The Abercrombie class of monitors served in the Royal Navy during the First World War.

History

The four ships in this class came about when the contracted supplier of the main armament for the Greek battleship Salamis being built in Germany was unable to supply due to the British blockade. The company – Bethlehem Steel in the United States – instead offered to sell the four 14 in (356 mm) twin gun turrets to the Royal Navy on 3 November 1914.^[1] The Royal Navy was using obsolete pre-dreadnought battleships for shore bombardment in support of the army in Belgium, and a design for a shallow-draught warship (known as "Monitors") suitable for shore-bombardment was quickly designed and built to use these turrets. The ships were laid down and launched within six months.^[1]

The ships carried a single main gun turret forward of a tripod mast, which was itself in front of a single funnel. A secondary armament of two 12-pounder (76 mm) guns was fitted, with a single 3-pounder (47 mm) anti-aircraft gun, with a 2-pounder pom-pom completing the ships armament.^[2]

The monitors had a box-like hull, with very bluff bow and stern, and were fitted with anti-torpedo bulges. In order to speed construction, it was intended to use off-the shelf merchant ship engines, giving about 2,000 indicated horsepower (1,500 kW), which were expected to drive the ships to 10 knots (19 km/h; 12 mph). The rushed design, however, meant that the ships were much slower than expected — Raglan's engines gave 2,310 indicated horsepower (1,720 kW) but the ship could only reach 6+1⁄2 knots (12.0 km/h; 7.5 mph).^[3]

During the planning and build, they were to be the Styx-class named after four American figures; General Ulysses S. Grant, General Robert E. Lee, Admiral David Farragut and General Stonewall Jackson and they were launched under these names. Because the United States was still a neutral power at that time, using these names would have been undiplomatic and so they were renamed as simply M1 through M4 before completion, then receiving their final names.

The design included a seaplane for spotting the guns, but it was found that land-based aircraft were more effective; as monitors, they would never operate in the open sea, and storing the seaplane on top of the turret meant it had to be removed to avoid damage, even if not required before the guns could fire.

The Highflyer-class cruisers were a group of three second-class protected cruisers built for the Royal Navy in the late 1890s.

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 Starfish was an R-class destroyer which served with the Royal Navy. She was launched on 27 September 1916 and sold to be broken up on 21 April 1928. She was built by Hawthorn Leslie of Hebburn Tyne.

HMS Torrent was a Royal Navy R-class destroyer constructed and then operational in the First World War. She was sunk, with most of her crew in 1917. On 23 December 1917 Surprise, HMS Torrent, and Tornado sank after entering an Imperial German minefield.

HMS Retriever was a Thornycroft-built R-class destroyer which served with the Royal Navy during the First World War. Launched in 1917, the vessel formed part of the Harwich Force and took part in operations off the coast of Ostend in support of the bombardment of the town in June that year. During August the following year, the vessel attempted to deploy a seaplane from a towed lighter, but a lack of wind meant the operation was unsuccessful. The vessel was also jointly credited with the destruction of the submarine SM UB-54 that year, although this has been disputed. After the war, the ship was placed in reserve and was sold to be broken up in 1927.

HMS Satyr was an R-class destroyer which served with the Royal Navy during the First World War. Launched on 27 December 1916, Satyr joined the Harwich Force under the command of Commander Hubert de Burgh. In 1917, the destroyer formed part of a force protecting the monitors Erebus and Terror in their bombardment of Ostend. As part of this action, Satyr, along with sister ships Taurus, Sharpshooter and Torrent, sank the German destroyer S20. After the war, the ship served with the Torpedo School at the Devonport. In 1923, the Navy decided to retire many of the older destroyers in preparation for the introduction of newer and larger vessels and Satyr was sold to be broken up on 16 December 1926.

HMS Tilbury was a S-class destroyer of the British Royal Navy that served during the First World War.

