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 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 Barfleur-class ships of the line were a class of four 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 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 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 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 Worcester-class ships of the line were a class of three 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
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 Annibal class was a class of two 74-gun ships of the French Navy. The type was one of the first achievements of Jacques-Noël Sané. His first design - on 24 November 1777 - was for a ship of 166 pieds length, but he produced an amended design on 10 January 1779 for the Annibal, and a further amended design on 3 March 1780 for her near-sister Northumberland. Both ships were captured during the Fourth Battle of Ushant on 1 June 1794 off Ushant, and were added to but never commissioned into the British Navy.
The Albion-class ships of the line were a class of two-deck 90-gun second rates, designed for the Royal Navy by Sir William Symonds. The first two were originally ordered in March 1840 as 80-gun ships of the Vanguard class, but were re-ordered to a new design of 90 guns some three months later. Three more ships to this design were ordered in March 1840, but two of these were re-ordered to fresh designs in 1847.
The Iphigénie class was a group of nine 32-gun/12-pounder frigates of the French Navy, built during the late 1770s at Lorient and Saint Malo. They were designed by Léon Guignace. The seven built at Saint Malo were initially numbered Nos. 1 – 7 respectively, and not given names until October 1777 and the start of 1778 ; all seven were captured by the British Navy between 1779 and the end of 1800. Of the two built at Lorient, the Spanish captured one, and a storm wrecked the other.
The Lively class were a successful class of sixteen British Royal Navy 38-gun sailing frigates.
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 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 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.
