Indomptable ("Indomitable") was an Tonnant-class 80-gun ship of the line in the French Navy, laid down in 1788 and in active service from 1791. Engaged against the Royal Navy after 1794, she was damaged in the Battle of Trafalgar and wrecked near the Spanish city of Cadiz on 24 October 1805.
Indomptable was designed by naval engineer Jacques-Noël Sané and laid down in Brest in September 1788. She was launched on 20 December 1790, and completed in February 1791.
Her first engagement was on 29 May 1794 against HMS Barfleur and HMS Orion during the Glorious First of June campaign. Following the battle the dismasted Indomptable was towed back to Brest by Brutus.
In 1795, she served in the Mediterranean under Admiral François Joseph Bouvet and took part in the landing attempt in Ireland planned by General Louis Lazare Hoche. In 1801, she was engaged in the campaign in Egypt, but was unable to break the English blockade and stayed in Toulon. Other elements of the fleet managed to reach Elba.
L'Indomptable was a Le Fantasque-class large destroyer (French: contre-torpilleur) of the French Navy, which served in World War II. Launched during the 1930s, the ship served in the Mediterranean and, very shortly, in northern Europe.
After being launched on 8 December 1933, L'Indomptable entered into service in Spring 1936. She served with the Mediterranean fleet based in Toulon before transferring to the Atlantic Fleet, where the Le Fantasque-class destroyers were assigned to the Force de Raid when war was declared. She was scuttled in Toulon on 27 November 1942 along with the major part of the French fleet.
