One coul be that each ship ahce theri space for armament other is that not ahve enoght lvl
to see all the guns posible

gun space is niothing else then a kind of a placeholder.
for example 300 has ur ship in R slot (mainguns). the guns need 270. u can fit them
and still have 30 points left for ammo.
the weight of the guns has nothing to do with the ship or slots.

the tripple 15" cant be mounted on the bissy. that guns are only for the o-pro-2 or
higher. opro-2 and bissy are both bb3 ships. the one and only tripples u can fit on
bissy..are the crappy tripple 11" guns with a nice range but very low damage.

they have similar weight so that O2 using bissy guns won't gain even more speed advantage

however they require much larger space which means they don't fit in bissy's R slots

The Opro's x3 have the same weight as the dual 14.96's so it confused me. And i
found nothing stating it was only for an o pro.

Im sorry if i took you away from something important but if my questionwas too time
consuming for you, dont answer my simple question then, and please keep your
comments to yourself.

That being said, thank you very much for your prompt answer. The information part
was truly appreciated :)

those are Opro2 guns (using 3x14,96o L on 3 mount)

bissy cant handle them. (using 2x14,96b L on 4 mount)

check the space needed for said guns and the space availble on a ship gun slot next time
before asking question maybe...or search?
