USS S-10 (SS-115) was a part of the second-group of S-3-class, also referred to as a "Modified Government"-type, submarine of the United States Navy.
With lessons learned with the earlier boats, and studies on German U-boats, changes were incorporated into the remaining "Government"-type boats that had not been laid down yet. A stern mounted torpedo tube was added in the aft of the boat, along with the modified bow planes first tested on and .
The "Modified Government"-type had a length of overall, a beam of , and a mean draft of . They displaced on the surface and submerged. All S-class submarines had a crew of 4 officers and 34 enlisted men, when first commissioned. They had a diving depth of .
For surface running, the "Modified Government"-type were powered by two MAN S6V45/42 diesel engines built by the New York Navy Yard, each driving one propeller shaft. When submerged each propeller was driven by a Westinghouse Electric Corporation electric motor. They could reach on the surface and underwater. On the surface, the modified S-3-class had a range of at , or at , if fuel was loaded into their main ballast tanks.
The boats were armed with four torpedo tubes in the bow and one the stern. They carried 9 reloads, for a total of fourteen torpedoes. The "Modified Government"-type submarines were also armed with a single /50 caliber deck gun.
The Bureau of Construction & Repair (BuC&R) was given the job of correcting the "Government"-type's slow diving times. To accomplish this, starting with S-8 and S-9, they moved the bow planes below the water line and rigged them to be permanently in the out position. Due to the success of these modification, S-10 to and to , would also be outfitted with the new planes.
S-10s keel was laid down on 11 September 1919, by the Portsmouth Navy Yard, in Kittery, Maine. She was launched on 9 December 1920, sponsored by Miss Marian Kingsbury Payne, and commissioned on 21 September 1922.
Following duty off the northeast coast, S-10 visited the Panama Canal area, St. Thomas, Virgin Islands, and Trinidad and Tobago, in early 1924, and completed that year along the northeast coast.
Sailing from Boston, Massachusetts, on 19 February 1925, S-10 voyaged via the Panama Canal and California, to the Territory of Hawaii, arriving on 27 April. She returned to New London, Connecticut, on 12 July, and completed that year in New England waters.
In addition to duty out of New London, from 1926 to 1928, S-10 operated in the Panama Canal area, from FebruaryâÂÂApril 1926, visited Guantanamo Bay and Kingston, Jamaica, in March 1927, and served again at the Panama Canal, from FebruaryâÂÂMarch 1928. From 1929 to 1936, S-10 served almost exclusively in the Panama Canal area, although she visited Memphis, Tennessee, from 11 to 15 May 1933, and was in reserve, with a partial crew, at Coco Solo, from 1 July-27 November that year.
Departing Coco Solo, on 30 March 1936, S-10 was decommissioned at the Philadelphia Navy Yard, and struck from the Naval Vessel Register, on 17 July 1936. She was sold for scrapping, 13 November 1936.
