How to get funding for an aerospace startup in Europe

An aerospace startup in Europe gets funded by matching each funding route to its stage: ESA business incubation and NATO DIANA for early technology, the EIC Accelerator for innovations at TRL 6 to 8, European Defence Fund SME calls and the EU Defence Innovation Scheme for defence research and development, and the NATO Innovation Fund and defence-focused venture funds for equity. Most successful founders stack several of them, using non-dilutive grants to de-risk the technology and private equity to scale. This guide maps the main routes, what each one pays and who it is for.

Which funding routes exist for aerospace startups?

The landscape splits into four families: EU innovation grants, EU defence programmes, NATO instruments and space agency programmes, with private capital on top.

How does the EIC Accelerator work?

The EIC Accelerator is the EU's main instrument for single companies with breakthrough technology. It funds innovations that could create or disrupt markets at TRL 6 to 8, with a lump sum grant below €2.5 million over 24 months and an equity investment of €1 million to €10 million. Startups, SMEs, spin-outs and small mid-caps of up to 499 employees can apply, as can people planning to set up a company.

The process has stages. A short proposal with a pitch deck and video can be submitted at any time and is batched every first Tuesday of the month. Successful applicants write a full proposal for one of the 2026 cut-offs (7 January, 4 March, 6 May, 8 July, 2 September and 4 November), are interviewed by a technology expert, and the top proposals face a jury interview. Selection is competitive, so a clear market case matters as much as the technology.

What can defence-related startups get from the EU?

Two linked instruments matter most.

The European Defence Fund funds collaborative defence research and development. Its 2026 work programme earmarks €1 billion, including around €60 million for disruptive technologies and €60 million for non-thematic calls for SMEs. EDF grants require a consortium, normally three entities from three eligible countries; see how to find partners for an EDF consortium. Since 2026, every EDF project can also pass funds to smaller entities through cascade funding, which lets a startup join a funded project without a consortium seat.

The EU Defence Innovation Scheme (EUDIS) is the EDF's door for newcomers. It targets SMEs, start-ups and other non-traditional players and offers:

• defence hackathons held across Europe every spring and autumn;
• technological challenges where teams test their solutions against each other;
• business coaching of up to 15 days for SMEs in EDF research and development projects;
• SME and disruptive technology calls with lump sum grants;
• access to equity through the European Investment Fund's Defence Equity Facility.

The 2026 EDF work programme makes €231 million available for EUDIS.

EUDIS in numbers

The EUDIS site publishes figures that show how much of the defence budget now reaches newcomers:

The instruments are practical entry points. The spring 2026 defence hackathon, "Defending Airspace", ran from 26 to 28 March 2026 in eight EU locations. The 2026 technological challenge covers AI-based tactical situational awareness using swarms of small robots and drones. Matchmaking services appear at seven technology events across Europe in 2026, and Ukrainian entities are eligible for EDF cascade funding grants in 2026.

What do NATO's innovation instruments offer?

DIANA, NATO's Defence Innovation Accelerator for the North Atlantic, runs challenge programmes around defence and security problems. Selected innovators receive non-dilutive grants, access to 16 accelerator sites and more than 200 test centres across the Alliance, mentors, investors and routes to market with Allied militaries. It focuses on dual-use technology, so commercial startups with a defence application are its core audience.

The NATO Innovation Fund is a venture capital fund investing in deep-tech and dual-use companies through the lens of defence, security and resilience. It closed its first €1 billion fund in August 2023 with 23 Allies as limited partners, Belgium among them, and NATO describes it as the world's first multi-sovereign venture capital fund. It invests directly in start-ups located in participating Allied nations, which includes Belgian companies, and indirectly through deep-tech funds. Founders approach it as they would any venture investor: with traction, a team and a credible path to scale.

How DIANA has grown

DIANA was agreed at NATO's Brussels Summit in June 2021, has its headquarters at the Imperial College London Innovation Hub, a regional hub in Tallinn and a North American regional office in Halifax. It ran three pilot challenges in 2023, five in 2024 and ten in 2025, and kicked off its 2026 programme on 3 February 2026. Its areas of interest include artificial intelligence, autonomy, quantum technologies, biotechnologies and human enhancement, hypersonic systems, space, novel materials and manufacturing, energy and propulsion, and next-generation communications networks. Accelerator sites and test centres join through national ministries of defence, so the network keeps growing.

Is there Belgian money for defence research?

