Furusund (ARS)

HMS Furusund (A320) is a specialized diving support and submarine rescue vessel operated by the Swedish Navy. Originally constructed as a multi-role minelayer, the ship was later extensively modified to support underwater salvage, diving operations, and submarine rescue missions. It features specialized equipment including decompression chambers and support systems for unmanned underwater vehicles.

HMS Furusund was built by the Åsiverken shipyard in Åmål, Sweden, and entered service with the Swedish Navy in 1983. Designed during the Cold War, it initially served as a minelayer before being converted to meet the navy's growing need for dedicated diving and submarine rescue support. The vessel underwent a comprehensive mid-life upgrade in 2015 to extend its operational lifespan and modernize its onboard systems. It remains in active service, supporting Swedish naval operations and underwater search and recovery tasks.
