The USS Spiegel Grove (LSD-32) was a Thomaston-class dock landing ship constructed for the United States Navy, serving from her commissioning in 1956 until her decommissioning in 1989. Built by Ingalls Shipbuilding Corp. in Pascagoula, Mississippi, she was laid down on September 7, 1954, launched on November 10, 1955, and officially commissioned on June 8, 1956. The vessel measured approximately 510 feet in length and 84 feet in width, with her hull designed to facilitate amphibious operations, including transporting and launching landing craft and vehicles. Throughout her active years, Spiegel Grove participated extensively in amphibious exercises along the east coast of the United States and in the Caribbean, supporting operations such as "Solant Amity" tours to Africa and the Mediterranean, as well as goodwill missions. She was involved in notable operations, including the evacuation of American citizens from Cyprus in 1974 and Lebanon in 1976. The ship also took part in international exercises like "Operation Steel Pike I" off Spain in 1964 and a midshipman cruise to England and Denmark in 1970. Her service extended to supporting space missions, such as Malcolm Scott Carpenter's Mercury-Atlas 7. Spiegel Grove earned recognition for her service, notably winning the Marjorie Sterrett Battleship Fund Award in 1983. Her operational history included deployments with the 6th Fleet and participation in various amphibious and disaster relief missions until her decommissioning on October 2, 1989. After decommissioning, she was transferred to the Maritime Administration and later to the state of Florida with the plan to create an artificial reef. In 2002, Spiegel Grove was intentionally sunk off Key Largo as an artificial reef and dive site in the Florida Keys National Marine Sanctuary. The sinking was initially unsuccessful, causing her to settle upside-down, but she was later righted with additional effort and now rests on the ocean floor. Measuring about 160 meters long, she has become one of the most popular and extensive artificial reefs, attracting thousands of divers annually. The wreck's complex interior and depth make it a challenging site, requiring advanced diving certification. Her significance lies both in her service history and as a prominent site promoting marine recreation and conservation.
