Shark-II Patch       The 6th USS Shark, SS-314, a submarine, and designated as Shark II being the second submarine to be so named during World War II, went though her shake-down off of the coast of New London, CT; then was deployed through the Panama Canal to Pearl Harbor, Hawaii, where she arrived on April 24, 1944, for final training.

      Shark II's first patrol began on May 16, where she joined the USS Pintado (SS-387) and the USS Pilotfish (SS-386) to begin a coordinated attack in the Marianna Islands. Early on the morning of 2 June, 1944, Shark submerged ahead of an enemy convoy and fired a spread of torpedoes at a Japanese tanker. Although all missed the original target, the torpedoes continued on to hit and sink another enemy vessel, the 4,700-ton cargo ship, Chiyo Maru No. 2. After evading an ensuing depth charge attack, the submarine continued her patrol and during this patrol she sank four Japanese ships in an excess of 23,000 tons, while successfully evading Japanese counter-attacks. She sailed to Midway Island and arrived on June 17, for refit and reload.

      Shark II's second patrol began on July 10, 1944, into the Volcano and Bonin Islands. After suffering frustrating attacks, but successful evasions, she was assigned to take a life-guard station off of the coast of Iwo Jima on August 1. On August 4, she rescued two airmen from a torpedo bomber from the USS Lexington (CV-16). She terminated her life-guard duties and after a brief stop at Midway Island she arrived at Pearl Harbor on August, 29.
      Shark II's third patrol took her into the vicinity of Luzon Strait to participate in coordinated attacks with the USS Seadragon (SS-194) and the USS Blackfish (SS-221). Her last message was to the Seadragon on October 24, anticipating an attack on a Japanese freighter. She was never heard from again and on November 27, 1944, she was presumed lost.
      A Japanese report of antisubmarine attacks, now available, records an attack on a submarine by the Japanese destroyer Harukaze in the Luzon Strait on October 24, 1944, by depth charge; almost certainly the demise of the Shark-II.
      The USS Shark (SS-314) received one battle star for World War II service. As she was lost with all souls onboard she is considered to be on Eternal Patrol. Although she is not on the active list of ships she has never been decommissioned.
