What if these ships were never built? As much of a prestige boost these ships were, they were nothing really that special in comparison with their competition and basically sunk for a fraction of their cost.
So, if the Germans do not build these ships, but maintain the rest of their ships what resources are made available? I know that not building them does not free up factories for making more AFV or planes, but it does free up the money and resources used to make the ships.
This would also mean that Plan Z is not implemented, as it would be foolish to compete with the Brits who would be able to outproduce any nation, expect for the US, in ship building.
So, do the resources go towards Uboats? This would alarm the Brits more than the Battleships would and be viewed as a direct threat to the Allies. Also they would take steps to counter this build up by building more destroyers. However, this would help create the infrastructure for more Uboats in the most vital period of the battle of the atlantic.
How does it change the war?
