Tommy Blackburn, CO of VF-17 said in mid-February of 1943 there was one new F4U-1 Corsair fighter ready for delivery at Floyd Bennett Field, New York and he picked it up.
VF-12 completed carrier qual by April of 1943. Two months after Blackburn picked up the F4U-1.
Starting May 1, 1943, VF-17 landed F4U-1's and eventually all pilots got their five traps. VF-17 deployed aboard Bunker Hill with new F4U-1A's from the factory September 10 of '43.
So, VF-12 and VF-17 successfully completed carrier qual with F4U-1's by April of 1943, a few months after the first F4U-1 was picked up from Vought. The Royal Navy/FAA didn't even get their F4U-1s until November of 1943. Seems the USN somehow figured out F4U-1 carrier ops
prior to the FAA even getting their airplanes.
Further, VF-12 and VF-17 qualified aboard Charger, an older, slower converted passenger liner. Most of Blackburn’s pilots had never landed aboard any carrier before; they were grass-green. From Blackburn's book:
“Moreover, Charger hardly qualified as a carrier; that spitkit rarely produced the 25 knots of relative wind over her flight deck that was considered the standard minimum for safe landing operations.”
VF-17 deployed aboard Bunker Hill (Essex class) with new F4U-1A's from the factory September 10 of '43.
From Blackburn's book:
The trip to the West Coast was uneventful, and they sortied from San Diego on September 28.
But a few days out, official lightning struck. VF-17 was detached from Bunker Hill, and ordered to the island of Espiritu Santo, to operate as a land-based squadron. The problem was one of logistics, not of operations. The high command knew that Blackburn's Corsairs could operate from a carrier. But as the only Corsair squadron in a Navy full of Grumman Hellcats and Wildcats, supplying and maintaining them would be a headache.
It really doesn't appear that the USN had any trouble developing carrier landing procedures for the F4U-1. It appears the reason for the land basing was, as previously mentioned, just a logistical solution to a problem of a mixed fighter fleet on carriers.
