Project coordination and thruster unit engineering

ArianeGroup develops and supplies innovative and competitive solutions for civil and military space launchers. As lead contractor for the European Ariane 5 and Ariane 6 launcher families, as well as for the French oceanic deterrent force’s missiles and most innovative satellite equipment and subsystems. ArianeGroup is a joint venture equally owned by Airbus Defence and Space and Safran.

The staffs in charge of the proposal consist of experts in project management, marketing and engineering of space and orbital propulsion.

ArianeGroup is a leading manufacturer of orbital propulsion systems and components for spacecraft (S/C). Some 400+ S/C were equipped with ArianeGroup propulsion systems to date. ArianeGroup’s chemical, electrical and hybrid solutions cover the full orbital propulsion spectrum.
