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 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 Black Prince-class ships of the line were a class of four 74-gun third rates built for the Royal Navy in the closing years of the Napoleonic War. The draught for this class of ship was essentially a reduced version of the captured Danish ship Christian VII.
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 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.
