The USS Sumner (DD-333) was a Clemson-class destroyer built for the United States Navy, representing the post-World War I naval expansion. Laid down on August 27, 1919, at the Bethlehem Shipbuilding Corporation in San Francisco, California, she was launched on November 27, 1920, and commissioned on May 27, 1921, with Lieutenant Commander Donald B. Beary in command. The vessel was named after Allen M. Sumner. Constructed as a Clemson-class destroyer, the USS Sumner featured the typical design of her class, optimized for speed and maneuverability, although specific dimensions and armament details are not provided in the source. Her service life spanned nearly nine years during a period characterized by relative peace, focusing primarily on training, patrols, and fleet maneuvers. Her operational history included notable deployments such as her participation in a 1924 mission to Veracruz, Mexico, to protect American interests during political unrest. That same year, she resumed routine operations along the U.S. West Coast. In July 1925, Sumner joined the Battle Fleet on a cruise to Australia and New Zealand, visiting ports such as Pago Pago, Melbourne, Sydney, Auckland, Lyttelton, Wellington, and Dunedin. After returning to the U.S. West Coast in September 1925, she continued her training and patrol duties. In 1927, Sumner transited the Panama Canal to join Atlantic maneuvers, operating as far north as Boston before returning to the Pacific. She remained active in Pacific operations, including deployments around Hawaii until her decommissioning at San Diego on March 29, 1930. Her name was struck from the Navy list later that year. Subsequently, she served as a barracks ship for submarine crews and as a structural testing platform until her hull was sold in 1934 under the terms of the London Naval Treaty, marking the end of her maritime service.
