'''USS ''R-25'' (SS-102)''' was an [[United States R-class submarine|R-class coastal and harbor defense submarine]] built for the [[United States Navy]] during World War I.
==Description==
The R-boats built by [[Lake Torpedo Boat]] Company (''R-21'' through ''R-27'') are sometimes considered a separate class from those of the other builders. The Lake boats had a length of {{convert|175|ft|m|1}} [[length overall|overall]], a [[beam (nautical)|beam]] of {{convert|16|ft|8|in|m|1}} and a mean [[draft (ship)|draft]] of {{convert|13|ft|11|in|m|1}}. They [[displacement (ship)|displaced]] {{convert|497|LT|t}} on the surface and {{convert|652|LT|t}} submerged. The R-class submarines had a crew of 3 officers and 23 enlisted men. They had a diving depth of {{convert|200|ft|1}}.<ref name=f7>Friedman, p. 308</ref>
For surface running, the boats were powered by two {{convert|500|bhp|lk=in|0|adj=on}} [[diesel engine]]s, each driving one [[propeller shaft]]. When submerged each propeller was driven by a {{convert|400|hp|0|adj=on}} [[electric motor]]. They could reach {{convert|14|kn|lk=in}} on the surface and {{convert|11|kn}} underwater. On the surface, the Lake boats had a range of {{convert|3523|nmi|lk=in}} at {{convert|11|kn}}<ref name=f7/> and {{convert|150|nmi|abbr=on}} at {{convert|5|kn}} submerged.<ref name=f7/>
The boats were armed with four 21-inch (53.3&nbsp;cm) [[torpedo tube]]s in the bow. They carried four reloads, for a total of eight torpedoes. The R-class submarines were also armed with a single [[3"/50 caliber gun|3"/50 caliber]] [[deck gun]].<ref name=gg9>Gardiner & Gray, p. 129</ref>
==Construction and career==
[[File:USS R-26, R-25, R-27, and R-23.jpg|thumb|USS ''R-25'' in Bridgeport during 1919]]
''R-25'' was [[laid down]] on 26 April 1917 by the Lake Torpedo Boat Company in [[Bridgeport, Connecticut]]. She was [[ship naming and launching|launched]] on 15 May 1919 sponsored by Mrs. Richard H. M. Robinson, and [[ship commissioning|commissioned]] on 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, Panama|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.
