Ascendance and Delair Collaborate on Hybrid-Electric Observation Drone for French Defense
Ascendance and Delair have announced a partnership to develop a hybrid-electric observation drone, the DT46 Hybrid, aimed at enhancing the capabilities of the DGA Missile Testing Center in France. Funded by the Defense Innovation Agency, the project focuses on creating a drone that combines Delair's DT46 model with Ascendance's STERNA propulsion system, improving endurance, flexibility, and environmental benefits for military and civilian applications.

Ascendance and Delair are collaborating to develop the DT46 Hybrid observation drone, integrating Delair's DT46 model with Ascendance's hybrid propulsion technology, STERNA. This initiative, funded by the Defense Innovation Agency, addresses the modernization of the DGA Missile Testing Center's capabilities.
The drone can operate over 5.5 hours in VTOL mode, switch between hover and airborne modes, and alternate between thermal and electric modes for various missions. Flight tests have begun in Toulouse, with qualifying flights planned in Biscarrosse, France, in spring 2025. The project aims to provide economic and environmental benefits while enhancing long-distance mission capabilities.
