Early '44 looks possible at first glance. IDK about "decimating", but more severe IJN losses at *Coral Sea is readily in reach, given Doolittle stays home (because the U.S. is doing better, there's no need for the morale boost: is that reasonable?)zert said:No guesses but when more tankers, transports,and hopefully more IJN carriers are sunk earlier, the can Allies advance sooner. Taking an unqualified guess the Marianas might get taken in early 44. Especially if an alt Coral Sea can inflict more casualties and the US does not lose any carriers. If the Port Morsby invasion forces can be decimated so much the better.
