USS Razorback Submarine

USS Razorback, a Balao-class submarine of the Sandlance variant, was built at the Portsmouth Naval Shipyard in Kittery, Maine. Her keel was laid on 09 September, 1943. Razorback was constructed in Drydock #1 at the shipyard, and she was launched, along with two sister ships (USS Redfish (SS 395) and USS Ronquil (SS 396)) on 27 January, 1944. USS Scabbardfish (SS 397) was also launched at the shipyard that day. This was the largest single-day launch of US submarines ever. Razorback conducted five combat patrols during World War II, sinking Japanese vessels, capturing Japanese POWs and rescuing American pilots who had been shot down. At the end of WWII, she was one of only 12 submarines selected to be present in Tokyo Bay when the Japanese surrender was signed.
