Europe develops its own reusable VORTEX spaceplane reminiscent of NASA shuttles

Europe is moving to reduce its dependence on foreign launch systems with a new reusable spaceplane project called VORTEX. Led by France and Germany, the program aims to create a vehicle capable of transporting cargo, and later astronauts, to low Earth orbit and back.

The design clearly echoes the form of NASA’s retired Space Shuttle and modern concepts like Dream Chaser, but is tailored to European requirements and strategic ambitions. A first demonstrator vehicle is expected to be tested before the end of 2027.

VORTEX: a European answer to reusable space transport

VORTEX, short for “Véhicule Orbital Réutilisable de Transport et d’Exploration” (Reusable Orbital Vehicle for Transport and Exploration), was officially presented during last year’s Paris Air Show in France. The project is intended as a key element in Europe’s push to gain more autonomy in space operations, after years of lagging behind the United States and China in the new wave of spaceflight.

The long-term goal is to field a reusable spaceplane that can place payloads into low Earth orbit, conduct autonomous missions in space, and eventually transport people. In its final form, VORTEX is envisioned not only as a cargo carrier but also as a platform for crewed flights.

Industrial partnership led by Dassault and OHB

The program is being developed by a dedicated industrial consortium in which France’s Dassault Aviation plays a central role. Dassault is responsible for the spaceplane’s overall design and acts as the main system integrator.

More recently, German space company OHB has joined the effort. OHB plans to build a service module for one of the planned versions of the vehicle, known as VORTEX-S. This variant is described as autonomous but not yet full-scale, intended as an intermediate step between the demonstrator and a fully operational system.

Design echoes NASA’s shuttle and Dream Chaser

Concept images of VORTEX immediately bring to mind NASA’s Space Shuttle. The European design features a similar winged orbital vehicle with a cargo bay positioned in the central fuselage. The bay is shown with a two-part hatch that opens sideways, recalling the shuttle’s payload doors.

In overall proportions and mission concept, VORTEX also strongly resembles the Dream Chaser spaceplane developed by US company Sierra Space. Dream Chaser is designed to deliver cargo to low Earth orbit and return to runway landings, and was originally proposed for flights to the International Space Station. With the ISS expected to be deorbited in coming years, both American and European teams will likely look for broader uses of such vehicles.

From demonstrator to operational spaceplane

The VORTEX development roadmap is divided into several stages. The first step is a demonstrator called VORTEX-D, a scaled-down vehicle built at roughly one-third of the size of the planned operational craft. This smaller version is intended primarily to validate key technologies, aerodynamics, and re-entry and landing techniques.

According to the current schedule, VORTEX-D should be completed in 2026, with its inaugural flight targeted before the end of 2027, assuming the timeline is not disrupted. The demonstrator will be launched atop Rocket Lab’s Electron rocket, a small launcher capable of placing payloads of up to around 300 kilograms into orbit. That constraint means the test vehicle will be relatively compact compared to a full-scale spaceplane.

Additional variants, including the autonomous VORTEX-S and an eventual crew-capable configuration, are planned as the program matures, but detailed specifications have not yet been publicly disclosed.

How VORTEX fits into Europe’s strategic space plans

The European Space Agency (ESA) has expressed interest in the Franco-German initiative. VORTEX aligns with ESA’s strategic objective of creating an independent European space transport capability, including systems that can both reach orbit and return safely to Earth.

In 2023, ESA launched the LEO Cargo Return Service initiative, aimed at developing a European system that can deliver cargo to low Earth orbit and bring it back down. A reusable spaceplane like VORTEX fits directly into this framework. Information published by Dassault Aviation indicates that the vehicle is being designed with multiple roles in mind, including orbital logistics, technology demonstration, and broader support for European space infrastructure.

Military planners are also watching the project closely. As security strategies increasingly factor in space-based assets, European governments are looking for dedicated systems that reduce dependence on launchers and spacecraft operated by non-European powers.

Global race in reusable spaceplanes

Europe’s VORTEX will not enter an empty field. The United States and China are already testing their own reusable orbital vehicles with broadly similar concepts.

The best-known example is the US X-37B spaceplane, which has been flying experimental missions for more than a decade. The most recent, eighth mission began in the summer of 2025, when the uncrewed vehicle was launched back into orbit. X-37B strongly resembles a scaled-down Space Shuttle, complete with a small cargo bay, and its flights are used to test various technologies and experiments. Some of these activities remain classified and are widely believed to serve defense-related purposes. During its OTV-6 mission, X-37B stayed in orbit for a record 908 days.

China operates a similar reusable spaceplane known as Shenlong, meaning “Divine Dragon.” The vehicle has already flown multiple orbital missions and, like its American counterpart, is designed for repeated use. Chinese authorities disclose few details about the program, but US analysts suspect it is also being used to trial technologies with potential military applications.

Against this backdrop, VORTEX represents Europe’s effort to secure its own place in the emerging class of reusable spaceplanes. If the demonstrator flight in 2027 proceeds as planned, it will mark an important milestone in building a home-grown, runway-landing orbital vehicle for future European missions.
