[Spaceships] Please look over my ship designs

[weby]

The iron duke seems to have broken stat list:
both the tonnage and armor are wrong.

Further it does not seem to be a battleship in idea, being almost unarmored like the destroyers. I would expect something called a battleship to devote a lot more of the mass to armor.

The Dymka seems somewhat strange in armament, with so many major batteries and no spinal battery.

Overall most of your designs seem kind of low armored and yet with low ECM, making them easy to hit and damage with comparable weapons. They seem to be designed for that anti piracy patrol, with little thought given to fighting warships.
