The $500B Opportunity in Europe’s Defense Buildout

Summary

• Ukraine made production scale indispensable alongside technology. George Hadjiminas says decades of European underspending left weaknesses in the ability to manufacture and supply at scale. Aistis Šimaitis argues that “technology and volume” win together, but if forced to choose, “you’d rather have a million of something than one of anything.” Systems must now be manufacturable in tens of thousands, hundreds of thousands, or millions.
• The manufacturing layer, not another neo-prime, is framed as the clearest white space. Bruno Wejchert points to Europe’s fragmented supplier base and component lead times measured in years, which help explain why primes can take four or five years to deliver certain contracts. Onodrim’s strategy is to acquire strong manufacturing and critical mission-system businesses that can supply the next generation of primes.
• Autonomous warfare forces military component costs down as deployment volumes rise. Aistis’s example is a military radio that could acceptably cost $30,000 four years ago but cannot support fleets ranging from hundreds to tens of thousands of robots at that price. Cameras and other formerly “exquisite” components face the same cost-and-scale reset.
• The winning model combines technological leadership with industrial competence. George calls adoption an evolution rather than a revolution: “Prototypes don’t fight wars,” so advanced systems still require supply chains capable of delivery. Aistis proposes a complementary split between software, AI, integration and testing companies and specialized industrial producers.
• Europe’s weakness is less technological inferiority than institutional fragmentation. George sees capabilities broadly comparable with the US, but Europe has more protected national champions and fewer startup-to-scale-up successes such as Anduril or Palantir. Bruno adds that procurement remains divided by country and European-level processes, leaving Europe behind US-style government–OEM partnerships. Aistis says government remains the buyer; EU initiatives and what he describes as a trillion dollars being poured into defense by 2030 are attracting private funding.
• Government procurement can separate funded prototypes from durable defense businesses. Bruno says startups financed with only $5 million or $10 million may have superior products yet lack the hundreds of millions, workforce, and operating history governments associate with reliable delivery. Incumbents may have worked with governments for 10 or 20 years, employ thousands, and hold millions or hundreds of millions on their balance sheets. Meanwhile, companies such as Helsing and ICEYE have already become “de facto kingmakers” and could keep taking share from traditional primes.
• The upside case is a European defense company worth half a trillion dollars within a decade. Bruno conditions that outcome on Europe excelling at both local manufacturing and “building the intelligence layer for defense,” with the company possibly founded in the past five years. His timing remains explicitly hedged: “Don’t quote me on that, but I think it could be done in the next decade.”

Deep dive

1. Ukraine made scale indispensable alongside technology

• George’s starting point: decades of European underspending left weaknesses in Europe’s ability to manufacture and supply militaries at scale. Ukraine exposed those weaknesses, while the subsequent influx of defense spending created room for companies to industrialize and grow.
• Aistis’s sharper formulation is “technology and volume,” with volume winning the tie. Pre-invasion defense favored exquisite technologies that were “dreams of generals” but could not be mass-produced; today, relevance requires output in tens of thousands, hundreds of thousands, or millions. Ideally, those systems should also not be easily copy-pastable.
• Bruno adds a battlefield corrective: systems tested in the United States and deployed in Ukraine sometimes “didn’t work” initially. They improved through repeated update cycles, demonstrating that technical promise must survive real-world iteration before scaling.

2. Europe’s manufacturing gap is the investable bottleneck

• Onodrim is deliberately “not building like another prime or neo-prime.” Its model is to acquire strong European manufacturing and critical mission-system businesses, strengthen them, and enable defense primes to deliver over the next decade.
• Bruno sees the same opening beneath neo-primes such as Helsing: Europe’s manufacturing base is fragmented, key component lead times can run for years, and outdated supply chains help explain why certain primes take four or five years to deliver on certain contracts.
• Autonomy compounds the constraint by demanding lower unit economics. Aistis argues that a $30,000 military radio might once have been acceptable, but not when systems require hundreds or tens of thousands of robots; cameras and other components must likewise become “significantly cheaper” and available at far greater scale.

3. Technology and industry must evolve together

• George rejects the technology-versus-industry binary. Theon was mostly an industrial company four or five years ago, with night vision as its main product; it has since branched into new technologies. Its electro-optics focus spans man-portable and platform applications, including examples such as night vision, augmented reality, and head-up displays. The company also completed an IPO in 2024 and has maintained a strong growth trajectory.
• George describes adoption as gradual rather than revolutionary: new technologies are incorporated into existing platforms and systems. His constraint is categorical: “Prototypes don’t fight wars.” Competitiveness requires both leading technology and enough industrial acuity to deliver it repeatedly.
• Aistis favors two complementary company types: technology businesses focused on software, AI, the connected battlefield, weapon final assembly, and testing; and industrial specialists producing their components. The winning relationship is collaborative and “non-zero-sum,” not an attempt by every technology company to become a manufacturing giant.

4. Fragmentation, not capability, separates Europe from the US

• George considers European and US technological capabilities closer than commonly assumed. The larger gap is organizational: the US produced startup-to-scale-up successes such as Anduril and Palantir, while Europe’s competing national interests preserve more national champions than a fully competitive market might support.
• Bruno’s procurement pushback is that US and European processes are not comparable. European purchasing remains fragmented between national and European levels, parts of the existing military-industrial complex are outdated, and some countries hold large volumes of systems that are not necessarily working. Europe also trails US government partnerships with companies such as Anduril or Hadrian.
• Aistis says government remains the buyer; theories about private military corporations replacing that model have not yet materialized. He points to EU initiatives and a trillion dollars being poured into defense, saying that by 2030 this is triggering venture and private funding.
• Aistis nevertheless sees favorable talent inputs. He says his co-founder and CTO, Alex, returned to Germany with his family two weeks earlier after 17 years in the United States to strengthen European defense, reflecting the broader talent demand he sees.

5. Scale-ups, not just startup novelty, will sort winners

• Bruno expects harsh sorting among venture-backed companies. A company funded with $5 million or $10 million may build a superior product, yet governments may have little belief in its ability to deliver and manufacture at scale compared with a company that has worked with government for 10 or 20 years, employs thousands, and holds millions or hundreds of millions on its balance sheet.
• Some winners are already “de facto kingmakers”: Helsing in Germany and ICEYE at the European level for SAR applications could keep taking share from traditional primes. George’s corresponding hot take is “scale-ups over startups”—finding the right fit with the capacity to scale rather than another purported revolution.
• Aistis’s Palantir lesson is to focus on becoming important and valuable rather than optimizing for the next year’s revenue. He cites Palantir being unprofitable for, in his words, “over 15 years” and “now being fit,” concluding that “the money will come.”
• In the closing “secret” answers, Aistis says choice is an illusion and cites research suggesting people think after they feel. Bruno says he thinks the next five to 10 years of AI-driven scientific knowledge could be equivalent to 100 years of manual human research, fundamentally changing the world faster than many realize.
• Bruno’s bull case is a half-trillion-dollar European defense company within the next decade, contingent on Europe mastering both local manufacturing and the intelligence layer.
