This is a List of active ships of the Korean People's Navy, the naval service of North Korea. Most of the list includes Ships of Korean Origin. Yet, it also contains types that are less frequently used, with their origins from past communist countries of the Soviet Union, and China. In late years, the production of lightly armored, but yet mobile and maneuverable small PT Torpedo Boats increased, as well as Patrol and Landing Craft used in case of National Emergency. Submarines, on the other were costly, hard to manufacture. The Corvettes of the Korean People’s Navy were all outclassed by the 2000s and new ones are still under way.
