United States Army Air Forces. On 9 June, while the submarine was patrolling on the surface, an enemy plane broke quickly from a low cloud and attacked. As Snapper quickly dove, one bomb struck directly above the hatch instantly killing one crewman and injuring several others, including the commanding officer. As the submarine continued to dive, shells were heard striking her hull. Upon surfacing, it was found that her pressure hull had not been damaged, but a heavy oil slick indicated a puncture of a fuel oil ballast tank. Minor repairs were made. Two wounded enlisted men were transferred to submarine tender at Majuro Atoll on 13 June, and Snapper continued her lifeguard duty until returning to Pearl Harbor on 21 July. On 5 September, Snapper departed Pearl Harbor for her eleventh and final war patrol, conducted in the Bonin Islands area. On 1 October, the submarine encountered two enemy vessels escorted by a small patrol craft. The submarine fired her bow torpedoes at the large target then swung for a "down-the-throat" shot at the smaller vessel. Hits were scored on both vessels resulting in the sinking of the passenger-cargo ship Seian Maru, and the coastal minelayer, Ajiro. Snapper then took up lifeguard station off Iwo Jima until 18 October and terminated her eleventh patrol at Midway on 27 October, before continuing on to Pearl Harbor. End of war and fate Snapper departed Pearl Harbor on 2 November and set sail for overhaul at the Mare Island Navy Yard. Getting underway from Mare Island on 9 March 1945, the submarine arrived at San Diego on 11 March and engaged in local training operations for several months. She transited the Panama Canal on 20 May and arrived at New London, Connecticut, on 27 May where she operated until decommissioned at Boston, Massachusetts, on 17 November 1945. Snapper was struck from the Naval Vessel Register on 30 April 1948 and sold for scrap to the Interstate Metals Corporation of New York City, on 18 May 1948.
