What would have happened if Germany sent its major surface ships and Graf Zeppelin to sea together?
Short answerThey would have met a much larger concentrated Home Fleet built around multiple destroyer flotillas, cruisers, capital ships, and carriers.
NotesThe proposed force combines Bismarck- and Scharnhorst-class capital ships, Admiral Hipper-class cruisers, Graf Zeppelin, and destroyers. At Scapa Flow, the Home Fleet concentration included two Tribal-class flotillas, a Town-class cruiser squadron, several capital ships, and two carriers. Further destroyers added depth to the British screen. The resulting action would have been a fleet engagement against substantial British strength rather than a one-sided German raid.
