Our reliability, your high standards !
In a rapidly evolving global geopolitical landscape, the reliability of military equipment is a prerequisite for operational success. Drawing on 40 years of experience—including 15 years serving the defense sector—OTS has established itself as a key strategic partner for French and international clients.
Based in Brittany, our company embodies the excellence of “Made in France” manufacturing, ensuring the national sovereignty essential to the security and defense industries. We support our clients throughout the process—from initial design via our engineering department to medium-batch production—by delivering high-precision industrial technical solutions.
Managing complex projects in the defense sector requires seamless coordination. OTS simplifies your supply chain by acting as a single point of contact. We manage the entire production cycle—from engineering design to final output—offering a comprehensive solution that combines expertise in:
This vertical integration ensures full traceability, reduced production lead times, and rigorous cost control.
The quality of our assemblies is certified under the ISO 3834 welding standard, attesting to the rigor of our processes and the competence of our operators. Furthermore, we are certified to apply defense-grade coatings. We have mastered the most demanding specialized coatings—such as the renowned “Brun Terre de France” (French Earth Brown), NATO Green, and other shades—thereby ensuring compliance with standards for camouflage and resistance to harsh environments.
