The Gwin was named after William Gwin, a member of the US Navy during the Civil War who served with the Mississippi Squadron. He was fatally wounded at the battle of Haines Bluff on the Yazoo River (27 December 1862) and died on 3 January 1863.

The Gwin was launched at Seattle on 22 December 1917. Progress on her then slowed down, and she wasn't commissioned until 18 March 1920. Some of that delay can be explained by the end of the First World War, but not all - plenty of ships launched after her were commissioned in time to take part in the war.

On 26 April 1920 the Gwin left Puget Sound at the start of a journey to her base at Newport, Rhode Island. On the way she visited a number of Californian ports, and passed through the Panama Canal. She reached Rhode Island on 2 June 1920, at the end of what turned out to be her longest voyage.

Over the next two years the Gwin operated along the US east coast, reaching as far south as Charleston. She was decommissioned on 28 June 1922, and remained in the reserve at Philadelphia until she was struck off on 25 January 1937. Her name was reused on the Gleaves class destroyer USS Gwin (DD-433). DD-71 was sold for scrap on 16 March 1939.
