Naval Group designs, develops, manufactures and maintains in service equipment for submarines and surface ships around the world in order to guarantee and enhance ship performance.

The highly technical nature and performance of Naval Group’s equipment provides French and foreign navies with a strategic and decisive operational edge.

Naval Group’s two equipment manufacturer sites at Angoulême-Ruelle and Nantes-Indret, offer the most competitive products.

Our equipment offer


    The Sylver® vertical missile launching system range enables the firing of surface- to-air missiles or naval cruise missiles.
    Naval Group has sold over 200 Sylver® around the world.

    Vertical missile launching systems


    The Samahé® helicopter handling system enables helicopters to be transferred in complete safety between the flight deck and the hangar and vice versa, all in rough seas. The Samahé® range is adapted to all naval helicopters of up to 16 tons.

    Landing grids

    Helicopter landing grids enable rapid take-off and landing of helicopters and drones in complete safety and in difficult sea conditions, while also respecting NATO standards.

    Hoistable masts

    The masts measure up to 14 meters and are strategic elements of the combat system, raising the submarine’s sensors out of the water when it is at periscope depth. They also act as a snorting mast, keeping the boat’s diesel engines supplied with air.


    Shaft lines

    Shaft lines are a part of the propulsion system and form the link between the motor and the thruster.
    Naval Group’s industrial capacity enables machining work on shafts measuring up to 25 metres.

    Submarine weapon-launching tubes

    Submarine weapon-launching tubes are compatible with all types of weapons (torpedoes, missiles, mines) in a NATO format. The highest levels of security are given to these essential mechanical components that penetrate the pressure hull and form an integral part of diving safety.

    Tube lance torpille

    Surface ship torpedo-launching tubes

    Torpedo-launching tubes are capable of launching light torpedoes respecting the NATO standard from surface ships and are available in several configurations (two or three tubes).


    Gearboxes allow speed reduction on motors, whilst still respecting the requirements for combat ships concerning shock resistance, acoustic discretion, vibrations, compactness, reliability and minimum maintenance.


    Seawater exchangers guarantee a high level of performance for onboard cooling systems such as the propulsion and electricity production systems.


Barracuda, an example of a highly equipped class of submarine

It would be difficult to provide an exhaustive list of all the equipment on the Barracuda-class submarines making them the formidable and discreet warships that they are. This new French nuclear attack submarine (SSN) is equipped with an architecture enabling easy, fast and accurate manoeuvring. Its stealth is increased tenfold thus diminishing its trace. Developed by Thales, its sonar suite contains several acoustic sensors, each with a specific spatial and frequency coverage. Lastly, its flank array sonar considerably increases its listening capabilities. Ultra-precise digital sensors, new-generation antennae, optronic masts and mine and obstacle avoidance sonar complete the equipment set for the French Navy’s new SSN.
