USS Pampanito (SS 383) was built by the Portsmouth Naval Shipyard, Portsmouth, New Hampshire, and was commissioned on November 6, 1943. She is a fleet type submarine of the Balao class. Her deck is of teakwood and her exterior is painted haze gray and black. She is a pre-snorkle type submarine, operating underwater on batteries, and powered by four engines with a diesel system delivering 6,400 horsepower.
The crew consisted of 75 officers and enlisted men berthed in every available space, including, over the torpedo tubes. The submarine escaped the guppying process (the complete exterior and interior alteration that most World War II boats experienced after the war) and retains her original design and fittings. The boat is in excellent condition and is now open to the public as a museum ship at Pier 45 at Fisherman's Wharf in San Francisco. 
Role of the Submarine in World War II
In the conflict against Japan in World War II, the role and importance of the submarine forces of the United States cannot be overestimated. American sub marines sank more than 600,000 tons of enemy warships and more than 5,000,000 tons of merchant shipping, thus destroying much of Japan's ocean commerce. This was accomplished by a force that never numbered more than two percent of naval personnel engaged in the war. The American submarine war against Japan created a blockade that denied her the oil, iron ore, food, and other raw materials she needed to continue to fight. By 1945 this submarine war made it almost impossible for any Japanese ship to sail the ocean. Without this commerce and the raw materials it supplied to her war effort, Japan found it impossible to continue the war outside of the homeland.
