January 21-April 22, 1930 London Naval Conference The American, British, French, Italian, and Japanese governments negotiated a naval disarmament treaty regulating submarine warfare and the size of submarines.

The American, British, and Japanese governments also agreed to scrap certain warships by 1933, and allocated tonnage limitations in other categories. As a result, one Japanese, three American, and five British capital ships were scrapped. The signatory states also included an "escalator clause" which permitted increases in specified warship tonnage due to national needs (demanded by the British in the event that France or Italy threatened the naval status quo). The agreement established a permanent naval parity between the United States and Britain, which reflected a major change in British naval policy.
