South Korea and US Differ on Wartime Operational Control, Nuclear Subs

South Korean Defense Minister Ahn Kyu-back met with U.S. Secretary of Defense Hegseth in Washington to discuss the transfer of wartime operational control.

The meeting highlights a critical tension in the security alliance as Seoul seeks greater military autonomy to counter regional threats. South Korea is pushing for an earlier transfer of operational control and the acquisition of nuclear-powered submarines to strengthen its independent defense posture [1, 2].

Ahn said the transition of wartime operational control should occur by the first quarter of 2029 ^[2]. This move would shift the authority to direct military operations during a conflict from the U.S.-led Combined Forces Command to South Korean leadership.

However, the discussions revealed a significant gap in perspectives between the two nations [1, 2]. While Seoul views these steps as essential for self-reliant defense, U.S. officials said that other global priorities, including conflicts involving Iran, currently take precedence ^[2].

The request for nuclear-powered submarines is another point of contention. Such vessels would provide South Korea with enhanced stealth and endurance, but the acquisition of nuclear propulsion technology is subject to strict international non-proliferation standards and U.S. oversight ^[1].

Neither side has reached a formal agreement on the 2029 timeline or the submarine procurement. The meeting concluded with both parties acknowledging the differing priorities of their respective defense establishments ^[2].
