Anglo-American parity if later naval conferences failed

What might Anglo-American naval strength have looked like if later treaty conferences failed?

The two navies might have reached informal parity in carriers and capital ships, with Britain still fielding more cruisers and destroyers.

If the Washington framework survived while the later London conferences failed, Britain and the United States could settle near parity in top-tier assets. Their carrier and capital-ship forces might be roughly comparable because American congressional concern for national status favored matching the most prestigious ships. Britain could still retain an advantage in cruisers and destroyers. Congress was less likely to fund exact parity across the whole fleet.
