The logistics trap in Australia's missile drone ships

What are the advantages and disadvantages of Australia's planned uncrewed missile ships?

They can carry expendable forward missile capacity and rotate home after firing, but sustaining that shuttle requires many hulls and creates a vulnerable resupply route the enemy can attack.

The uncrewed ships carry useful firepower that can fire, withdraw, and be replaced without sending the main combatant home. The logistics chain remains demanding: gaps still consume the parent ship's own missiles, many drone hulls are needed to keep the circuit moving, and an opponent can attack the route until the navy must escort convoys of its supposedly independent auxiliaries.
