During its time in Scotland, it was to sort out the final problems with the Rolls-Royce Peregrine engines and Hispano cannon. To fill the gap the squadron was provided with Hawker Hurricanes which were flown in action a few times. Production of the Peregrine by Rolls-Royce was slow and it was November before the squadron was fully equipped. The squadron transferred to RAF Exeter, commencing Chameleon patrols against enemy E-boats stationed in the English Channel and Western Approaches which would rescue bomber crews who had "ditched" in the sea. Here, on 12 January 1941, a section patrolling near the Isles of Scilly located a Junkers Ju 88 and Pilot Officer (PO) Stein was credited with a probable kill.
