If Britain had American industrial capacity in the Second World War, which capital ships would be completed?
Short answerThe Lion-class battleships and the planned carriers would be completed, including the later fleet carriers.
NotesThe counterfactual removes the industrial bottleneck that forced Britain to choose among major projects. The Lion class would likely be completed rather than suspended. The carrier programme would also continue to completion, including additional ships such as the Implacable-class units. The historical gap reflected America's room to expand and Britain's exposure to bombing, rather than a lack of viable British designs.
