A surviving Force Z changes ABDA naval concentration

With Phillips and an intact Force Z still present, Allied naval forces could concentrate around a carrier and capital ship. That surviving force might make Phillips the focus of naval command instead of Admiral Hart, without implying that Hart lacked seniority or ability. Formidable and American units become plausible reinforcements, while Singapore offers a submarine base across Japanese routes into Borneo and the Dutch East Indies. The scenario still offers little prospect of saving the Philippines, but it gives the Allies a defensible center farther south. A larger flagship could accommodate British, Dutch, and American staff, reducing the need to coordinate scattered cruiser forces. Shared staff space and communications could also ease the handicaps faced by Karel Doorman. Japanese radio performance remains as it was historically, without an extra failure introduced to favor the Allies.
