Could the King George V design have carried additional quadruple turrets by narrowing barbettes and shifting armor weight?
Short answerProbably not in the conventional layout, though a purpose-designed all-forward ship might achieve twelve guns on 35,000 tons.
NotesNarrower barbettes or reductions in deck protection would not automatically recover enough weight and volume for another historical-style quadruple mounting. Three all-forward quadruple turrets or another twelve-gun arrangement appear more plausible if the entire ship were designed around it from the start.
