The Squadron was formed at Reykjavik, Iceland on 25 April 1941 from Norwegian personnel, who had managed to escape from Norway and then undergone training in Canada. They initially flew with RAF Sunderland crews but in May aircraft ordered by the Norwegian government arrived in the form of Northrop N-3PB seaplanes. The Squadron was attached to Coastal Command and operated from bases in Iceland and Scotland.
