The V and W class was an amalgam of six similar classes of destroyer built for the Royal Navy under the 9th, 10th, 13th and 14th of fourteen War Emergency Programmes during the First World War and generally treated as one class. For their time they were among the most powerful and advanced ships of their type in the world, and set the trend for future British designs.
The River-class destroyer was a class of torpedo boat destroyer built for the Royal Navy at the turn of the 20th century, and which saw extensive service in World War I. The class introduced new features to destroyer design, placing a greater emphasis on seakeeping and endurance and less on a high maximum speed in good weather. All the ships were named after British and Irish rivers, and as such were the first Royal Navy destroyer class to be named systematically.
The C class as designated in 1913 was a heterogeneous group of torpedo boat destroyers (TBDs) built for the Royal Navy in the late-1890s. They were constructed to the individual designs of their builders to meet Admiralty specifications. The uniting feature of the class was a top speed of 30 knots, a "turtleback" forecastle and that they all had three funnels. The funnels were spaced equidistantly and were of equal height, but the central one was thicker.
The Admiralty type leader, sometimes known as the Scott class, were a class of eight destroyer leaders designed and built for the Royal Navy towards the end of World War I. They were named after Scottish historical leaders. The function of a leader was to carry the flag staff of a destroyer flotilla, therefore they were enlarged to carry additional crew, offices and signalling equipment, allowing a fifth gun to be carried. These ships were contemporary with the Thornycroft type leader, distinguishable by their two narrow funnels of equal height, the Thornycroft designs latter having characteristic broad, slab-sided funnels.
The Yarrow M class was a class of ten destroyers built for the Royal Navy that saw service during World War I. They were generally similar to the standard Admiralty M-class destroyer, but were instead designed by the builder, Yarrow & Company. Generally, they had two instead of three shafts, as well as two funnels and a straight stern, with the bridge set well back from the forecastle. The first trio were two knots faster than the Admiralty M type, despite less installed power and one less shaft; the installed power was increased for the later vessels. Jane's Fighting Ships describes the class as "very successful boats", and all ten vessels survived throughout the war to be broken up during the 1920s. Moon, Mounsey and Musketeer were each fitted to carry a kite balloon.
The M class, more properly known as the Admiralty M class, were a class of 85 destroyers built for the Royal Navy of United Kingdom that saw service during World War I. All ships were built to an identical – Admiralty – design, hence the class name. 18 other vessels which were officially included within the 'M' class were built to variant designs by three specialist builders – 10 by Yarrow, 6 by Thornycroft, and 2 by Hawthorn Leslie; these are covered in other articles.
The Thornycroft M or Mastiff class were a class of six British destroyers completed for the Royal Navy during 1914–16 for World War I service. They were quite different from the Admiralty-designed ships of the Admiralty M class, although based on a basic sketch layout provided by the Admiralty from which J I Thornycroft developed their own design. Like the 'standard' Admiralty M class they had 3 funnels, but the centre funnel was thicker in the Thornycroft ships. The midships 4 in gun was shipped between the 2nd and 3rd funnels. Patriot was fitted to carry a kite balloon.
The first R class were a class of 62 destroyers built between 1916 and 1917 for the Royal Navy. They were an improvement, specifically in the area of fuel economy, of the earlier Admiralty M-class destroyers. The most important difference was that the Admiralty R class had two shafts and geared turbines, compared with the three shafts and direct turbines of the Admiralty M class, but in appearance the R class could be distinguished from its predecessors by having the after 4-inch gun mounted in a bandstand. The Admiralty ordered the first two of this class of ships in May 1915. Another seventeen were ordered in July 1915, a further eight in December 1915, and a final twenty-three in March 1916.
The Marksman class were a class of flotilla leaders built for the Royal Navy. Two each were ordered in the naval programmes of 1913–14 and 1914–15 with a further three being ordered under the Emergency War Programme and all saw service during World War I.
HMS Derwent was a Hawthorn Leslie-type River-class destroyer ordered by the Royal Navy under the 1901 – 1902 Naval Estimates. Named after the River Derwent in central England, she was the second ship to carry this name.
HMS Waveney was a Hawthorn Leslie-type River-class destroyer ordered by the Royal Navy under the 1902–1903 Naval Estimates. Named after the River Waveney in eastern England, she was the first ship of the Royal Navy to carry this name.
HMS Boyne was a Hawthorn Leslie type River-class destroyer ordered by the Royal Navy under the 1903 – 1904 Naval Estimates. Named after the River Boyne in Ireland, the site of a British military victory in 1689, she was the fifth ship to carry this name since it was introduced in 1692 for a two deck ship-of-the-line.
HMS Doon was a Hawthorn Leslie type River-class destroyer ordered by the Royal Navy under the 1903 – 1904 Naval Estimates. Named after the River Doon in western Scotland, she was the first ship to carry this name in the Royal Navy.
HMS Mermaid was a Hawthorn Leslie three-funnel, 30 knot destroyer ordered by the Royal Navy under the 1896 – 1897 Naval Estimates. She was launched in 1898, served during World War I and was sold for breaking in 1919.
HMS Cheerful was a 30-knot, three-funnel torpedo boat destroyer built by Hawthorn Leslie. She was ordered by the Royal Navy under the 1896–1897 Naval Estimates, launched in 1898 and saw action during World War I. She was mined off the Shetland Islands in 1917 and sank with the loss of 44 officers and men.
HMS Greyhound was a Hawthorn Leslie three-funnel, 30 knot destroyer ordered by the Royal Navy under the 1898 – 1899 Naval Estimates.
HMS Racehorse was a three-funnel, 30-knot torpedo boat destroyer built by Hawthorn Leslie for the Royal Navy. Ordered by the Royal Navy under the 1898–1899 Naval Estimates, she was the eighth ship to carry this name since it was introduced in 1757. She served in World War I and was sold for breaking in 1920.
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 Plover 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 previous L-class, capable of higher speed. Launched on 3 March 1916 by Hawthorn Leslie on the River Tyne, the vessel served as part of the Grand Fleet. Plover was based at Scapa Flow and took part in sorties in response to German submarine activity. After an uneventful war, the destroyer was placed in reserve and decommissioned, being sold to be broken up on 9 May 1921.
HMS Pigeon was an Admiralty M-class destroyer which served with the Royal Navy during the First World War. The M class were an improvement on the previous L-class destroyer, capable of higher speed. Launched on 3 March 1916 by Hawthorn Leslie on the River Tyne, the vessel served as part of the Grand Fleet. Pigeon was mainly involved in escorting convoys. After an unsuccessful sortie in October 1917 against German cruisers, the destroyer moved to anti-submarine warfare. In this arena, Pigeon had some success in 1918, rescuing the survivors from the sinking troopship Tuscania in February and assisting in the destruction of the German U-boat UB-124 in July. After the Armistice, the destroyer was redeployed to serve as part of the Nore Local Defence flotilla until being decommissioned and sold to be broken up on 9 May 1921.
