About us
Founded in 1989 by Charles CASANOVA, ATERMES initially focused on industrial cooperation, combining expertise in mechanical, electronic, optronic and software design.
Driven by its founder’s vision, the company quickly developed its sales activities in export markets. Today, under the leadership of Lionel THOMAS and with the continued support of Charles CASANOVA, ATERMES operates across several locations: Montigny-le-Bretonneux, its engineering center in France; Salbris, its manufacturing center in France; Lyon, its software and artificial intelligence laboratory in France; and Dubai, its MENA operations headquarters in the United Arab Emirates.
ATERMES continues to develop industrial cooperation, mainly for major European defence and security companies, placing high-tech applications at the heart of its design approach.
The company remains committed to its original values: the highest level of quality in every part it designs or manufactures, a daily commitment to customer satisfaction, and the spirit of a traditional French family-owned company with strong consideration for its workforce.
Today, ATERMES’ offer is built around three pillars: industrial cooperation from upstream design through to manufacturing and deployment; a wide range of high-tech products based on optronics, surveillance and security systems, supported by worldwide services; and global MRO services for both ATERMES and client products, from legacy equipment to advanced high-tech systems.
Our history
In 1989, Charles CASANOVA set up ATERMES (Applications Techniques Études Réalisations Mécaniques Électroniques Systèmes), a small subcontracting and engineering company specializing in electronic and mechanical wiring for the defense industry, in a garage in Bagneux in the Paris region.

This new site close to major decision-makers enables the development of high value-added studies and designs.




ATERMES continues to supply equipment and systems, and is starting to develop new products such as NOCTUA (gyro-stabilized optronic head), ATLANTIS (drone interface) and A-TOM500, an automatic laser bird deterrent system for airports.

French investment fund LFPI has acquired a stake in ATERMES, facilitating access to new export markets and providing the company with external growth opportunities to propel ATERMES into a new dimension.

Launch of ASOS (ATERMES Operational Surveillance Solution), a modular border surveillance concept tailored to customers’ requirements, incorporating ATERMES' new optronic solutions such as SURICATE (optronic radar).

Since February 9, 2023, ATERMES has been reinforcing its production capacity by combining the resources of MSB INDUSTRIES, a company fully integrated within ATERMES. All MSB INDUSTRIES' activities have now been transferred to our Salbris industrial site, strengthening our skills and resources, and enabling us to extend our range of services to all MSB INDUSTRIES and ATERMES customers.
