Charlotte,
Our Vampire was a static gate guard. It had no guns or even an engine fitted. It just sat outside the squadron hut and was used to back up various classroom training on airframes, principles of flight etc.
I was on 221 (Great Yarmouth0 Squadron ATC from 1965 to 1972, after which I left for a while to start work. I went back as an instructor in 1976. When I did, the jet had been scrapped, and all the squadron had were a few instruments and the two de-activated ejection seats. Eventually the instruments went as well, as a safety inspection found they were radium painted and deemed a health hazard.
For the record our jet was XD511, and was in RAF Cranwell markings.
Hope this helps
Regards
B
