Submarine Command

SS-306 was actually the USS Tang. In her short career, lasting barely over a year, she amassed an unequaled record. Depending on the source, she sank either 24 ships for 93,824 tons or 31 ships in her five patrols, totaling 227,800. The Tang was sunk on 25 October,1944 with the loss of 74 men. Nine men, including her skipper, survived. Tang was sunk by her last torpedo which made a circular run. Picked up by a Japanese destroyer, the men were tortured by survivors of the ships she had sunk in her last action. They were interred at Japanese POW camps until the end of the war.

On at least three occasions the sailors call the Tigershark submarine a "ship". All submariners know that submarines are referred to as "boats".
