The USS Ibex (IX-119) was an Armadillo-class tanker designated an unclassified miscellaneous vessel and commissioned by the U.S. Navy for service in World War II. The ship was laid down under a Maritime Commission contract by California Shipbuilding Corporation in Wilmington, California on 16 October 1943 and launched 15 November 1943. She was placed in commission the same day with Lieutenant Commander John L. Frazer in command. From October 1944 until the end of World War II, the USS Ibex (IX-119) operated with Servron 8, Third Fleet, which supplied the fighting units during the most crucial months of the war. The ship decommissioned at Norfolk, Virginia, on 28 June 1946, was returned to the Maritime Commission on 30 June. In 1948 she was sold to T. J. Stevenson Company, Inc. and renamed Helen Stevenson. Because of the extensive use of asbestos on ships, Navy veterans make up approximately 3,000 mesothelioma cases diagnosed each year. Serving on the USS Ibex (IX-119) or assisting in the construction, repair, renovation, or demolition, is consequently a risk for contracting asbestos-related diseases.
