Could Renown have hunted Bismarck instead and freed Hood for refit?
Short answerNot simply; Renown had other operational commitments, and the Bismarck hunt did not occur in isolation.
NotesA viewer asks whether Renown could have taken Hood's place in the Bismarck hunt and thereby freed Hood for refit. Renown was already carrying out other tasks. Bismarck's sortie mattered, but other ships and operations continued at the same time. Fleet availability must therefore be judged across simultaneous commitments rather than by swapping two famous ships inside a single isolated episode.
