North Korea’s state media, the Korean Central News Agency, has depicted leader Kim Jong-un unveiling a new nuclear attack submarine named ‘Hero Kim Kun Ok.’ The regime claims the submarine is designed to launch tactical nuclear weapons from underwater. Tactical nuclear weapons typically have a lower yield than conventional atomic weapons and are used in scenarios where friendly forces are in close proximity to the target. South Korean officials remain skeptical about the capabilities of the submarine and believe it is not yet ready for operational use. However, the development highlights North Korea’s ongoing efforts to expand its nuclear arsenal with systems that are harder to detect in advance.
The submarine, which was likely based on modified 1950s Soviet-origin technology, has at least ten launch tubes, four of which appear to be larger than the other six, possibly designed for missiles. North Korea has been testing various missiles designed for submarine use in recent years as it seeks to establish a survivable capability for retaliatory nuclear strikes from underwater.
Satellite images indicate that the submarine and the unveiling ceremony took place in the eastern port city of Sinpo, where North Korea operates a significant shipyard focused on submarine development. Kim Jong-un is also reportedly preparing to visit Russia for discussions with President Vladimir Putin, possibly involving North Korean arms sales to replenish Russian supplies depleted by the war in Ukraine. In exchange, North Korea may seek economic aid and advanced weapons technologies from Russia.
This development adds another layer of complexity to regional security concerns and underscores North Korea’s commitment to advancing its nuclear capabilities.
