Two rudders. The props and rudders are in the same setup as the North Carolina, South Dakota and Iowa classes.

Not the way you've drawn it now. Right now the rudder is either on the centerline or further to port.

I used this configuration for the rudders and the propellers:

I got that, but the way you've drawn your rudder it's either on the centerline or further to port

All other drawings of other US battleships and other ships with two rudders has it drawn the same way.

Not quite. In order to show what you're trying to show you would have to draw something along these lines:

Unless the area aft of the props are completely flat that is, but as far as I'm aware, it isn't.

Around this time the 3-inch/50 AA gun was being supplanted with the 5-inch/25, the 5-inch/38 was the primary DP gun of WW2. The 5-inch/51 is an anti-surface gun, some of which were later used as shore batteries (most notably at Wake Island).

It really looks to me like your ships have 3 shafts and 1 rudder as well...

According to springsharp the Delaware 1942 refit is underpowered or underperforming relative to the displacement.

It should, as she is basically armed the same as the South Dakota, but with a far thinner deck (1.5" vs 1.5"+6") and lacks SoDak's heavyweight 'command and control' equipment... but is over 3000t heavier (standard displacement).

The deck armor need a massive increase- to at least 4" and possibly 5"- and a decapping deck needs to be added- another 1.5" or so- then displacement needs to be trimmed as much as is practicable to leave the hull full enough to support the guns.

5"/51s were developed as surface weapons, with a low angle. Not suitable for AAW. Other than that, it is still a great design.

By the way, if you want additional heavy AA weapons, the 5"/25s would make a great weapon for an inter-war period battleship design like this.
