USS CARBONERO SS 337

USS Carbonero (SS-337) was a Balao-class submarine commissioned by the United States Navy in February 1945, near the end of World War II. Although she arrived too late to see combat in the war, Carbonero participated in postwar operations, including the notable Operation Crossroads atomic bomb tests at Bikini Atoll in 1946. Throughout the Cold War, she served primarily as a training and research submarine, supporting the development of submarine tactics and new weaponry. After decades of distinguished service, USS Carbonero was decommissioned in 1970 and later sunk as a target in 1975.
