Wroughton was home to RAF 15 MU (a storage unit) between Apr 1940 and Mar 1972. It has not been an active flying base for a great many years. Since at least the mid 1970s, its main role has been as a short and long term storage facility, principally for the Fleet Air Arm through the Royal Naval Aircraft Yard (RNAY) and also for other branches of the Ministry of Defence, as well as organisations, such as the Science Museum and the Fleet Air Arm Museum.
The RNAY finally closed on 3 Sep 1992 and many (but not all) of the airframes were dispersed. Some of the storage facilities remain.
