USS O-15 (SS-76), also known as "Submarine No. 76", was one of 16 O-class submarines of the United States Navy commissioned during World War I.

Design

The later O-boats, O-11 through O-16, were designed by the Lake Torpedo Boat Company, to different specifications from the earlier boats designed by Electric Boat. They did not perform as well, and are sometimes considered a separate class.Template:Sfn The submarines had a length of Template:Cvt 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 O-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 Busch-Sulzer diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Template:Convert Diehl Manufacture Company electric motor. They could reach Template:Convert on the surface and Template:Cvt underwater. On the surface, the O class had a range of Template:Convert at Template:Cvt.Template:SfnTemplate:SfnTemplate:Sfn

The boats were armed with four 18-inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The O-class submarines were also armed with a single [[3"/23 caliber gun|Template:Cvt/23 caliber]] retractable deck gun.Template:Sfn

Service history

Commissioning during the final months of World War I, O-15 saw brief war time service, on patrol along the Atlantic coast.Template:Sfn

After the war, she reported to the Philadelphia Navy Yard, where machinists and electricians worked on her until 20 September 1919, when she was reduced to "in commission, in reserve", at Cape May, New Jersey.Template:Sfn

She departed Philadelphia, in April 1920, and proceeded, via Jamaica, to Coco Solo, in the Panama Canal Zone, where she underwent overhaul and conducted experimental tests.

When the US Navy adopted its hull classification system on 17 July 1920, she received the hull number SS-76.Template:Sfn

Conducting training cruises, she operated in and around Cuba, and the Virgin Islands, early in 1922, and returned to Coco Solo, in April.Template:Sfn

Fate

O-15 reported to Philadelphia, in November 1923, and decommissioned there 11 June 1924, after just five and a half years of service. Struck from the Naval Vessel Register on 9 May 1930, she was scrapped, under terms of the London Naval Treaty, on 30 July 1930.Template:Sfn
