A German carrier changes how Britain risks its own

Courageous and Ark Royal could conduct exposed anti-submarine patrols historically because Britain did not expect an enemy carrier strike. A visible German carrier removes that assumption and encourages the Royal Navy to follow its own more protective operating models. Accelerated construction and the likely survival of Courageous give Britain enough ships to organize several two-carrier groups rather than scatter individual decks. Each pair can operate with fast capital ships, while another group maneuvers to reinforce it if Germany concentrates. The change makes Courageous and Glorious more likely to survive and gives Britain a much stronger carrier concentration for the Norwegian campaign.
