The USS Hannibal (AG-1) was originally launched as the Joseph Holland, a 1,785 gross register ton (GRT) steamer built in Sunderland, England, by J. Blumer & Company. Laid down at the North Dock yard (hull 143) for F. S. Holland of London, she was completed in April 1898. The U.S. Navy purchased her on April 16, 1898, shortly before her commissioning on June 7, 1898, and renamed her Hannibal. She served prominently in various conflicts, notably participating in the Spanish–American War, where she took part in the Puerto Rico Campaign, including the bombardment of Spanish positions at Fajardo. Her service in this conflict earned her the Spanish Campaign Medal, with officers and crew receiving the Spanish Campaign badge for 1898. Following her wartime service, Hannibal operated as a collier along the Atlantic coast from 1898 to 1908, providing logistical support. In 1908, after an overhaul, she continued her role in collier service based in New England until her decommissioning in August 1911. She was recommissioned later that year and assigned to hydrographic survey duties in the Caribbean and Central America, supporting the planned Panama Canal opening. Her hydrographic work extended through the 1910s, with surveys conducted in Panama, Nicaragua, Honduras, and Cuba. During World War I, Hannibal operated with the Atlantic Fleet’s Patrol Force, later serving as a tender to submarine chasers in Plymouth, England, and escorting sub-chasers across the Atlantic. After the war, she resumed survey operations until 1930, covering waters near Trinidad, Venezuela, Costa Rica, and the Panama Canal Zone. In 1933, she and Gannet pioneered the collection of dynamic sounding data, integrating depth and oceanographic measurements. Remaining in service until 1940, Hannibal supported the U.S. Navy Hydrographic Office for 28 years. During World War II, she operated out of Norfolk, Virginia, in the Chesapeake Bay degaussing range. She was decommissioned on August 20, 1944, and sunk as a bombing target in March 1945. Her wreck served as a target for 21 years, and in 1966, the Navy sank another vessel nearby, maintaining the site as a live-fire target range still referred to as Hannibal.
