What could be changed in the original Dreadnought design, and how would that affect the naval arms race?
Short answerA 24-knot ship with 14-inch guns was plausible and would pressure Germany while forcing later battlecruisers to become faster.
NotesForeknowledge could plausibly secure 14-inch guns and a speed of 24 knots, even if removing the wing turrets remained difficult. That larger benchmark would worsen Germany's Kiel Canal and ship-size dilemma. It would also erase the historical speed margin of the first battlecruisers, forcing their successors toward about 28 knots to preserve a distinct role. The counterfactual therefore accelerates both capital-ship size and speed competition.
