Naval search is a sore point for me as the japanese side:i would rather use Nettys as
strike aircraft,i can build a few hundred H8K's, but not enough groups use them.
So i build Jakes in large numbers,removing the second squadron from BB's & CA's,
I transfer them to one of capacity 9 AV's & resize them. Then either use them
as land based naval search,or leave them on the AV as a scouting TF for the KB.
If i lose any I-Boats, i recall the sunk squadron,change to Jakes,& then resize to
9 planes. Might be a bit gamey,but the IJN needs all the help it can get.