HMS Sharpshooter was an R-class destroyer which served with the Royal Navy during World War I. Launched on 27 February 1917, the ship joined the Harwich Force, undertaking convoy escort duties. The vessel also took part in the Navy’s bombardment of Ostend later that year. On 1 June 1918, the destroyer rescued Captain A. C. Sharwood, one of the first pilots of the Royal Australian Navy, who ditched his Sopwith 2F.1 Camel nearby. After the war, Sharpshooter joined the Navy gunnery training establishment at Plymouth, but did not stay long and was reduced to Reduced Complement on 5 March 1919. The Royal Navy was rationalising its destroyer force and Sharpshooter, deemed superfluous, was sold to be broken up on 29 April 1927.

HMS Simoom was an R-class destroyer which served with the Royal Navy during World War I. Launched on 30 October 1916, the vessel operated as part of the Harwich Force until torpedoed by the German destroyer S50 on 23 January 1917. The ship's magazine exploded and 47 people died. The name was reused by the first S-class destroyer, Simoom, launched on 26 January 1918.

HMS Rigorous was an R-class destroyer which served with the Royal Navy during World War I. Launched on 30 September 1916, the vessel operated as part of the Grand Fleet, operating as part of destroyer flotillas hunting German ships that were attacking convoys. One flotilla was successful in destroying a Q ship in 1917. After the War, the destroyer was given a reduced complement and was sold to be broken up on 5 November 1926.

HMS Restless was an R-class destroyer which served with the Royal Navy during World War I. Launched on 12 August 1916, the ship operated as part of the Grand Fleet, operating as part of a destroyer flotilla protecting convoys in the North Sea. After the War, the destroyer served in the Mediterranean Sea and was sold to be broken up on 23 November 1936.

HMS Rowena was an R-class destroyer which served with the Royal Navy during World War I. Launched on 1 July 1916, the ship operated as part of the Grand Fleet as part of a destroyer flotilla hunting for German vessels that were attacking convoys in the North Sea. Although there were many reported sightings, no submarines were sunk. After the conflict, the vessel was transferred to the Navy’s establishment at Portland to help in the development of anti-submarine warfare, which ultimately helped in the Battle of the Atlantic. Rowena did not, however, see the fruit of this labour. After twenty years of service, the destroyer was retired and sold to be broken up on 27 January 1937.

HMS Romola was an R-class destroyer which served with the Royal Navy during World War I. Launched on 14 May 1916, the ship operated as part of the Grand Fleet, operating as part of a destroyer flotilla. The ship sailed to intercept the German High Seas Fleet in what would be one of the last major expeditions of their Navy in the war but saw no action. After the conflict, the destroyer was held in reserve until being retired and sold to be broken up on 13 March 1930.

HMS Linnet was a Laforey-class destroyer that served with the Royal Navy during the First World War. Launched on 16 August 1913 as HMS Havock, the ship was renamed on 30 September under an Admiralty order to become one of the first destroyers in a class named alphabetically. This convention subsequently became the norm. On commissioning, the vessel joined the Third Destroyer Flotilla and operated as part of the Harwich Force. The destroyer was first commanded by Commander Loftus Jones who named his daughter Linnette after the ship. During the War, the destroyer took part in the Battle of Heligoland Bight in 1914, and escorted minelayers on missions to lay mines. It was during one the latter missions that the ship was nearly hit by a gun hurled from the stricken minelayer Amphion. With the cessation of hostilities, the ship was placed in reserve and sold to be broken up on 4 November 1921.

HMS Serene was an S-class destroyer, which served with the Royal Navy. Launched on 30 November 1918 just after the end of the First World War, the ship was commissioned into the Reserve Fleet. Excluding a brief expedition to Latvia near to the end of that nation's War of Independence in 1919, the destroyer remained in reserve at Devonport until 1936. During this period, the condition of the destroyer deteriorated. Then, as part of a deal for the liner Majestic, Serene was sold to be broken up on 14 September.
