HMS Acorn was a destroyer of the British Royal Navy and the lead ship of her class. She was built by John Brown and Company at their Clydebank shipyard, being built and completed in 1910. The ship served throughout the First World War and was sold for scrap in 1921.
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 Ulster was a modified Admiralty R-class destroyer that served in the Royal Navy during the First World War. The Modified R class added attributes of the Yarrow Later M class to improve the capability of the ships to operate in bad weather. Launched on 10 October 1917, the vessel served with the Grand Fleet. After the war, the destroyer was placed initially in the Home Fleet, but then moved to the Reserve Fleet before, on 21 April 1928, being sold to be broken up.
HMS Radstock was the first in a class of 62 R-class destroyers. The design differed from the preceding M-class primarily in the use of geared turbines, which gave better fuel efficiency. The ship was launched in 1916 and served with the Grand Fleet of the Royal Navy during World War I as in an escort and anti-submarine role. While escorting a convoy in 1918, the destroyer collided with the merchant ship Volute, but otherwise had an uneventful war. After the Armistice of 11 November 1918 that ended the war, the vessel was recommissioned with reduced complement and joined the Reserve Fleet. Radstock stayed in Reserve until 1927. By this time, the vessel had deteriorated and, despite having a refit in 1925, was deemed unfit for service and was sold to be broken up.
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 S-class destroyer which served with the Royal Navy. Launched on 26 January 1918, the vessel operated as part of the Grand Fleet during the last months of World War I. At the end of the conflict, Simoom was placed in reserve and scrapped on 8 January 1931. The name was reused from an R-class destroyer sunk on 23 January 1917.
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 Tara was an S-class destroyer, which served with the Royal Navy. Launched on 7 August 1918, the vessel entered service at the closing of the First World War. The ship joined the Fourteenth Destroyer Flotilla of the Grand Fleet but was placed in Reserve at Nore in 1919. Tara deteriorated over the following years and was sold to be broken up on 17 December 1931 after the signing of the London Naval Treaty that limited the amount of destroyer tonnage the Navy could retain.
HMS Trojan was an S-class destroyer, which served with the Royal Navy. The vessel was the only one named in honour of the citizens of Troy that has been operated by the navy. Launched on 12 July 1918, Trojan was too late to see service in the First World War. Initially allocated to the Grand Fleet and then, when this was dissolved, the Atlantic Fleet, the destroyer was transferred to the Reserve Fleet, like many of the class, within two years of being first commissioned. The vessel remained in reserve until 24 September 1936, although in a deteriorating condition. On that day, Trojan was sold to be broken up as part of a deal for the liner Majestic.
HMS Sepoy was an S-class destroyer, which served with the Royal Navy during the First World War and the Russian Civil War. Sepoy was launched in 1918 and initially joined the Grand Fleet. After the Armistice that ended the First World War, the ship was briefly transferred to the Reserve Fleet before sailing to Tallinn in 1919 as part of the Royal Navy response to the fighting there. Sepoy rejoined the Reserve Fleet at the end of the year. In 1922, the destroyer served in the Mediterranean Sea. The ship was later allocated to the naval base in Hong Kong, arriving in 1929. During exercises the following year, a depth charge explosion killed six sailors. The destroyer was also damaged. Following the signing of the London Naval Treaty a few days later, Sepoy returned to the United Kingdom and, in 1932, was sold to be broken up at Newport, Wales.
HMS Sesame was an S-class destroyer, which served with the Royal Navy in the twentieth century. Launched on 30 November 1918 just after the end of the First World War, the ship was commissioned into the Reserve Fleet. A year later, the destroyer was sent to Latvia in support of the country's call for independence, arriving just at the cessation of that county's war of independence. Returning to the United Kingdom, Sesame was later equipped to act as a plane guard within the Home Fleet, with all armament removed and a davit fitted to rescue aircraft. The vessel remained in that configuration for a short time, but the London Naval Treaty sounded the death knell for the ship as it limited the destroyer tonnage that the Royal Navy could operate. As newer and more powerful destroyers entered service, Sesame was one of those retired, being sold to be broken up on 4 May 1934.
