(AACS). As part of the establishment of the Air Force Communication Service as a separate major command, Air Force Communications Command, in 1961, the 1230 AACS redesignated to become the 2130th Communications Squadron (CS). In just over ten years the mission and unit grew to the point that it needed to redesignate to the 2130th Communications Group (CG). By 1977, the 2130 CG controlled USAF communication resources from as far south as Cornwall, England and as far north as Keflavík, Iceland. With the formation of the 2147th Communications Group at RAF Mildenhall and the realignment of many squadrons, detachments, and Operating Locations in 1980, the 2130 CG inactivated. Several communications missions at RAF Croughton, like the Defense Communications System, and Global Command and Control Radio System, combined with the responsibility for their maintenance falling on the 2168th Communications Squadron at RAF Upper Heyford. This changed again with the reactivation of the 2130th Communications Squadron on 1 July 1983 to manage the communications missions at RAF Croughton. The mission increased in December 1985 when the Giant Talk station at RAF Croughton began operations. In 1988 the 2130 CS again redesignated to become the 2130th Communications Group. The beginning of 1993 saw several big changes for RAF Croughton. Most of these had to do with mission support. With the projected inactivation of the 20th Fighter Wing at RAF Upper Heyford and closure of that station the 2130 CG redesignated to the 630th Communications Squadron. This new squadron functionally aligned under the 100th Communications Group (CG) at RAF Mildenhall. However, this was no ordinary communications squadron. Before the closure of RAF Upper Heyford, RAF Croughton had relied on the larger base for administrative support to one degree or another. The closure of RAF Upper Heyford forced the squadron to look for ways to be as self-sufficient as possible. To handle most day-to-day support functions, the squadron had its own finance, personnel, supply, and other support elements. It became a mini-station. During this time RAF Croughton received most of its mission support from the 100 CG as well as some from the 100th Regional Support Group (RSG). Both of these units resided at RAF Mildenhall under the 100th Air Refueling Wing (ARW). This changed on 1 July 1994 when United States Air Forces in Europe (USAFE) conducted another command-wide reorganization. One result of this reorganization was the inactivation of the 100 RSG, its subordinate
