Grants for Space and Aerospace Companies in Belgium

Belgium is one of the largest per-capita contributors to the European Space Agency and hosts a thriving aerospace ecosystem. Companies like Spacebel, Thales Alenia Space Belgium, and Sonaca have built world-class capabilities in satellite systems, launcher structures, and Earth observation. This concentration of expertise means Belgian space companies have access to funding channels that most other sectors cannot tap into.

The Belgian space sector benefits from a unique combination of regional innovation grants, federal space budgets, ESA procurement contracts, and EU research programs. For a startup or SME working on space-related technology — whether satellite components, ground systems, space data analytics, or launch support services — the grant landscape is rich but fragmented across multiple layers.

Understanding which funding source fits your company stage and technology readiness level is the first step. A pre-revenue deep-tech startup will look at different programs than an established manufacturer seeking to industrialise a new product line.

ESA Business Incubation Centres support startups that use space technology or space data for commercial applications. ESA BIC Belgium operates through regional partners and offers up to €50,000 in funding, office space, technical support, and access to ESA expertise. The incubation period typically lasts two years.

To qualify, your company should be less than five years old and have a business concept that leverages space technology — broadly defined. This includes Earth observation data, satellite navigation, space materials, or any downstream application of space-derived technology. ESA BIC is not limited to companies building rockets; it actively supports companies using space data for agriculture, logistics, insurance, environmental monitoring, and more.

The application process involves a pitch to the ESA BIC selection committee. Having a clear technology-to-market pathway and a credible team are the most important selection criteria. Belgian ESA BIC alumni have raised significant follow-on funding, making the incubator a strong launchpad.

VLAIO (Vlaams Agentschap Innoveren en Ondernemen) supports aerospace companies through its standard innovation grant programs — R&D projects, feasibility studies, and the KMO Groeisubsidie for strategic growth trajectories. There is no aerospace-specific VLAIO program, but space and aerospace projects score well when they demonstrate technological novelty and economic impact in Flanders.

For R&D-intensive aerospace projects, the VLAIO O&O subsidie can cover 25-50% of eligible project costs, depending on company size and project type. Feasibility studies for new aerospace concepts can receive up to 50% support. VLAIO also supports collaborative projects between companies and knowledge institutions, which is common in aerospace given the sector's reliance on advanced research.

Flemish aerospace companies should also explore the VLAIO internationalisation support and cluster programs. Flanders has active aerospace cluster organisations that facilitate access to European supply chains and collaborative R&D opportunities.

Wallonia hosts the densest concentration of space companies in Belgium, anchored by Spacebel (satellite ground systems and on-board software), Thales Alenia Space Belgium (satellite payloads and instruments), and a network of specialised SMEs. The Walloon region supports aerospace innovation through SPW (Service Public de Wallonie) grants and Skywin, the Walloon aerospace cluster.

Skywin facilitates collaborative R&D projects within the Walloon aerospace sector, connecting large primes with innovative SMEs and research centres. Walloon companies can access SPW research grants, innovation grants, and investment support for industrial equipment. The co-financing rates are competitive, and aerospace projects benefit from the region's strategic focus on high-tech manufacturing.

Wallonie Entreprendre and Sowalfin also provide financing instruments (loans, equity) that complement grant funding for aerospace companies needing capital-intensive manufacturing investments.

Belgium's federal government allocates a dedicated budget to ESA programs, which directly benefits Belgian companies through ESA procurement contracts. The Belgian Science Policy Office (BELSPO) manages federal space research programs and can fund fundamental and applied research in space sciences.

At the European level, Horizon Europe includes dedicated space work programmes covering Earth observation, secure connectivity, space traffic management, and access to space. Belgian companies and research institutions have a strong track record in Horizon Europe space calls, often participating in consortia with partners across Europe.

The EIC Accelerator is another EU instrument relevant for space startups with breakthrough innovations. It provides grant and equity funding up to €17.5 million for deep-tech companies with high growth potential. Belgian space startups have successfully secured EIC funding in recent years.

Space and aerospace grants in Belgium are available to companies of all sizes — from pre-revenue startups to established industrial primes. The key qualifications vary by program: ESA BIC targets early-stage companies, VLAIO and SPW support SMEs and larger companies with innovation projects, and Horizon Europe is open to any legal entity in an EU member state.

The fastest way to identify which grants match your company is to filter by region, company maturity, and technology readiness level. A startup developing a new satellite component will pursue different programs than an SME offering space data analytics services.

Start by checking your eligibility through the BelGrant assistant, which can help you identify the strongest-fit grants for your specific space or aerospace activity. You can also explore the full innovation grants catalogue to see what's available across all Belgian regions.
