World leading submarines

Saab business area Kockums is a world leader in the construction of submarines.

Technological development is an ongoing process at every phase of the construction of a submarine. That is reflected, among other things, in the high-tech A26 class project. These submarines have an optimum and balanced underwater signature, which means they are almost impossible to detect. The technology used by Saab is likewise used in larger conventional submarines of the Collins class (Australia) and the Soryu class (Japan). This makes it the ideal partner for the design and construction of expeditionary submarines for the international market.

Submarines setting new benchmark

The first submarine built by Saab Kockums was launched in 1914. Since then Saab Kockums has delivered more than 70 submarines to the RSwN, and has been their prime supplier of submarines since the 1960s. There has been a more or less continuous development with a new submarine class every 10-15 years and currently Saab Kockums is contracted by the Försvarets materielverk (FMV, i.e. Swedish Defence Materiel Administration) to deliver two new submarines of the A26 class and is also undertaking a mid-life upgrade of two Gotland Class submarines.

We have also designed and supported the construction of the six Collins class submarines for the Royal Australian Navy. During this contract the infrastructure for construction and supporting submarines in Australia was also built up.

Furthermore, Saab Kockums has delivered modernised Swedish submarines, the Challenger Class and Archer Class to the Republic of Singapore Navy, including training packages and submarine fleet establishment support. Also, Saab Kockums has exported Stirling AIP systems and technology to Japan.

The upgrade of Gotland-class submarines The Gotland-class submarines HMS Gotland and HMS Uppland have undergone comprehensive mid-life upgrades. This is our evolutionary way of creating a new breed of submarines by adding new capabilities to already renowned underwater vessels – a century of experience continues to pave the way for our future submarine programme.

Oceanic range submarines

Oceanic is Saab’s submarine cornerstone. Based on a revolutionary, forward-thinking design and more than 100 years’ of experience. Examples of submarine models in the oceanic range are the Södermanland-class, the Gotland-class and the – currently under production - Blekinge-class (A26) submarines.