HMS Pellew was a Admiralty M-class destroyer which served with the Royal Navy during the First World War. The M class were an improvement on the preceding L class, capable of higher speed. Launched on 18 April 1916, the vessel served with the Grand Fleet escorting convoys. The vessel was part of an unsuccessful attempt by the navy to trap the German submarines that had taken such a heavy toll on merchant shipping in December 1917. The action involved an eight-ship convoy consisting of four merchant vessels escorted by two armed trawlers and the sister ships Pellew and Partridge. Instead of submarines, four German destroyers attacked, sinking all but one member of the convoy and disappearing before the light cruisers which were to be the spring in the trap could arrive. Pellew, the sole survivor, took refuge in a Norwegian fjord. After the armistice that ended the war, the destroyer was placed in reserve and subsequently sold to be broken up on 9 May 1921.
HMS Pelican was a Admiralty M-class destroyer which served with the Royal Navy during the First World War. The M class were an improvement on the preceding L class, capable of higher speed. Launched on 18 March 1916, the vessel served with the Grand Fleet, taking part in significant actions on 19 August 1916 and 4 May 1917, as well as the fight between the British and German battlecruisers in the Battle of Jutland. The destroyer also undertook the other more general roles were typical of the type, including anti-submarine sweeps and escort duties for convoys. The destroyer had success driving away German submarines but did not sink any. After the end of the war, Pelican initially joined a Local Defence Flotilla but within a year had been placed in reserve and was subsequently sold to be broken up on 9 May 1921.
HMS Mons was an Admiralty M-class destroyer which served with the Royal Navy during the First World War and fought in the Battle of Jutland. The M class was an improvement on the preceding L class, capable of higher speeds. The ship, the first British naval vessel to be named after the Battle of Mons, was launched in 1915. Joining the Grand Fleet as part of the new Eleventh Destroyer Flotilla, the destroyer was soon in action, taking part in patrols that aimed to draw out the German High Seas Fleet. During the Battle of Jutland in 1916, Mons attacked the German light cruisers at the forefront of the German battleline but scored no hits. After the armistice, the destroyer was placed in reserve. Mons was found to be worn out by wartime operations and, despite only serving for six years, in 1921, was sold to be broken up.
HMS Mameluke was an Admiralty M-class destroyer which served with the Royal Navy during the First World War. The M class was an improvement on the preceding L class, capable of higher speeds. The ship, the first Royal Navy vessel to be named after the Mamelukes, a class of ex-slaves that ruled Egypt, was launched in 1915. The destroyer joined the Twelfth Destroyer Flotilla and, although under refit during the Battle of Jutland and so unable to participate, later took part in anti-submarine operations as part of this flotilla, although no submarines were sighted or sunk. The conditions of service in the North Sea meant that the destroyer was soon worn out and, after the armistice, Mameluke was placed in reserve. Despite a service life of only six years, the vessel was decommissioned and, in 1921, sold to be broken up.
HMS Tancred was an R-class destroyer which served with the Royal Navy during the First World War. The R class were an improvement on the previous M class with geared steam turbines to improve efficiency. Launched by Beardmore of Dalmuir on 30 June 1917, Tancred initially joined the Grand Fleet, serving as part of a flotilla that took part in one of the last naval actions of the war, although in this case the British vessels did not engage with the German High Seas Fleet. After the signing of the Armistice that ended the war and the dissolution of the Grand Fleet, the destroyer was initially transferred to the Home Fleet. However, within a year, Tancred had been allocated to the local defence flotilla at Firth of Forth. Despite being at a reduced complement as an economy measure, further reductions in fleet costs meant that the destroyer was retired. On 17 May 1928, Tancred was sold to be broken up.
HMS Octavia was an Admiralty M-class destroyer which served in the Royal Navy during the First World War. The M class were an improvement on the previous L-class, capable of higher speed. The vessel was launched on 21 June 1916 and joined the Grand Fleet. Octavia joined the Thirteenth Destroyer Flotilla, which, in 1917, participated in a large anti-submarine warfare operation in the North Sea. The sortie led to three German submarines being sunk, although Octavia was not directly involved in these attacks. In 1918, the flotilla was involved in one of the final sorties of the Grand Fleet, but again the destroyer saw no action at the time. After the Armistice that marked the end of the First World War, Octavia was placed in reserve, decommissioned and, on 5 November 1921, sold to be broken up.
