}} | USS SC-23, until July 1920 known as USS Submarine Chaser No. 23 or USS S.C. 23, was an SC-1-class submarine chaser built for the United States Navy during World War I. SC-23 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 16 October 1917 as USS Submarine Chaser No. 23, abbreviated at the time as USS S.C. 23. During World War I, S.C. 23 served in the {{USS|Patterson|DD-36|6}} Group of submarine chasers. {{expand section|SC-23{{'}}s operational history from October 1917 to 1920|date=February 2011}}When the U.S. Navy adopted its modern hull number system on 17 July 1920, Submarine Chaser No. 23 was classified as SC-23 and her name was shortened to USS SC-23. Sometime in 1920, SC-23 was destroyed by fire. References - {{DANFS|http://www.history.navy.mil/danfs/sc1/sc-1-sc-100v1.htm}}
