The first predecessor of the unit was the 15th Radio Squadron, which was activated in 1951 and performed signals intelligence missions from locations in Japan and Korea during the Korean War. It was inactivated in May 1955 and its mission and assets were transferred to the 6922d Radio Group, Mobile.
The 315th's second predecessor was the 6922d Security Group, which was activated at Clark Air Base in the Philippines in April 1970. When the American presence in Southeast Asia was reduced, the group was reduced in size and became the 6922d Security Squadron. This unit was inactivated with the closure of Clark due to the eruption of Mount Pinatubo in 1991. These two units were consolidated as the 315th Intelligence Squadron in 1993.
The 15th Radio Squadron, Mobile was organized at Brooks Air Force Base, Texas for service in the Korean War. In July, the squadron departed Texas for Ashiya Air Base, Japan, where it was to operate until inactivated in May 1955.[3] Upon the squadron's arrival in Japan, the former Detachment 3 of the 1st Radio Squadron, Mobile, located at Ewha Womans University in Seoul, Korea was transferred to the 15th as Detachment 1, 15th Radio Squadron, Mobile. The squadron mission was to provide tactical intelligence data to the air operations center of Fifth Air Force in Korea, located a short distance from Detachment 3.[4]
In May 1955, the squadron was inactivated and its mission, personnel and equipment were transferred to the 6922d Radio Group, Mobile at Ashiya.[2] It was kept on the Air Force's books as an inactive unit until June 1983, when it was disbanded.[3]
Clark Air Base
The 6922d Security Group was activated in April 1970 at Clark Air Base in the Philippines.[3] Initially, the group conducted operations through subordinate detachments ranging from Thailand through Japan. With the withdrawal of the United States from Vietnam, operations were substantially reduced, and by 1974 were limited to direction finding, and the group was reduced to the 6922d Security Squadron. Operations continued through June 1991, when Mount Pinatubo erupted, covering Clark with volcanic ash. It became apparent that resumption of operations at Clark was neither financially or politically viable, and the squadron began to devote itself to the salvage and removal of equipment, except for a small contingent of linguists. The squadron was inactivated as remaining Air Force assets at Clark were turned over to the Philippine government.[3][2]
Consolidated unit
The 15th and 6922d squadrons were consolidated in 1993 as the 315th Intelligence Squadron at Yokota Air Base, Japan. The squadron was inactivated in 2001, but was again activated as the 315th Information Operations Squadron at Fort George G. Meade, Maryland, where it has been active under various designations until today.[3]
