The third generation nuclear ballistic missile submarine for the French Navy

Florence Parly, the French Defense Minister, announced last Friday the launch of the third generation nuclear submarine program (submarine, submarine, ballistic, nuclear or SSBN) SNLE 3G (by Sous-Marin Nuclaire Lanceur d ‘ Third generation engines). for the French Navy Nationale. The announcement was made during the Minister’s visit to the Center for Expertise in Hydrodynamics of the Direction gnrale de l’armement (DGA).

This submarine program is a major challenge for the contractor Naval Group, a key industrial partner of the French sovereign. The first of these new submarines is scheduled to enter service in 2035. Three more submarines are being shipped at the rate of one in five years. Building an SSBN is one of the most complex industrial programs a business can face, much like expert building a spaceship. To do this, the Naval Group has the support of a broad network of up to 200 employees and suppliers from the French defense industry. The space for nuclear machines, for example, is the responsibility of TechnicAtome.

The Marine Nationale will have four new generation ballistic missile submarines, expected to be in service by 2090, and which are currently being phased out between 2030 and 2040. The SNLE 3G program is administered by the DGA, the Department of Defense. and the Navy. National and French Atomic Energy Commission (CEA) and alternative energies. Over the next 30 years, the program will generate 100 million man hours, including 15 million design hours and more than 80 million construction hours. In the case of the Naval Group, the Cherbourg plant provided 300 mechanical engineering workers and more than 2,000 construction workers. Take care of the platform (hull, superstructure and internal modules), the integration of the equipment on the platform, supplies and tests.

The Nantes-Indret facility will be responsible for the main engine room components and associated modules such as the engine. At the Angoulme-Ruelle plant, work is carried out on systems such as torpedo tubes, masts and the weapon management system. Combat and management systems are being developed in Ollioules, and work is being carried out in Bagneux and Lorient to manage the program and manufacture parts from composite materials. Ultimately, the Brest plant will be responsible for receiving and future maintenance of the submarine fleet. (Jos M Navarro Garca)
