Constructed by Naval Group, the leading European shipbuilder, the Duguay-Trouin is a part of France’s broader strategy to replace its aging Rubis-class submarines by 2030. Prior to its commissioning, the Duguay-Trouin was rigorously tested during sea trials which started in March 2023. These trials were essential to verify the submarine’s military characteristics, including performance, endurance, and the integration of various systems and equipment according to the Navy’s stringent requirements.
During these trials, the Duguay-Trouin demonstrated its operational capabilities in diverse environments, navigating both cold and warm waters, and even made a historical stop in Fort-de-France in March 2024—the first for a submarine of this class.
Naval Group’s role in this project highlights their expertise and leading-edge technologies in submarine construction, setting a new standard in naval warfare. The Duguay-Trouin is equipped with advanced features such as naval cruise missiles (MdCN) for precision ground strikes, and specialized support facilities for special forces, including a diver’s lockout chamber and a deck hangar.
