    Submarine Type A26

    [​IMG]

    The Swedish Government has approved initiation of the design phase for a new generation submarines for the Royal Swedish Navy.

    Next generation submarine type A26
    The new generation, denominated A26, will be designed for mainly littoral operations but will also possess ocean-going capabilities. It will be powered by a conventional diesel-electric propulsion machinery, and equipped with Kockums Stirling AIP system (air-independent propulsion). The Stirling system, together with a set of balanced underwater signature properties, will make the A26 submarine very stealthy and difficult to detect. It will also be highly invulnerable to underwater explosions through a verified shock resistance.

    The A26 design includes a new innovative flexible payload capability with a flexible payload lock system in addition to its conventional torpedo tubes. Furthermore it will be prepared for network connectivity. A highly modular design facilitates efficient through-life upgrades and adaptations.

    Kockums Receives Design Order for Next-Generation A 26 Submarine


    (February 25, 2010) -- Kockums AB, part of ThyssenKrupp Marine Systems, has today signed a contract with FMV (the Swedish Defence Materiel Administration), concerning the design phase of the next-generation submarine, known as A 26. This confirms the intention to develop Sweden's submarine capability. Kockums is prime contractor for the order.

    The Supreme Commander of the Swedish Armed Forces has emphasized the importance of acquiring the next-generation A 26 submarine on a number of different occasions.

    The next-generation submarine features several advances in the development of underwater technology and marks the adaptation of submarines to meet current and future threats and to conduct the international mission now required. This refers particularly to the submarine's role as an information gatherer. Next-generation also refers to further refinements in terms of stealth technology. The submarine will be able to see and hear everything over a wide area, while itself remaining undetected. A 26 will be designed to be efficient in the Baltic and other littoral waters.

    "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. HMS Gotland demonstrated what she is capable of during two years of joint exercises in the water off the USA. This next-generation submarine marks a further refinement of technology", states CEO Ola Alfredsson, commenting the news.

    Kockums to Design Sweden‘s Next-Generation Submarine


    Sweden‘s A26 Submarine Programme to Enter Next Phase after Government Approval

    10:01 GMT, February 26, 2010 defpro.com | Following last week’s approval by the Swedish government to initiate the design phase, the country’s Defence Materiel Administration (Försvarets materielverk, FMV) awarded Kockums AB, a 100% subsidiary of ThyssenKrupp Marine Systems, with a contract for the overall design of Sweden’s next-generation submarine. This decision is seen as confirming the government’s intention to further develop Sweden’s submarine capability, after the programme was delayed and failed to be carried out as a multi-national Scandinavian procurement programme, as was originally planned. Initiation of the design phase for the submarines, designated A26, was previously approved by the Swedish government in December 2007.

    Several years ago, Sweden was involved in talks with Norway and Denmark, within the framework of the so-called “Viking” project, to build a tri-national next-generation submarine. However, after Denmark decided not to operate any submarines in the future, Norway also left the project and it continued on as a national programme. Nevertheless, Norway has shown continued interest and is examining a possible future purchase of the submarine. For the time being, this remains an exclusively Swedish programme, which so far is intended to provide two submarines for the Swedish Navy, as confirmed by Ulf Lindström, Press Relations Manager at the FMV. However, the final number of next-generation submarines to be procured has not yet been decided by the government.

    Commenting the order for the overall design, Kockums CEO Ola Alfredsson said: “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 light of the current threat scenarios. HMS Gotland demonstrated what she is capable of during two years [June 2005 - July 2007] of joint exercises in the waters off the USA. This next-generation submarine marks a further refinement of technology.”

    According to Kockums, the naval capabilities of the new generation will focus on littoral operations, however, without abandoning its significant ocean-going capabilities. It will be powered by conventional diesel-electric propulsion machinery and will be equipped with Kockums Stirling AIP system (air-independent propulsion). The latter have already been successfully operated with Gotland-class submarines, which made them most interesting to the US Navy, which leased a Gotland-class vessel for naval exercise purposes. The Sterling AIP system, combined with a set of balanced underwater signature properties, makes the submarine very difficult to detect and allows it to stay submerged for weeks. Furthermore, Kockums will also attempt to create a design that will be highly protected from underwater explosions through verified shock resistance.

    Ulf Lindström further commented on the capabilities of Sweden’s future submarines: “The submarine will, among other new features, be equipped to support Special Forces operations as well as the future use of autonomous or remotely controlled underwater vehicles.” The submarine, which is intended to provide a high degree of modularity, “is also optimised for efficient production using large, resiliently mounted platforms and a highly modular interior,” explained Lindström.

