On Tuesday, September 23, 2025, Dassault Aviation officially inaugurated its new production facility in Cergy, on the northwestern outskirts of Paris. This is the French manufacturer’s first new factory since the 1970s. The ceremony, led by Chairman and CEO Eric Trappier, gathered numerous employees, government and local officials, as well as industry leaders.
Among the attendees were Philippe Court, Prefect of the Val d’Oise department, Valérie Pécresse, President of the Paris Regional Council, Marie Christine Cavecchi, President of the Val d’Oise Departmental Council, and Jean-Paul Jardon, Mayor of Cergy. Military representatives and regional industry partners were also present.
“This is Dassault Aviation’s first new production site in more than half a century and a strong signal to the entire aerospace sector. France has unique expertise that we must preserve and develop. This is a matter of sovereignty, but also an economic and social imperative, since reindustrialization and job creation are key to our growth,” Trappier stated.
Construction of the new complex began in 2021, and operations started in the summer of 2024, taking over activities from the aging Argenteuil plant. In Cergy, work includes the assembly of fuselage panels and smaller parts for Falcon business jets and Rafale fighter aircraft, assembly of forward fuselages, outfitting Rafale fuselages with electrical, fuel, hydraulic, and air systems, as well as the production of metal tubing.
The site covers 110,760 square meters, with nearly 40,000 dedicated to production halls. The facility is equipped with rooftop solar panels, an innovative ventilation system, and smart lighting. Green spaces are integrated into the complex, which employs more than 600 engineers, technicians, and skilled workers, most of them transferred from Argenteuil.
The project was launched in 2019, with construction completed and equipment transferred in early 2025. Cergy has taken over all functions of the old site except for the production of smaller basic parts, which has been relocated to Seclin.
Dassault Aviation, employing 14,600 people, has delivered more than 10,000 military and civil aircraft over the past century, including 2,700 Falcons in 90 countries worldwide. In 2024, the company generated revenues of €6.2 billion.
