Yamato and Bismarck are used to compare the strongest individual ship with the strongest fleet a navy can field. Britain and America needed numbers and expected to use several ships against a powerful opponent. The example envisages three or four modern battleships concentrating their fire against one larger ship. That changes the design comparison from a duel between individual hulls to the firepower available in a fleet engagement.

Treaty compliance pushed Britain and the United States toward effective fleets rather than a few individually dominant battleships.
