Built with the same hull as an Alsace class, the 424 class has a 50 long hull section added in to accomodate an extra 22 inch heavy gun turret. Also, the rear mast has been strengthened with a tripod and an extra deck for spotting purposes.
So this is what boat anarchy looks like, giant guns nailed to ships that are too small to support them.
But yes, this hull actually came first, but there were quite a few issues with the guns that I decided to wait.

Activation group 1 and roll+pitch to control main guns
Activation group 2,3 and roll+pitch to control port/starboard guns.
Activation group 7 for missiles. (Of course they don't work)
VTOL slider controls the propeller pitch. Up=forward down=reverse. 1/2 up/down for best effect.
Trim slider to control rudder.
