The scenario depends on governments paying for wider evasion. Its historical examples include British County-class cruisers, American Lexington conversions and submarines, Italian heavy cruisers, and French destroyers and cruisers. In the Japanese case, aggressive efforts to save weight and exploit materials are linked to ships getting into trouble in storms. Japan's subsequent move toward outright cheating follows that warning about pushing lightweight construction too far. The alternate history extends those selected practices across more of each navy's construction.
