The French government has embarked on a strategic new program to cultivate its own space-based synthetic aperture radar (SAR) capability. This ambitious initiative, contracted with the US startup Loft Orbital, alongside esteemed European partners Thales Alenia Space and TEKEVER France, signals a determined push towards national space autonomy. The collaboration underscores France’s commitment to securing critical technological control in the orbital domain.
DESIR: A Strategic Pivot Towards Sovereign Imaging
Signed by the French military’s acquisition unit, the Directorate General of Armaments (DGA), and the national space agency, CNES, the new contract will see the development and launch of a single demonstration satellite. For decades, France has relied on all-weather, day-and-night SAR imagery from Germany’s now-aging SAR-Lupe constellation, in exchange for providing visual imagery from its own Helios electro-optical satellites. This new undertaking, dubbed DESIR (Démonstrateur des Éléments Souverains d’Imagerie Radar/Sovereign Radar Imaging Elements Demonstration), represents a fundamental shift in strategy for Paris, establishing a French government-owned and -operated SAR satellite network. This effort is heralded as a major milestone in developing a national radar imaging value chain, deemed critical for both the armed forces and France’s strategic independence.
A Consortium of Innovation: Powering the Future of French Space
Loft Orbital, headquartered in San Francisco with a significant operational presence in Toulouse, France, serves as the prime contractor and leader of this trilateral consortium. Thales Alenia Space and TEKEVER France are actively co-designing the SAR sensor payload. Thales Alenia Space’s involvement will leverage its extensive capabilities in Earth observation instruments and ground segments, with expert teams contributing to the imaging radar’s development and drawing on established expertise from export programs for the user ground segment. The satellite, built upon Loft’s Longbow platform, is projected for a 2029 launch. It is designed to be more than a mere prototype, functioning as a demonstrator capable of providing operational capability to the French government for over two years.
Macron’s Vision: A Resilient and Independent Space Frontier
This initiative aligns seamlessly with French President Emmanuel Macron’s broader vision for space. In November, he announced a planned increase of €4.2 billion in military space spending between 2026 and 2030, coupled with a new national space policy emphatically focused on achieving „sovereignty and independence” in the domain. Through the DESIR program, France is not only modernizing its observational capabilities but also reasserting its position as a key player in the global space arena, with an unwavering focus on controlling its own strategic assets.
