HMS Hero was a notable 74-gun third-rate ship of the line of the Royal Navy, launched on 28 March 1759 and designed by Sir Thomas Slade. Built at Plymouth Dockyard by Thomas Bucknall, she was unique in her draught, being the only ship constructed to her specific design. As a third-rate ship, she balanced firepower and maneuverability, making her a versatile component of the Royal Navy's fleet during the mid-18th century. Her early service included notable engagements, such as her involvement in the capture of the French East Indiaman Bertin on 3 April 1761, alongside HMS Venus. The captured vessel was subsequently purchased by the Royal Navy and commissioned as the third-rate Belleisle. From 1763 to 1767, HMS Hero was commanded by Captain Paul Ourry, reflecting her active role in naval operations during this period. HMS Hero participated in significant naval battles during the American Revolutionary War. She fought in the Battle of Porto Praya on 16 April 1781, a naval engagement between a British squadron under Commodore George Johnstone and a French squadron commanded by the Bailli de Suffren. Later, under Captain Theophilus Jones, she took part in the Battle of Cuddalore in 1783, contributing to Britain's military efforts in the conflict. In 1793, HMS Hero was converted to a prison ship, a common fate for aging warships no longer suited for battle. She served in this capacity until her decommissioning and was eventually broken up in 1810. Her service history reflects the typical lifecycle of 18th-century ships of the line, from active combatant to auxiliary role, marking her as a vessel of maritime and military significance during her era.
