The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockumsshipyard in Sweden. They are the first submarines in the world to feature a Stirling engineair-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. This capability had previously only been available with nuclear-powered submarines. Read More on Wikipedia.
