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.
