Could Germany use an aircraft carrier to attack Harland and Wolff?
Short answerTheoretically, but its likely route around Scotland would expose Germany's scarce carrier to Royal Navy submarines.
NotesA carrier raid is a theoretical alternative to sending land-based bombers to Belfast. Committing Germany's sole carrier would put a scarce ship at considerable risk. A route via Norway and around northern Scotland would probably cross waters used by Royal Navy submarines for training. The carrier might therefore be intercepted before it could approach Harland and Wolff.
