USS R-15 (SS-92), also known as "Submarine No. 92", was an R-1-class coastal and harbor defense submarines of the United States Navy commissioned before the end of World War I.
Design
The submarines had a length of Template:Convert overall, a beam of Template:Cvt, and a mean draft of Template:Cvt. They displaced Template:Convert on the surface and Template:Cvt submerged. The R-1-class submarines had a crew of 2 officers and 27 enlisted men. They had a diving depth of Template:Cvt.Template:SfnTemplate:Sfn
For surface running, the boats were powered by two Template:Convert NELSECO 6-EB-14 diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Template:Convert Electro-Dynamic Company electric motor. They could reach Template:Convert on the surface and Template:Cvt underwater. On the surface, the R-1-class had a range of Template:Convert at Template:Cvt, or Template:Cvt if fuel was loaded into their main ballast tanks.Template:Sfn
The boats were armed with four [[American 21-inch torpedo|Template:Convert]] torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The R-1-class submarines were also armed with a single [[3"/50 caliber gun|Template:Cvt/50 caliber]] deck gun.Template:SfnTemplate:Sfn

Service history
1918–1931
Following shakedown, R-15 conducted operations in waters adjacent to the Panama Canal Zone. Based at Balboa, through December 1918, she returned to California, in January 1919, where she operated between San Pedro, and San Diego, until March. She then proceeded to Mare Island Naval Shipyard for overhaul prior to her transfer to Pearl Harbor's new submarine base, arriving there on 25 June 1919.Template:Sfn
When the US Navy adopted its hull classification system on 17 July 1920, she received the hull number SS-92.Template:Sfn
She remained in Hawaiian waters, participating in the development of submarine warfare tactics until 12 December 1930, when she got underway for the East Coast and inactivation.Template:Sfn
Decommissioned at the Philadelphia Navy Yard, on 7 May 1931, R-15 remained in the Reserve Fleet until ordered to New London, Connecticut, for activation in the summer of 1940.Template:Sfn
1940–1945
Arriving in the Thames River, on 9 September 1940, she was recommissioned 1 April 1941, and in June, sailed south for duty in the Panama Canal Zone. For the next three months she operated with SubRon 3. On 3 October, she got underway for New London, arriving on 23 October, and reporting for duty in SubRon 7.Template:Sfn
Patrol duties off the coast followed the entry of the United States into World War II. In February 1942, she again sailed south. In early March, she patrolled in the Virgin Islands area, then shifted to training and patrol duties out of Trinidad. Relieved in early August, R-15 returned to the Virgin Islands, thence continued on to Bermuda, and in the fall, back to New London.Template:Sfn
In December, R-15 returned to the Caribbean Sea and operated out of Guantanamo Bay. Further training duties in waters adjacent to the Virgin Islands, and off Bermuda, followed, and in April 1944, she returned to New London. Following ten months of operating out of New London, R-15 returned to the Bermuda area, on 14 December. For the remainder of the war she operated off the Florida coast, and from 1 March to 17 June 1945, from Guantanamo Bay. On 2 September, she put into Key West, to complete her last tour.Template:Sfn
Fate
R-15 was decommissioned 17 September 1945, struck from the Naval Vessel Register on 11 October 1945, and sold the same month to Macey O. Scott, of Miami.Template:Sfn
