The Gotland Class refers to a series of submarines used by the Swedish Navy. These submarines are known for their advanced stealth capabilities, allowing them to operate undetected in various maritime environments. They are designed for anti-submarine warfare, anti-surface warfare, and intelligence gathering. The first submarine of this class, the HMS Gotland, was commissioned in 1996. The Gotland Class features a unique air-independent propulsion system, which enables them to remain submerged for extended periods without surfacing. This technology enhances their operational effectiveness and makes them a vital asset for Sweden's naval defense.
