If Canada produced a naval two-seat Spitfire in 1939, what changes and how would the RAF react?
Short answerThe RAF likely leaves it to the Navy, while the Fleet Air Arm gains a faster Fulmar replacement and might use carriers to ferry aircraft from Canada.
NotesThe RAF would probably leave a naval two-seat Spitfire variant to the Fleet Air Arm, while the Navy would welcome a faster fighter. Courageous and Ark Royal might also have been more useful ferrying full carrier loads from Canada than conducting early anti-submarine patrols.
