Forty County-class cruisers would inflate the whole treaty tonnage ladder

A British force of forty County-class cruisers implies roughly 400,000 tons of heavy cruisers and treaty allowances large enough to reshape American and Japanese construction.

Question

How would forty British County-class heavy cruisers affect 1930s cruiser construction in other navies?

Short answer

They would drive much larger treaty allowances for Britain and the United States, while Japan might lack the capacity to use its expanded share alongside the Yamato program.

Notes

Forty County-class ships already approach 400,000 tons of heavy cruisers, and Britain would also seek a substantial light-cruiser allowance. Parity would give the United States similarly enlarged limits, while the ratio system could leave Japan around 300,000 tons in each category. Japan might be unable to exploit the full allowance while also funding the Yamato program. Nominal treaty permission would not equal industrial capacity.
