Key Takeaways
- The Hydis project has finalized a solid-propellant rocket motor concept to counter hypersonic threats.
- The European Defence Fund has allocated €100 million for the interceptor, with competing project Hydef already receiving €100 million in funding.
- Hydis aims to advance critical technologies to Technology Readiness Level 3, focusing on defeating various hypersonic threats.
Advancements in European Hypersonic Defense
The Hydis project, aimed at developing a European interceptor against hypersonic threats, has successfully established a solid-propellant rocket motor concept endorsed by MBDA, Europe’s leading missile manufacturer. The final concept review was validated by the program’s steering committee, marking a significant advancement in the project.
As the program enters its final year, focus will shift towards enhancing critical technologies to achieve at least Technology Readiness Level 3, which indicates an experimental proof of concept. This initiative is one of two ongoing European efforts to create countermeasures against hypersonic threats, in competition with the Hydef program spearheaded by Diehl Defence in Germany, coordinated alongside Spain’s SMS Sistemas de Misiles de España.
The European Defence Fund (EDF) has pledged €100 million for the development of an endo-atmospheric interceptor as part of its 2026 program, with only one of the ongoing proposals expected to receive funding. A statement from OCCAR highlighted the successful completion of the final concept review as a pivotal milestone for developing Europe’s capabilities against hypersonic threats.
The validated interceptor concept, proposed by the Hydis industrial consortium, is intended to target a range of threats, including hypersonic glide vehicles, cruise missiles, and maneuvering ballistic missiles. This assessment was informed by threat models developed by Italy’s Centro Italiano di Ricerca Aerospaziale, France’s Onera, and the Dutch technology institute TNO.
The review mainly concentrated on the terminal interception phase, with OCCAR noting that the program is now positioned to move forward with a “clear path” toward technological maturation. Contributions from various participants in the consortium include Avio, responsible for the solid rocket motor’s architecture, and Roxel, which worked on control mechanisms for the interceptor’s final stage. Lynred contributed the terminal infrared sensor, while Thales provided performance data for both naval and ground sensor options. GKN Fokker was involved in adapting the ammunition for the MK41 naval launcher.
MBDA has stated that this milestone showcases the consortium’s expertise in addressing hypersonic and ballistic threats, supported by comprehensive knowledge of air defense systems. The EDF has supplied €80 million in funding for the three-year Hydis initiative, complemented by an additional €60 million from the partner nations.
Meanwhile, the competing Hydef program has successfully acquired €100 million from the EDF and a further €10 million from participants including Belgium, Germany, Norway, Poland, and Spain. Diehl Defence is the major funding recipient for Hydef, receiving €34.7 million. Initially, Hydef triumphed in the EDF competition for hypersonic interceptor development in 2022, whereas the Hydis program was initiated following concerns raised by France and MBDA, who had previously invested in hypersonic technologies.
MBDA introduced its hypersonic interceptor concept, Aquila, at the Paris Air Show in 2023. Both Hydis and Hydef are part of the larger European Twister project, which aims to detect, track, and counter hypersonic threats using space-based early detection systems and endo-atmospheric interceptors.
