Aviation News – Dassault Aviation and OHB have officially submitted a joint proposal to the European Space Agency (ESA) to develop VORTEX-S, a multipurpose reusable spaceplane. The project aims to secure European sovereignty in space by providing a flexible vehicle for station logistics and autonomous orbital operations.
The partnership, announced on May 11, 2026, positions Dassault Aviation as the prime architect and global integrator, leveraging its extensive history in supersonic and hypersonic flight. German space giant OHB will serve as the lead architect for the service module, forming the industrial core of what is expected to be a wide-reaching European consortium.
The project comes as the European Space Agency seeks to close the gap in reusable transportation, a field currently dominated by private American firms and state-funded programs in China. The VORTEX-S is designed to meet this demand by offering a dual-use platform capable of serving both scientific research and high-priority governmental missions.
Technically, the VORTEX-S operates as a hybrid between a traditional spacecraft and a high-performance jet. It is designed for round-transport to low-Earth orbit, featuring a large payload bay for cargo and the ability to perform autonomous orbital free-flyer missions. Unlike traditional capsules, its aerodynamic design allows for controlled atmospheric reentry and a horizontal runway landing, significantly reducing turnaround times and operational costs.
“With the Vortex-S proposal to ESA, we aim to strengthen Europe’s space capabilities. Our German friends at OHB are natural partners to participate in this project, bringing their remarkable expertise,” declared Éric Trappier, Chairman and CEO of Dassault Aviation.
The successful development of VORTEX-S would mark a turning point for the continent’s space mobility, offering a level of mission flexibility previously unavailable to European operators. By consolidating industrial expertise across borders, the project seeks to establish a permanent, reusable bridge between Earth and orbital infrastructure.
The collaboration represents a strategic push toward strategic autonomy in the increasingly competitive space sector. By integrating advanced aeronautics with reliable satellite technology, the partners are creating a roadmap for sustainable space access. If approved by ESA, the VORTEX-S could become the cornerstone of European orbital logistics for the next decade.
