USS Monadnock (ACM-10) was a coastal minelayer in the U.S. Navy, the third vessel named after Mount Monadnock, a solitary mountain (monadnock) of more than 3,100 feet in southern New Hampshire close to the border of Massachusetts. The ship was built as the cargo vessel Cavalier for the Philadelphia and Norfolk Steamship Company by Pusey and Jones Corporation, Wilmington, Delaware in 1938. The Navy purchased the ship 9 June 1941 for wartime use. After decommissioning the ship was sold in June 1947 for commercial use then sold to a Panamanian company in 1949 to be renamed Karukara. In 1952 the ship became Monte de la Esperanza for a company in Bilbao, Spain transporting bananas to the United Kingdom from the Canary Islands for more than 20 years. She was later sold to the Marine Institute of Spain for operation as a hospital ship for more than 10 years serving the fishing fleet of the Canary Islands as Esperanza del Mar until becoming an artificial reef off Spain in 2000.
