I am speaking of the time period between the end of Guadalcanal and the beginning of the invasion of the Gilberts.
The carriers did not engage in any systematic day to day operations untill late 1943.
Land based fighters are what wiped out the best of the IJN, and in this case, it was the P38 and F4U. If you have a case for the F4F as being the ebst, lets hear it.
Syscom - why are you hung up on 'systematic' operations? So what? and what does that mean to you? How many IJN fighters did the P-38 or F4U shoot down over Rabaul or Gilberts or Truk or Santa Cruz or Coral Sea or Midway? Or more importantly, Guadalcanal.
Where do you want to make a case that the F4F wasn't the most important sea based and land based fighter in 1942?
Nobody is arguing that land based airpower was a major contributor to the decline of IJN - but the USN was the point of the spear except for Darwin and Port Moresby in 1942... and the last time I checked the USMC was still part of USN.
If you have read any of my posts you might recall that I am ambivalent about F4U vs P-38 as 'best', and lean toward the F4U. Why do you think I regard the F4F as even a consideration?
I am glad the F4F was in-theatre but I don't rank them as a candidate for either Best or Most Important...at least not after mid 1943, nor do I rank the F4U or P-38 or P-40 in the category of Most Important in 1942 in the ultimate defeat of the IJN airpower.
For that period the F4F and P-40 are the only real US candidates and the F4F was more important at Coral Sea, Midway, Guadalcanal, Rabaul, Truk and Gilbert Islands than the P-38 and F4U... the more I think about it, the P-40 was probably more important through early 1943 out of Port Moresby than the P-38...at least through mid to late 1943.
IIRC the 475th, 8th, 18th, 35th and the 49th were the top USAAF PTO groups.
The 49th wasn't fully converted from P-40's until mid 1944. The 475th wasn't in combat w/38 until May 1943 and not out of New Guinea Until Oct, 1944 when it moved to to Phillipines.
The 8th didn't convert to P-38s until June 1943. the 18th didn't convert to P-38s (from P-40's) until after they moved from Guadalcanal in mid 1943, and the 35th had only one squadron of 38's in nov 1942 (two P-40) but all three converted to P-47s in Nov 1943, then 51s in late 1944.
The IJN foes based in New Guinea were important at both Lae and Salamaua (?) and defending against Rabaul strikes, in the New Guinea campaigns but the P-38 was far less a factor than the P-40 until July/Sept 1943 timeframe.
When do you stipulate the IJN airpower was defeated? Before or after mid 1943?

So how important was P-38 to destruction of IJN in 1942-1943? Close to zero relative to P-40 until mid to late 1943 and early 1944.
