What was the best ship of the Second World War?
Short answerThere is no single winner; the answer changes by mission and ship type.
NotesA single best ship cannot cover the different problems solved by destroyers, carriers, support vessels, and battleships. HMS Nubian stands out among destroyers, while USS Enterprise, Ark Royal, and Illustrious form a carrier group of personal favorites. Unicorn receives separate praise as a forward aviation-support ship whose value cannot be captured by treating her as an ordinary carrier. The Iowa class leads among battleships built during the war, while older favorites remain in contention, showing why role and period must define any useful comparison.
