The Impétueux was a 74-gun ship of the line belonging to the Téméraire class, constructed for the French Navy during the late 18th century. Built at the Arsenal de Rochefort, she was laid down in 1786, launched on October 25, 1787, and completed in 1788. The vessel measured approximately 55.87 meters (183 feet 4 inches) in length, with a beam of 14.46 meters (47 feet 5 inches) and a depth of hold of 7.15 meters (23 feet 5 inches). She displaced around 3,069 tonneaux and had a tonnage of 1,537 port tonneaux. Her crew consisted of about 705 officers and ratings during wartime, and she was rigged with three masts, typical of ship rigged vessels of her class. The Impétueux's armament comprised a broad array of muzzle-loading, smoothbore guns. Her main battery on the lower gun deck included twenty-eight 36-pounder long guns, while the upper deck was equipped with thirty 18-pounder long guns, supplemented by an additional thirty 18-pounders. The quarterdeck and forecastle housed sixteen 8-pounder long guns. From 1787 onward, her armament was modified to include four 36-pounder obusiers on the poop deck, with some ships in her class also carrying twenty 8-pounders instead. During her service, the Impétueux participated notably in the Battle of the Glorious First of June in 1794. During this engagement, she became entangled with HMS Marlborough, suffering severe damage alongside her opponent, losing all three masts. The battle was intense, with heavy casualties, and Impétueux was rendered immobile. She was eventually seized by sailors from HMS Russell after the French ship was too damaged to move. The Royal Navy intended to incorporate her into their fleet as HMS Impetueux, but she was destroyed by an accidental fire at Portsmouth on August 24, 1794, before she could be commissioned. Her sister ship, America, was captured during the same battle and later renamed HMS Impetueux in 1795. The vessel's involvement in the battle and her subsequent destruction mark her as a notable, if short-lived, participant in the naval conflicts of her era.
