How would the Royal Navy respond if Germany sent Bismarck and Tirpitz out together against a faster Nelson class?
Short answerBritain would likely concentrate several available capital ships against them rather than accept a two-on-two battle.
NotesBismarck and Tirpitz would not necessarily meet only two British battleships. The Royal Navy could draw from Nelson, Rodney, Hood, King George V, and Prince of Wales to assemble a stronger intercepting force. Concentrating the German ships would also concentrate British attention. Operational plans depend on the enemy force actually at sea rather than a convenient historical matchup.
