You are wrong.
kaidai has more air, longer dive time. And it is faster.

just like the guy above me said... nothings wrong with kaidai... you'll have also additional support slot on it to put an engy or rep or whatever you want to put in that additional slot

and other thing, the type 95 torps is 3knts faster than the type89 torps

and this sub can still sink a bb easily and able to reach the other side submerge longer than the junsen...

just expect to lose rear tubes on ss4-ss5.5/6

ss4= you'll gain 4 front tube and lose rear tube (8 front tube 0 rear)
ss5 = you'll lose 2 front tube (6 front tube 0 rear and ability to carry tbs)
ss5.5/6 = you'll regain those 2 front tube (8 front tube 0 rear and ability to carry tbs)


if you played km ss2 to ss5 you'll get to used to 4 front tube throughout your grind

 

BEST IJN SS

still prefer this...

well, you can't expect every ss to have perfect set-up. 

For example, UK SS5 has only 4 tubes IN TOTAL, it is like a joke. 

to not open another topic i continue with this

updating BO info a comparison before and after

things to know except 1 ff the others was sunked by proximity explosion

destroyers and cruiser, some one receive "the touch of grace" in same way

28 Battleships sunks sounds great, but not except 1 carlomagne run aground in islands map

27 remaining was bb1, bb2 without bulge armor someone fly away with 3 torps

Total gameplays was over 350 to gain the million and fourth part experiend points

the outcome is very poor (is my personal opinion)

and over "perfect set-up" somethings are desirable like

 

And

I continue saying submarines, needs to be improved

like sonarman in submarine not detect other submarines in surface or detect distance is half

or is that mine is deaf

Another day we speak about speed surface or submerged, and we have a marking range of 15 if torps only reach from 8 to 10?
