The scenario uses three German yards capable of large-hull construction and compares historical ship costs. A long production run should become cheaper as yards reuse drawings, tooling, supply arrangements, and accumulated knowledge. The falling unit cost of Britain's Type 23 frigates provides a later example of the same learning effect. The central gain comes from avoiding revolutionary redesign between small batches, rather than finding a magically cheap battleship.

Why repeated construction becomes cheaper
Repeated Scharnhorst-derived builds reduce cost and disruption compared with moving to wholly new Bismarck and Graf Zeppelin designs.
