How an earlier 14-inch gun might reshape British dreadnoughts

What if the Royal Navy adopted 14-inch guns in place of its 13.5-inch dreadnought weapons?

The later fleet might move to 16-inch guns sooner, giving the Queen Elizabeths, Revenges, and Nelsons a more standardized armament family.

Gun calibre in this counterfactual develops as a sequence rather than an isolated substitution. If the Royal Navy adopted 14-inch weapons where it historically chose 13.5-inch, the next major jump could plausibly be to 16-inch guns for the Queen Elizabeth and Revenge classes. Germany's long run of 12-inch dreadnoughts would then face pressure to answer with a larger weapon, accelerating the international calibre race. A British fleet already standardized on 16-inch guns could push Hood and the later treaty designs toward 18-inch armament. The scenario consequently reduces the novelty of Nelson and Rodney's weapons while offering a major logistical benefit through wider ammunition standardization.
