-class submarine Canceled Australian submarine class

The Attack-class submarine was a planned class of French-designed submarines for the Royal Australian Navy (RAN), expected to enter service in the early 2030s with construction extending until 2050. The project, which would have replaced the Collins-class submarines, began in 2007 as the Future Submarine program. In 2020 it was estimated to cost A$90 billion and would have been the largest and most complex defence acquisition project in Australian history.
