The USS Agile (MSO-421) was an Agile-class non-magnetic minesweeper built for the United States Navy, primarily tasked with detecting and removing naval mines to ensure safe passage for other vessels. Laid down on 22 February 1954 in Stamford, Connecticut, by Luders Marine Construction Co., she was initially designated AM-421 and was reclassified as MSO-421 on 7 February 1955. The vessel was launched on 19 November 1955, sponsored by Mrs. Alice Donohue, and commissioned at the New York Naval Shipyard on 21 June 1956. Constructed as a non-magnetic ocean minesweeper, Agile was designed to operate in challenging environments where magnetic mines posed significant threats. After fitting out in New York, she departed for her home port of Charleston, South Carolina, on 13 July 1956. Following shakedown training at Guantanamo Bay, Cuba, and post-shakedown availability at Charleston Naval Shipyard, Agile embarked on her first deployment to the Mediterranean in early 1957. During this deployment, she participated in amphibious exercises and port visits across Greece, France, and other Mediterranean locations, notably during the Jordan crisis of April 1957. Throughout her service, Agile undertook multiple Mediterranean deployments, NATO exercises, and local operations along the North American coast. She participated in various tests, including special mine defense tests with the Mine Defense Laboratory in Florida, and served as a school ship for the Mine Warfare School. Her operational activities included routine minesweeping, port visits, joint exercises, and testing missions, demonstrating her versatility and importance in naval mine countermeasure operations. Agile's last Mediterranean cruise occurred in 1964, after which she primarily operated near North America, conducting local exercises, training, and test support. She was decommissioned on 28 July 1972 and placed with the Atlantic Reserve Fleet at Norfolk. Her name was struck from the Naval Vessel Register in September 1977, and she was sold for scrapping in February 1980. Agile's service highlights her contribution to U.S. naval mine countermeasures during the Cold War era, emphasizing her role in maintaining naval safety and operational readiness.
