Max tonnage is 34950. Mine is around 30400 t right now, with 7 inch deck and 6.5 belt (it can mount more but I needed to trim it down to fit the Reqired tonnage for the sink the Hood mission). Mine tops out atm 34 knots.

The guns it that are worth using in it are either 3 triple turrets which mount 3 12" guns, 3 turrets which mount 2 14" guns as seen on the Kongō and Ise or the Amagi/Nagato's 16" guns that you can unlock at level 45.
