Could the Polish submarine Orzel have sunk Bismarck in the Kattegat?
Short answerHer torpedoes could have sunk Bismarck, but the ships' timelines make an encounter unlikely because Orzel was lost before Bismarck completed commissioning and trials.
NotesThe magnetic-pistol problem that afflicted early American torpedoes is not the decisive issue. Orzel's June 1940 loss and Bismarck's later commissioning and trials leave little realistic overlap in the Kattegat.
