Europe has the defense budget. The test now is delivery.

At this month’s NATO summit in Ankara, allies announced billions of dollars in new arms deals and reaffirmed their commitment to spend more on defense. European governments have made the pledge, and the money is real: European defense spending has doubled since 2019, and by 2030, European NATO member countries are projected to spend in excess of €800 billion a year, up €300 billion from 2025, with equipment spending alone nearly doubling. But committing money is the easy part. The harder question is whether Europe’s defense industry can turn it into equipment fast enough to matter. Europe’s largest defense manufacturers’ order books now average more than five years for production, and some are closer to nine. Money is flowing in faster than industry can turn it into equipment. But a purchase order is not equipment that can be deployed on the ground and the air. European countries have long duplicated capabilities rather than pooling them. The bottleneck sits in the defense industrial system. Deterrence relies on the chain from funding to contracts, then through production, deployment into services, then rapid innovation in the field. Europe’s next goal comes after the spending promise. The continent fields six times as many weapons platforms as the United States, because countries have long duplicated capabilities rather than pooling them. Production ends up split across many small runs that never reach an efficient scale. Ukraine, under pressure, has shown how fast a defense system can move, adapting tactics in weeks and building drone detection networks from consumer electronics. Europe needs to catch up and then accelerate. Four moves would help Europe accelerate. The first is multi-speed procurement. Software-led systems such as drones and targeting improve in rapid cycles throughout their deployment and need procurement that can keep up. Israel’s Iron Dome started out as far less capable than it is today and improved continuously in service. European defense ministries have already set up high-speed procurement units with dedicated teams and greater risk tolerance. These need to become mainstream, rather than the exception. Collaboration in procurement, maintenance and training brings costs down and delivery forward. The second is military collaboration to reduce fragmentation. Collaboration in procurement, maintenance and training brings costs down and delivery forward. The Tempest project, where the U.K., Italy and Japan are jointly building a next-generation fighter, demonstrates the model: shared development costs that no single country could carry alone. Recent bilateral maritime agreements, and Romania’s use of EU funding to buy European while expanding production at home, show the same logic spreading. The third is industrial consolidation, which is already underway and needs to move faster. Companies are driving it themselves. Airbus, Leonardo and Thales have agreed to merge their space divisions into a single joint venture with roughly €6.5 billion in revenue and 25,000 employees, and European defense mergers and acquisitions rose 35 percent year over year in the first half of 2025. McKinsey analysis finds that consolidation across key supply chain segments could unlock around €9 billion in annual synergies, more than the current equipment budgets of 24 of Europe’s 30 NATO members. The deepest opportunity sits below the big primes, among the thousands of tier two, three and four suppliers that still duplicate one another’s work. Europe can speed this up by harmonizing requirements, reducing national carve-outs and letting industry do the combining. Consolidation is only half the task. Europe also needs to build sheer capacity — more shipyards, more assembly lines, more of the physical plants that turn orders into hardware — and the capital to fund it. In several categories, Europe simply lacks enough places to build. Real deterrence means difficult choices, and a public that understands the importance and the cos
