Editor’s Note
After 36 years of service, the French nuclear attack submarine Emeraude has reached its final port. This article marks the end of its long operational journey.

After 36 years of active service, the nuclear attack submarine (SNA) Emeraude arrived on Friday, November 15, 2024, at the naval base in Cherbourg-en-Cotentin (Manche) to be decommissioned. It had entered active service in September 1988.

The Emeraude, 74 meters long with a crew of 70 sailors, is the fourth Rubis-class nuclear attack submarine (SNA) to be decommissioned, following the Saphir in 2019, the Rubis in 2022, and the Casabianca in 2023.
All Rubis-type SNAs are to be replaced by new-generation Suffren-class SNAs by 2030.
Equipped with nuclear propulsion, SNAs are tasked with protecting strategic assets such as the aircraft carrier Charles-de-Gaulle or the ballistic missile submarines (SNLE), which carry nuclear missiles. They also gather intelligence.
On March 30, 1994, an accident in the engine compartment caused the death of ten sailors, including the commander, during a dive off Toulon.
