What happens if a carrier-supported Force Z survives with only moderate damage?
Short answerIt probably becomes the fleet around which ABDA command forms in Southeast Asia.
NotesThe question changes the opening Far East disaster by giving Force Z carrier support and survivable damage. The surviving force at Singapore would probably become the core around which ABDA command organizes. That would preserve experienced ships and a recognizable command structure at the moment Allied forces were trying to coordinate. The answer points to an important counterfactual mechanism: survival matters for both hull numbers and the coalition headquarters and force package available next.
