S-11 (SS-116) was laid down on 2 December 1919 by the Portsmouth (N.H.) Navy Yard; launched on 7 February 1921; sponsored by Miss Anna Eleanor Roosevelt; and commissioned on 11 January 1923, Lt. Wilder D. Baker in command.
Supplementing duties along the northeast coast, S-11 visited Guantanamo Bay, Cuba, in 1923, and St. Thomas, Trinidad, and Coco Solo in 1924. Sailing from New London, Conn., on 29 September, via the Panama Canal and California, she visited Hawaii from 27 April to 25 May 1925, before returning to New London on 12 July. S-11 operated in the Panama Canal area from January through April 1926, visited Kingston, Jamaica, from 20 to 28 March 1927, and served again in the Panama Canal area from February into April 1928. From 1929 into 1936, S-11 operated almost exclusively in the Panama Canal area, but visited Washington, D.C., from 15 May to 5 June 1933. Departing Coco Solo on 13 June 1936, S-11 arrived at Philadelphia on the 22nd, and was decommissioned there on 30 September.
S-11 was recommissioned on 6 September 1940 at Philadelphia. After voyages from New London to Philadelphia, Bermuda, and St. Thomas in 1941, S-11 arrived at the submarine base, Coco Solo, Panama Canal Zone, on 5 October that year. S-11 served in the Panama Canal area from then into June 1943, and next at Trinidad into February 1944. Following overhaul in the Panama Canal area, S-11 sailed in July via Aruba to Trinidad, where she operated into October. Arriving at Guantanamo Bay on the 26th of that month, she served there into January 1945. After a voyage to the Panama Canal area, she sailed from there on 8 February, arrived at New London on the 24th, and at Philadelphia on 28 March. S-11 was decommissioned, on 2 May of that year, at Philadelphia and was struck from the Navy list. She was sold on 28 October 1945 to Rosoff Bros., New York City. Resold to Northern Metals Co., Philadelphia, Pa., on an unspecified date, she was scrapped.
