How would US treaty calculations change if Britain entered the negotiations with many more heavily armed capital ships?
Short answerThe United States would respond in construction, but the greater gun and displacement scale would raise the treaty ceiling and impose especially severe costs on Germany.
NotesThe larger hypothetical British battle line increases both the number of heavy guns and the displacement needed to carry them. A Hood with four triple 15-inch turrets would probably approach 45,000 to 50,000 tons rather than fit a 35,000-ton ceiling. The United States has the industrial capacity to respond with triple or even quadruple turrets, and Japan would also alter its designs. Germany faces the hardest problem because every response adds infrastructure, money, and production demands that its naval program is poorly placed to absorb.
