What would change if Canada, Australia and New Zealand retained or received Queen Elizabeth-class capital ships?
Short answerSeparate Commonwealth fleets could complicate treaty limits and force opponents to allocate more heavy ships to counter them.
NotesIndependently held Commonwealth capital ships would complicate the Washington treaty system, likely forcing a decision over separate signatory status and tonnage. Canada might retain three Queen Elizabeths while Australia and New Zealand operated a combined battlecruiser force as separate treaty participants. Canadian yards could then modernise both local ships and some Royal Navy sisters, spreading refit capacity across the Commonwealth. Modernised dominion ships would impose extra planning burdens on German and Japanese forces before a battle was ever fought. Even older capital ships can shape strategy by forcing an opponent to commit heavier assets elsewhere.
