That's actually just Japan having more resources in general to use on them, since by now they've mostly given up on revuilding the carrier fleet.Japan managed to complete eight I-400 class subs? Damn, those soviet resources have been useful.
At the runways/planes. I figure a big bomb is a big bomb, it'll do something.Question: what targets were the Okhas fired at in this raid? They're anti-shipping weapons normally, and probably are not worth use against ground targets.
