My info has the SS with 16" guns.
At any rate the advantage has to go with the Germans who have far more experience. This experience runs from design and construction experience to operational experience, to the best technical support from experienced private enterprize and private acadamia, and to actual combat experience. We should expect the Bismarck to have superior firecontrol equipment and procedures. We should expect the Germans to have superior metalurgy and armour manafacture methods.
Entering a night sea battle is an awesome business.The enveloping darkness, hiding the enemy's.. seems a living thing, malignant and oppressive.Swishing water at the bow and stern mark an inexorable advance toward an unknown destiny.
