British armor quality benefited from a longer industrial buildup and opportunities for skilled workers to keep practicing under the treaty system. Nelson and Rodney preserved capital-ship design and armor experience, while the County-class cruisers sustained additional plate production and quality control. The United States suffered a sharper contraction after its earlier buildup and later had to recreate infrastructure and competition at scale. British continuity offered a temporary quality advantage, but American investment could overtake it once resources and production expanded.

How treaty-era construction preserved British armor expertise
Nelson, Rodney, and the County-class program helped Britain retain armor-production knowledge while the United States rebuilt capacity after treaty-era contraction.