    A key element in the future operations of the submarines will be information gathering, as Kjell Göthe, Senior Vice President PR & Communications at Kockums, told defpro.com. The combination of sensors and noiseless propulsion will enable the submarine to see and hear everything over a wide area while remaining undetected.

    As Mr Göthe said, the recently awarded design contract, which will be implemented during the next two years, is an important success for Kockums and supports the further sustainment and development of Swedish expertise and know-how in the field of naval development and construction. The government is scheduled to make a decision on the building phase in spring 2010 and is aiming at 2017 for the launch of the first vessel.


    Key data* of the next-generation submarine (A26):

    • Length: 63m (ca.)
    • Pressure hull diameter: 6,4m (ca.)
    • Two pressure tight compartments

    • Displacement:
    - Surfaced:1,700 m³ (ca.)
    - Submerged: 1,860 m³ (ca.)

    • DE-Gensets: 3 x 500 kW
    • Stirling AIP system Mk III: 3 x 65 kW
    • Crew size (mission dependent): 17-28

    That would be... Quoi? or Comment? not Que?

    Never had an export except a lease to the USN to use as target practice. What is it with you Swedes and leases? You lease your best submarine then you lease your best fighters. Sure do take alot of risks not being a NATO member.

    Well, in that case Rafale is also "ill fated", though it is still an exellent fighter (like Gotland is an exellent submarine).

    The americans never found it, that's why they leased it twice. It should be noted that they also leased the entire crew, so they didn't "dig around" in it if you know what I mean. The whole lease worked both ways, we got to play against the american navy with aircraft carriers and such wich gave us some experience as well.

    The new A26 will probably do well in exports since there is another country involved in the project. It will be a properly good submarine.

    Rafale has often been refered that way. But it won't be by this time next week.

    The Americans found it several times after the Reagan was photographed. They exercised with it for two years.

    Perhaps, it will surely do better than the Gotland class.

    Sweden to invest in new submarines

    Published: April 11, 2010, 04:33

    NEW SUBMARINESYSTEM The Government gives notice of the spring budget to buy two new submarines and renovate two more. This is a multi-billion investment that will ensure that the Swedish submarine fleet also continues to maintain the highest class, writes Defence Minister Sten Tolgfors.

    Before comprehensive defense reform, which was due-in last spring's orientation bill, had the national response organization too low usability and accessibility for today's needs. It was built on an increasingly hollowed out military service and was useful only within the country. The defense had a particular employee strength abroad, for military operations far away. But the defense of Sweden and international efforts, it was a backlash.

    Defence policy had long lacked a clear perspective for the region - the Baltic, Scandinavia and Europe.

    With the defense reform, we now have a standing bet with the organization and contracted joints based on voluntary recruitment, with high availability and usefulness to the defense any information. The task is to defend our country and our country's interests, whether carried out in the country, except in the neighborhood or the neighborhood, alone or with others.

    Sweden will also be able to have a stabilizing effect in the neighborhood. Conflicts should be prevented from coming to us. The design and orientation of the Swedish military is given a clear conscious and neighboring Baltic profile.

    Sweden has northern Europe's largest and most advanced air force. It is twice as large as our neighbors. It has analyzed the recent modern war understand the importance of air supremacy. The Air Force monitors the air space and represents a threshold for a hostile action against Sweden. To balance the Gripen system purchased now links 16 for Modern and interoperable command, and a new radar missile.

    Together with Finland, Sweden initiated and over the last year built a common Baltic Sea monitoring. The cooperation has broadened and eight countries now share civilian and military sjölägesinformation in SUCBAS, creating an entirely new global picture of what's happening in the Baltic Sea.

    The background to the cooperation in the Baltic Sea is that every moment of sailing ships 2000-3000. Oil transports on the Baltic Sea has doubled in size and growth will continue. The Baltic Sea is an equally sensitive, as for commerce and communications is important, ocean. Therefore, the implementation at this time also the Coast Guard a greater number of new vessels and surveillance aircraft to monitor and respond to future challenges.

    Baltic Sea region is stable, as the Baltic Sea is bordered by the EU and NATO countries, Kaliningrad and St. Petersburg areas are excluded. However, you can never rule out long-term risk of crises and incidents, which may also be military in nature.

    Sweden has a fleet of five new Visby corvettes, which gradually becomes operational, and with an advanced submarine conducting surveillance of the Baltic Sea, and below the surface. This represents a threshold of hostile action. Fleet focus, like air traffic, primarily for neighborhood information. There is no actor in the neighborhood that now have the ability or willingness to land in such a skilled opponent.

