Built by the Cramp Shipbuilding Company in 1942, as most Balao-class submarines, the USS Dragonet completed 3 war patrols, out of which 2 were successful. Therefore, it earned 2 battle stars for World War II activity. It began cruising in 1944 under the command of Commander Jack Hayden Lewis. Asbestos, a highly carcinogenic mineral with numerous convenient properties such as fire resistance, was very prevalent in shipbuilding during the last century. The USS Dragonet also had asbestos materials onboard, including gaskets, boilers, valves and wall insulation. Therefore, veterans who served on this submarine should pay close attention to their health and undergo regular medical examinations to ensure their lungs have not been affected by asbestos exposure. The vessel was decommissioned in 1946 and eventually sunk by explosive test in Chesapeake Bay.
