The keel of the USS Tuna was laid down in 1939 by Mare Island Naval Shipyard. It earned 7 battle stars for World War II service and was under the command of Lieutenant Commander J.J. Crane. However, because of the year it was built in, the submarine may have contained asbestos wall insulation, which put the lives of those serving on it in great danger. By inhaling or ingesting asbestos fibers, one can develop a debilitating illness such as mesothelioma several decades later. In 1946, the submarine was decommissioned and was later used as a target for Operation Crossroads atomic bomb test. Eventually, it was scuttled off Southern California.
