US, South Korea agree to deepen cooperation on nuclear-powered subs, Seoul says
South Korea commits to increasing defense spending to 3.5% of GDP and integrating forces into U.S. nuclear planning to deter North Korean threats, officials said.
- On Jan. 26, 2026, U.S. Under Secretary of Defense for Policy Elbridge Colby and South Korean Defence Minister Ahn Gyu-back agreed in Seoul to deepen cooperation on Seoul's pursuit of nuclear-powered submarines, the defence ministry said.
- The NDS's call for allies to take primary responsibility prompted South Korea's pledge to raise defense spending to 3.5% of GDP and press for OPCON transfer, South Korean officials said.
- The joint fact sheet and 57th Security Consultative Meeting outcomes align critical supply chains and integrate South Korean conventional forces into U.S. nuclear planning, urging working-level talks to implement details.
- The ministry said the deal will strengthen deterrence and the alliance by boosting South Korea's military-led defense posture, though construction details remain unclear as South Korea said overseas building is 'extremely difficult' while the U.S. insisted on domestic construction.
- Colby will next travel to Japan to brief on the NDS and the Pentagon expects to release a Global Posture Review soon while officials stressed deterrence by denial along the First Island Chain.
