~~ So I looked into it since I had no idea , and Kasumi ' s AACI is a special type of AACI , so if you give them the same equipment , from the looks of it Kasumi has the better AACI capabilities . Nobody ' s sure by how much . GIANT DISCLAIMER THO , cuz I ' m looking at various sources and they all seem to assume you ' re giving Kasumi big radars so FuMo , type 14 , etc instead of the normal type 13 radar for destroyers . So yes Kasumi ' s AACI is probs better , but only if you give her bigger radars to play with . ~~~~ With that said , the static AACI bonus for common destoyers is 4 with two high angle mount radar and the static AACI bonus for Kasumi will only be 4 when she has 1 high angle mount AA machinegun radar . The variable bonus is 1 . 6 for common destroyers but uncertain for Kasumi so I ' m assuming it ' s a tad higher , so ultimately you have to ask yourself if you ' re willing to give up the extra firepower for an increase in AA capabilities . It was an interesting read , thanks for making me curious btw . ~~ I ' m an idiot read issm ' s post .
