RAF Cowden was a Royal Air Force bombing range, near to the village of Aldbrough, East Riding of Yorkshire, England. The site was used by the RAF and other air forces between 1959 and 1998, though the land part of the site was used by the army for training in the Second World War. Since closure, explosive ordnance disposal (EOD) teams have had to visit the site on numerous occasions due to erosion of the cliffs by the North Sea revealing old practise bombs.
