Naval & Maritime defence companies in France

ALSEAMAR develops underwater gliders, acoustic systems, radiocommunication and subsea solutions for naval defence, special forces and maritime operations.

Builds naval mine countermeasures systems, inertial navigation technology, autonomous maritime vessels and photonics instruments for defence, maritime and aerospace operators across 80+ countries.

UMIS (Unmanned MCM Integrated System)

A modular mine countermeasures system that combines aerial, surface and underwater unmanned vehicles — including inspector USVs, A9-M/A18-M AUVs, ROVs and towed synthetic aperture sonars — to detect, classify, identify and dispose of sea mines while keeping crews at safe distances. Managed through the Umisoft command and control software suite, UMIS can be deployed from ships, shorelines or a containerised format. It has been selected by the Belgian and Royal Dutch navies for the rMCM programme and by the Latvian Navy.

Naval Inertial Navigation Systems

A family of fibre optic gyroscope-based navigation and attitude systems for warships, submarines and unmanned underwater vehicles, including the Phins, Marins and Phins Compact ranges. The systems provide heading, roll, pitch and positioning data without relying on GNSS signals, with drift performance as low as 1 NM per 360 hours and qualifications to MIL-STD-810 and MIL-STD-461 standards. They cover submarines requiring acoustic signature minimisation through to compact INS units fitted in AUVs.

DriX Series Uncrewed Surface Vessels

A range of autonomous surface vessels designed for hydrographic survey, oceanographic research, subsea positioning and offshore operations, available in three models from 7.7 m to 15.75 m with ranges between 1,000 and 3,500 nautical miles. DriX vessels can operate beyond visual range via satellite and 4G/5G communications, support AUV and ROV deployment, and carry modular payloads. The fleet has accumulated over 250,000 hours at sea across 25+ countries.

Land and Air Inertial Navigation and Pointing Systems

The ADVANS series and related inertial measurement units provide navigation, pointing and stabilisation for land vehicles, artillery systems and airborne platforms operating in GNSS-denied or contested environments. The range covers vehicle navigation, weapon system pointing and stabilised optical and sensor platforms for ground forces.

Lumibird develops laser technologies and military laser rangefinders for defence, naval, aerospace, industrial and medical applications.

Operates a LEO satellite constellation that detects radio frequency signals from ships at sea, tracking dark vessels that disable AIS transponders to avoid detection.

Designs and manufactures waterproof, inflatable maritime mini-UAVs for ISR and search-and-rescue missions in naval, coastal and high-humidity environments where conventional drones cannot operate.

Builds swarms of micro autonomous underwater vehicles that map the water column acoustically across large areas. Its Lelantos loitering AUV and Seaker acoustic listening device have been trialled by the French Navy at Toulon.

ELWAVE designs, manufactures and sells electromagnetic detection, navigation and characterization systems based on innovative "electric sense" technology for underwater and industrial robotics.

HGH Infrared Systems designs electro-optical and infrared surveillance systems for defence, naval, security and critical-infrastructure missions.

Designs and manufactures underwater acoustic systems, autonomous underwater vehicles and mine countermeasures equipment for navies, research institutes and commercial maritime operators.

SEAir Platforms develops crewed and uncrewed foil-equipped maritime platforms for defence and security missions, focused on speed, stability and stealth.

Designs and manufactures mini-ROVs, USVs and underwater camera systems for marine inspection and defence. Twice awarded Best Defence SME by the French Ministry of Defence, with hull inspection and harbour security systems deployed across multiple countries.

Modular lithium battery manufacturer producing custom high-density packs for defence, robotics, and subsea applications. Supplies Thales Alenia Space and ALSEAMAR special forces underwater vehicles from its factory in Annonay, France.
