  1. Monitor

    A monitor was the class of relatively small warship which was neither fast nor strongly armoured but carried disproportionately large guns. They were used by some navies from the 1860s until the end of World War II, and saw their final use by the United States Navy during the Vietnam War. The monitors of the 19th century were turreted ironclad warships inspired by the original USS Monitor; as well as coastal ships which closely followed her design. The term "monitor" also encompassed more flexible breastwork monitors, and was sometimes used as a generic term for any turreted ship. The term "monitor" also represents the strongest of riverine warcraft, known as river monitors. In the early 20th century, the term "monitor" was revived for shallow-draft armoured shore bombardment vessels, particularly those of the British Royal Navy: the Lord Clive class monitors carried guns firing heavier shells than any other warship ever has, seeing action against German targets during World War I. The Lord Clive vessels were scrapped in the 1920s.

Dictionary of Nautical Terms

  1. monitor

    A very shallow, semi-submerged, heavily-armoured steamer, carrying on her open deck either one or two plated revolving turrets, each containing either one or two enormous guns: originally designed by Ericson in the United States during the recent war, to combine the maximum of gun power with the minimum of exposure; they have been very formidable in sheltered and intricate waters, but it remains yet to be shown that they would be effective on the open sea.
