Submarines

Saab’s submarines are based on generations of evolutionary design. Building on more than 100 years’ experience, 7 submarine classes have been delivered across 3 continents.

Acting undetected – the ultimate defence asset

Submarines are unique tools for securing national interests. In a world where any movement or asset is exposed, being able to act undetected has never been more crucial. Submarines play a vital role in a wide range of naval operations and tasks, from peacekeeping to warfare operations, in both offensive and defensive roles. Submarines can perform national missions that no other asset can. To meet diverse, international requirements across a large spectrum of missions, we offer conventional submarines that address three market segments: Pelagic, Oceanic and Oceanic Extended Range (XR). The segments are based on a mix of size and technological complexity. By combining a unique range of capabilities, state-of-the-art stealth technology, Air-Independent Propulsion (AIP), high endurance, versatile combat system suite and various weapons, we have created shock-resistant, modular designed submarines for maximum operational flexibility.

Future-proof modular design

Saab submarines are offering a flexible approach, meeting various needs of different navies thanks to modular design. This flexibility is also securing upgrades and modifications, making the submarines future-proof over time. Modules are designed depending on operational and tactical needs. Equipment installations can be easily accessed for maintenance and upgrades at any point in the submarine’s lifecycle.

Saab submarines are customisable thanks to modular design, which future-proofs operational flexibility over time.

Saab offers conventional submarines that address three market segments: Pelagic, Oceanic and Oceanic Extended Range. Saab’s submarine range includes larger and smaller submarines designed for an adapted variety of missions and requirements.

Pelagic

Saab’s Pelagic segment refers to our smaller submarines, adapted for long-range missions in narrow or littoral environments. Highly manoeuvrable with high speed and a large weapon load, these submarines represent a dangerous threat to any opponent. Pelagic submarines have a lower acquisition price and operating cost and can also be offered with the Stirling AIP technology for superior submerged endurance.

Oceanic

Throughout our history we have continuously developed our submarines. The leading product in the Oceanic segment is the Blekinge-class submarine, currently in production for the Royal Swedish Navy. Its modular design and production method allows the submarine to accommodate a larger and more versatile suite of weapons, various crew sizes, highly efficient AIP systems and a Multi Mission Portal^tm, significantly increasing the operational scope.

Oceanic Extended Range

Submarines in the Oceanic Extended Range (ER) segment are the largest in the series, designed for much longer missions, greater crew size and increased weapon payload capability. Oceanic ER submarines enable long-distance operations, suitable for any navy using forward deployment of their submarines on extended missions.

Our products

Here's our offer within 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.
