With 10 battle stars and a Presidential Unit Citation for its remarkable performance during the first three war patrols, the USS Greenling was commissioned in 1942 and had Lieutenant Comdr. H. C. Bruton in command. Despite the successful activity of the submarine, the people who were serving on it were in great danger due to the asbestos wall insulation present on it. Exposure to this carcinogen occurs by inhaling or ingesting airborne fibers, which subsequently embed themselves in the lining of various organs in the body. The vessel was decommissioned in 1946 and sold for scrapping in 1960.
