Émeraude was a nuclear attack submarine from the first generation of attack submarines of the French Navy. Having been in service since 1988, she was retired in 2024.[4][5]
The boat was the fourth of the Rubis series. Between May 1994 and December 1995, the boat undertook a major refitting, which upgraded capabilities to the level of Améthyste.
On 30 March 1994, an accidental explosion occurred in the engine compartment while the boat was engaged in a naval exercise off Toulon.[6] The explosion killed ten men, including the commander, who were examining the turbo-alternator room. The boat returned to base under diesel and battery power.[7][8]

In June 2009, 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.[9]
In February 2021, the submarine successfully concluded a passage of the South China Sea.[10]
In October 2024, Émeraude departed Toulon for the final time, transitting to Cherbourg for her decommissioning but taking part in exercises with the Moroccan Navy enroute.[11] On 15 November 2024, the submarine arrived in Cherbourg to be decommissioned.[12]
