  • South Korea plans to build its first nuclear-powered submarine by the mid-2030s.
  • The initiative aims to counter North Korea's submarine-launched nuclear threats.
  • The U.S. supports South Korea's nuclear submarine development amid regional tensions.

South Korea has unveiled plans to develop its first nuclear-powered attack submarine, expected to be operational by the mid-2030s. This initiative, named the Jangbogo-N Project, aims to enhance South Korea's naval capabilities in response to North Korea's advancing submarine-launched nuclear and missile threats. Defense Minister Ahn Gyu-back announced the project during a meeting at the naval base in Jinhae, emphasizing its strategic importance. The submarines will be built domestically and are designed to significantly improve operational capabilities compared to existing diesel submarines. The U.S. has endorsed this initiative, promising support in building the vessels, although there are discussions regarding the construction location. The project has been in consideration since the early 1990s, and experts note that it reflects a broader arms race in Northeast Asia, involving China and Japan as well. Challenges remain, including technology transfer, nonproliferation concerns, and industrial capabilities.
