If Hood had been rebuilt on the model of Renown before the war, would she have survived Bismarck?
Short answerProbably; a full reconstruction would materially improve her survivability, though it could not guarantee the outcome of a battle governed by chance hits.
NotesA Renown-style reconstruction completed before the war would probably improve Hood's chance of surviving Bismarck. Hood had already received several interwar refits and was not unchanged from her original completion. A full reconstruction would go much further by revising protection, machinery, and internal arrangements together. The conclusion remains probabilistic because the historical loss depended on an exceptionally damaging hit.
