South Korea plans first nuclear submarine launch by mid-2030s to rival North Korea

South Korea has unveiled its plan to build and launch its first nuclear-powered submarine by the mid-2030s under a new program.

According to Defence Minister Ahn Gyu-back, the new program is designed to counter the growing nuclear capabilities of North Korea, including its submarine-launched nuclear and missile threats.

South Korea’s desire for nuclear-powered submarines is shifting from a long-term aspiration to an immediate policy goal, driven by North Korea’s expanding nuclear arsenal and delivery capabilities.

Seoul is also planning to collaborate with nuclear, shipbuilding and defence industries while exhibiting its commitment not to develop and acquire nuclear weapons.

Equipped with a nuclear propulsion mechanism, the submarines will possess great ability to stay underwater for longer periods and ensure greater mobility than existing submarines.

By increasing survivability and deterrence at sea, these vessels bolster the credibility of Seoul’s conventional defense posture.

The submarines developed under the program will use low-enriched aluminum fuel. These ships will be built in South Korea by closely working with the United States and the International Atomic Energy Agency.

The plan aimed for the first ​vessel to be launched in ​the ⁠mid-2030s, Ahn said.
