South Korea launches Jang Bogo-N roadmap for nuclear-powered attack submarines

South Korea has formally adopted a national plan (Jang Bogo-N) to develop and field nuclear-powered attack submarines using low-enriched uranium, long-cycle reactors, and a vertical-launch missile section. The concept also highlights potential advanced features (rim-driven propulsor, AI combat management, electro-optical mast, manned-unmanned teaming), indicating a significant capability shift from diesel-electric boats toward longer endurance and wider-area operations.
