The Gotland-class submarines of the 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.

The F class submarine was built for the Royal Navy as a coastal submarine based on the doubled hulled V class submarine (World War I) with very few minor improvements. The only important improvement was the addition of a stern torpedo tube. The F class were ordered as a successor to the E class submarine, but only three were built out of the ten ordered, the first F1 at Chatham. During World War I, the F class submarine was primarily used for coastal defence. All three survived the war and ended their service as training boats at Campbeltown. F1 and F3 were scrapped in 1920, F2 was sold in 1922.
