French lawmakers have proposed allocating a symbolic €1 for Dassault Aviation’s VORTEX spaceplane programme in an effort to compel the government to clarify its financial commitments to the project.
In a 16 October amendment to France’s proposed 2027 budget, 71 MPs from the La France Insoumise party proposed creating a dedicated budget line for VORTEX under the country’s defence spending plans. The amendment would transfer a symbolic €1 from an existing defence support programme to the new budget line, as French parliamentary budget rules allow MPs to reallocate funding between programmes but not increase overall spending.
Rather than seeking to provide meaningful funding for VORTEX, the MPs are using the symbolic allocation to compel the government to explain how the country will fund the project and clarify the extent of Germany’s involvement.
“Its purpose is to question the government about the programme’s absence from the proposed 2027 budget and to formally establish the objective of developing a French reusable spaceplane capability within the state budget.”
In June 2025, the French Ministry of the Armed Forces signed an agreement with Dassault Aviation to support the development of the VORTEX-D demonstrator. President Emmanuel Macron subsequently announced broader support for the VORTEX programme on 10 September 2026 during an international space summit in Paris.
Despite this public support and the inclusion of VORTEX among projects earmarked for preliminary defence research funding in 2026, the MPs argue that the government’s proposed 2027 defence budget provides little clarity on its financial commitments to the programme.
The MPs also raised questions about Germany’s potential involvement in VORTEX, particularly following the collapse of the Franco-German Future Combat Air System (SCAF) fighter aircraft programme in June 2026. The implication is that the same disputes that derailed SCAF could also threaten the future of VORTEX.
Germany’s involvement in the project is based on a partnership announced in May 2026 between Dassault Aviation and the German space company OHB to propose the VORTEX-S spaceplane to the European Space Agency. Under the proposed arrangement, Dassault would lead the development of the spacecraft, while OHB would be responsible for its service module.
