French eVTOL aircraft developer Ascendance plans to demonstrate its Sterna hybrid-electric propulsion system on a fixed-wing drone as part of a government-backed initiative to modernize observation capabilities at missile testing facilities.

The Direction Générale de l'Armement (DGA), France's defense procurement agency, is funding the project. It intends to use the hybrid-electric demonstrator vehicle for maritime surveillance and monitoring of tests launched by DGA Essais de Missiles (the DGA Missile Testing Center).
