The Gotland -class submarines of the Swedish Navy are modern diesel-electric submarines , which were designed and built by the Kockums shipyard (since 2014 owned by SAAB AB ) 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 .

SwedenNavy exact named Gotland mod (fitted with AIP) component holdings; active, operational-reserve and training equipment excluding equipment in store, except explicit status exclusions stated below. November 2025 IISS assessment. Named service only, not a national total or combat-readiness measure. Source armament/capacity counts are excluded. Modified and AIP are source configuration qualifiers of the exact Gotland class; no Västergötland, Stirling-unit count or new submarine design is inferred.
