The USS S-42 (SS-153) was the first member in the third group of S-class submarines of the United States Navy. Her keel was laid down on 16 December 1920 by the Bethlehem Shipbuilding Corporation's Fore River Shipyard in Quincy, Massachusetts. She was launched on 30 April 1923 sponsored by Mrs. Henry A. Hutchins, Jr., and commissioned on 20 November 1924, Lieutenant John Brown in command. The submarine became permanently inactive in 1945 and was sold for scrapping in 1946. Asbestosis is a type of pulmonary fibrosis, or lung scarring, specifically caused by inhaling asbestos fibers. Asbestosis can be difficult to diagnose since many other respiratory diseases such as COPD, idiopathic pulmonary fibrosis, interstitial pneumonitis, and constrictive bronchiolitis have similar symptoms. Navy veterans diagnosed with asbestosis as a result of exposure to asbestos during their service are entitled to compensation.
