At the leading edge of submarine technology - Kockums

To see…The Maritime Security ConceptThe Maritime Security Concept is Kockumscontribution to greater efficiency in protectingterritorial waters from new types ofthreat. These threats could include terrorism,military action, smuggling, non-conventionalweapons and the impact of religious or politicalconflicts. The concept embraces a numberof threat scenarios and possible responses,usually comprising submarines, remotevehicles and surface vessels, e.g. for patrolduties, minesweeping, minehunting.5

Whatever your needsFull systems integration – standard or customisedOn a submarine, a whole range of systems must be integratedto ensure optimal function. Kockums is highly experienced inthis type of integration, whether it involves existing standardsystems, customer-specific solutions or a combination of thetwo. Our goal is to create a submarine that can play a naturaland active role in a broader context, at both the national andinternational level. In other words, a submarine that is fully integratedwith other units at sea, on land, in the air and in space.HumansAuxiliaryDesignSignaturesEnergyControlPayloadControl, Command and ComputerThe tactical data management system, optimisedto meet your special requirements,handles the acquisition, processing and presentationof data, such as threat evaluationand attack planning for weapons engagement.We are also experienced in all typesof intelligent navigation systems, fromterrestrial navigation to three-dimensionalinertial-navigation systems.8CommunicationThe quality of a submarine’s communication systemsis decisive to its ability to respond faster,more safely and more efficiently. Kockums, withbroad experience of integrating such systems,has succeeded in uniting the most advanced technologywith extreme clarity and a user-friendlyinterface. Our experience includes:• Continuous and real-time communication• Optical fibre cable• Wide Area Network NodeSensorsWe integrate and install advancedsensor systems onboard or sensors thathave been deployed or recovered, usedfor detection, tracking and classificationof targets.• Passive and active sonars• Optical and infra red sensors• Electric and magnetic field sensors• Sensor data fusion

We build and integrate itIntegration of unmanned vehiclesThe Kockums Concept features the integrationof unmanned underwater combat vehicles for:• Persistent high-risk area surveillance• Weapons engagement• Countermeasures (jamming/decoys)Torpedoes, mines and missilesSeveral wire-guided torpedoes can belaunched simultaneously. A submarinecan also deploy, maintain and recovermines while remaining hidden, andcan be equipped with various typesof missile.Replenishment in a couple of hoursReplenishment of utensils is swift and easilyperformed both ashore and at sea without specialfacilities or equipment.It embraces e.g.:• Cryogenic liquid e.g. Oxygen and Helium• Weapon• Fuel• FoodTransfer your investmentsOur vessels are built to facilitate theintegration and installation of differentsystems. Conversely, this makes itequally easy to transfer earlier investmentsin the form of combat command,navigation and sensor systems to a newsubmarine, when the original vessel hasreached the end of its service life.9

Proven concepts from Kockums Add Stirling AIPThe Stirling AIP (Air Independent Propulsion)system is the most widely operatedpropulsion system of this type. It extendssubmerged endurance from a few daysto several weeks, a capability previouslylimited to nuclear powered submarines. It isvibration-free, silent and virtually undetectable.Stirling AIP successIt was in 1988 that Kockums installed theworld’s first AIP system for a conventionalsubmarine. This system has now loggedthousands of hours with its AIP system.From a very early stage, the technique hasproved highly successful as an auxiliarypropulsion system for submarines up toseveral thousands tons.Upgrade to Stirling AIPVirtually any conventional submarinecan be upgraded to Stirling AIP standard.The submarine is cut in two and an additionalfully-fitted AIP section is inserted.10

This has involvedfitting completely new refrigeration systems andclimate control system.We added a Stirling AIP sectionThe submarines have been lengthened by insertinga Stirling AIP section. This section, fully fitted andequipped prior to installation, contains several Stirlingunits, liquid oxygen tanks and electrical equipment.Consequently, all operational submarines inthe Swedish fleet now have Stirling air-independentpropulsion – unique among navies equipped withconventional (non-nuclear) submarines.Smarter and stealthierThe Command, Control, Computer, Communicationand Intelligence systems (C4I) of the Södermanlandclass have been upgraded to the latest standards andthe boats’ stealth capabilities are being further refined.The submarines have also been equipped with anew airlock for divers.Can operate in warmer watersAn important aspect of the Södermanland classupgrade programme is that the vessels are nowequipped for international peacekeeping missions in18