    The Swedish conventional submarine force is absolutely world class, which was verified, including the export to Singapore and a large American interests to practice with the Swedish submarines and very good Swedish results of these exercises.

    In recent years the government has worked to prepare a major substantive renewal of the submarine force. The next generation of submarines has been prepared by a progressive decision-making, until the completion of an educa, then a design phase for the preparation of drawings and specifications. Through this we can be confident that a sustainable basis for decision is arrived.

    The government will therefore be in the spring budget to propose the following:

    • Next-generation submarine, NGU, built and acquired. Sweden therefore decided now to buy two new submarines, which is expected to be added to the Armed Forces 2018/2019. They will replace two of Södermanland class submarines.

    • Two pieces of Gotland Class submarines will get Mid-Life Update maintaining operational effectiveness.

    Decisions regarding these submarines of the Gotland Class life extension until 2035, or replaced by additional purchase of new submarines, predicted thus have to be taken around 2020.

    This is a multi-billion investment. This significant substantive renewal of submarine force ensured that the Swedish submarine fleet will continue to maintain the highest international standard. It also secures the unique technical skills in Sweden, and highlights the new Baltic and neighboring perspective of security policy.

    Most likely, the new submarine systems that Sweden now procure to meet great interest from other countries, with potential export business as a result.

    A modern submarine weapon is perhaps the most effective way to secure our country against external threat of a widespread nature. Modern submarines have an excellent collection and monitoring capabilities, and is a major obstacle for any actor who wants to use the Baltic Sea other than for peaceful shipping.

    The new submarines, which the alliance will raise our decision because at the heart of the defense of Sweden.

    Tolgfors (M)

    Defense Minister

    This can be a good option to the failed scorpene program which has produced nothing but delays and cost overruns and endangered our conventional sub program.

    If the A26 turns out to be better than the Scorpene and the German Type 214, which I think it might, then I think the IN should consider it for our future requirements !!
     
  15. i think india should try to build submarines like sweden both nuclear and diesel powered in large numbers in the next two decades given the conventinal submarine superiority which china possess in terms of submarines over india.china has around 62 submarines of which 10 are nuclear.we have 16 old conventinal submarines of which 7 are to be retired in the next 5 years.we should try to build china like military capacities
    in all spheres by 2030 given by that time frame China will cross US in terms in terms of gdp and try to manipulate all our foreign policies like us does today.

    There is no doubt about China doing that. But India cannot try to keep balance in South Asia by itself. China is one big power........
    We don't spent nearly as much as China on defense.

    We should develop indigeneously.... ALL PARTS. Not even like Tejas where Radar from Israel, Engine from Europe, NO NO NO. Everything indigenous will make the projects cheap, and no delays!

    New super-submarine for the Swedish Navy | SSPA

    New super-submarine for the Swedish Navy

    The Swedish Navy will invest in A26 – the new super-submarine – scheduled to be operational in 2018. The submarine will be specially built to operate submerged for several weeks. It has a large lock in the bow with the ability to lock in and out divers and unmanned underwater vehicles without having to surface. This unique feature of A26 will become a universal gateway for many different types of operations avoiding the submarine to be exposed on the surface. SSPA has performed the hydrodynamic investigations for the A26.

    The main mission of the A26 is gathering intelligence but with the ability to respond quickly and forcefully to any threat. It will be able to explore the area using remotely operated underwater vehicles and will have a very strong protection against shocks and underwater explosions. These qualities are suitable not only for military operations, but also for tasks like fighting drugs and weapon smugglers.

    Under contract with Kockums, SSPA have been developing the hydrodynamics and propeller design of the new Swedish A26 submarine. SSPA have performed the model testing on a scale model that has been manufactured and equipped with propeller, active aft control surfaces and forward hydroplanes. With autopilot engaged, the submarine model is free-sailing.

    Model testing will be performed at all three major SSPA facilities:

    the towing tank
    the cavitation tank
    the sea keeping/maneuvering basin

    SSPA have investigated the speed-power performance as well as designed the propeller and validated its performance. Further SSPA have developed a virtual maneuvering simulation model of the submarine to test its maneuvering performance, for example turning radius, depth changes and emergency flooding recovery.

    SSPA has been involved in hydrodynamic development work for submarines since 1940. During this period SSPA has been involved in development and testing of all classes of Swedish submarines. The work includes model scale and full scale tests amounting to a total of well over 600 studies. SSPA has also performed submarine testing for several other European countries as well as for the Australian Collins class submarines.
