Would an early Royal Navy triple turret lead to a Queen Elizabeth class armed with triple 13.5-inch guns?
Short answerQueen Elizabeth would likely still adopt 15-inch guns, potentially twelve of them, with the experience then shaping the Revenge and later King George V designs.
NotesQueen Elizabeth is expected to retain the 15-inch calibre, perhaps with twelve guns instead of eight, because the class was meant to advance beyond the preceding generation. A conventional four-triple Queen Elizabeth could in turn make a similar battery attractive for the slower Revenge class. Decades of operating triples would also change the later choice between quadruple mounts and triple 16-inch guns for the King George V generation. The counterfactual therefore affects later turret policy as well as the immediate battery choice.
