An early photograph of USS S.C. 20, probably around the time of her commissioning in 1917. She carries her original armament, including a Hotchkiss gun forward and a Davis gun amidships, both of which later would be replaced.

USS S.C. 20 at the New York Navy Yard in Brooklyn, New York, on 15 September 1917, about five weeks before her commissioning. At right are the bows of two other SC-1-class submarine chasers, both unidentified.

USS SC-20, until July 1920 known as USS Submarine Chaser No. 20 or USS S.C. 20, was an SC-1-class submarine chaser built for the United States Navy during World War I.

SC-17 was a wooden-hulled 110-foot (34 m) submarine chaser built at the New York Navy Yard at Brooklyn, New York. She was commissioned on 18 October 1917 as USS Submarine Chaser No. 20, abbreviated at the time as USS S.C. 20.

S.C. 20 was assigned to the Third Naval District for patrol duties during World War I.

When the U.S. Navy adopted its modern hull number system on 17 July 1920, Submarine Chaser No. 20 was classified as SC-20 and her name was shortened to USS SC-20.

Sometime in 1920, the Navy transferred SC-20 to the United States Department of War for service with the United States Army.
