South Korea plans to launch its first nuclear-powered submarine by the mid-2030s under a new defence programme. The project aims to strengthen Seoul’s military capabilities against North Korea’s growing missile and submarine threats. The announcement signals a major shift in South Korea’s long-term naval defence strategy.
Defence Minister Ahn Gyu-back revealed the plan on Tuesday while outlining efforts to improve maritime security capabilities. He said the submarine programme would help counter North Korea’s submarine-launched nuclear and missile systems. South Korean officials believe advanced naval assets are becoming increasingly important amid rising regional tensions.

The announcement came shortly after North Korea reportedly fired several missiles, according to South Korea’s military. The launches added to growing concerns over Pyongyang’s expanding weapons development programme. Seoul and its allies have repeatedly warned about North Korea’s continued missile testing and nuclear ambitions.
A nuclear-powered submarine would allow South Korea’s navy to operate longer without surfacing for refuelling. Military analysts say such submarines provide greater stealth, endurance, and strategic deterrence capabilities. Several regional powers, including the United States and China, already operate nuclear-powered submarine fleets.
