The Triomphant class submarine is a ballistic missile submarine class of the French Navy. It consists 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 These four superseded the older Redoutable class, and they provide the ocean-based component (the Force océanique stratégique) of France's multi-discipline nuclear deterrent strike force, the Force de dissuasion ('deterrence force'). Their home port is Île Longue, Roadstead of Brest, Western Brittany.
