HMS Encounter was ordered as a First-Class Sloop with screw propulsion on 5 February 1845 to be built at Pembroke, in accordance with the design developed by John Fincham, Master Shipwright at Portsmouth. Her armament was to consist of 8 guns (2 × 85 cwt, 4 × 65 cwt and 2 × 25 cwt). 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.

Encounter was the third named vessel since its introduction for a discovery vessel in service in 1616.

Harrier was the fourth named ship since the name was introduced for a ‘Cruizer’ class fir built 18-gun brig sloop, launched by Barnard of Deptford on 22 April 1804 and foundered in the Indian Ocean in March 1809.
