Vessels built during 1930-1970 contained asbestos, a very poisonous substance, which could be found in their components like turbines, valves, pumps and even the engine and boilers rooms. Because of the poor ventilation existed on board, people who worked on these ships inhaled the poisoned air during their service and are likely to suffer now from mesothelioma, a type of lung cancer. One of those ships is USS John F. Kennedy, a John F. Kennedy-class Aircraft Carrier, the only one built in its class, with the hull number CV-67. The ship was commissioned in 1968, carried almost 3,300 men on board and measured 1,052 feet. Its missions were held in the Middle East and the Mediterranean and Indian Ocean before being decommissioned in 2007 after 39 years of service. The companies that provided the contaminated materials were aware of the high risk of exposure to asbestos, but decide to keep silent. This is why they should sue those companies in order to receive some compensation.
