Saab designs, builds and maintains advanced non-nuclear submarines for operations in both extreme littoral zones and blue waters. Leading technology built into these vessels include our innovative Air-Independent Propulsion (AIP) system based on the Stirling engine.

Stirling AIP eliminates surfacing for regular battery charging, and our submarines can therefore remain under water for weeks rather than days. This, in combination with superior stealth technology, extreme shock resistance and a powerful combat system, make Saab's solutions exceptional non-nuclear submarines.
