It was inevitable that certain areas of Wales would be chosen as locations for airfields in times of conflict & war. The nations distance from Continental Europe made it relatively safe from enemy attack & therefore ideally suited for training. It also due to its location on the western side of Great Britain near to the Western Approaches & the Atlantic convoys that the airfields in Pembrokeshire as a peninsula were ideally suited for Coastal Command operations into the Atlantic & the Bay of Biscay. In Wales there were thirty-seven airfields & four relief landing grounds eleven of which were operationally involved in air defence & maritime operations. Also there were numerous temporary landing areas attached to army camps associated with pre D-Day landings which do not count as proper airfields.
