Would Australia prefer a Vanguard-type ship to an improved King George V?
Short answerExisting 15-inch guns and support arrangements could make the Vanguard route cheaper, while Britain retained its King George V and Lion types.
NotesThe proposal also fits the Australian interest in a battlecruiser-type capability. Reusing established armament offers a practical reason for choosing that route. This is a counterfactual preference, without a claim that Australia had a funded order ready to place.
