USS Gwin (DD-71) was a Caldwell-class destroyer built for the United States Navy, serving briefly from 1920 to 1922. As one of six ships in her class, she represented a transitional design between earlier "thousand-tonners" and the mass-produced destroyers of World War I. The Caldwell-class introduced the innovative flush deck design, making USS Gwin one of the first "flush-deckers," which were known for being particularly wet in heavy weather conditions. Her specifications included a standard displacement of 1,262 long tons and a deep load displacement of 1,379 long tons. She measured 315 feet 6 inches (96.2 meters) in length, with a beam of 30 feet 7 inches (9.3 meters) and a draft of 8 feet 10 inches (2.7 meters). The vessel was crewed by five officers and 95 enlisted men. Power was provided by two Parsons steam turbines, each driving a propeller shaft, with steam generated by four Thornycroft boilers. The turbines produced a total of 18,500 shaft horsepower, enabling the ship to reach speeds of up to 30 knots (56 km/h). Fuel capacity allowed for a range of approximately 2,500 nautical miles at 20 knots. Armament comprised four 4-inch (102 mm) guns in single mounts, along with initial anti-aircraft armament of two 1-pounder guns, later replaced during World War I by two 3-inch (76 mm) AA guns. Additionally, the ship was equipped with a dozen 21-inch (533 mm) torpedo tubes arranged in four triple mounts, and during wartime, a "Y-gun" depth charge thrower was added for antisubmarine warfare. Launched on December 22, 1917, by the Seattle Construction & Drydock Company, Gwin was commissioned on March 18, 1920. Her operational history was brief; after departing Puget Sound in April 1920, she transited the Panama Canal to reach Newport, Rhode Island, where she participated in operations along the U.S. East Coast as far south as Charleston. She was decommissioned in Philadelphia in June 1922, remained inactive until her name was struck from the Navy List in 1937, and was ultimately sold for scrapping in 1939. USS Gwin's short service reflects her role as part of the transitional naval design during the post-World War I era.
