A successful Wilhelmshaven strike reshapes carrier doctrine

How would navies react if the planned British carrier attack on Wilhelmshaven had succeeded in 1918?

Carrier strike would become a primary interwar capability, with Britain refining it and rivals hardening their harbors against it.

A successful carrier attack on Wilhelmshaven at the end of the First World War would show that a fleet could be struck inside its harbour. Carrier-launched torpedo attack would then become a primary strategic capability in this counterfactual. Britain would invest in repeating the success, while other navies tried to protect their anchorages. Britain's frustration with the German fleet sheltering in port would thus influence interwar naval planning.
