Commissioned in 1943 with Lieutenant Commander Henry G. Munson in command, the submarine was built by Portsmouth Naval Shipyard in Maine. With 7 war patrols successfully completed, the USS Crevalle received a Navy Unit Commendation and 4 battle stars. It also sunk a total of 51,814 tons of enemy shipping. Despite the remarkable performance of this submarine, there was a danger lurking onboard - asbestos exposure, which can cause a wide range of debilitating diseases, such as lung cancer and mesothelioma. Therefore, we highly recommend everyone who was present on the USS Crevalle to keep a close eye on their health by undergoing periodical medical examinations to make sure their lungs have not been affected by asbestos fibers. In 1962, the submarine was decommissioned and eventually sold for scrap 3 years later.
