U.S. Air Force Activates 431st Squadron, Establishing Permanent MQ-9 Reaper Unit in South Korea

The Kunsan-based drones expand ISR coverage across the Indo-Pacific to bolster joint responsiveness.

Overview

  • The 7th Air Force formally activated the 431st Expeditionary Reconnaissance Squadron on Sept. 29 at Kunsan Air Base.
  • Lt. Col. Douglas J. Slater assumed command of the unit, which consolidates prior rotational MQ-9 operations.
  • Officials said the MQ-9s will support U.S.–ROK priorities across the theater, enhancing deterrence and crisis response.
  • The activation revives a World War II-era 431st squadron designation, though the Air Force withheld aircraft and personnel numbers for operational security.
  • Reapers recently trained in South Korea during Freedom Flag and conducted an inert JDAM drop at Jikdo Island, underscoring surveillance and strike-capable roles.
