The M29 class comprised five monitors of the Royal Navy, all built and launched during 1915.
HMS Victorious was one of nine Majestic-class pre-dreadnought battleships of the British Royal Navy. She was armed with a main battery of four 12-inch (305 mm) guns in two twin turrets, and was capable of a top speed of 16 knots. She served primarily on home waters, and participated in the Fleet Review for the Diamond Jubilee for Queen Victoria in 1897. She served briefly in the Mediterranean in 1898 before being transferred to the China Station later that year; Victorious remained in East Asian waters until 1900, when she returned to the Mediterranean.
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.
HMS Abercrombie was a First World War Royal Navy Abercrombie-class monitor.
HMS Centaur was a C-class light cruiser of the Royal Navy that served in the First World War and the Russian Civil War. She was the name ship of the Centaur group of the C-class of cruisers.
HMS Earl of Peterborough was a First World War Royal Navy Lord Clive-class monitor, named after Charles Mordaunt, 3rd Earl of Peterborough, a British general of the War of the Spanish Succession who fought in Spain. The ship's original 12-inch main battery was stripped from an obsolete Majestic-class battleship, HMS Mars.
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 Sir Thomas Picton was a First World War Royal Navy Lord Clive-class monitor. Sir Thomas Picton was the only Royal Navy ship ever named for Sir Thomas Picton, a British general of the Peninsular War who was killed at the Battle of Waterloo. The ship's original 12" main battery was stripped from the obsolete Majestic-class battleship HMS Mars.
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 Craufurd was the one of eight Lord Clive-class monitors built for the Royal Navy during World War I. Their primary armament was taken from obsolete pre-dreadnought battleships. The ship spent the war in the English Channel bombarding German positions along the Belgian coast as part of the Dover Patrol. She participated in the failed First and Second Ostend Raids in 1918, bombarding the defending coastal artillery as the British attempted to block the Bruges–Ostend Canal. Later that year General Craufurd supported the coastal battles during the Hundred Days Offensive until the Germans evacuated coastal Belgium in mid-October. The ship was decommissioned almost immediately after the war ended the following month, but she was reactivated in 1920 to serve as a gunnery training ship for a year. General Craufurd was sold for scrap in 1921.
HMS Lord Clive was the lead ship of her class of eight monitors built for the Royal Navy during World War I. Their primary armament was taken from obsolete pre-dreadnought battleships. The ship spent the war in the English Channel bombarding German positions along the Belgian coast as part of the Dover Patrol, often serving as a flagship. She participated in the failed First Ostend Raid in 1918, bombarding the defending coastal artillery as the British attempted to block the Bruges–Ostend Canal. Lord Clive was one of two ships in the class fitted with a single 18-inch (457 mm) gun in 1918, but she only fired four rounds from it in combat before the end of the war in November. The ship conducted gunnery trials after the war and was sold for scrap in 1927.
HMS Marshal Soult was a Royal Navy Marshal Ney-class monitor constructed in the opening years of the First World War. Laid down as M14, she was named after the French general of the Napoleonic Wars Marshal Nicolas Jean de Dieu Soult. She served in both World Wars and was decommissioned in 1946.
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 Roberts was a Royal Navy Roberts-class monitor of the Second World War. She was the second monitor to be named after Field Marshal Frederick Roberts, 1st Earl Roberts.
HMS Abercrombie was a Royal Navy Roberts-class monitor of the Second World War. She was the second monitor to be named after General Sir Ralph Abercrombie.
