No. 228 Squadron RAF was a squadron of the Royal Air Force active at various times between 1918 and 1964. It spent the greatest part of its existence flying over water, doing so in the First, and Second World Wars and beyond, performing anti-submarine, reconnaissance and air-sea rescue tasks.

Royal Air Force St. Eval or RAF St. Eval was a Royal Air Force station for the RAF Coastal Command, southwest of Padstow in Cornwall, England, UK. St Eval's primary role was to provide anti-submarine and anti-shipping patrols off the south west coast. Aircraft from the airfield were also used for photographic reconnaissance missions, meteorological flights, convoy patrols, air-sea rescue missions and protection of the airfield from the Luftwaffe.
