Run the 16" Mark 2 Ls (duals) with LHE. Armor it like you would any other US BB, 0.2 belt and bulge until you lose a knot, then remove 1 bulge.

Any tips to getting the a lot attack out of this as well? i barely get anything on it

Wait for an opening. Rush the enemy, get some attack, rinse and repeat.

I'm in the TN 1945 right now and can give a little advice. The above info is correct so I am not here to argue against their points of view.

We are in a BB 2.5 and cannot line fight like our higher tier BB team mates. But what we can do in the TN45 is give great AA support to the BB456. The TN45 plays best just behind the line and not in the way of the bigger BBs by keeping the bomber whores off our massive battleships who can do the line fight. Keep the enemy blind and you can sneak in like a ninja and get 1 or 2 salvos on BB456. I have even sunk a BB5 by keeping him blind and being 5-10 degrees under his max angle.

I run .5 deck, .5 belt, and enough bulge to drop a knot and then remove the bulge so you gain back that lost knot. We are SLOW so only engage when you snipe all the scouts out of the sky and you know the enemy is blind. I use the 5" AA guns but run out of ammo 3/4 through a battle with 5-6k credits of killing airplanes. Keep those small ships away so they don't give free sight but always try to engage BB456 or CV456. If you want to use the 3" AA guns to give you more ammo be my guest but it will take more direct hits to kill higher tier planes.

If played right you can easily gain 30k exp per match with a good average of 20-25k exp.

Have fun and good luck!

Generally speaking, BB2s can`t do anything worthwhile on the front line, so just stay a bit behind of the front and shoot at Kitas and rushing pity lemmings.
When the line collapsed, you push F button deliberately, and terminate badly damaged BB5s one by one.

So you can get big deals with minimum effort, and team will win also, hopefully.
