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 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 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 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 Albion-class ships of the line were a class of five 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
HMS Edgar was a 60-gun fourth rate ship of the line of the Royal Navy, launched on 16 November 1758 at Rotherhithe. The physician Thomas Denman served on Edgar until 1763. She was sunk as a breakwater in 1774.
The Exeter-class ships of the line were a class of four 64-gun third rates, designed for the Royal Navy by William Bateley.
The Ardent-class ships of the line were a class of seven 64-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 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 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 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 Mermaid-class frigates were a group of six 28-gun sailing frigates of the sixth rate designed in 1760 by Sir Thomas Slade, based on the scaled-down lines of HMS Aurora.
The Richmond-class frigates were 32-gun sailing frigates of the fifth rate produced for the Royal Navy. They were designed in 1756 by the Navy's Surveyor, William Bately, and were his equivalent of the Southampton-class frigates designed by Bately's co-Surveyor, Thomas Slade. They were faster ships than the Southamptons, and were weatherly craft, remaining dry even in high seas. Three ships were ordered to this design between 1756 and 1757, while a second batch of three ships was ordered between 1761 and 1762 to a slightly modified design.
The Niger-class frigates were 32-gun sailing frigates of the fifth rate produced for the Royal Navy. They were designed in 1757 by Sir Thomas Slade, and were an improvement on his 1756 design for the 32-gun Southampton-class frigates.
The Lively class were a successful class of sixteen British Royal Navy 38-gun sailing frigates.
The Banterer-class sailing sixth rates were a series of six 22-gun post ships built to an 1805 design by Sir William Rule, which served in the Royal Navy during the Napoleonic War. The first four were launched in 1806 and the remaining two in 1807. One ship – the Banterer – was lost in 1808 and another – the Cyane – captured by the United States Navy in 1815; the remaining four were all deleted during 1816.
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 Roebuck-class ship was a class of twenty 44-gun sailing two-decker warships of the Royal Navy. The class carried two complete decks of guns, a lower battery of 18-pounders and an upper battery of 9-pounders. This battery enabled the vessel to deliver a broadside of 285 pounds. Most were constructed for service during the American Revolutionary War but continued to serve thereafter. By 1793 five were still on the active list. Ten were hospital ships, troopships or storeships. As troopships or storeships they had the guns on their lower deck removed. Many of the vessels in the class survived to take part in the Napoleonic Wars. In all, maritime incidents claimed five ships in the class and war claimed three.
The Bordelois class was a class of 56-gun ships of the line, designed by Antoine Groignard. This was a unique type, designed to provide a battlefleet armament on a hull able to operate in the shallow waters around Dunkirk. The ships were funded by don des vaisseaux donations and rushed into production for the Seven Years' War, but were completed too late to take part in the conflict. The Flamand would later have a distinguished career during the War of American Independence.
