Vessels built during 1930-1970 contained asbestos, a very hazardous substance, which could be found in their components like turbines, valves, pumps, and even the engine, boilers rooms, mess halls, and sleeping quarters. Because of the poor ventilation that existed on board, the navy personnel who worked on these ships inhaled the toxic air during their service and are likely to suffer now from mesothelioma, a type of lung cancer.
One of those ships is the USS Kearsarge (CV-33), an Essex-class aircraft carrier, with the hull number CV-33. The ship was commissioned in 1946, carried almost 3,500 men on board and almost 100 aircraft. Its operations were held in Asia before being decommissioned in 1970 after 24 years, which led to the receiving of two battle stars for the results obtained in the Korean War.
