How large would the postwar navies be?

What size would each major power's navy reach after this Pacific war?

Britain and the United States could reach roughly comparable, much larger fleets, while most other powers remained limited by existing yard capacity.

The figures are deliberately approximate rather than a detailed fleet table. The Royal Navy could have between twenty and twenty-four capital ships and about eighteen aircraft carriers, with the United States at a similar scale. Germany, Italy, and France remain constrained by the shipbuilding infrastructure they already possessed, while the Netherlands might complete a battlecruiser. Japan would lose most or all of its fleet before Britain accepted peace, and even the Soviet Union might use the extra time to complete capital ships. These estimates illustrate unequal industrial elasticity and remain scenario bounds rather than firm predictions.
