HMS Iron Duke would rank close to the top on her own merits. She served as Admiral Jellicoe's flagship and was an important Royal Navy capital ship during the First World War. Her disadvantage in this personal comparison is the narrower span of her service story: Iron Duke represents one world war, while Warspite made major contributions in two. The contrast shows why operational longevity, as well as design quality and fleet leadership, shapes the final choice.

Why Warspite ranks ahead of Iron Duke
Iron Duke receives an honourable mention as Jellicoe's flagship and a crucial First World War battleship, but Warspite's two-war career wins the comparison.
