Big seaworthiness concerns about this vessel.
Very good study with pictures showing comparative pitch and roll video clips in wave tank and sea trials.

Wow, that seriously does not look good. Where’s the solution to the vulnerabilities? They all but admit heavy seas could rip the forward deck gun right of the ship and flood the hull!
In very violent sea states, given a large volumes of water flowing over the gun mount housing, as the bow submerges below the water, perhaps sufficient in scale and velocity to lift if not wash away (exfoliate) the forward AGS gun mount from the weatherdeck, flooding the compartments below.
