The 604th Air Support Operations Squadron is a United States Air Force unit located at Camp Humphreys, Republic of Korea. The 604th provides tactical command and control of airpower assets through the use of joint terminal attack controllers to the Joint Forces Air Component Commander and Joint Forces Land Component Commander for combat operations within the Korean peninsula.
The 604th provides joint terminal attack controllers and Air Liaison Officers to direct close air support to Army units with which they are embedded. The squadron's controllers coordinate air strikes with direct fire missions. The squadron's Air Liaison Officers advise Army commanders on the optimum use of airpower resources to support the Army.[2]
The squadron was first activated at Wheeler Air Force Base, Hawaii in September 1968 as the 604th Direct Air Support Squadron to provide Air Force personnel to man a Direct Air Support Center, an element of the Tactical Air Support System coordinating air support at the Corps level.[1] It absorbed the mission, personnel and equipment of the 7th Direct Air Support Flight, which had been performing the mission at Wheeler since October 1964 under 326th Air Division, and which was simultaneously inactivated.[3] The squadron was inactivated in May 1971.[1]
Five years later, in June 1976, the squadron was activated once again in Korea, when it replaced the 603d Direct Air Support Squadron. Squadron members were stationed in detachments at Camp Red Cloud, Camp Humphreys, and Camp Casey, South Korea, where they train to support both United States and Republic of Korea Army forces.[2] The squadron supports the United States Eighth Army. From 15 December 1994 through 13 February 1998, the terminal air controllers were organized into a separate colocated unit, the 607th Air Support Operations Center Squadron.[3] [4]
In 2018, in conjunction with the closure of Camp Red Cloud, the squadron was relocated to Camp Humphreys, where it is currently located.
