European officials often decry the coincidence of Russian aggression and US unpredictable indifference. But this can be read the other way around: Ukraine’s pace of innovation and European scaling capacity—both of which would have lain dormant without the said coincidence—just might be the perfect mix. Hold on to your hats, the ride is wild.

For decades, European defence firms took their time. The gap was measurable. The average time between taking an order and delivering a product—what insiders call backlog-to-revenue—runs to 3.7 years in Europe, against 2.4 years in the United States. That sluggishness is now under assault from an unlikely direction: a war-torn country of 40m people that has, out of necessity, turned into a defence technology powerhouse.

Ukraine has developed and mass-produced interceptor drones while the United States has struggled to deploy far fewer at far greater cost. Drone deliveries in the first four months of 2026 already doubled the total for the whole of 2025, driven by parallel procurement channels including state contracts, the ‘Army of Drones’ bonus scheme, and the DOT-Chain marketplace .

A contagious ambition

New models such as the Terra A1 and the P1-SUN—the latter air-launched from modified An-28 transports to hunt incoming UAVs at a fraction of missile costs—illustrate the pace of iteration. On 2 February, Germany unveiled a new highly manoeuvrable hypersonic missile in a fraction of the time and cost it took American firms to debut theirs. The message to Europe’s legacy primes was blunt: speed up or step aside.

That ambition is proving contagious. A pan-European market for low-cost interceptor drones has emerged, with NATO buyers evaluating Ukrainian-designed kill-drones that cost between $1,000 and $3,000 per round and have already logged thousands of Shahed kills on the battlefield.

The British-Ukrainian startup Skycutter exemplifies the new model: 3D-printed airframes built in Britain, mass-assembled in Ukraine, priced at roughly £2,000 per unit, and put through more than 100 design iterations in three years to keep pace with Russian jamming tactics.

Europe is not merely spending more on defence—it is spending differently. From 2022 to 2025, European defence-tech spending rose thirteenfold while American spending on new technology only doubled, according to Jonathan Dimson, a senior partner at McKinsey. Mr Dimson added that investment in European defence-tech startups from 2021 to 2024 was more than five times greater than in the previous three-year period.

Spending where it counts

The European Defence Fund’s 2025 call injected €1.07bn into 57 projects explicitly framed around lessons from the Ukraine war. Drones, autonomy, and rapid iteration topped the list.

The hypersonic domain illustrates how Europe is now pursuing sovereign capability at both ends of the threat spectrum. France’s V-MAX glide vehicle has completed its demonstration flights; its successor, V-MAX2, aims for Mach 16 tests by 2027, paired with a new 2,500 km ballistic booster.

On the defensive side, the EU’s HYDIS and HYDIS² programme, led by MBDA and backed by 14 nations, completed its Mission-Definition Review in 2026 and down-selected to a single interceptor concept, drawing €80m in EU funding and €60m in national contributions, managed by OCCAR. Meanwhile, the German-British startup Hypersonica raised €23m in Series-A funding, built a prototype in nine months, and is targeting an operational European hypersonic missile by 2029.

Not everyone in the establishment has absorbed the lesson. Rheinmetall’s chief executive famously dismissed Ukrainian drones as ʼLegosʼ, a remark that ignited a sharp debate about the agility gap between nimble startups and century-old manufacturers. Think-tanks warn that unless European firms adopt Ukraine-style rapid feedback loops, they risk forfeiting the next wave of defence technology leadership.

The trust deficit

Driving Europe’s push for self-reliance is something harder to quantify than procurement timelines: a collapse in public trust towards the United States. A Pew poll found that 63 per cent of European respondents prefer European-made security technologies, even at higher cost, because they regard US President Donald Trump’s influence as a security risk.

A separate poll by Swiss technology company Proton found that nearly three-quarters of Europeans believe their countries are too dependent on American technology. One American financier who works with both European and US defence firms traced the shift to US Vice-President James Vance’s speech at the 2025 Munich Security Conference.

“The Europeans were aghast…They couldn’t believe it. They were very upset. Very quickly. They realised that, okay, you know, ‘We have to be resilient,’” the financier was quoted as saying. “I don’t think it’s widely appreciated how big of a deal it is.”

Open-source acceleration

Eric Brock, co-founder of the venture capital firm Ondas, which backs startups working closely with Ukrainian troops, sees the same dynamic shaping commercial decisions. European governments increasingly want to buy made-in-Europe products, he said. American companies could pursue joint ventures, but only if they abandon old habits.

I think it’s going to be hard for the established defence manufacturers who are so embedded with the Department of War to localise in Europe. — Eric Brock, founder of Ondas

“We…want to bring European capital as well to match ours. So it can’t be the bigger, American company coming in and dictating,” Mr Brock said. “I think it’s going to be hard for the established defence manufacturers who are so embedded with the Department of War to localise in Europe. Some of the emerging players on the fast cycle, like the companies we are working with, will have an easier time.”

The open-source question cuts across both the technology and the trust debates. Europe has noted how Ukraine’s use of open-source software has accelerated innovation, and the EU has made explicit efforts to encourage its adoption.

Ukraine sets the tone

Major primes such as MBDA and Airbus have already embedded Ukrainian engineers into fast-cycle research cells for counter-drone and loitering-munition projects funded under the SKYRAPTOR and TALON lots of the European Defence Fund.

Governments are rewriting procurement rules to match: Germany’s federal innovation agency co-funded Hypersonica, and Britain fast-tracks small-lot drone purchases through its G-TEAD pipeline, mirroring Ukrainian minimum-viable-weapon cycles.

Europe is yet to get anywhere near the end of the road leading to strategic autonomy. But for the first time in its short history, it has stepped on the gas.
