The USNS Cheyenne (T-AG-174) was a Phoenix-class Miscellaneous Auxiliary ship laid down on May 08, 1945 as SS Middlesex Victory. The ship was launched on June 26, the same year. It was acquired by the U.S. Navy on December 29, 1962, and placed-in-service as USNS Cheyenne (T-AG-174) in February 1963. During its activity, the ship carried a complement of 52 people on board and had acted as a point-to-point cargo carrier that delivered military supplies to Okinawa and Vietnam. The ship was struck from the Naval Register on June 15, 1973, but the ultimate fate is unknown. Between World War II and the late-1970s, the Navy was one of the largest consumers of asbestos products, and this meant that a lot of sailors were constantly being exposed to the deadly fibers. Once they are inhaled, or in some cases ingested, asbestos fibers can become trapped in a layer of tissue known as the mesothelium. Once there, they can stay over a period of 20 to 50 years until an asbestos-related disease presents symptoms that will often cause a victim to go to a doctor to find out what is wrong.
