315th Cyberspace Operations Squadron

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]

By 1952, the need for intelligence collection closer to the battle lines than Seoul became evident. The People's Liberation Army Air Force was upgrading their tactical communications from High Frequency to Very High Frequency systems, which could not be effectively detected at long ranges.[5] Fifth Air Force began to operate Douglas C-47 Skytrain aircraft from Yokota Air Base, Japan. Members of the 15th flew in the back of these airplanes, which patrolled just behind the front lines and off the coast of North Korea, recording data on wire recorders. Recordings were dropped to the unit's Detachment 2, which had been established on Cho Do Island, off the coast of North Korea.[4] This was then transferred to ground controlled intercept controllers of the 608th Aircraft Control and Warning Squadron on the island to provide near real time threat information to American fighter aircraft.[5]

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]

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]

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]
