RAF Carlisle was just one in a chain of several Maintenance Units forming RAF Support Command, later to become RAF Logistics Command in 1994. Logistics Command was faced with a contracting air force that had fewer airfields, fewer aircraft, and fewer personnel. The logical answer was a reduction in the number of maintenance units. 14 MU was the farthest flung location in the UK, now isolated with most northern RAF stations already closed. RAF Carlisle would prove to be an early target for closure in the Strategic Defence Review (SDR) which marked the beginning of a modernisation that moved towards a unified tri-service logistics support.
