The second USS Amphitrite—the lead ship in her class of iron-hulled, twin-screw monitors—was laid down, on June 23, 1874, by order of President Ulysses S. Grant's Secretary of Navy George M. Robeson at Wilmington, Delaware, by the Harlan and Hollingsworth yard; launched on 7 June 1883; sponsored by Miss Nellie Benson, the daughter of a Harlan and Hollingsworth official; and commissioned at the Norfolk Navy Yard, Portsmouth, Virginia, on 23 April 1895, Captain William C. Wise in command.

A monitor is a relatively small warship that is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War.
