Is Europe Really Becoming a Defence-Tech Powerhouse?

European defence tech used to occupy an awkward corner of the startup world. Many investors avoided it, founders often looked elsewhere, and defence itself was largely associated with established contractors building enormously complex systems over very long periods of time.

That has changed quickly.

In 2025, European startups working across defence, security and resilience raised a record $8.7 billion in venture capital, almost four times the amount raised in 2020. The biggest shift came at the later stages, where funding more than tripled to $4.7 billion. Early-stage investment, however, actually declined. That makes the current boom slightly more complicated than the headline suggests: Europe does not have a simple shortage of defence capital anymore. It has a problem getting the right capital to the right companies at the right stage.

Government spending has moved just as dramatically. Defence expenditure across the EU reached €343 billion in 2024 and was projected to rise to €381 billion in 2025. The EU's wider Readiness 2030 plans could create room for hundreds of billions more in defence spending over the coming years.

By European industrial-policy standards, this is a dramatic shift.

But spending more money on defence does not automatically make Europe a defence-tech powerhouse. Neither does producing an impressive collection of highly valued startups.

A powerhouse is able to turn technology into equipment that gets bought, built, deployed and improved, then do it again at scale.

There are now credible signs that Europe can do the first part.

German drone company Quantum Systems has grown from a startup into a serious defence supplier, raising $1.2 billion in 2026 at a valuation of around $8 billion. Spain has ordered 91 of its Vector reconnaissance systems, comprising 182 drones, while the company secured a €150 million European financing package to expand its production and technology development.

TEKEVER offers another example. Its unmanned aircraft have gained operational experience through their use in Ukraine, and the British government selected its AR5 system in 2026 for a programme worth up to £400 million, subject to final contracting and approvals.

Helsing has followed an even more dramatic trajectory. The European defence AI company raised $1.8 billion in 2026 at an $18 billion valuation while developing autonomous systems and supplying technology for use in Ukraine.

These are no longer simply startups promising that their technology might one day matter.

Europe is producing defence-tech companies with serious capital, real government customers and technology moving into operational use.

That part of the story holds up.

The complication is what happens when those companies try to move from an impressive technology to something governments can buy repeatedly and deploy across Europe.

Inside the EU, defence remains fragmented between countries with their own budgets, purchasing processes, technical requirements and political priorities. A company can develop technology relevant to several European militaries and still find itself navigating those markets largely one government at a time.

The European Commission has acknowledged the problem remarkably openly. Its own work describes defence procurement as lengthy, complex and fragmented along national lines. Many processes were designed around large established contractors and technologies developed over long periods, not smaller companies producing software, drones, AI and autonomous systems that can change substantially within a year.

That creates a strange contradiction.

Europe increasingly wants software-speed innovation from a procurement system built for a much slower defence industry.

For technologies such as drones, that matters enormously. A product can change significantly between the beginning of a traditional purchasing process and the point at which governments finally decide what to buy. Testing requirements, certifications and different national rules can add another layer of delay.

More money does not automatically solve any of that.

A defence startup does not become strategically important because investors value it at €5 billion. It becomes strategically important when governments buy what it builds, the company can manufacture enough of it, armed forces can actually use it, and the technology continues improving after deployment.

This is also why Europe's financing picture deserves a closer look. Smaller defence companies still report significant difficulty accessing capital, particularly before they have major government contracts. Recent European research describes two separate points where promising technologies can die: first while trying to move from development into procurement, and then again while trying to turn initial orders into large-scale production.

So one of Europe's biggest bottlenecks is increasingly the journey from invention to adoption, and from adoption to scale.

That makes startup valuations a surprisingly poor measure of whether Europe's defence-tech strategy is succeeding.

The better questions are less glamorous. How quickly can a new company get its technology in front of military users? How long does it take to secure the first serious order? Can a system bought by one European country be sold easily to another? Can manufacturers expand production quickly enough when demand suddenly rises?

Those are the questions that determine whether technological ambition becomes military capability.

And they lead to a much more practical definition of the technological sovereignty Europe has spent years discussing.

Sovereignty is not having the technology somewhere in Europe. It is being able to build enough of it when Europe actually needs it.

That is a considerably higher bar.
