stops its activities in the area of maritime renewable energy. Naval defence Naval Group designs, develops and manages the operational readiness of surface and underwater naval systems, and of their associated systems and infrastructures. As a project manager and integrator of armed vessels, Naval Group intervenes all along the value chain, from strategic programme planning, to design, construction and the management of operational readiness. The group works with the French navy and other navies, for conventional products, and with the authorisation of the French government. It also offers its military expertise to the French Air Force to design automated navigation and combat systems, and to renovate aircraft. Surface naval systems Aircraft carriers: Helicopter carriers: LHD Multi-mission frigates: FREMM-class frigates & Frégate de défense et d'intervention-class frigates (planned); La Fayette-class frigate Multi-mission frigates: Design of Second Generation Patrol Vessel for the Royal Malaysian Navy, based on the Air defence frigates: s Medium-tonnage vessels: s Construction of aerial drones for the navy Submarines and underwater weapons Conventional submarines: , and Nuclear submarines: ballistic missile nuclear submarines and Nuclear submarines: nuclear attack submarines and Barracuda class Hybrid concepts: the company's Sous-Marin Experimental (SMX) series explores advanced concepts for submarine warfare. One in the series—the SMX-25—was designed to arrive in theatre rapidly through high surface speed and then operate as normal underwater. Suffren class: Nuclear submarines: nuclear attack submarines Rubis class and Barracuda class : Barracuda (class Suffren) F21 heavy-weight torpedoes MU90 light-weight torpedoes Energy and marine infrastructures The group collaborates with EDF, the CEA and AREVA in the construction of EPR power plants and the maintenance of nuclear power plants. Naval Group also builds thermal electric power plants and naval bases. The group designed the electric power plants in Mayotte, La Réunion and Saint-Pierre-et-Miquelon. Since 2008, they have been studying a concept of a small nuclear power plant (50 to 250 MWe) named Flexblue. The project was put on hold in 2014. Naval Group was investing in four renewable marine technologies: wave energy, marine current turbines, ocean thermal energy conversion (OTEC), and floating wind turbines. Naval created Naval Energies in 2017. Since it gained control of the Irish company OpenHydro in 2013, Naval Group has been able to progress from the research and development phase to industrial production. In 2021, Naval Group stopped the Naval Energies activities. Corporate responsibility Naval Group operates several programmes to promote training and professional integration. The group has
