Submarine Type A26.
Kockums AB, part of ThyssenKrupp Marine Systems, has signed a contract with FMV (the Swedish Defence Materiel Administration), for the design phase of a next-generation submarine, to be known as the A 26 class.
The A 26 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, the Swedish shipbuilder says. “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,” the company says.
The submarine will be designed to be efficient in the Baltic and other littoral waters, but will also have an oceangoing capability. “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,” says CE Ola Alfredsson. “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”, he adds.
The boat will be powered by a conventional diesel-electric propulsion machinery, and equipped with the 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 higly invulnerable to underwater explosions through a verified shock resistance.
The A 26 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.
The successor of the Gotland class (A19), the new sub is developed under the name A26 with the same deplacement but built with flexibility and international missions in mind. The nordic VIKING Project is dead, the A26 project is therefore ordered by the Swedish military. The yard Kockums is in talks with up to 3 other nations (Singapore mentioned) in participation to cut the costs of the development of next generation subs.
The catchphrase for the project is (when translated)
"Longer, Faster, Efficient"
The major design changes:
Added stealth features in notably the hydrophone area
Flexible load-up of number of crew (17-31) and equipment. (elint, special ops, traditional attack sub, information superiority, network based command centre etc)
Ocean longivity, faster speed, longer range.
Reduced maintenance, less logistics. More hours at sea.
Machine gun 25-30mm (optional, likely a RWS)
Personell protection, rubber shock protection
Autonomous underwater vehicles
Latest version Sterling AIP propulsion.
Requirement to move 1000's of nautical miles, stay in that area for weeks, and return. Transit speed ocean (sweden-usa and back) 9knots, normal operational speed submerged 20+, surfaced 10+.
Length over all 63 m
Beam 6.4 m
Displacement 1900 tons submerged
Weapon armament Four 53 cm bow tubes + one flexible payload lock
Weapons Positive discharge or swim-out
Propulsion Single-shaft, diesel-electric and Stirling AIP
Submerged endurence Weeks
Hull Single pressure hull, two pressure tight compartments
A26 with deployed UUV sensors that can swim up rivers etc.
The current demand is for 5 subs (yet to be contracted). Source: FMV, Protec 0601.

One Gotland sub is currently in the USA.
