USS Point Defiance (LSD-31) (Non-retention)

Classified as a Landing Ship Dock by the U.S. Navy, USS Point Defiance is named after a park in Tacoma, Washington, and is the fourth ship of the eight-ship Thomaston- class. Point Defiance was constructed by the Ingalls Shipbuilding Corp., Pascagoula, Mississippi, and commissioned on March 31, 1955.  Following shakedown in the Gulf of Mexico, the ship steamed to Long Beach, California, to join the Navy’s Pacific Fleet, Amphibious Squadron 7.  Point Defiance was very active in the Pacific in the years leading to and during the Vietnam War.  The ship completed its last tour of duty in Vietnamese waters in 1973.  A notable highlight in the ship’s career occurred in 1963 when it transported the bathyscaphe Trieste (a deep-diving research submarine) from San Diego through the Panama Canal to Boston for deep search operations into the cause of the loss of the nuclear submarine Thresher.  Decommissioned on September 30, 1983, Point Defiance was stricken from the Naval Register on February 24, 1992. On September 29, 1995, the ship was sold for scrapping; however, the Navy repossessed the ship from the scrap company in July 1997. Since then, the ship has been laid up in the Suisun Bay Reserve Fleet, pending final disposal.  USS Point Defiance earned 10 campaign stars for its Vietnam War service
