List of destroyer classes of the Royal Navy

Two Daring-class destroyers were the very first torpedo boat destroyers ("TBDs") to be ordered for the Royal Navy, the order being placed on 27 June 1892.

The Havock class was a class of torpedo boat destroyer (TBD) of the British Royal Navy. The two ships, Havock and Hornet, built in London in 1893 by Yarrow & Company, were the first TBDs to be completed for the Royal Navy, although the equivalent pair from J.I. Thornycroft, Daring and Decoy, were ordered five days earlier.

Two Ferret-class destroyers served with the Royal Navy. Ferret and Lynx were built by Laird, displaced 280 tons and were 199 feet (61 m) in overall length.

The A class as designated in 1913 was a heterogeneous group of torpedo boat destroyers (TBDs) built for the Royal Navy in the mid-1890s. Some 42 vessels were constructed to the individual designs of their builders to meet Admiralty specifications, the only uniting feature being a specified top speed of 27 knots (50 km/h). In fact the initial six vessels were generally differentiated by a slightly lower speed and were often referred to as "26-knotters" to distinguish them from the following batch of thirty-six vessels; all fifteen surviving "27-knotter" vessels were classified by the Admiralty as the A class in 1913 to provide some system to the naming of HM destroyers. All of the "26-knotters" and most of the "27-knotters" had been lost or scrapped before the 1913 classification, but for convenience all 42 ships are listed below. The number of funnels varied from one to four. All vessels had a distinctive "turtleback" forecastle that was intended to clear water from the bow, but actually tended to dig the bow in to anything of a sea, resulting in a very wet conning position.

The three Ardent-class torpedo boat destroyers were ordered by the British Admiralty on 12 October 1893 and served with the Royal Navy. Built by Thornycroft for a contract price of £110,520 for all three vessels, they displaced 301 tons fully laden, and were 201 feet 8 inches (61.47 m) long overall.

The three Charger-class destroyers were all ordered by the British Admiralty on 12 October 1893 and on completion in early 1896 they served with the Royal Navy until 1911.

Three Conflict-class destroyers served with the Royal Navy. All were built by the White Shipyard.

Two Fervent-class destroyers served with the Royal Navy. HMS Fervent and HMS Zephyr were designed and built by Hanna Donald in 1895. The ships displaced 275 tons and were 200 feet (61 m) long. Their locomotive boilers generated 3,850 shp (2,870 kW) which produced a top speed of between 26 and 27 knots. As was usual with ships of their type, they carried one 12-pounder, two torpedo tubes and had a complement of 53 officers and men.

The Banshee class was a class of three torpedo boat destroyers that served with the Royal Navy into the early part of the Twentieth century.

Three Handy-class destroyers served with the Royal Navy. Handy, Hart and Hunter were all built by Fairfield.

The Beagle class was a class of sixteen destroyers of the Royal Navy, all ordered under the 1908-1909 programme and launched in 1909 and 1910. The Beagles served during World War I, particularly during the Dardanelles Campaign of 1915.

The Acorn class was a class of twenty destroyers of the Royal Navy all built under the 1909-1910 Programme, and completed between 1910 and 1911. The Acorns served during World War I.

The Acheron class was a class of twenty-three destroyers of the British Royal Navy, all built under the 1910–11 Programme and completed between 1911 and 1912, which served during the First World War. A further six ships were built to the same design for the Royal Australian Navy as River-class destroyers. There was considerable variation between the design and construction of ships within this class, which should be considered as more of a post-build grouping than a homogeneous class.

The Acasta class was a class of twenty destroyers built for the Royal Navy under the Naval Programme of 1911 - 1912 that saw service during World War I. They were the last class of Royal Navy destroyers to have mixed names with no systematic theme When the class was designated as "K", names beginning with that letter were allocated to the ships but never used. The class saw extensive wartime service and seven were lost, including four at the Battle of Jutland.

HMS Swift was a unique destroyer leader designed and built for the Royal Navy prior to World War I, another product of Admiral "Jackie" Fisher's relentless quest for speed. The class was envisioned as a large ocean-going destroyer, capable of both the usual destroyer requirements and of high-speed scouting duties for a major fleet.

A flotilla leader was a warship of late 19th century and early 20th century navies suitable for commanding a flotilla of destroyers or other small warships, typically a small cruiser or a large destroyer. The flotilla leader provided space, equipment and staff for the flotilla commodore, including a wireless room, senior engineering and gunnery officers, and administrative staff to support the officers. Originally, older light or scout cruisers were often used, but in the early 1900s, the rapidly increasing speed of new destroyer designs meant that such vessels could no longer keep pace with their charges. Accordingly, large destroyer designs were produced for use as leaders.

The Laforey class was a class of 22 torpedo boat destroyers of the Royal Navy, twenty of which were built under the Naval Programme of 1912–13 and a further two under the 2nd War Emergency Programme of 1914. As such they were the penultimate pre-war British destroyer design. All served during World War I during which three were lost; the survivors were all scrapped in 1921-23.

HMS Arno was a unique destroyer of the Royal Navy that saw service and was lost during First World War. She was under construction in Genoa, Italy for the friendly Portuguese Navy as Liz in 1914 when she was bought by the Royal Navy for service in the Mediterranean.

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 Faulknor class were a class of flotilla leaders that were under construction in the United Kingdom for the Chilean Navy at the outbreak of World War I. Six ships were ordered by Chile, of which the first two were delivered to Chile before the outbreak of the war. The remaining four ships were purchased by the British, taken over and completed for the Royal Navy for wartime service. In common with Royal Navy convention, they were named after famous Royal Navy captains of the past, in this case the members of the Faulknor family.

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.

The County class was a class of British guided missile destroyers, the first such warships built by the Royal Navy. Designed specifically around the Seaslug anti-aircraft missile system, the primary role of these ships was area air defence around the aircraft carrier task force in the nuclear-war environment.

The Type 82 or Bristol-class destroyer was a 1960s guided missile destroyer design intended to replace County-class destroyers in the Royal Navy. Originally eight warships were planned to provide area air-defence for the planned CVA-01 aircraft carriers. They would also have been able to operate independently as modern cruisers "East of Suez".

CVA-01 was a proposed United Kingdom aircraft carrier, designed during the 1960s. The ship was intended to be the first of a class that would replace all of the Royal Navy's carriers, most of which had been designed before or during the Second World War. CVA-01 and CVA-02 were intended to replace HMS Victorious and HMS Ark Royal, while CVA-03 and CVA-04 would have replaced HMS Hermes and HMS Eagle respectively.

The Type 42 or Sheffield class, was a class of fourteen guided-missile destroyers that served in the Royal Navy. A further two ships of this class were built for and served with the Argentine Navy.

The Type 45 destroyer, also known as the D or Daring class, is a class of six guided-missile destroyers built for the United Kingdom's Royal Navy in the early 21st century. The class is primarily designed for anti-aircraft and anti-missile warfare and is built around the PAAMS air-defence system using the SAMPSON Active electronically scanned array (AESA) and the S1850M long-range radars. The first three destroyers were assembled by BAE Systems Surface Fleet Solutions from partially prefabricated "blocks" built at different shipyards; the remaining three were built by BAE Systems Maritime – Naval Ships. The first ship in the Daring class, HMS Daring, was launched on 1 February 2006 and commissioned on 23 July 2009.
