Our history
Depuis 1975, ARCYS évolue au cœur des enjeux technologiques français en alliant fiabilité, innovation et engagement industriel. Une aventure humaine et technique qui nous a menés du spatial à la Défense, du nucléaire à la mobilité durable.

A trajectory anchored in high standards
For more than 50 years, ARCYS has established itself as a key player in safety electronics and instrumentation for harsh environments.
From its origins in major aeronautical and military programs to its current role in nuclear propulsion, civil nuclear power, and transportation, our company has adapted, strengthened, and modernized to meet increasingly critical challenges.
"We are proud to contribute to large-scale programs that serve national sovereignty and the energy transition."
Philippe Léon, President of ARCYS
A company on the move
Our history is also one of continuous transformation: name changes, changes in shareholder structure, market expansion, growth in staff numbers, and modernization of tools.
Today, ARCYS brings together nearly 200 employees in Blagnac, working on major programs such as:
• The next-generation aircraft carrier (PA-Ng)
• The Barracuda and SSBN 3G submarines
• The EPR and SMR reactors
• The Paris metro and on-board rail solutions
And tomorrow? Our ambitions continue, supported by a strategic roadmap, active recruitment and a policy of continuous innovation.
A collective human adventure
