4^th Chief of Naval Operations: 14 November 1927 – 17 September 1930

The onset of the Great Depression and the strictures of the “Treaty Navy” were challenges during the term of Admiral Charles F. Hughes.  In 1927, talks intended to extend tonnage limits to more classes of ships ended without agreements.  Another meeting was held in London in 1930, which resulted in a treaty increasing the number of ships allowed for Japan and raising overall tonnage limits on cruisers, which benefited the United States.
