The common-hull rule extends across battleships and carriers, while destroyer changes occur only between complete flotilla batches. Repetition would simplify training and parts support and make better use of naval personnel who historically ended up in ground formations. More hulls would improve German force generation, especially after destroyer losses. Yet Britain and other rivals possess enough infrastructure to answer additional German construction, leaving Germany in a strategic catch-22 between quality and quantity.

What a common capital-ship hull changes
A single hull family improves crew training, logistics, and hull numbers, but cannot erase Germany's industrial disadvantage against larger naval powers.
