North Korea makes progress on its first nuclear-powered submarine | Euronews
North Korea is showing measurable progress toward building its first nuclear-powered submarine, according to recent assessments based on satellite imagery and expert analysis. The images indicate construction activity at key shipyard facilities, suggesting preparation for integrating a nuclear reactor section into a submarine hull. If completed, such a vessel would significantly expand Pyongyang’s naval reach, allowing longer underwater endurance and greater strategic deterrence compared to diesel-powered submarines. Analysts caution that development remains complex and time-consuming, with major technical hurdles still to overcome, particularly reactor safety, crew training, and quiet operation. The project also raises fresh security concerns for South Korea, Japan, and the United States, as a nuclear-powered submarine could enhance North Korea’s second-strike capability. While timelines remain uncertain, the apparent progress underscores Pyongyang’s continued focus on advancing its military technology despite international sanctions and diplomatic pressure.
