HNLMS K XVI was one of five K XIV class submarines built for the Royal Netherlands Navy (RNN). Entering service in 1934, the submarine was deployed to the Netherlands East Indies. On 24 December 1941, K XVI torpedoed and sank the Japanese destroyer Sagiri; the first Allied submarine to sink a Japanese warship. A day later, the Dutch submarine was torpedoed by Japanese submarine I-66 off Borneo, with all aboard killed. The wreck of K XVI was rediscovered in October 2011 by a group of recreational divers.
