Europe's Defense Renaissance: Building Sovereign Weapons for a New Era

The Lead: Europe's Defense Awakening

In a small workshop in England's East Midlands, engineers at the British startup Skycutter are designing weapons for Ukraine. The swarms of cheap, deadly and often autonomous drones deployed in that war have already changed combat completely, forcing European militaries to scramble to catch up in a drive to spend billions on weaponry. This push comes with added pressure from Donald Trump's wavering on the Nato alliance and the US president's insistence that members increase defence budgets.

The New Arms Race: Survivable vs. Attritable Weapons

Militaries do not believe they can totally dispense with people or heavier machinery such as tanks, artillery and ships. But a big chunk of the planned spending will go on drones of various sizes, whether for the air, land, sea or below the waves. Gen Sir Roly Walker, the UK's chief of the general staff, last year said he wanted the forces' equipment to be 20% "survivable" (because they have people inside), 40% "attritable" (you aren't too worried if they're destroyed), and 40% "consumable" (single use).

The growing feeling across Europe is that "we should be able to stand up on our own two feet," according to one person at a fast-growing weapons startup. "Sovereignty is about control. If you buy things off the shelf from elsewhere you are always ceding some control." That applies to parts and materials as well. The UK is consulting on how much needs to come from Britain for a product to be sovereign. Manufacturers cannot necessarily rely on parts and materials from various countries who could become adversaries – notably China.

The Financial Surge: €800 Billion and Counting

The EU has responded by promising to spend €800bn on defence over four years. The UK has also pledged to put aside more, with Keir Starmer likely to come under pressure to show progress after Labour's heavy losses in recent elections. A crop of well-funded startups are gaining momentum and expanding production, making big promises – many still unproven – that they can do a better job than traditional manufacturers and Silicon Valley rivals.

European defence tech unicorns include Helsing, a German company backed by the Spotify founder Daniel Ek, and the German drone makers Quantum Systems and Stark Defence. Stark and Helsing recently won orders from Germany's military for attack drones, while all but Quantum are investing in UK factories. The British missile maker Cambridge Aerospace – controversially chaired by the former defence secretary Grant Shapps – is reportedly also close to joining the billion-dollar ranks.

Geopolitical Shifts: Redefining European Defence Posture

The unsettling combination of Trump and war on the doorstep has sharpened long-running criticism that the continent has relied too much on US weapons makers. "A lot of supply chain diversification dreams have evaporated," says Kusti Salm, a former Estonian defence mandarin turned chief executive of the anti-drone missile startup Frankenburg. "I think it's natural if Europe wants to sustain its prosperity and freedom."

Ricardo Mendes, chief executive of the drone maker Tekever, says the advent of unmanned aerial vehicles has prompted "a radical transformation in how defence technology is built", with companies betting on future demand for kit rather than locking in long-term contracts before starting. Tekever, which Mendes co-founded in Portugal in 2001, reached a billion-dollar "unicorn" valuation last year, and has 1,200 people, including new factories in the UK's drone cluster in Swindon, Wiltshire, and another in Cahors, south-west France.

The Future Outlook: European Defence Innovation Ecosystem

US rival unicorns include the drone maker Shield AI, the autonomous boat company Saronic Technologies, and the anti-drone weapons company Epirus. But two companies with names taken from JRR Tolkien's Lord of the Rings lead the American pack: the software company Palantir and the autonomous weapons maker Anduril. Both are making significant inroads into Europe, particularly the UK, but that expansion is coming under scrutiny as European politicians balk at their stridently pro-Trump backers.

Palantir was backed by the billionaire Trump donor Peter Thiel. Thiel, a vocal critic of liberal democracies, has also backed Stark, which has raised concerns in Germany, though Stark says Thiel has no direct operational or strategic influence. Palantir's chief executive, Alex Karp, has repeatedly extolled American dominance, while Anduril is run by 33-year-old Palmer Luckey, who has personally hosted a Trump fundraiser and has cultivated close ties with the administration.

As Europe pours billions into defense technology and sovereignty, the landscape of global defense manufacturing is being reshaped. The coming years will determine whether European startups can deliver on their promises and establish a sustainable defense ecosystem independent of traditional suppliers and geopolitical dependencies.
