I found another one while I did a battleship vs battleship scenario. I had a 130k ton beast with a quad 50.6 cm sitting in the center, and 6 triple 38.1 cm cannons.
I expected to fight a worthy foe, but I should have known better:
Yes, your silly eyes arent deceiving you:
The 30k ton battlecruisers going along were far more threatning with their 3x triple 33 cm.
Jokes aside, Im pretty sure this will be the absolute worst nightmare of any light/medium ship, its a somewhat fast for a 90 thousand ton battleship, its armor is decent, and that is a strong 24" torpedo armament...
But I dont think lots of butterflies can destroy a tank... especially one with 55 cm of side armor...
Also, the AI used huge barbettes for these tiny guns...
And, if you are ever in this situation, make sure to add a 17.8 cm double to further increase the accuracy penalty.
