A historic vessel
Built in 1925 for the Royal Netherlands Navy, K XI was one of the first submarines designed for long-range patrols in the Netherlands East Indies (NEI). During World War II, the vessel was relocated to Fremantle, Australia, where it played a role in Allied submarine operations in the Pacific theatre.
