USS Pampanito (SS-383)

USS Pampanito is a World War II Balao class Fleet submarine museum and memorial. Pampanito made six patrols in the Pacific during World War II during which she sank six Japanese ships and damaged four others. Her biggest day came on September 12, 1944, when she and two other submarines surprised an 11-ship convoy and sank seven vessels. Later, Pampanito rescued 73 Allied prisoners of war who had been carried aboard the enemy transports.

An in depth tour of the Pampanito is available on the San Franciscio Maritime National Park Association's website. The Pampanito is located at Pier 45, Fisherman's Wharf and is normally open to the public seven days a week. Pampanito is a National Historic Landmark.
