Why is Hood usually described by her 41,200-ton displacement rather than the Admiral-class design figure of about 36,500 tons?
Short answerBecause the 41,200-ton figure describes the ship as built, while the smaller number belongs to an earlier design state.
NotesThe question contrasts the Admiral-class design figure of roughly 36,500 tons with Hood's completed displacement of about 41,200 tons. Most discussions use the built version because that is the ship that actually existed. A paper design and the completed vessel are therefore different reference points even when they share a class lineage. Design-stage and as-built figures need clear labels rather than treatment as interchangeable specifications.
