The SS Jeremiah O’Brien is a Liberty-class ship that was built in the United States for World War II service. It is one of the only three Liberty Ships that are still operational. The ship was built in June 1943 by the New England Shipbuilding Corporation in South Portland, Maine in 56 days, and sent into the European Theatre of Operations. The SS Jeremiah O’Brien was one of the nearly 7,000 ships that were used during Operation Neptune, often referred to as D-Day that started in June 1944, and also one of the few survivors of that operation. After that, the ship moved to the Pacific Theatre of Operations, where it was in service for 16 months in the South Pacific and the Indian Ocean. Until the 1980s, asbestos was used extensively on products used to build ships. The combination of exposure and poor ventilation created a high risk of developing asbestos-related diseases among shipyard workers and Navy veterans. Individuals who believe they have been exposed to asbestos should advise their doctors when discussing their symptoms. Typically doctors will initially diagnose asbestos-related pulmonary conditions using imaging equipment.
