French ship Foudroyant (1799)

The Foudroyant ("Lightning") was a Tonnant-class ship of the line 80-gun ship of the line of the French Navy.

She was started in Rochefort from 1793, and renamed to Dix-huit fructidor in 1798 in honour of the Coup of 18 fructidor an V, as she was still on keel but reverted to Foudroyant in February 1800.

She took part in cruises in the Caribbean under Villaret de Joyeuse.

On 15 September 1806, while under jury rig some 15 mi off Havana, she encountered HMS Anson (1781), under Captain Charles Lydiard. Anson, mistakenly believing Foudroyant distressed, attacked, and was driven off.

She took part in the Battle of the Basque Roads.

She was eventually broken up in 1834.
