Interwar austerity delayed British large-cruiser construction capacity

Could Britain have built a 25,000-ton, 12-inch-gun large cruiser before the Second World War?

Yes, if the government had funded rearmament earlier; available yards could support more construction, but policy delays and even the dismantling of heavy cranes worked against rapid expansion.

Britain retained yards that could build more warships if money arrived soon enough. Although the Ten Year Rule formally ended in 1932, policy did not fully behave as though it had ended until about 1937. That delay constrained how quickly projects such as a 25,000-ton large cruiser could move from possibility to construction. Heavy cranes dismantled in the late 1930s and later rebuilt show how peacetime economy could erase capacity just before it was needed again.
