Last time I looked it was used as a training area for Apaches and others from Wattisham, who would use a low-level corridor to the Woodbridge/Bentwaters training area and back for noise reasons.
The local and precious second-homers from London objected 10 years ago, with much middle-class wailing, outright lying and gnashing of teeth to the re-opening of Bentwaters as a largely maintenance base and employment locus with a few, very few schedule flights.
It was and remains one of life's sweetest ironies that the consequent refusal of consent for Bentwaters allowed the whole area of the two runways to be taken over for high intensity training by some of the noisiest aircraft around.
But I haven't been there for some years and perhaps that's all changed.
