Built in 1942 by the Electric Boat Company, the USS Flasher took part in World War II, having earned 6 battle stars and a Presidential Unit Citation. The conning tower can now be seen at the National Submarine Memorial, in Groton, Connecticut. Although it enjoyed a successful career, the submarine was insulated with asbestos, a carcinogenic naturally occurring mineral whose inhalation can lead to diseases such as lung cancer and mesothelioma. Thus, we strongly encourage veterans who served on the USS Flasher to undergo periodical medical examinations in order to make sure their lungs have not been affected. In 1946, it was decommissioned and later sold for scrapping.
