The 1930 treaty provisions deferred capital-ship replacement from 1931 through 1936 and named American, British, and Japanese ships for disposal or training conversion. France and Italy retained rights to replacement tonnage that they had been entitled to lay down in 1927 and 1929. This produced an institutional contradiction: the signatories accepted another building holiday in 1930, then Britain informally abandoned the Ten Year Rule only two years later. The result was scrapping without a compensating stream of modern replacements.

The treaty text postponed replacement keels, required further disposals, and extended a construction pause just before governments abandoned the Ten Year Rule.
