How might Campania joining the Grand Fleet and successful carrier reporting have changed Jutland and naval aviation?
Short answerDecisive aerial intelligence could have altered Jutland and accelerated the arrival of full-length flight-deck carriers, perhaps also changing Washington Naval Treaty terminology.
NotesThe second counterfactual imagines Campania reaching the Grand Fleet and both carrier groups reporting successfully. Information from Rutland would then move through Engadine, Napier, Beatty, and Jellicoe without the historical breaks in the chain. If those reports changed the outcome of Jutland, naval leaders would have received a dramatic combat demonstration of aviation's value in 1916. Full-length flight-deck carriers might consequently have appeared sooner. A stronger early record for carrier effectiveness could also have altered the terminology and assumptions applied to aviation ships in the Washington Naval Treaty.
