The Iowa-class battleships, among the most formidable representatives of their ship type globally, were designed to support and safeguard high-speed aircraft carrier formations. The lifting of international restrictions paved the way for the creation of ships with robust protection and formidable armament. USS Iowa took part in numerous World War II operations, including the Battles of the Philippine Sea and Leyte Gulf, and she provided support to UN forces during the Korean War. The battleship is currently moored in the Port of Los Angeles as a museum ship.
