The naval part of the counterfactual adds more ships like Błyskawica and the Grom-class destroyers. Translating a roughly 4,000-ton Oliver Hazard Perry-class frigate by displacement suggests a large destroyer or light cruiser in the earlier period. Translating by role is another possibility, so the comparison does not yield one definite fleet. A well-trained Polish County-class heavy cruiser is raised as a further hypothetical asset. Submarine numbers would fall under the comparison even though the surface fleet becomes stronger.

More Grom-class destroyers in a stronger 1939 Polish fleet
Translating modern Polish surface ships into 1939 suggests more Grom-class destroyers and possibly cruisers, while submarine numbers would fall.
