How would earlier successful heavy-gun development affect HMS Dreadnought?
Short answerDreadnought might begin with much heavier guns, immediately forcing rival all-big-gun ships to standardize at the new calibre.
NotesVickers was already pushing practical larger-gun designs when Dreadnought was conceived. A mature history of 16-inch manufacture would make that calibre a possible starting point rather than a later escalation. Rivals would then standardize their own all-big-gun ships around the heavier weapon. Dreadnought's revolutionary effect depended on both layout and the contemporary armament baseline.
