The Triomphant class of ballistic missile submarines of the French Navy is the active lead boat class of four boats that entered service in 1997, 1999, 2004, and 2010. These four superseded the older Redoutable class, and they provide the ocean-based component (the Force océanique stratégique) of France's nuclear deterrent strike force, the Force de dissuasion (deterrence force). Their home port is Île Longue, Roadstead of Brest, Western Brittany.
