Autonomous Systems: Land & SeaBackground
Jangbogo-N is South Korea's planned nuclear-powered submarine, also designated KSS-III Batch-III. The 179th Defense Project Promotion Committee approved its basic strategy on 6 November 2026.
The project begins in 2027. The lead boat is due by the mid-2030s, with fielding after the late 2030s. The government will procure the small modular reactor and main weapons directly, and domestic shipbuilders will compete for hull design and construction.
The same meeting cleared a 591bn won mine-warfare uncrewed surface vessel programme.
