The Lowestoffe class were a class of two 28-gun sixth-rate frigates of the Royal Navy. They served during the Seven Years' War, with HMS Tartar surviving to see action in the American War of Independence and the French Revolutionary Wars.
The Coventry-class frigates were 28-gun sixth rate frigates of the Royal Navy, principally in service during the Seven Years' War and the American Revolutionary War. They were designed in 1756 by Britain's Surveyor of the Navy, Sir Thomas Slade, and were largely modeled on HMS Tartar, which was regarded as an exemplar among small frigates due to its speed and maneuverability. The 1750s were a period of considerable experimentation in ship design, and Slade authorized individual builders to make "such alterations withinboard as may be judged necessary" in final construction.
The Canada-class ships of the line were a series of four 74-gun third rates designed for the Royal Navy by William Bateley. The name ship of the class was launched in 1765.
The Bellona-class ships of the line were a class of five 74-gun third rates, whose design for the Royal Navy by Sir Thomas Slade was approved on 31 January 1758. Three ships were ordered on 28 December 1757, with names being assigned on 1 February 1758. Two further ships to this design were ordered on 13 December 1758, at the same time as two ships of a revised design – the Arrogant class.
The Hercules class ships of the line were a class of two 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Dublin-class ships of the line were a class of seven 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Sandwich class ships of the line were a class of three 90-gun second rates, designed for the Royal Navy by Sir Thomas Slade.
The Ramillies-class ships of the line were a class of nine 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Albion-class ships of the line were a class of five 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
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 Culloden-class ships of the line were a class of eight 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade. The Cullodens were the last class of 74s which Slade designed before his death in 1771.
The Alfred-class ships of the line were a class of four 74-gun third rates for the Royal Navy by Sir John Williams. They were an enlarged version of the Royal Oak class.
The Courageux-class ships of the line were a class of six 74-gun third rates of the Royal Navy. Their design was a direct copy of the French ship Courageux, captured in 1761 by HMS Bellona. This class of ship is sometimes referred to as the Leviathan class. A further two ships of the class were built to a slightly lengthened version of the Courageux draught. A final two ships were ordered to a third modification of the draught.
The Fame-class ships of the line were a class of four 74-gun third rates, designed for the Royal Navy by Sir John Henslow. After the name-ship of the class was ordered in October 1799, the design was slightly altered before the next three ships were ordered in February 1800. A second batch of five ships was ordered in 1805 to a slightly further modified version of the original draught.
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 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 Burford class were three 68-gun third-rate ships of the line designed for the Royal Navy by Sir Joseph Allin. The Burford ships were almost the last "70-gun" ships designed by Allin. They were built to the draught specified by the 1745 Establishment as amended in 1754.
The Temple class ships were two 68-gun third rates designed for the Royal Navy to the lines of the Vanguard of 1748, i.e. to the outdated 1745 Establishment. The Temple class ships were the last 68-gun ships to be built - both by commercial contract - to the draught specified by the 1745 Establishment.
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.
