The problem with Type 3 is that the battleships themselves capped their day battle attack power without Type 3, thanks to combined fleet's modifier. Type 3's bonus is pre-cap, while AP Shell's post-cap.

I think that's the reasoning.

Of course it doesn't mean your attack won't miss. Or rolling high-armor value.
