Royal Air Force Moreton Valence or more simply RAF Moreton Valence is a former Royal Air Force installation located 9 kilometres (5.6 mi) southwest of Gloucester, Gloucestershire and 24 kilometres (15 mi) northwest of Cirencester, Gloucestershire, England.

Peter Cadbury flew as a test pilot for Glosters during World War II, and fondly remembered his first flight in a jet, at Moreton Valence.

'Line up, set the rpm at 14,000, watch the jet pipe temperature and good luck,' he said, slapped the side of the aeroplane and walked away.

The Meteor project was Top Secret and we were told not to fly out of the Moreton Valence area and avoid having to force-land anywhere else.

"[1]In the post-war period, it was used by Glosters for further testing of the Meteor, and was also used for final completion of Javelin fighters which were built in Brockworth and flown the short distance to Moreton Valence, the runway at Brockworth being too short to safely allow a completed Javelin to take off.