Yes, at federal level. The Royal Higher Institute for Defence, which supports the federal Defence, Industry and Research Strategy, runs calls for research and demonstration projects. Its science and technology pages list DEFRA, the Defence-related Research Action, with a 2026 thematic call on pulsed directed energy effectors, a call for demonstrator projects in maritime security, and SCRiMM 2026 for collaborative research in military medicine. A national project builds the defence reference and the relationship with Belgian Defence that later strengthens an EDF consortium. Regional innovation agencies also fund research and development; check their current programmes for dual-use eligibility.

Which private investors focus on defence and dual use?

Private capital for European defence technology has grown fast. Three examples show the range:

• The NATO Innovation Fund, a multi-sovereign venture fund of about €1 billion, described above.
• The Defence Equity Facility, run by the European Investment Fund, which supports private funds investing in defence and dual-use technologies.
• Corporate-backed funds. In July 2026 Airbus Defence and Space became anchor investor in E2D, a growth fund launched by AVP and Earlybird with a target size of €500 million, aiming at about 20 companies with an average investment of €25 million.

Defence investors ask questions that generalist funds do not: who owns and controls the company, whether its technology is export-controlled, whether it can work with classified information and which programmes or primes already know it. Prepare those answers alongside the usual metrics.

What about space-specific support?

The European Space Agency runs Business Incubation Centres across its Member States for startups that use space technology or space data. In Belgium, ESA BIC Flanders opened in Geel in December 2012 with Flemish research institutes VITO, SCK CEN and imec as technical partners, and ESA BIC Redu serves Wallonia. Check the centres directly for current intake rounds and support levels.

Which route fits your stage?

What does a funding stack look like?

An illustrative path for a Flemish counter-drone sensor start-up shows how the routes combine over three to four years:

Each step makes the next one easier: evaluators and investors look for evidence that others have already tested and backed the technology.

Which deadlines are coming up?

Several routes run on fixed dates. As published at the time of writing:

• EIC Accelerator full proposals: the last 2026 cut-off is 4 November 2026; short proposals can be sent at any time and are batched every first Tuesday of the month, so a short proposal has to be approved first.
• EDF cascade funding: the BattleVerse project's call for up to 20 SMEs and start-ups, on defence mission planning, simulation, training and operations, is open on the Funding & Tenders Portal until 16 November 2026.
• EDF 2027 calls: the next work programme sets the topics; following draft topics now gives a consortium time to form before the calls open.

Dates change, so confirm each one on the programme's own page before planning around it.

How do you improve your chances?

• Prove the defence or space need. Evaluators and investors look for a named user problem, not only a technology.
• Get the eligibility right early. EU defence money requires establishment and executive management in eligible countries and no control from non-associated third countries.
• Build a consortium before the call. Partner search for EDF calls takes months.
• Be qualified as a supplier. Primes buy from qualified suppliers; see how to get AS9100 certified as a small startup.
• Combine routes. A DIANA grant or EUDIS challenge result strengthens an EIC application, and both strengthen an equity round.

FADEC's Investment Council connects members to corporate venture capital, deep-tech funds, family offices, the EIB and EIF and national strategic funds, with an investor-readiness review returned within 21 days; the membership page explains which tiers include pitch slots.

How do you become investor-ready?

• Show programme traction, not only technology: a funded EDF or DIANA project, a prime evaluation, a pilot with an end user.
• Clean up the cap table and ownership chain, because control by non-EU entities can exclude you from EU defence funding.
• Classify your products for export control and know which licences sales would need.
• Build a data room with contracts, IP filings, test results and quality certificates.
• Know your grant pipeline, so investors see how non-dilutive money reduces their risk.

FADEC's Investor Readiness Sprint, an optional membership module, covers a six-week diagnostic, data-room build, pitch and investor shortlist, and the cluster says its Investment Council gives access to more than 40 mapped European aerospace and defence investors and funds.

Quick answers

What is the largest EU grant for an aerospace startup? The EIC Accelerator offers a lump sum grant below 2.5 million euro for innovation activities at TRL 6 to 8, which can be combined with an equity investment of 1 to 10 million euro from the EIC.

Can a civil startup get defence funding in Europe? Yes, if its technology has a defence use. The EU Defence Innovation Scheme targets SMEs, start-ups and other non-traditional players, and NATO DIANA supports dual-use technology with non-dilutive grants.

Is Belgium part of the NATO Innovation Fund? Yes. Belgium was one of the Allies that launched the NATO Innovation Fund, a multi-sovereign venture capital fund of about one billion euro.

Do I need a consortium for EU defence funding? For European Defence Fund grants, yes: normally three entities from three eligible countries. Other routes such as the EIC Accelerator, DIANA challenges and cascade funding from EDF projects accept single companies.
