After the Corsair became operational from carriers, another 570 some victories were claimed, Saxman. I should have clarified that, but was running out the door as I posted.
Sure, Corsairs were being flown off and on US carriers, starting with carrier trials on the USS SANGAMON on 25 September 1942, but I believe VMF-124 was the first US squadron to fly operations off a carrier, and VF-17 was the first US
Navy squadron to fly the Corsair off carriers.
Those are the facts as I understand them. If there is something wrong with that information, I'm always ready to accept correction to it. I'm not in this for a fight, whatever is right is right.

I understand Lt. Walsh was an ace in mid-May, 1943.
