HMS Erebus was a First World War monitor launched on 19 June 1916 and which served in both world wars. She and her sister ship Terror are known as the Erebus class. They were named after the two bomb vessels sent to investigate the Northwest Passage as part of Franklin's lost expedition (1845–1848), in which all 129 members eventually perished.
The M29 class comprised five monitors of the Royal Navy, all built and launched during 1915.
HMS Raglan was a First World War Royal Navy Abercrombie-class monitor, which was sunk during the Battle of Imbros in January 1918.
HMS Gorgon and her sister ship Glatton were two monitors originally built as coastal defence ships for the Royal Norwegian Navy, as HNoMS Nidaros and Bjørgvin respectively, by Armstrong Whitworth at Elswick. She was purchased from Norway at the beginning of the First World War, but was not completed until 1918 although she had been launched over three years earlier. She engaged targets in Occupied Flanders for the last several months of the war and fired the last shots of the war against such targets on 15 October 1918. She was used as a target ship after several attempts to sell her had fallen through before being sold for scrap in 1928.
The Abercrombie class of monitors served in the Royal Navy during the First World War.
The Erebus class of warships was a class of 20th century Royal Navy monitors armed with a main battery of two 15-inch /42 Mk 1 guns in a single turret. It consisted of two vessels, Erebus and Terror, named after the two ships lost in the Franklin Expedition. Both were launched in 1916 and saw active service in World War I off the Belgian coast. After being placed in reserve between the wars, they served in World War II, with Terror being lost in 1941 and Erebus surviving to be scrapped in 1946.
The Lord Clive-class monitor, sometimes referred to as the General Wolfe class, were ships designed for shore bombardment and were constructed for the Royal Navy during the First World War.
The Marshal Ney class was a class of monitor built for the Royal Navy during the First World War.
The Roberts class of monitors of the Royal Navy consisted of two heavily gunned vessels built during the Second World War. They were the Roberts, completed in 1941, and Abercrombie, completed in 1943.
HMS Marshal Ney was the lead ship of her class of two monitors built for the Royal Navy during the First World War. Laid down as M13, she was renamed after the French field marshal of the Napoleonic Wars Michel Ney. After service in the First World War, she became a depot ship and then an accommodation ship. Between 1922 and 1947, she was renamed three times, becoming successively Vivid, Drake and Alaunia II. She was scrapped in 1957.
HMS Prince Eugene was one of eight Lord Clive-class monitors built for the Royal Navy in 1915 to conduct shore bombardments during the First World War. The ship was assigned to the Dover Patrol for the duration of the war and provided cover for the Inshore Squadron during the First Ostend Raid. She was sold for scrap in 1921.
HMS General Wolfe, also known as Wolfe, was a Lord Clive-class monitor which was built in 1915 for shore-bombardment duties in the First World War. Her class of eight ships was armed by four obsolete Majestic-class pre-dreadnoughts which had their 12-inch guns and mounts removed, modified and installed in the newly built monitors. Wolfe spent her entire war service with the Dover Patrol, bombarding the German-occupied Belgian coastline, which had been heavily fortified. In the spring of 1918 she was fitted with an 18-inch (457 mm) gun, with which she made the longest-range firing in the history of the Royal Navy - 36,000-yard (20 mi) - on a target at Snaeskerke, Belgium. After the war, she was laid up before being stripped and put up for sale in 1920. She was finally scrapped in 1923.
HMS Sir John Moore was one of eight Lord Clive-class monitors built for the Royal Navy in 1915 to conduct shore bombardments during the First World War. The ship was assigned to the Dover Patrol for the duration of the war and was sold for scrap in 1921.
The Humber-class monitors were three large gunboats under construction for the Brazilian Navy in Britain in 1913. Designed for service on the Amazon River, the ships were of shallow draft and heavy armament and were ideally suited to inshore, riverine and coastal work but unsuitable for service at sea, where their weight and light draft reduced their speed from a projected twelve knots to under four. The class comprised Humber, Mersey and Severn. All three were taken over by the Royal Navy shortly before the outbreak of the First World War and were commissioned as small monitors. All three saw extensive service during the war and were sold in 1919.
HMS Severn was a Humber-class monitor of the Royal Navy. Originally built by Vickers for Brazil, she was purchased by the Royal Navy in 1914 on the outbreak of the First World War along with her sister ships Humber and Mersey. She had been christened Solimoes by the Brazilians, but was renamed by the British. The three ships were the first of a new type of specialized shore-bombardment warships. As a result of her shallow draught, she was very un-manoeuvrable and unseaworthy in open waters in anything more than a Force 5 wind.
HMS Havelock was an Abercrombie-class monitor of the Royal Navy that saw service in the First World War.
HMS Roberts was an Abercrombie-class monitor of the Royal Navy that served in the First World War.
The M15 class comprised fourteen monitors of the Royal Navy, all built and launched during 1915.
HMS M22 was a First World War Royal Navy M15-class monitor. Later converted to a minelayer and renamed HMS Medea, she was wrecked whilst being towed for breaking up on 2 January 1939.
The Arrol Gantry was a large steel structure built by Sir William Arrol & Co. at the Harland and Wolff shipyard in Belfast, Northern Ireland. It was built to act as overhead cranes for the building of the three Olympic-class liners.
