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 supersede 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 Frappe. These ships are the most expensive submarines ever produced costing more than €9 billion. Their home port is Île Longue, Brest, Western Brittany.
