How might the US Navy differ if Willis Lee survived 1945 and later became Chief of Naval Operations?
Short answerThe clearest possible effect is a different surface-fleet and cruiser policy; a specific shipbuilding program cannot be inferred from the answer.
NotesIf Willis Lee had survived his 1945 heart attack and later become Chief of Naval Operations, his strongest influence would probably have fallen on the surface fleet. Cruiser policy is identified as one area that might have developed differently. No specific class, budget, or force plan is supplied, so a more detailed procurement outcome would be speculation. Lee's gunnery and surface-warfare experience makes cruiser policy a plausible area of influence.
