The USS Castine (PG-6) was a United States Navy gunboat launched on May 11, 1892, by Bath Iron Works in Bath, Maine. She was commissioned on October 22, 1894, under Commander Thomas Perry, and served primarily within the Atlantic Fleet. Constructed as a gunboat, Castine measured approximately 200 feet in length, with a beam of around 30 feet, and was armed to fulfill her role in patrol, blockade, and expeditionary duties, although specific dimensions and armament details are not provided in the source. Throughout her active service, Castine undertook extensive deployments. She initially cruised in South American and West Indian waters, calling at ports such as the Azores, Gibraltar, Zanzibar, Mozambique, and Pernambuco, Brazil. She participated in the Spanish–American War, arriving in March 1898 to enforce the blockade against Cuba and support troop movements during the conflict. After the war, she journeyed to East Asia via the Suez Canal, arriving in the Philippines in late 1898, where she operated during the Philippine–American War, assisting with the evacuation of Spanish garrisons and patrolling Chinese waters. Castine was decommissioned briefly in 1901 but was recommissioned in 1903, serving in the South Atlantic, Mediterranean, and Caribbean. She functioned as a submarine tender from 1908 until 1913, during which she was involved in a collision near North Truro, Massachusetts, in 1910, and was subsequently repaired. Her service included operations off Mexico and in the Caribbean, notably in Santo Domingo harbor in 1916. During this incident, heavy waves—likely wind-generated rather than a tsunami—damaged her severely, nearly causing her to capsize amid waves possibly produced by hurricanes active in the region. During World War I, Castine transported troops and supplies to European ports, operating under the Patrol Force at Gibraltar until late 1918. She was awarded the Navy Cross for her hazardous service in waters infested with submarines and mines. Decommissioned in 1919, Castine was sold in 1921 but sank in 1924 following an onboard explosion while en route to be scrapped. Her wreck was identified in 2001, lying at about 105 feet of water, and was later added to the National Register of Historic Places in 2009, marking her as a vessel of maritime historical significance.
