Could a carrier-backed ABDA Command delay Japan long enough for a British or American fleet to arrive?
Short answerNo isolated answer is reliable because the scenario has already changed carrier losses, Taranto, Allied deployments, and Japanese calculations.
NotesA simple survival time for ABDA is impossible because the carrier programme has already changed the forces reaching 1941. Courageous may avoid anti-submarine duty, Glorious may receive enough reconnaissance warning to escape Scharnhorst and Gneisenau, and more fleet carriers could then be available for Taranto. A larger strike might change the Italian fleet and the distribution of British strength between the Mediterranean, Atlantic, and Far East. Japan would also evaluate a different Allied carrier threat before choosing war against Britain and the United States. This long counterfactual becomes a chain of interacting decisions rather than a single extra unit inserted into the historical campaign.
