Reason I like buying subs for my japan is cheep fodder. Usually if US goes pacific i’m stalling to hold on to my money islands just long enough to crush russia, not to actually fight the US. Because of that, cost is everything to me.
If I wanted an actual show down i’ll focus on fighters (as my 3 carriers can typically allow 12 to attack if based properly) and bombers with a sprinkling of DDs.
