If the Second World War did not happen, how many Vanguard-class battleships might Britain build?
Short answerProbably three or four, ordered one at a time until the Royal Navy approached its desired capital-ship strength.
NotesWithout the Second World War, the Royal Navy might order Vanguard-class ships one at a time until it reached its desired capital-ship strength. The estimate is three or four Vanguards within a fleet aiming for about twenty-five capital ships. The passage gives a force-planning estimate for the counterfactual. It is not presented as a documented historical building schedule.
