Swedish submarine HSwMS Uppland (S71) docked alongside auxiliary vessel HSwMS Visborg (A265).
The Gotland-class submarines of the Royal Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. 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 weeks. This capability had previously only been available with nuclear-powered submarines.
