HMS Niger was originally slated to be built as a Sampson designed sloop; however, she was ordered as a First-Class sloop with screw propulsion on 20 February 1845 to be built at Woolwich Dockyard, along the design developed by Oliver Lang and with a hull like the Basilisk designed paddle sloops. Her armament and engine were to be like the Encounter Design building at Pembroke.

Niger She conducted important propulsion trials, finally proving the superiority of screw propulsion and served in West Africa, the Crimea, China, the East Indies and Australia. She took part in the New Zealand wars in 1860 and was sold for breaking in 1869.
HMS Brisk was a 14-gun wooden-hulled screw sloop designed by the Committee of Reference as part of the 1847 program. She is considered an enlarged Rattler with the design approved in 1847.

Her armament was to consist of 8 guns. She was to have a more powerful steam engine rated at 360 nominal horsepower. In 1848 she would be altered abaft and lengthened at Deptford prior to completion. 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.
HMS Reynard was part of the 1847 Program, she was ordered on 25 April as a steam schooner from Deptford Dockyard with the name ‘Plumper’. However, the reference Ships of the Royal Navy, by J.J. College, © 2020, there is no entry that associates the name Plumper to this build. The vessel was reordered on 12 August as an 8-gun sloop as designed by John Edye.

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.
