USS R-25 (SS-102)

USS "R-25" (SS-102) was an "R"-class coastal and harbor defense submarine of the United States Navy. Her keel was laid down 26 April 1917 by the Lake Torpedo Boat Company in Bridgeport, Connecticut; the R-boats built by Lake Torpedo Boat (R-21 through R-27) are sometimes considered a separate class from those built by Fore River Shipbuilding (R-1 through R-14) and Union Iron Works (R-15 through R-20). She was launched on 15 May 1919 sponsored by Mrs. Richard H. M. Robinson, and commissioned 23 October 1919 with Lieutenant Commander Charles A. Lockwood, Jr., in command.

At the end of November, "R-25" got underway for her homeport, Coco Solo, Panama Canal Zone. Arriving 11 January 1920, she was given hull classification symbol SS-102 in July and, except for overhaul periods at Balboa and on the East Coast, operated in the waters off the Panama Canal Zone until the fall of 1923. In November of that year she arrived at Philadelphia, Pennsylvania, and underwent inactivation overhaul. On 21 June 1924 she was decommissioned after just over four-and-a-half years of service. She was laid up at League Island until was struck from the Naval Vessel Register on 9 May 1930 and sold for scrap the following July.
