CA '41-Beta
An alternate version of what became
Bauamt's CA'41, this twelve-gun heavy cruiser retains substantial similarities to the eventual design, retaining the entire motive power and electrical plant and stern arrangements. Eventually rejected due to the increased cost, increased crew requirements, even with the same extensive (and expensive) automation present in the CA'41 design and because the new Bruno turret in fact complicated the AA firing arcs for the 128mm DP guns.
