Underwater weapons

Naval Group designs, builds and provides in-service support for underwater weapons systems and anti-torpedo countermeasures to protect crews and ships.

Facing threats

Underwater threats are rapidly growing in all every ocean around the globe, whether the Atlantic or the Mediterranean, the Indian Ocean or the South Pacific.

There has been a recent escalation in the activities of Chinese, Russian and American navies, naval defence budgets have been increased, as has the construction of submarines of various sizes (mini-subs, coastal patrol submarines, conventional or nuclear propulsion) with a view to extending existing naval fleets.

This means that hundreds of submarines are navigating the world’s oceans at any given time, keeping nations on alert mode, all determined to preserve their sovereignty and interests. Underwater weapons are therefore a key element in a nation’s naval strategy. Naval Group possesses unique know-how in the design and manufacture of torpedoes and anti-torpedo countermeasures. To meet the demand for innovative, powerful and intelligent means to lead underwater warfare, Naval Group offers its customer navies a product capable of meeting the challenges of the stakes at hand.

Our underwater weapons offer

F21®

The F21® is the most advanced, enduring, rapid and reliable submarine torpedo of its generation. Extremely versatile, the F21® was designed from the outset for long-range engagements and can take on targets of all sizes in highly complex operational environments. Naval Group also supports navies with crew training, providing simulators and insights gained from live-fire exercises.

Canto®

The Canto® is the benchmark torpedo countermeasures system for surface ships and submarines. Based on a revolutionary confusion/dilution principle, the countermeasure generates hundreds of decoys, continuously and randomly reproduced, to overwhelm the data-processing systems of the most advanced torpedoes and drain their energy. The system takes effect as soon as it enters the water, providing 360-degree protection. Rapidly established as a global standard, Canto® now equips navies worldwide to safeguard their crews and fleets.

Naval Group possesses unique know-how in the design and manufacture of anti-torpedo countermeasures as well as their through-life support. Teams on the site of Saint-Tropez work over the complete life cycle of our products, from the R&D stage through to production and maintenance, including the development and qualification of our products on land and at sea. These trials are performed on site thanks to the range of testing means available and direct access to the sea.  Naval Group therefore delivers foreign navies the means to ensure their power at sea and contribute to the protection of ships and their crews. 

La Londe-les-Maures

The Var Est program aims to create a centre of excellence for drones, autonomous systems and underwater weapons on the site of Bormettes in La Londe-les-Maures. The program’s key challenges of the program involve reindustrialising a site that has not been used for more than 30 years, to the best environmental standards, strengthening our competitiveness, and improving our attractiveness and our collective efficiency.


This project will make it possible for teams from Naval Group, as well as those from our customer and partner companies, to come together on one and the same site. Beyond the transfer of teams and their activities, the project will allow us to develop our working methods in terms of both tertiary activities and production. The choice of architectural design reflects this desire by creating a modern industrial tool with a functional working environment, designed to promote creativity, collaboration, new ways of working and efficiency.