Viking class submarine (type A24-28) (SSK)The submarine for the 21 st centuryTechnical dataDisplacement 1 100 - 1 700 tonsLength 50 - 60 mBeam 6-7 mPropulsion Stirling AIP and diesel-electricCrew 20 - 30The Viking submarine is the outcome of a feasibilitystudy and conceptual design conducted by Kockumsfor the Viking Project Group. The mission was todevelop a submarine concept that combined and integratedthe operational requirements of several differentnations, while also meeting joint performanceand cost-efficiency demands. The winning concept isa modular design and construction techniques, whichgive the submarine increased flexibility, specially inthe area of flexible payload and consequently beingadaptable for new types of mission.More stealthUtilising Kockums advanced modular constructiontechniques, the Viking submarine incorporates substantialadvances in stealth technology. The CombatManagement System suite features state-of-the-artC4I (Command, Control, Computer, Communicationand Intelligence) functionality. Specially enhancedcommunication with much more Net Centric Warfarecapabilities.Extended Air independent PropulsionImproved AIP performance will enable the submarineto remain submerged for greatly extendedperiods of time, invaluable in peacetime or conflictscenarios.Increased sensors rangeFrom a full suit of improved sensors with optimisedshape in combination with extremely sophisticatedsignature adaption and management systems.19

Poised forDevelopment of the custom-made conceptWe intend to make the next generation of submarines an internationalproject through cooperation with potential client countries. Thisdemands a flexible design concept that meets the differing operationalrequirements of individual countries. Demands that future submarinesfunction as an integral part of large networks will also increase. Heretoo, Kockums has already taken a leading role in the field.Further refinement of stealth technologyKockums is devoting considerable resources to refining thestealth properties of submarines, in collaboration with universitiesand other institutions. Hull shape, the materials used andacoustic damping are important aspects of this commitment.Radically new designs are under development. For example,a micro-sub launched and controlled by the mother vessel,and which is extremely hard to detect, is being developed tosupplement the submarine’s own sensors. The micro-sub detectsdifferent types of signal and undertakes visual reconnaissance,while the mother ship waits at a higher and safer depth.20

the futureSurvive a direct hitKockums is currently engagedin advanced research into thestrength of submarine hulls. Inthe near future, new technologywill enable submarines tosurvive even a direct hit bymodern conventional weapons.Fourth-generation AIP systemContinuing development of this silentpropulsion system will further enhancethe stealth capabilities of submarines,virtually eliminating the need to surfaceduring combat patrols.Depending on operational requirements,next-generation submarines arelikely to employ an AIP system as theprimary source of propulsion.Modelling and simulationKockums has developed advanced simulation and modellingprogrammes for cost-efficient and realistic developmentof submarine systems and crew training.Sensors, command and weapon systems are alsoundergoing steady improvement and refinement.Systems integration and advanced sensors, combined withKockums long experience and advanced construction technology,will ensure that our next-generation submarinesgive operational efficiency a whole new meaning.21

KockumsLooking forward to our centennial celebrationTradition of innovationKockums received its first submarinecontract in 1912 and the two 252-tonne“Svärdfisken” and “Tumlaren” submersibleslaunched in 1914 marked the start ofthe company’s highly successful developmentof several generations of conventionalsubmarines. Since then, Kockumshas been intimately involved in developingsubmarine fleets into efficient andpowerful forces. Kockums has designedmany submarines and, since the end ofthe Second World War, has developed agreater number of submarine classes thanany other shipyard in the world.Joint approach – an important stepforwardKockums is a full subsidiary of therenown German shipyard Howaldtswerke-Deutsche Werft AG, thus belonging to theHDW Group which has shipyard locationsin Germany, Sweden and Greece. Thegroup’s headquarters are in Kiel, Germany.The excellent position held by the HDWGroup is largely the result of success innaval shipbuilding. The merger of theshipyardshas further strengthened theirleading position among internationalsubmarine builders.
