Six month to one year delay in US victory. New and far better ships and aircraft are coming and coming fast. Carrier and fast battleship construction gets sped up even more. The Navy probably works harder on getting the Corsair deck qualified. The Navy bites the bullet and transfers Ranger to the Pacific (they know she won't last long out there but they need the hulls).
The Japanese would retain the advantage in aircraft carriers until about early 1944, so this significantly delays any advance into the Pacific.
