Reaction Dynamics is reshaping access to space with a new generation of responsive launch vehicles
St-Hubert, Quebec
Founded in 2017, Reaction Dynamics (RDX) is a launch vehicle company built for the era of contested space. Our mission is to deliver rapid, routine, and sovereign access to orbit—on timelines aligned with defense and commercial needs. We’ve developed a next-generation hybrid propulsion architecture that breaks traditional trade-offs—combining simplicity, scalability, and responsiveness. Our vehicles are built to support the replenishment, augmentation, and reconstitution of satellite constellations for modern ISR, communications, and commercial applications. RDX operates at the intersection of national security, allied cooperation, and industrial resilience. We’re working closely with national security and space stakeholders across Canada, the U.S. Department of Defense, and NATO to offer a responsive launch capability ready for forward deployment. Because in the modern era of space, launch isn’t logistics—it’s strategy.
