Could Australia have received a Lion-class battlecruiser to replace HMAS Australia after the 1922 Washington treaty?
Short answerA Lion is unlikely, but Tiger becomes plausible if Dominion navies receive separate treaty allowances for one trade-protection flagship apiece.
NotesTiger is the preferred hypothetical replacement for HMAS Australia. The scenario requires the Washington treaty powers to count Australia, Canada, and India separately from Britain's capital-ship allowance. A compromise might permit each Dominion one weaker battlecruiser for trade protection and flagship duties without adding that tonnage to the Royal Navy total. Older battlecruisers could then be distributed among Imperial navies, with Australia receiving the strongest candidate.
