Operational history

Monocacy was built in 1905 by the Maryland Steel Co. of Sparrow's Point, Maryland. She was acquired by the Navy on 27 July 1917 from the Philadelphia and Reading Railway Co., in Philadelphia, Pennsylvania, and placed in service at the Philadelphia Navy Yard on 25 September 1917, designated SP-1116. She was commissioned 10 November 1917 as USS Genesee (Fleet Tug No. 55).

Genesee sailed from Philadelphia 20 November 1917 and, after joining a convoy at New London, reached Queenstown, Ireland, 27 January 1918. Until the end of World War I she operated in the Bremerhaven-Queenstown areas patrolling, towing, and serving as standby for deep sea rescue work. After towing USS Luella from Queenstown to Brest, Genesee arrived Ponta Delgada, Portugal, 31 December 1918 and served as a tug at that port until 1 April 1919 when she sailed for Brest. She provided tug services and aid to stricken ships and finally got underway 30 September for a 7-month tour of duty off Spalato, Dalmatia, and in Castella Bay. On 17 July 1920 Genesee was designated AT-55.

Next assigned to the Far East, Genesee arrived Cavite, Luzon, 7 September 1920 for permanent duty on the Asiatic Station. She spent the summer of 1921 with the fleet at Chefoo, China, and returned to Cavite 19 September. Subsequently she operated as a tug, a ferry, and a target tow in the Philippines until she was scuttled at Corregidor 5 May 1942 to avoid capture.

Subsequently raised by the Japanese, she was designated Patrol Boat No. 107. On 5 November 1944, American F6F Hellcats from Task Group 38.3 sank Patrol Boat No. 107 off Lubang Island (14°23′N 120°25′E / 14.383°N 120.417°E / 14.383; 120.417).^[1]
