A new enemy could preserve Britain’s battleship construction

The historical wartime program did not proceed as if Britain needed a second capital-ship fleet for North America and the Pacific. In this counterfactual, the Admiralty would accelerate construction and reconsider the decisions that produced Renown and Repulse from the wider R-class program. Britain would still need enough modern ships to contain Germany, but it would also want heavier units able to support mobile battlecruisers off the American coast. A Queen Elizabeth-class battleship and several R-class ships could eventually reinforce that theatre while Japan applied pressure in the Pacific. This scenario-dependent shipbuilding response shows how the identity and geography of an enemy alter procurement choices before a battle is fought.
