Turrets, turbines, and fire control reshape the Victorian fleet

World War I experience would make Henderson suspicious of wet casemate batteries and push him toward turreted secondary armament for cruisers and capital ships. He would not need to be persuaded that turbines offered advantages over triple-expansion machinery, so destroyers and a redesigned Canopus class could become early test beds. His memory of Jutland also favors centralized director fire control and systematic attention to armor, gun, shell, and fuze quality. The resulting ships might resemble 1920s design practice decades early, with more useful firing arcs and machinery installed around a coherent tactical system. Henderson could sell those advances as efficiency measures as well as combat improvements, making technical modernization easier to defend politically.
