U.S. Marine drone flew near South Korea border without approval

July 31 (Asia Today) — A U.S. Marine Corps drone that triggered an unidentified aircraft alert near South Korea’s border Thursday flew before receiving final advance approval from the South Korean military, according to military officials.

Authorities are investigating whether the lapse resulted from an incomplete coordination request by the U.S. military or a breakdown in communication within the South Korean chain of command.

Residents south of the Civilian Control Line in northern Gyeonggi Province received emergency evacuation messages after the aircraft was detected at about 2:30 p.m.

South Korea’s Joint Chiefs of Staff said at 3:30 p.m. that an unidentified aircraft had been detected south of the General Outpost line and that military units responded under standard operational procedures.

The aircraft was later identified as a U.S. military drone participating in a training exercise, and the situation ended without shots being fired, the Joint Chiefs said.

A Joint Chiefs official said the drone did not cross north of the General Outpost line. The military is analyzing its flight path to determine whether it entered restricted airspace near the Military Demarcation Line.

U.S. Forces Korea said the aircraft was a Marine Corps drone used during combined training involving South Korean and U.S. Marines.

The drone was operated during a Korea Marine Exercise Program drill near the Rodriguez Live Fire Range Complex in Pocheon, Gyeonggi Province. The training area is commonly known in South Korea as Story Range.

U.S. Forces Korea said it was coordinating with the South Korean Marine Corps and other authorities but did not confirm whether the required advance notice had been completed.

South Korean and U.S. military officials said the drone began flying before final authorization was issued through the appropriate South Korean operational command.

Even if the U.S. military had contacted a local South Korean unit, the flight proceeded before the approval process was completed.

Information about the flight also was not shared in real time with frontline surveillance units or the Joint Chiefs’ operational command.

The communication failure created a risk that South Korean forces could mistake the aircraft for a North Korean drone and respond with gunfire or other military action.

The Joint Chiefs said investigators were examining whether the U.S. military failed to submit a complete coordination request or whether South Korean units failed to properly report and distribute the flight information.

A former senior South Korean military official who served with the Army’s I Corps and the Joint Chiefs said the incident exposed a serious weakness in frontline readiness.

The official, who requested anonymity, said communication appeared to have broken down among I Corps, the South Korean Marine Corps Command and the Joint Chiefs despite the flight being part of a combined exercise.

The incident should not be dismissed as a minor misunderstanding, the former official said.

Military officials said a broader inspection may be necessary to determine where the notification and approval process failed and whether disciplinary action is warranted.

Frontline unit received no advance notice

The combined Marine exercise was conducted near Story Range in Pocheon, an area where the South Korean Army’s I Corps coordinates military activity.

South Korean Marines, including personnel from the 1st Marine Division, reportedly participated in or supported the training alongside U.S. forces.

The frontline General Outpost unit, however, apparently received no advance information about the U.S. drone flight.

The unit detected the aircraft through thermal observation equipment and began an emergency response because it could not rule out a possible North Korean drone intrusion.

A Joint Chiefs official said personnel at the scene confirmed the aircraft belonged to the U.S. military but that its exact route required further analysis.

Investigators will examine why the flight information was not transmitted through the South Korean military and where communication among the responsible commands broke down.

Authorities also are reviewing why emergency evacuation messages were sent to residents south of the Civilian Control Line and whether the alerts were issued appropriately.

The military is conducting a detailed flight-path analysis to determine whether the drone entered a no-fly zone established near the Military Demarcation Line.

Officials also are reviewing whether the flight entered an area where drone operations had been restricted under the 2018 inter-Korean military agreement.

Military experts said effective combined defense depends not only on major exercises and strategic planning but also on the real-time exchange of operational information, including the route of a single tactical drone.
