Monadnock (ACM-14) was originally built as an M1 mine planter[1] for the U.S. Army Coast Artillery Corps, Mine Planter Service as USAMP Major Samuel Ringgold (MP 11)[2] by the Marietta Manufacturing Co., Point Pleasant, WV and delivered to the Army December 1942.[3] The ship was named for Samuel Ringgold (1796–1846), an officer noted as the "Father of Modern Artillery" that fell in the Mexican-American War.
The mine planter was transferred to the U.S. Navy in March 1951 to become an Auxiliary Minelayer (ACM / MMA) under naval designation. She was then berthed at Boston as a unit of the Atlantic Reserve Fleet. While in the Reserve Fleet, she was redesignated MMA-14,  7 February 1955, and named Monadnock, 1 May 1955; the second ACM to bear this name.[4] The ship was never commissioned and thus never bore the "USS" prefix. Monadnock was struck from the Navy list on 1 July 1960 and sold to commercial interests. In commercial service the ship was named Thiti, Amazonia and eventually Dear operating into the 1980s under Italian registry.[2]
