Meet Small Launcher SL1
Revolutionary three-stage smallsat launch vehicle powered by hybrid rocket technology. This system is designed to become the first European affordable hybrid launch vehicle capable of initially transporting satellites with payloads of up to 600 kg into dedicated Earth orbit.
About
Our orbital launch vehicle SL1 uses three stages optimized for low cost and affordability to deliver small satellites into orbit through a dedicated, customer-centric and highly responsive launch service. Based on hybrid rocket technology, where the solid fuel is already integrated into the combustion chamber, SL1 features a simplified launcher architecture with significantly fewer parts and components. This reduction in complexity enables rapid launch readiness, flexible scheduling, and short-notice mission execution, while also supporting an economically sustainable and environmentally responsible launch service.
