USS SC-255
USS "SC-255, sometimes styled as either Submarine Chaser No. 255 or S.C.-255", was an built for the United States Navy during World War I. Like most members of her class, she was not named and known only by her designation. "SC-255" was built at George Lawley & Sons in Neponset, Massachusetts in 1917. She was commissioned 19 November 1917. On 15 April 1918 "SC-255" left Bermuda in a convoy with 29 other submarine chasers, four U.S. Navy tugs, two French tugs and destroyer tender . Cruiser and armed yacht performed escort duty for the convoy. On 24 April, "SC-255" was  taken under tow for a time by "Bridgeport", and three days later, the convoy reached Ponta Delgada, Azores. At some point in her career, "SC-255" entered dry dock in Malta. It is unclear if "SC-255" remained in commission on 17 July 1920. If she were, she would have received, as part of the new U.S. Navy letter-number scheme, the hull designation of PC-255. "SC-255" was sold on 24 June 1921 to Joseph G. Hitner of Philadelphia. Her ultimate fate is unknown.
