Sponsored by Mrs. Jane Gawne, wife of Captain James Gawne, the USS Bowfin was a Balao-class submarine built in 1942 by Portsmouth Navy Yard. The submarine sunk a remarkable number of enemy vessels, including the passenger-cargo ship Kirishima Maru, the cargo ship Tsukikawa Maru, the passenger-cargo ship Tsushima Maru, as well as the cargo ship Shoyu Maru. Today, it can be seen at the USS Bowfin Submarine Museum & Park in Pearl Harbor, on the island of Oahu, Hawaii. Furthermore, in 1986, the submarine was declared a National Historic Landmark. However, despite the successful career the USS Bowfin enjoyed, there was a danger onboard - asbestos exposure, which can cause a wide range of lung disease. Therefore, we strongly advise veterans who served on it to pay close attention to their health and prevent the occurrence of such illnesses by undergoing regular medical examinations.
