The USS Carbonero (SS/AGSS-337) was a Balao-class submarine constructed for the United States Navy, notable for its diverse service history and technological adaptations. Laid down on December 16, 1943, by the Electric Boat Company in Groton, Connecticut, she was launched on October 19, 1944, and commissioned on February 7, 1945. The vessel's dimensions and specific physical characteristics are not provided in the given source. Initially, Carbonero operated from New London, Connecticut, before serving with the Fleet Sonar School at Key West and conducting exercises in the Canal Zone. She arrived at Pearl Harbor in May 1945 for her first war patrol off Formosa, primarily performing lifeguard duties during aircraft carrier strikes. Her second patrol in the Gulf of Siam involved sinking multiple small Japanese vessels, including schooners, sampans, and junks, marking her active combat role toward the end of World War II. The ceasefire on August 15, 1945, ended her wartime operations, and she returned to the U.S., conducting post-war activities. In the post-war years, Carbonero was assigned to the Submarine Guided Missile Program, functioning as a control vessel for missile guidance tests, including launching Loon and Regulus missiles. Fitted with the Fleet Snorkel modification in 1951, she operated off Southern California and Hawaii. In 1953, further equipment allowed her to guide missiles beyond the firing ship’s range. Her home port shifted to Pearl Harbor in 1957, where she became the flagship of Submarine Division 12 and participated in various operations, including deployments to the Far East, South Pacific, and Arctic cruises. During her service, Carbonero participated in nuclear testing during Operation Dominic in 1962 and was involved in biological testing as part of Project SHAD, deploying Bacillus globigii for research purposes. She returned to a standard attack submarine configuration in 1962 and was decommissioned on December 1, 1970. Her final operational act was as a target for a Mark 48 torpedo test in April 1975. The vessel's notable contributions include her wartime patrols and technological roles in missile testing and nuclear experiments, marking her as a versatile and significant vessel in mid-20th-century naval operations.
