With 6 battle stars and a Navy Unit Commendation, the submarine was laid down in 1941, as most of the Gato-class ships. It successfully completed 4 war patrols. Because it was built during a time when tremendous amounts of asbestos were employed by shipyards, the carcinogen was present on the USS Haddo in the form of wall insulation, but also in other machinery and equipment. Consequently, we strongly advise veterans who serve on this submarine to pay close attention to their health and seek immediate medical attention if they notice worrisome symptoms such as shortness of breath, chest pain or fatigue. In 1958, the USS Haddo was struck from the Naval Vessel Register and subsequently sold for scrapping.
