A 15-inch Yukon design changes new battleships and older refits

How would World War II change if Yukon-class battleships and their sisters had been built in the 1930s?

Triple turrets could bring the new battleships into service sooner, while the proposed 15-inch/45 gun could improve the range and accuracy of older capital ships.

The hypothetical Yukon design puts nine 15-inch guns in triple turrets on a King George V-type battleship. Those mountings are judged easier to organize than the historical quadruple turrets, offering earlier service and fewer turret problems. The proposed 15-inch/45 gun is also described as lighter than the older 15-inch/42, allowing it to be fitted to existing British dreadnoughts. Its extra range and accuracy could improve the fighting power of Renown, the Queen Elizabeths and the Revenge class. More hits against Scharnhorst or Gneisenau could keep a German capital ship out of action for much longer. The potential change to the war accumulates through several such engagements and reduced demands on British forces.
