Three jeep carriers.
For combat aircraft, I think I'd require that they actually saw combat, then look at effectiveness. The G4M was pretty ineffective, and virtually all of them were shot down
And they were pretty "fairly" attacked, unlike some of the planes slaughtered during the initial japanese expansion, or even the german invasion of the CCCP. In both cases the attacking AFs had such overwhelming numbers at the sharp end that aircraft quality is a non-starter, any planes would have been wiped out at the right odds.
