The Gotland class attack submarines of the Swedish Navy are modern diesel-electric submarines. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to two weeks.[1] This capability has previously only been available with nuclear powered submarines.
