If Dreadnought had used centerline triple turrets, would triples become standard?
Short answerEventually; the first successor generation would still use many twin mounts, but later battleships would likely standardize on triples.
NotesDesign practice would change in stages. Existing technical bases and conservative follow-on designs would keep twin turrets common in the first post-Dreadnought generation. Once the alternative proved workable, triple turrets would spread across later battleships. A successful lead ship can establish an architectural standard even when other navies need time to reproduce it.
