How a giant Spanish fleet would alter the naval balance in 1940

How would Britain, France, and the other naval powers react if Spain suddenly possessed four battleships, thirty-one cruisers, and 210 destroyers in January 1940?

Britain and France would treat Spain as a major threat, accelerate or preserve their own construction, and might consider a preemptive strike, while Spain would struggle to crew so many ships after its civil war.

The panel stresses that 210 destroyers alone would create a strategic problem regardless of their individual quality. Britain and France would likely keep building ships already on the stocks rather than pause their programs, because Spain would suddenly rival major fleets in several categories. The discussion even raises preemptive attack or a cutting-out operation as possible responses to such a concentrated threat. Spain's weakness would be personnel: the recent civil war had divided its navy, so finding trained crews for the enlarged force would take time. Fleet strength on paper still depends on mobilization, trained personnel, and the reactions it provokes in other powers.
