DCNS Research

Excellence in research technology

DCNS-Research-logo-fds-grisDCNS Research is the principal power behind the Group’s research and technological excellence. Created in 2011 to energise our innovation policy, the team today is made up of 150 engineers and technicians, located in the French cities of Nantes-Indret, Cherbourg, Bagneux and Toulon. DCNS Research works in three areas: expertise; stabilization of R&T through development of products and services; and research in DCNS’ strategic areas.

The Technology Readiness Level (TRL) rates the maturity of evolving technologies during development and before their application. Many enter on its lowest level, before any invention or even R&D. New concepts from DCNS Research however habitually skip these early stages, appearing first at Level 3 or 4, indicating that laboratory studies and certification have already been carried out, that the concept is valid and that the new technology will be applicable. Qualification during the final levels of TRL demonstrate, then prove that DCNS Research’s technology is applicable in its final form and will be operational under mission conditions.


The nine major fields of DCNS Research:

  • performance at sea
  • durability of in-service structures
  • on-board energy optimisation.
  • information dominance.
  • embedded and autonomous decision.
  • stealth and sensors integration.
  • environment integration and eco-friendliness.
  • secured complex systems.

A key player in DCNS’ influence

DCNS Research conceives and develops DCNS’ keys to its future success stories by accelerating transformation of fundamental technologies – such as processes, materials, algorithms, physical or digital models – into applications vital to the creation of new products and services.

DCNS Research also helps maintain and consolidate knowledge of today’s cutting-edge technologies within the ranks of DCNS experts, so these teams can continue their work: imagining the technological revolutions of tomorrow.

DCNS Research plays a key role in the Group’s growth internationally, through its efforts with scientific specialists across the globe in collaborative research programmes.

Skills recognised the world over and a reputation for producing reliable results have made DCNS Research teams sought after by individuals and companies outside the Group. Working internationally enhances their understanding of economic realities and time pressures affecting the world’s different markets.

DCNS Research is based on three naval research centers:

  • The Naval Structures and Materials Centre of Expertise (CESMAN) is the research centre for performance, resistance and dynamic behaviour of materials and structures at sea.
  • Sirehna is a SMB providing advanced R&D and multi-domain knowledge in naval hydrodynamics, control-command systems, experimental technologies, multi-disciplinary optimisation and power processes.
  • The Information and Signatures Management Centre of Excellence (CEMIS) is the research centre for information dominance, cyber defense, signatures management, stealth technologies and secured complex systems.

USV System-UnmanUSV System (Unmanned Surface Vehicule)

This multi-mission surface drone has an automatic obstacle detection and avoidance system and operates with autonomous decision. It also is equipped with other innovative functions for vehicle dynamics control, which are the fruit of Easy DP technology.




Easy DPEasy DP

This is the family of dynamic positioning systems (DP) and innovative autopiloting for all types of ships, both civil and military. Easy DP guarantees a ship’s position at a fixed point, maintains its course and its autopiloting.






Advanced Ship Mot

Advanced Ship Motion Stabilisation

Completing the range of stabilising systems available for military ships, including aircraft carriers on manoevres, these services are known on the international market for their unique functionalities.
