Only aircraft of the Royal Norwegian Navy Air Service had the range to fly all the way from their last remaining bases in Northern Norway to the UK. Included amongst the Norwegian aircraft that reached the British Isles were four German-made Heinkel He 115 seaplane bombers, six of which were bought before the war and two more were captured from the Germans during the Norwegian Campaign. One He 115 also escaped to Finland before the surrender of mainland Norway, as did three M.F. 11s; landing on Lake Salmijärvi in Petsamo. A captured Arado Ar 196 originating from the German heavy cruiser "Admiral Hipper" was also flown to Britain for testing.
