Seawolf Park is a memorial to USS Seawolf (SS-197), a United States Navy Sargo-class submarine mistakenly sunk by U.S. Navy forces in 1944 during World War II. It is located on Pelican Island (29°20′03″N 94°46′45″W / 29.33417°N 94.77917°W), just north of Galveston, Texas, in the United States.
Seawolf park is unique in that it has a submarine, and the remains of a merchant ship, and a destroyer escort designed to conduct antisubmarine warfare -- the hunter, hunted, and the protector -- all in one museum area. It is the home of two preserved U.S. Navy ships, the Gato-class submarine USS Cavalla (SS-244) and the Edsall-class destroyer escort USS Stewart (DE-238), and the remains of the World War I tanker S.S. Selma, the largest concrete ship constructed, can be seen northwest of the park's fishing pier at 29°20′40″N 94°47′10″W / 29.34444°N 94.78611°W . Also preserved at the park is the conning tower of the Balao-class submarine USS Carp (SS-338) and the sail of the Sturgeon-class nuclear attack submarine USS Tautog (SSN-639).
