Good analysis. +1 to you.
Had the Germans had these, though, it would be hard to say what they would match up against. Britain and France would have ships to counter these. Instead of being an answer to the Deutschland class, they would have had to have built answers to the more powerful Mackensens. The KGV very likely would have had 15 guns rather than 14s.Â
Very hard to figure out what France and Britain would have responded with. And in turn, whatever the French did would influence the Italians. My guess is you would have seen a much more aggressive battleship race between the major powers. The super battleships planed by everyone probably would have materialized sooner.
Well said.
