So lets estimate 40% of US fighter production went to the Pacific - 40% of 99950 = 39,980 and Japan produced 30,447. Roughly a 4:3 ratio.
I'm not willing to assume this at all for one reason. First let me say I admit I don't have a document in front of me that says x number of planes went to this theatre, but I do have the reference document I linked and this statistic alone I think proves about 80%-90% of naval aviation aircraft operated in the Pacific theatre.
Total action sorties by theatre for US navy and marine air:
Central Pacific.....152,443
South Pacific.....41,204
Southwest Pacific.....88,358
North Pacific.....790
Atlantic.....1,161
Southeast Asia.....117
Refer to page 18 of the document I linked above bottom of chart.
As you can see it appears the US navy and marines only flew 1,161 sorties outside the scope of WitP for the entire war. I think this is strong evidence that at a minimum 80% of navy aviation production should be allocated to the Pacific (probably more like 90% realistically). 40% of USAAF production is fine pending a source to prove otherwise, but no way you have a case for naval aviation.
