North Korea possibly received nuclear reactor for submarine from Russia

South Korean military intelligence has reported that Russia may have supplied North Korea with nuclear reactor modules suitable for submarine propulsion, potentially including complete functioning reactors. These modules, possibly delivered in the first half of 2024, are believed to have been taken from decommissioned Russian submarines and include critical components such as reactors, turbines, and cooling systems. Since 2023, North Korea has reportedly been persistently requesting nuclear submarine technology and advanced fighter jets from Russia, with Moscow initially hesitant but seemingly agreeing to provide the submarine technology this year. Nuclear submarines, powered by pressurized water reactors, offer significant stealth advantages as they can operate submerged for long periods and are difficult to detect by conventional sonar or radar, though they emit a heat signature from their reactors. Possession of such technology would substantially enhance North Korea’s military capabilities, enabling covert operations in enemy territories and posing a serious threat to South Korea and potentially the United States. While North Korea may lack the indigenous capability to build nuclear submarines independently
