A second vessel (Harrier) was ordered on 26 March 1846 but after her keel was laid at Pembroke Dockyard, her construction was suspended on 9 September 1846 then cancelled five years later, on 4 April 1851. Encounter had her armament radically altered in 1850 and she was broken up at Devonport in 1866.
This group of vessels were originally slated to be built to the Sampson designed steam vessel; however, the Admiralty on 9 May 1845, ordered the first pair as First-Class screw sloops to be built from a design of Sir William Symonds, Surveyor of the Navy. This design would become known as the Conflict-class sloop. These would be 10-gun vessels with 400 NHP engines. The second pair of vessels were ordered on 26 March 1846 but after their keels were laid at Pembroke Dockyard, their construction was suspended in September 1846 then cancelled five years later, on 4 April 1851. Both completed ships served in the Baltic during the Crimean war, and Desperate briefly served as a store ship to Edward Augustus Inglefield's Arctic expedition. They had both been broken up by 1865.

On 26 March 1846, two vessels were ordered from Deptford Dockyard as Rifleman-designed gunvessels named Archer and Parthian. However, on 9 September 1846 the orders for both vessels were suspended prior to the vessels being laid down. On 25 April 1847 two vessels were ordered to the improved Rattler-type screw sloops as designed by John Edye of the Surveyor's Department from Deptford Dockyard. The first vessel, Archer may have been the change of the build from the Rifleman type to the sloop design. The second vessel, Wasp, appears to be a new vessel as the build for the Parthian remained on the books at Deptford until June 1849, when it was cancelled. Archer received the machinery from the gunvessel Rifleman, which resulted in an increase of speed over Wasp. Wasp's hull was sheathed in Muntz metal to retard marine growth. Their armament would increase from 12 to 15 guns over their careers. Both vessels would participate in the Russian War of 1854–1855. Both would be broken by 1869.
The Hermes class were a group of four vessels designed by John Edye of the Surveyor's Department to specifications outlined by Captain William Symonds, the Surveyor of the Navy.

The ships would be built in three Royal Dockyards, however, the Chatham vessel was transferred to Sheerness in 1837 prior to being laid down. Hermes was re-engined and lengthen in 1842, Megaera was wrecked in Jamaica in 1843. the remaining vessels served on many different stations of the Empire.

The changes included lengthening the bow by 10 feet to provide 6 feet of extra space in the engine room. Three vessels would have a single funnel whereas Scourge would have two and be completed as a bomb vessel. In July 1844 it was queried if Fury was to be completed as a screw vessel, however, since her construction was well along she would be completed as a paddle steamer. Four vessels were ordered and completed.
