A monitor is a class of relatively small warship that is lightly armoured, often provided with disproportionately large guns, and originally designed for coastal warfare. The term "monitor" grew to include breastwork monitors, the largest class of riverine warcraft known as river monitors, and was sometimes used as a generic term for any turreted ship. In the early 20th century, the term "monitor" included shallow-draft armoured shore bombardment vessels, particularly those of the Royal Navy: the Lord Clive-class monitors carried guns that fired the heaviest shells ever used at sea and saw action against German targets during World War I. Two small Royal Navy monitors from the First World War, Erebus and Terror survived to fight in the Second World War. When the requirement for shore support and strong shallow-water coastal defence returned, new monitors and variants such as coastal defence ships were built (e.g. the British Roberts-class monitors). Allied monitors saw service in the Mediterranean in support of the British Eighth Army's desert and Italian campaigns. They were part of the offshore bombardment for the Invasion of Normandy in 1944. They were also used to clear the German-mined River Scheldt by the British to utilize the port of Antwerp. The German, Yugoslav, Croatian, Romanian, Hungarian and Czech armed forces operated river monitors that saw combat during World War II. [1] [2] [3] [4]
See also List of ships of World War II, which contains major military vessels of the war, arranged alphabetically and by type. The list includes armed vessels that served during the war and in the immediate aftermath, inclusive of localized ongoing combat operations, garrison surrenders, post-surrender occupation, colony re-occupation, troop and prisoner repatriation, to the end of 1945. For smaller vessels, see also list of World War II ships of less than 1000 tons. Some uncompleted Axis ships are included, out of historic interest. Ships are designated to the country under which they operated for the longest period of the Second World War, regardless of where they were built or previous service history.

The Illustrious class was a class of aircraft carrier of the Royal Navy that included some of the most important British warships in the Second World War. They were laid down in the late 1930s as part of the rearmament of British forces in response to the emerging threats of Nazi Germany, Fascist Italy and Imperial Japan.
The Derzky or Bespokoiny-class destroyers was a class of destroyers built for the Imperial Russian Navy just before World War I. Nine ships were built for the Black Sea Fleet. These ships were a derivative of the Novik, but were slightly smaller. These ships were popular with the Russians and effective particularly in the Black Sea, where the Ottoman Navy had no similar ships.
The Orfey-class destroyers were built for the Baltic Fleet of the Imperial Russian Navy. They were modified versions of the earlier destroyer Novik and the Derzky-class destroyers. These ships were larger, had triple torpedo tubes and an extra 102 mm (4 in) gun. One ship, Engels, was fitted with a 305 mm (12 in) recoilless rifle for testing in 1934. Fourteen ships were completed in 1914–1917 and fought in World War I and during the Allied intervention in the Russian Civil War. The survivors fought in World War II.
The Izyaslav class were a class of destroyers built for the Baltic Fleet of the Imperial Russian Navy. They were modified versions of the Orfey class built in Russia with the assistance of the French company Augustin Normand. These ships fought in World War I, the Russian Civil War, the Estonian War of Independence, and World War II.
The Highflyer-class cruisers were a group of three second-class protected cruisers built for the Royal Navy in the late 1890s.
HMS Velox (D34) was a V-class destroyer built in 1918. She served in the last year of the First World War and was engaged in the Second Ostend Raid. During the interwar period she underwent a refit and continued serving during the Second World War as a long range convoy escort in the battle of the Atlantic. Post-war Velox was broken up in the reduction of the fleet. Sailors of the ship took part in the Royal Navy mutiny of 1919.
HMS Winchelsea (D46) was an Admiralty W-class destroyer of the Royal Navy, ordered 9 December 1916 from J. Samuel White at Cowes during the 1916–17 Build Programme.
The first HMS Whirlwind was a W-class destroyer of the British Royal Navy that saw service during World War I and World War II.
HMS Walpole (D41) was a W-class destroyer of the Royal Navy.
The flight-deck cruiser was a proposed type of aircraft cruiser,, designed by the United States Navy during the Interwar period. Several designs were proposed for the type, but none was approved for construction. The final design was developed just before World War II, and the entry of the United States into the war saw the project come to an end.
HMS Wren (D88/I88) was an Admiralty modified W class destroyer built for the Royal Navy. She was ordered in April 1918 from Yarrow Shipbuilders Limited under the 13th Order for Destroyers of the Emergency War Program of 1918–19. She was the third Royal Navy ship to carry the name, which was introduced in 1653.
The Yamashio Maru class consisted of a pair of auxiliary escort carriers operated by the Imperial Japanese Army during World War II. They were converted from tankers. Only the name ship was completed during the war and she was sunk by American aircraft before she could be used.
HMS Winchester was an Admiralty W-class destroyer of the Royal Navy. She saw service in the First and Second World Wars.
The Giuseppe Sirtori class consisted of four destroyers built for the Italian Regia Marina during World War I. All four ships saw action during the war, survived the post-war reduction in Italian naval strength, and were lost during World War II.
