Why a smaller Bismarck needs a complete redesign before comparison

How would Denmark Strait change with a treaty-compliant Bismarck?

A reliable answer would require the full redesign and simulations; gun caliber alone cannot establish the result.

Reducing Bismarck from 41,700 to 35,000 tons standard displacement requires a saving of 6,700 tons. A meaningful comparison would need to establish which capabilities were removed and how the design became more efficient. Changing the guns is only part of that calculation. Without the resulting ship design and simulations, a precise Denmark Strait outcome would be guesswork.
