What one American BBG(X) would do for Australia

Would one future large US warship used as an Australian flagship materially change national power?

In the scenario, nuclear propulsion, missile capacity, and the battleship label give the ship particular diplomatic status when it is available.

The hypothetical Australian flagship is distinguished by nuclear propulsion and a large vertical-launch missile capacity. Its contribution would depend on the single ship being available. The discussion also treats the word 'battleship' as a diplomatic signal, giving the vessel greater perceived status than the labels 'cruiser' or 'destroyer'. Nuclear propulsion and naming are the features emphasized; the exchange does not set out a complete assessment of Australia's resulting combat power.
