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.
