South Korea already has 21 submarines

The Korean way to get competence to plan and build their own submarines is textbook. In the 1980s, the Koreans built 3 miniature Dolgorae submarines with only 175 tons of underwater buoyancy. At the same time, negotiations were ongoing on the acquisition of German submarines and their construction licenses in Korea. The choice was on kind 209/1200. The prototype was built in Kilonia at the HDW shipyard, and 2 more of the parts supplied by the Germans at Daewoo shipyard in Okpo, which is already in South Korea. The licence order was then extended by 6 more vessels, which allowed the South Korea MW to enter into possession of a full of 9 proven submarines of 209/1200 designated as KSS-I or kind of Jang Bogo (SS 061) from the name of the first unit built in Germany.
