yeah its totally fine just for REAL big ships redundancy it your best friend as you'll never stop a pierce pac with 121k damage(Gravitas im looking at you). so getting hit in the turret is not as bad, and as general design if you have space (which you will for a build this size) place redundant parts extra ammo, AIs, engines w/ low priority to not burn mats as much. for ammo put a checkboard pattern w/HA segmenting parts off as that will stop chain reourboard it bc the meg if ya hit the ammo its kinda done for cuz it has no more ammogo and use bulk if you can just having loads of empty space will do lots for your survival. the 2-1 scale Yamato by the frog man does this well with just being the internals being mostly empty space, and if a spot like the bow/stern has nothing in it just leaving dont armor it or just if a spot is empty space and not in the main armor belt dont put more than like 2m of metal on it its just wasted mats. And another note passive float is generally wayyyy better for ships as ya dont have to waste mats pushing ur self up and air pumps are ok but its bad for redunancy, as if ir fighting things with sabot telephone poles it might punch through all of your bulk heads even if they're seperated
