The USS Olympia (C-6/CA-15/CL-15/IX-40) is a historic protected cruiser built for the United States Navy, commissioned in 1895 and serving until 1922. She measures approximately 344 feet in length with a beam of 53 feet and a draft of around 21.5 feet. Displacing about 5,865 long tons at standard load, Olympia was constructed with a steel hull and powered by twin vertical triple-expansion engines, which produced up to 13,500 indicated horsepower and propelled her to a top speed of over 21 knots during trials. Her armament originally included four 8-inch/35 caliber guns in twin turrets, supported by ten 5-inch/40 caliber guns, fourteen 6-pounder guns, and two 1-pounder guns, along with torpedo tubes. Built by Union Iron Works in San Francisco, her keel was laid in 1891, and she was launched in 1892. Despite delays, she achieved impressive speeds in trials, surpassing the contract requirements. Her armor scheme included a 5-inch thick conning tower, a 2-inch armored deck, and protective plating over her main guns and barbettes, emphasizing her role as a protected cruiser. Olympia gained fame as the flagship of Commodore George Dewey during the Battle of Manila Bay in 1898, where she led the U.S. fleet to a decisive victory over Spanish forces. This engagement marked her as a symbol of American naval power and imperial ambition. After the war, she returned to the U.S., participated in various training, patrol, and diplomatic missions—including supporting the 1919 Russian Civil War intervention—and carried the remains of the Unknown Soldier from France in 1921. Decommissioned in 1922, Olympia became a museum ship in Philadelphia and was designated a National Historic Landmark in 1966. As the oldest steel U.S. warship afloat, she has undergone extensive preservation efforts. Despite deterioration and funding challenges, ongoing repairs aim to sustain her as a symbol of naval history and American maritime heritage.
