The Hecla class was a class of bomb vessels of the Royal Navy of the early 19th century. They were designed for use as bomb or mortar ships and were very heavily built. Eight ships were launched; all were converted for use as exploration or survey ships. Four ships of the class are known for the role they played in Arctic and Antarctic exploration.
The Minerva-class sailing frigates were a series of four ships built to a 1778 design by Sir Edward Hunt, which served in the Royal Navy during the latter decades of the eighteenth century.
The Royal Oak-class ships of the line were a class of six 74-gun third rates, designed for the Royal Navy by Sir John Williams. The Alfred class were an enlarged version of the Royal Oak class.
The Intrepid-class ships of the line were a class of fifteen 64-gun third rates, designed for the Royal Navy by Sir John Williams. His design, approved on 18 December 1765, was slightly smaller than Sir Thomas Slade's contemporary Worcester-class design of the same year, against which it was evaluated competitively. Following the prototype, four more ships were ordered in 1767–69, and a further ten between 1771 and 1779.
The Caledonia-class ships of the line were a class of nine 120-gun first rates, designed for the Royal Navy by Sir William Rule. A tenth ship was ordered on 29 October 1827 to the same design, but was launched in 1833 as Queen to a fresh design by Sir William Symonds.
The Repulse-class ships of the line were a class of eleven 74-gun third rates, designed for the Royal Navy by Sir William Rule. The first three ships to this design were ordered in 1800, with a second batch of five following in 1805. The final three ships of the class were ordered towards the end of the Napoleonic War to a modified version of Rule's draught, using the new constructional system created by Sir Robert Seppings; all three were completed after the war's end.
The Nelson-class ships of the line were a class of three 120-gun first rates, designed for the Royal Navy as a joint effort between the two Surveyors of the Navy at the time, Robert Seppings and Joseph Tucker.
The Téméraire-class ships of the line were a class of a hundred and twenty 74-gun ships of the line ordered between 1782 and 1813 for the French navy or its attached navies in dependent (French-occupied) territories. Although a few of these were cancelled, the type was and remains the most numerous class of capital ship ever built to a single design.
The Canopus-class ships of the line were a class of nine 84-gun two-deck second rates of the Royal Navy. Their design was based on an enlarged version of the lines of the captured French ship Franklin, since commissioned in the Royal Navy as HMS Canopus, although this ship herself was not included as a member of the class. The earlier ships were initially ordered as 80-gun third rates, but this classification was altered by changes in the rating system in February 1817. This class of ships is sometimes referred to as the Formidable class.
The Vanguard-class ships of the line were a class of two-deck 80-gun second rates, designed for the Royal Navy by Sir William Symonds, of which nine were completed as sailing ships of the line, although another two of these were completed as steam warships.
The Pallas-class frigates were a series of three frigates built to a 1791 design by John Henslow, which served in the Royal Navy during the French Revolutionary and Napoleonic Wars.
The Lively class were a successful class of sixteen British Royal Navy 38-gun sailing frigates.
The Conway class sailing sixth rates were a series of ten Royal Navy post ships built to an 1812 design by Sir William Rule. All ten were ordered on 18 January 1812, and nine of these were launched during 1814, at the end of the Napoleonic War; the last (Tees) was delayed and was launched in 1817.
The Hermes class were a series of four 20-gun ships, launched between 1811 and 1816. Two pairs of ships were produced, to slightly different designs – the first two had 20 guns and were unrated flush-decked ship-sloops, whilst the latter two were converted to 26-gun sixth-rates. The design was based on the ex-French 20-gun corvette Bonne Citoyenne, which the British had captured in 1796.
The Seringapatam-class frigates, were a class of British Royal Navy 46-gun sailing frigates.
The Apollo-class sailing frigates were a series of twenty-seven ships that the British Admiralty commissioned be built to a 1798 design by Sir William Rule. Twenty-five served in the Royal Navy during the Napoleonic Wars, two being launched too late.
The Scamander class sailing frigates were a series of ten 36-gun ships, all built by contract with private shipbuilders to an 1812 design by Sir William Rule, which served in the Royal Navy during the late Napoleonic War and War of 1812.
The Atholl-class corvettes were a series of fourteen Royal Navy sailing sixth-rate post ships built to an 1817 design by the Surveyors of the Navy. A further four ships ordered to this design were cancelled.
A number of ships of the Royal Navy have borne the name HMS Dee, after one or other of the British rivers called the Dee.
The Agamemnon-class steam battleships, or steam ships of the line, were a class of five 91-gun steam second rates of the Royal Navy. The original design was produced by John Edye in 1847, as a response to the French Le Napoléon, which was rumoured to be under development.
