Triomphant-class Nuclear Ballistic Missile Submarine

The Triomphant-class ballistic missile submarines of the French Navy is the active 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 €4 billion. Their home port is Île Longue, Brest, Western Brittany.
