HMS Thunderer was a 74-gun third-rate ship of the line of the Royal Navy, launched on 13 November 1783 by the Wells brothers' shipyard in Rotherhithe. Constructed as a ship of the line, her design accommodated three gun decks and a broad, formidable hull capable of carrying a substantial armament. After her launch, she was laid up until 1792, undergoing a 'Middling Repair' before entering active service in 1793. Throughout her career, Thunderer participated in notable naval engagements during the French Revolutionary and Napoleonic Wars. She fought at the Glorious First of June in 1794 under Captain Albemarle Bertie, and later served in the West Indies from 1796 to 1801, where she played a role in the Battle of Jean-Rabel. During this period, she was involved in the capture of the French frigate Harmonie, which her crew helped force to scuttle to prevent capture. Thunderer was also active in pursuit and capture operations, including the chase of French frigates and privateers in 1800, notably capturing the 18-gun French brig Éveillé after a long chase. In 1799, she was involved in the detention of the schooner Pegasus, which was found to be carrying slaves under false papers. The ship also rescued the crew of HMS Diligence after it struck a reef off Cuba. Recommissioned in 1803 under Captain William Bedford, Thunderer captured the French vessel Rosamond and the privateer brig Venus, a well-armed vessel with a crew of 150. Her service culminated at the Battle of Cape Finisterre in 1805, and she played a key role in signaling during the Battle of Trafalgar, where her First Lieutenant, John Stockham, was present. She also detained the Ragusan ship Nemesis during this period. Thunderer served in the Dardanelles Operation in 1807 and participated in the Alexandria expedition before being decommissioned in 1808. She was broken up in 1814, with some of her timbers reputedly reused in local constructions. Her active service and participation in major naval battles mark her as a significant vessel of the Royal Navy during the late 18th and early 19th centuries.
