South Korea Advances Nuclear-Powered Submarine Program Amid North Korean Threats

• •South Korea's DAPA approved the Jang Bogo N nuclear submarine project on November 6, 2026.
• •The project aims to enhance military capabilities against North Korea, with submarines operational by the late 2030s.
• •The total estimated cost for the submarine program is around 28.9 trillion won ($21.3 billion).

On November 6, 2026, South Korea's Defense Acquisition Program Administration (DAPA) approved the basic plan for the Jang Bogo N nuclear-powered submarine project, aimed at enhancing military capabilities against North Korea's nuclear threats. The project, exempt from a preliminary feasibility study, will formally launch in 2027, with the first submarine expected to be operational by the late 2030s. The submarines will utilize small modular reactors for propulsion, following U.S. approval for low-enriched uranium fuel. The total cost of the program is still under deliberation, but estimates suggest it could reach approximately 28.9 trillion won ($21.3 billion). Additionally, DAPA approved a tactical missile project to counter North Korean artillery, scheduled from 2028 to 2035. The developments are part of South Korea's broader strategy to strengthen deterrence against North Korea's expanding military capabilities.
