South Korea Advances Nuclear Submarine Project

On November 6, 2026, South Korea's state arms agency review committee approved the basic plan for a nuclear-powered submarine project, marking a significant step in the nation's defense strategy.

The project, known as the Jang Bogo N, aims to develop domestically built nuclear-propelled submarines, with the first expected to launch in the mid-2030s. This initiative is part of a broader agreement with the United States to bolster South Korea's naval capabilities.

The Defense Acquisition Program Administration (DAPA) announced that the project will officially commence in 2027, following an exemption from the usual preliminary feasibility study requirements. This exemption was granted to expedite the process, reflecting the urgency of enhancing South Korea's military readiness.

DAPA plans to select a manufacturer through open bidding next year, with a total budget for the project still under discussion. Reports suggest that South Korea aims to construct at least three submarines, with an estimated total cost of around 28.9 trillion won (approximately $21.3 billion).

In addition to the submarine project, the committee also approved plans for advanced missile systems and upgrades to military communication networks, further strengthening the country's defense posture against threats from North Korea.
