DefenseDassault opens new production facility in Cergy, Paris region
Dassault Aviation inaugurated its new production facility in Cergy, north of Paris, on September 23. The event was attended by company President and CEO Éric Trappier, along with local and regional authorities.
The Cergy plant is the first new Dassault production site since the 1970s and replaces the company’s longstanding manufacturing operations at Argenteuil. The transition is part of a broader restructuring that began in 2019, with construction at Cergy starting in 2021 and completing in July 2024.
Since the summer of 2024, the facility has been operational, with the transfer of staff and equipment from Argenteuil continuing through January 2025. Over 600 engineers and technicians now work at the new location, most of them relocated from the former Argenteuil site.
“France possesses unique expertise that we must preserve and develop within our national territory. This is a question of sovereignty, which is particularly vital in the current context. It is also an economic and social imperative, to meet the challenge of reindustrializing our country and creating jobs,” said Éric Trappier.
Covering a total area of 110,760 square meters, the Cergy facility includes 39,700 square meters of production space. A notable feature is the fully solar-equipped roof, designed to lower energy consumption. The plant is also fitted with an advanced ventilation system and intelligent lighting, alongside integrated green spaces.
Production activities at Cergy focus on the assembly of skin panels and small parts for the Falcon business jets and Rafale fighter aircraft. Primary small-parts production has been transferred to Dassault’s Seclin plant, allowing Cergy to specialize in complex assemblies. The move aims to streamline manufacturing processes for both civil and military programs, including the ongoing Rafale orders and Falcon deliveries.
Dassault Aviation stated that the new facility is intended to support the company’s long-term industrial presence in France. The initiative is also positioned as part of wider efforts to boost reindustrialization and job creation in the country, while maintaining domestic aerospace expertise.
With the plant now fully operational, Dassault is expected to focus on ramping up production efficiency and integrating new manufacturing technologies. The company anticipates that the Cergy site will play a key role in future Falcon and Rafale programs, both for domestic and export markets.
