British planners ranked Japan first, Italy second, and Germany third among naval threats. Japan possessed the world's second-largest treaty navy and lay on the far side of Britain's support network, while Italy had six battleships built or building. German declarations and Plan Z were less immediate because the fleet and submarine arm were still small and much of the proposed construction existed only on paper. The subdivision and design of the Scharnhorst class support classifying its ships as fast battleships, while their eleven-inch guns reflected what Germany could produce. The Versailles settlement had deliberately forced German maritime industry to restart from a low base, limiting how quickly it could expand or replace losses.
