USS Charleston, the third cruiser of the St. Louis class, served in the Far East until 1910. In 1916 and 1917, she operated as a floating base for submarines. During World War I, the ship was engaged in escorting troop convoys and conducting training exercises for reservists. From 1920 to 1923, the ship served as the floating headquarters for the flagship destroyer of the Pacific Squadron. In 1923, the cruiser was stricken off the Navys register and subsequently sold in 1930. The ships hull was repurposed for use as a breakwater in British Columbia. In 1961, it was partially sunk and later towed to Kelsey Bay on Vancouver Island, where it continued its role as a breakwater.
