Launched in March 1778, she was commissioned in January 1779 for service in British home waters and the Caribbean, under the command of Captain
Edward Thompson. She saw active service in the blockade and capture of French-controlled
Gorée in April 1779, and eight months later was part of
Admiral George Rodney's fleet which sailed to the
naval relief of Gibraltar in January 1780.
Hyaena then returned to England, bearing reports of the battle and the disposition of Admiral Rodney's fleet. In August 1780, still under Thompson's command,
Hyaena escorted a merchant convoy to New York and then turned south to the Caribbean. Thompson's orders were to use his ship and any other forces at his disposal to secure British control of Dutch settlements of
Demerara and
Essequibo. This was achieved despite a lack of resources, with
Hyaena subsequently escorting merchant convoys between these new
British possessions and the larger port of Barbados, and thence to England. Convoy in tow,
Hyaena reached England in January 1782. Eighteen months in tropical waters had left her in poor condition, and she was promptly decommissioned and sailed to Woolwich dockyards for repair. The works were extensive and were completed at a final expense of £5,561, more than half the cost of
Hyaenas original construction four years earlier. While
Hyaena was out of service her captain, Edward Thompson, had been assigned to the newly built , a 50-gun ship of the line. Command of
Hyaena passed to Captain Patrick Sinclair, whose orders were to protect shipping in the seas immediately surrounding the British Isles. Recommissioned in January 1783,
Hyaena took up this new role in April and remained at this station for the next five years. In 1784, she was briefly under the command of the Honourable M.De Courcy (Acting), until Sinclair resumed command. In 1787 De Courcy took command of
Hyaena on the Irish station. May saw
Hyaena serving as the initial escort for the convoy of ships that would become the
First Fleet to Australia, sailing alongside the fleet to a point two hundred miles west of the
Scilly Isles. While undertaking this escort it was discovered that the convict storeship was five crew members short. This was addressed by requiring five of
Hyaenas crew to transfer to
Fishburn for the eight-month voyage to Australia. In 1788
Hyaena was again decommissioned to allow a four-month refit at Plymouth Dockyard for a cost of £4,439. After a brief period of service in the
Irish Sea under the command of Captain John Aylmer, she returned to the English Channel where she remained throughout 1790 and early 1791. In mid-1791 she was under the command of Captain James Kineer, as the Navy relegated her to the status of an impressment vessel at Bristol, holding
press-ganged sailors aboard until they could be transferred to Navy vessels departing for foreign service. ==Capture and recapture==
