The Émeraude is a nuclear submarine from the first generation of attack submarines by the French Navy.

She is the fourth of the Rubis series. Between May 1994 and December 1995, she undertook a major refitting which upgraded her to the level of the Améthyste.

On 30 March 1994, an accidental explosion occurred in the engine compartment while the boat was engaged in a naval exercise off Toulon.[2] The explosion killed ten men, including the commander, who were examining the turbo-alternator room. She returned to base under diesel and battery power.[3][4]

In June 2009, the Émeraude was sent to the mid Atlantic to aid in the search for the flight data recorder and cockpit voice recorder from the ill-fated Air France Flight 447.[5]
