No. 11/18 Group was a short-lived formation of Strike Command in the Royal Air Force. It was formed in 1996 as part of the post-Cold War reorganisation of the RAF. It absorbed the forces of No. 11 and No. 18 Groups, which were descended from the old Fighter Command and Coastal Command functional commands. It only lasted until 2000, when a further reorganisation of Strike Command saw its assets transferred to No. 1 and No. 3 Groups. The headquarters appears to have been based at RAF Bentley Priory, the last use of the underground command facilities there, as the successor groups were moved to RAF High Wycombe.
