London Naval Conference

London Naval Conference After the Washington naval conference, a second disarmament conference met at Geneva from 20 June to 4 August 1927, but failed to agree on further reductions in naval forces. The US strongly backed a British initiative to conduct another round of arms reduction talks at London among the five largest naval powers. Between 21 January and 22 April 1930, France and Italy walked out, but the US, Britain, and Japan negotiated their own treaty. They modified the Washington conference’s formula for dividing naval tonnage among themselves from 5 (US): 5 (Britain): 3 (Japan) to 10:10:7, so that Japan could add more destroyers, light cruisers, and submarines. They also extended the moratorium on warship construction through the treaty’s expiration of 31 December 1936. The treaty called for scrapping 5 British, 3 US, and 1 Japanese capital ships (those displacing over 10,000 tons). The Senate confirmed the treaty on 21 July. Further attempts at arms reduction were made at Geneva in 1932 and 1933, but made no progress. Japan formally denounced naval disarmament on 29 December 1934 and in January 1936 announced its intention to build a fleet equal to those of Britain and the US. In 1938 Congress funded a major expansion of the US Navy.
