Dassault Aviation Begins Manufacturing Components for Vortex Spaceplane Demonstrator
Dassault Aviation has taken a new step in its reusable spaceplane program, Vortex, by starting production of key components for the demonstrator vehicle. The move signals growing momentum for the project, which the company hopes could achieve its first flight as early as 2028.
The Vortex-D demonstrator will be a compact spaceplane measuring around 4 meters in length and weighing roughly one metric ton. Designed to reach altitudes of approximately 100 km, it is expected to travel at hypersonic speeds between Mach 10 and Mach 12 during its mission. The demonstrator will allow Dassault to validate the system’s architecture and several critical technologies required for future operational vehicles.
Initial parts currently under construction will soon undergo high-temperature plasma torch testing at the Italian Aerospace Research Center (CIRA) in Capua, Italy. These tests are intended to evaluate different thermal protection solutions, including ceramic and ablative heat shield materials, and to better understand how heat loads will vary across the vehicle during atmospheric re-entry.
The spaceplane will incorporate five control surfaces and a structure primarily built from aluminum and titanium. According to Dassault, the design will feature a larger wingspan than Boeing’s X-37B, which should improve maneuverability and aerobraking capabilities during descent below approximately 120 km altitude.
The Vortex demonstrator is being developed through a joint investment between Dassault Aviation and the French government, with a combined budget of about €70 million, split equally between both parties. France has indicated that the vehicle could be launched aboard a Rocket Lab Electron rocket.
Assembly of the demonstrator is expected to take place at Dassault’s facility in Istres, France.
Although the program involves France’s defense procurement agency DGA, Dassault views Vortex as a dual-use platform. Beyond potential defense applications, such as rendezvous and proximity operations in orbit, the company believes the concept could serve the commercial space economy, particularly for returning high-value cargo from low Earth orbit. Future operational versions could land on conventional runways while exposing payloads to only 1.5 g, making them suitable for transporting sensitive products such as pharmaceuticals manufactured in microgravity.
The Vortex program follows a phased development roadmap. After the Vortex-D demonstrator, Dassault plans to develop Vortex-S, a more advanced smart free-flyer, followed by Vortex-C, an operational cargo vehicle capable of carrying around 2 tons of payload with a total system mass of 8–9 tons. In the longer term, the company is also considering a human-rated variant, referred to as Vortex-H.
Dassault has also indicated openness to international partnerships, potentially bringing in expertise from European partners such as Germany, echoing the collaborative model used for the Neuron unmanned combat air vehicle demonstrator.
