Focus on OPCON Transition Within Lee Jaemyung's Term... Required Conditions

Commander Brunson: "Transition by Second Quarter of 2029"
Trump Administration's Commitment Crucial as Timeline Aligns with U.S. Presidential Election

Javier Brunson, Commander of the United States Forces Korea and United Nations Command, stated on April 22 (local time) regarding the transition of wartime operational control (OPCON), "We have submitted a roadmap to the Department of Defense to achieve the relevant conditions by the second quarter of Fiscal Year 2029 (which corresponds to the first quarter of 2029 in Korea)." This period refers to January to March 2029 in South Korea, falling within the term of President Lee Jaemyung.

Although Commander Brunson has officially disclosed the timing for the OPCON transition, the political timeline could become an obstacle. The period he mentioned—before the second quarter of Fiscal Year 2029—coincides with the timing of a U.S. administration change. A crucial factor will be how actively the Trump Administration pursues the OPCON transition during its term, which ends on January 20, 2029. If the Trump Administration does not accelerate the transition process, the final decision will fall to the next U.S. president. Depending on the outcome of the U.S. presidential election in November 2028 and any shifts in the security policy direction of the subsequent administration, the OPCON transition schedule may inevitably be delayed further.

Meeting the conditions for the OPCON transition is also essential. Commander Brunson reiterated at the Senate Armed Services Committee the previous day, "Political expediency must not override the required conditions" regarding the authority over OPCON. This reaffirms the principle that the decision should be based on South Korea's military readiness and the fulfillment of required conditions.

The evaluation and verification for the OPCON transition proceed in three stages: Initial Operational Capability (IOC), Full Operational Capability (FOC), and Full Mission Capability (FMC). The FOC evaluation has already been completed, and the verification process is currently underway.

There are concerns in some quarters that meeting the conditions for the OPCON transition may be realistically difficult. Currently, the Multiple Launch Rocket Systems (MLRS) held by the United States Forces Korea need to be replaced with Cheonmu guided missiles, and the Army Tactical Missile System (ATACMS) with Hyunmoo-II missiles. However, South Korea currently possesses only 73% of the required Cheonmu guided missiles, 74% of the required FA SCAM (mine-scattering munitions), and 81% of the required 155mm high-explosive shells.

There is a high possibility that at the 58th ROK-U.S. Security Consultative Meeting (SCM), scheduled to be held in Washington, D.C. this October, both South Korea and the United States will present a joint target year for the OPCON transition. While some sources have suggested that 2028 would likely be proposed as the target year, with Commander Brunson specifying "by the first quarter of 2029" as the goal for fulfilling the conditions, coordination of the exact timing is expected to become a key issue in future discussions.
