North Korea Unveils First Nuclear-Powered Submarine

Seoul, South Korea

On Thursday, North Korea showcased new images of its claimed first nuclear-powered submarine, which is comparable in size to some of the U.S. Navy’s attack submarines.

The state media images featured leader Kim Jong Un inspecting the submarine at an indoor construction site, suggesting that the vessel has yet to be launched.

The ambition to build this nuclear-powered submarine has been a significant goal for Kim since he first mentioned it at a party congress in 2021. The recent decision by the Trump administration to enable South Korea to pursue similar submarines seems to have accelerated Kim’s plans.

Nuclear-powered submarines offer many advantages, including extended submerged operations that can last for years, unlike conventional submarines that require surfacing for air. They are also generally faster and quieter. Currently, only a handful of countries, including the U.S., Russia, and China, possess this technology.

The released images indicated noteworthy progress on the submarine, first announced in March, with state media reporting a displacement of 8,700 tons, rivaling the nuclear-powered Virginia-class attack submarines in the U.S. fleet.

During his inspection, Kim emphasized the vessel’s significance to North Korea’s defense strategy, stating that “the strongest offensive power” is essential for national security. He described the pursuit of this capability as vital in responding to perceived threats, particularly regarding South Korea’s nuclear ambitions, which he argued could destabilize the region.

Experts note that while Kim’s submarine project aims to strengthen military capabilities, it is North Korea itself that contributes to heightened tensions in the region by resisting diplomacy and focusing resources on military advancements instead of economic development.
