The USS Nightingale (MSC(O)-50/AMS-50/YMS-290) was a YMS-1-class minesweeper of the YMS-135 subclass, designed for the hazardous task of removing naval mines from water to ensure safe passage for ships. Built by the Associated Shipbuilding Company in Seattle, Washington, she was launched on 27 February 1943 and commissioned on 17 July 1943. She was the fifth vessel to bear the name Nightingale in the U.S. Navy. Constructed as YMS-290, the vessel was a relatively small, agile minesweeper typical of its class, intended for mine clearance operations during World War II. After shakedown and training in Puget Sound, she sailed for the western Pacific via Pearl Harbor. Her wartime service was concentrated in the Pacific theater, where she participated in the Gilbert Islands campaign from 13 November to 8 December 1943. Following this, she continued minesweeping operations until the end of the war, contributing to the Allied efforts to clear minefields in support of amphibious landings and naval operations. After hostilities ceased, YMS-290 was assigned to minesweeping duties in the Kobe-Fukuoka region of Japan. Post-war, she returned to the United States, arriving in Boston, Massachusetts, where she was assigned as a Naval Reserve Training ship in the 1st Naval District. On 1 September 1947, she was renamed Nightingale and reclassified as AMS-50. She served as a training vessel until March 1950, when she was decommissioned at Green Cove Springs, Florida. Recommissioned in February 1951, Nightingale operated with the Atlantic Fleet's Mine Force, based out of Charleston, South Carolina. Her operations extended along the U.S. East Coast from Yorktown, Virginia, to Panama City, Florida. For a period starting 1 January 1955, her home port shifted temporarily to Panama City while supporting the Navy’s Mine Defense Laboratory. She was re-designated MSC(O)-50 on 7 February 1955 and later returned to Charleston. The vessel remained active until she was decommissioned again on 1 November 1959, struck from the Navy List, and sold for scrap, ending her service career.
