She made one voyage as a whaler in the Southern Whale Fishery, and then participated as a transport in a naval expedition.

On 17 August 1995 three French privateers of 18, 16, and 14 guns, stopped Juno, Baxter, master, 25 leagues west of the Naze of Norway.

Juno was reported to have been in the Pacific in November 1803, at the Galapagos Islands in January 1804, and off the coast of Peru in April.

After the invasion, the victualer Juno, of 239 tons (bm), sailed on 11 March 1806 to Plettenberg Bay to load with timber.

[6] Alternatively, she may have been the whaler Juno, Goodspeed, master, that Lloyd's List reported in August 1809 had been condemned at the Cape of Good Hope and broken up.
