Her war service in the American War of Independence was conducted with Rodney's fleet in the Caribbean, where she served in the battles off Grenada in 1779, Martinique in 1780 and the Saintes in 1782. Her duties during the Napoleonic Wars mainly consisted of blockade duties off the French coast, but between 1798 and 1800, the ship had received a complete overhaul designed to extend her service life and improve her ability at performing the close blockade.
