South Korea Plans First Nuclear-Powered Submarine by Mid-2030s
South Korea has announced plans to launch its first nuclear-powered submarine by the mid-2030s, a significant step in the country's efforts to modernise its naval capabilities and enhance deterrence in a volatile regional security environment. The announcement marks a major milestone in Seoul's long-term defence procurement agenda.
The programme, if successfully executed, would make South Korea one of a small number of nations operating nuclear-propelled submarine fleets, alongside the United States, Russia, China, the United Kingdom, France, and India. Nuclear-powered submarines offer far greater endurance and stealth than conventional diesel-electric vessels.
The initiative comes amid heightened security concerns on the Korean Peninsula following North Korea's repeated ballistic missile tests and continued development of its nuclear arsenal. South Korea has been progressively increasing its defence spending and pursuing advanced capabilities under successive governments.
The announcement is likely to attract close attention from regional powers, including China and Japan, and could reshape the naval balance of power in the Asia-Pacific. It also underscores the accelerating pace of military modernisation among US allies in the region.
