Pilatus tested their new PC-24 recently on former RAF Woodbridge ( USAF 81st TFW and 39th SOW until 1993) now Rock Barracks runway.
Recently Rock Barracks / Woodbridge runway is being used for testing of Pilatus PC-24
I believe using the rough runway is in certifying the a/c for their first customer Royal Flying Doctor Service.

Also the Airbus A400M has been flown in and out and even the Volga Dnepr IL-76 ( think it was filming for latest Jurassic)
