The other Nelson/Rodney BB class that could of have-been. Although UK RN could break the Washington treaty build those for 5 and have the rest of the new BBs done as King George V classes. But it's just a whimsy.
Just be glad, the Italians and the Allies didn't get a nasty encounter of a flotilla of these KuK BCs during the Dardanelles campaign or later on in the war.
