Korea, US kick off combined air drills this week

Freedom Flag is a combined air exercise involving South Korea and the United States. It trains the allies to plan and conduct wartime missions together. The exercise focuses on counter-air and air interdiction, while also improving procedures for joint operations. Its importance extends beyond flying practice because it tests how effectively the two countries can operate as one force.

This year's drill began Monday at Kunsan Air Base in Gunsan. The base is about 180 kilometers southwest of Seoul. The exercise will continue for two weeks. South Korean F-15K, KF-16 and F-35A fighters are participating, along with support aircraft such as the KC-330 and E-737 Peace Eye.

Freedom Flag was launched in 2024 as a semiannual exercise. It replaced Korea Flying Training in the first half of the year and Vigilant Defense in the second half. This iteration also evaluates Korea-led combined exercise planning as Seoul works toward retaking wartime operational control by 2030 or earlier.

Freedom Flag is broad in both scale and mission variety. It combines aircraft from South Korea's Air Force with assets from the U.S. Air Force, Navy and Marine Corps. That mix lets the allies practice more than fighter combat. They can also rehearse transport, reconnaissance, airborne command and control, helicopter operations and unmanned surveillance.

South Korea is deploying F-15K, KF-16 and F-35A fighter jets. Its KC-330 transport aircraft and E-737 Peace Eye early warning and control aircraft will also participate. The United States is sending Air Force F-16 and RC-135 aircraft, a Navy MH-60S Seahawk helicopter, and Marine Corps F-35B fighters and MQ-9 Reaper unmanned surveillance aircraft.

The varied fleet supports the exercise's counter-air and air interdiction missions. It also gives the allies a practical setting for exchanging tactics and refining procedures across different aircraft types. The exercise therefore tests how separate national capabilities work together during combined operations.

Counter-air missions are wartime actions intended to gain and protect control of the air. They can include defending friendly aircraft and forces, detecting threats, and engaging enemy aircraft or airborne systems. Air interdiction missions strike enemy forces, supplies or movement routes before they can reach and support the main fight. Together, these missions reduce threats and limit an opponent's ability to operate.

At Freedom Flag, the allies are practicing these mission categories through combined planning and execution. South Korean and U.S. aircraft will use mission planning cells to exchange tactics and expertise. The exercise includes fighters, reconnaissance aircraft, early-warning aircraft, helicopters and unmanned surveillance aircraft. These assets provide different capabilities for finding, protecting against and disrupting threats.

The stated goal is to enhance interoperability and build combined operational capabilities. The drills also refine wartime procedures. That matters because successful missions depend not only on aircraft performance, but also on coordinated decisions, shared information and clear execution between the two forces.

Mission planning cells are working groups where military personnel prepare operations, coordinate resources and turn objectives into executable plans. Running them during both day and night exposes the allies to different conditions and schedules. It also creates a continuous setting for comparing methods, identifying gaps and practicing decisions under realistic pressure.

During Freedom Flag, South Korean and U.S. air forces will exchange tactics and expertise in these cells. They will also refine wartime operational and mission execution procedures. The planning work connects the exercise's varied aircraft, including fighters, reconnaissance platforms, helicopters, transport aircraft, early-warning systems and unmanned surveillance aircraft.

The result should be better coordination before aircraft launch and during missions. Personnel can develop a shared understanding of roles, timing and procedures. The article presents this as a way to enhance interoperability and build combined operational capabilities. It also supports testing Korea-led planning as Seoul works toward regaining wartime operational control.

Wartime operational control, or OPCON, is the authority to direct military operations during wartime. In the South Korean-U.S. alliance, the article says Seoul is working to retake this control from Washington. Regaining it would place South Korea in the lead for directing the combined forces during wartime operations, while the allies would still operate together.

Freedom Flag helps test that transition. The exercise will evaluate the planning and execution of Korea-led combined drills. South Korean and U.S. personnel will work through day and nighttime mission planning cells, exchange expertise and refine operational procedures. Those activities give Seoul opportunities to demonstrate leadership in a demanding combined setting.

South Korea seeks to retake wartime OPCON by 2030 or earlier. The article links that goal to verifying South Korea's capabilities to lead the combined forces. Freedom Flag therefore serves both as a readiness exercise and as an evaluation of Korea-led planning, coordination and mission execution.

Before leading the combined South Korean-U.S. forces, South Korea must verify that it can direct major wartime operations. The article specifically connects this requirement to capabilities for leading the combined forces. That includes more than owning advanced aircraft. It involves organizing plans, coordinating allied assets, making operational decisions and executing missions effectively.

Freedom Flag provides a practical test. The drills will evaluate the planning and execution of Korea-led combined exercises. South Korean and U.S. air forces will operate mission planning cells during the day and night. They will exchange tactics and expertise while refining wartime operational and mission execution procedures. The exercise also practices counter-air and air interdiction missions.

These activities let South Korea demonstrate leadership within a real combined framework. They can reveal whether procedures, personnel and aircraft work together effectively. Seoul seeks to retake wartime operational control by 2030 or earlier, but the article does not provide a detailed checklist or final assessment of each capability.

Military interoperability is the ability of different forces to work together effectively. It includes sharing information, understanding procedures, coordinating decisions and using different aircraft and units in a connected operation. For South Korea and the United States, interoperability is essential because their wartime missions depend on combined forces rather than isolated national actions.

Freedom Flag builds this ability through day and nighttime mission planning cells. Personnel exchange tactics and expertise while refining wartime operational and mission execution procedures. The exercise brings together South Korean fighters, transport and early-warning aircraft with U.S. fighters, reconnaissance aircraft, a helicopter and unmanned surveillance systems. Those varied assets must support the same operational goals.

The article says the missions are designed to enhance interoperability and build combined operational capabilities. Better interoperability can make planning clearer and execution more coordinated. It also supports Korea-led combined exercises, which are part of South Korea's effort to verify its ability to lead the forces and retake wartime OPCON.
