The Korean People's Army Naval Force (Korean: 조선인민군 해군, Hanja: 朝鮮人民軍 海軍) is the navy of North Korea. The Korean People's Army is made up of the Ground Force, the North Korean Air Force, and the Navy. It was established on June 5, 1946. The navy strength in the 1990s was about 40,000 to 60,000; current strength (2008) is at about 46,000. There are some 708 vessels including 3 frigates and 70 submarines: approximately 20 Romeo class submarines (1,800 tons), 40 Sang-O class submarines (300 tons) and 10 midget submarines including the Yono class submarine (130 tons).

The North Korean navy is considered a green-water navy and operates mainly within the 50 kilometer exclusion zone. The fleet consists of east and west coast squadrons, which cannot support each other in the event of war with South Korea. The limited range of most of the vessels means that even in peacetime it is impossible for a ship on one coast to visit the other coast.
