How long could Bismarck last if USS Texas caught her?
Short answerPossibly hours, but any damage could leave Bismarck unable to escape the pursuing Royal Navy.
NotesBismarck's best option against USS Texas would be to avoid combat and preserve enough speed to escape. If Texas forced a gunfight, Bismarck might survive for hours, but even limited damage would threaten her larger mission. A damaged German battleship still had to cross the Atlantic while the Royal Navy closed in. The counterfactual therefore turns on escape and cumulative pursuit rather than a simple duel to the sinking.
