The European Union has placed a wager on its own security unlike any in its post-Cold War history. The ReArm Europe Plan, formally rebranded as Readiness 2030, envisions mobilising up to €800 billion in additional defence spending by the end of the decade, anchored by a €150 billion loan instrument called Security Action for Europe, or SAFE, and a parallel fiscal carve-out that allows member states to spend up to 1.5 percent of GDP above standard deficit ceilings for four years. The numbers are extraordinary by Brussels’ historical standards, and the political signalling is unambiguous: Europe intends to defend itself, with or without the level of American backing it once took for granted. Yet for all the architectural elegance of the package, the harder question is whether the Union can convert money into capability fast enough to matter, and whether the political consensus underwriting the plan can survive contact with the actual mechanics of joint procurement, industrial workshare and parliamentary fatigue.
Begin with the arithmetic. EU defence expenditure reached €343 billion in 2024 and is forecast to climb to €381 billion in 2025, with the bloc collectively passing the 2 percent of GDP NATO threshold for the first time. Defence investment rose by 42 percent in 2024 alone, with €106 billion allocated and €88 billion of that flowing to equipment procurement. These are not modest figures. But the commitment Allies made at the June 2025 NATO summit, a 3.5 percent of GDP core defence spending target by 2035, implies an additional outlay of at least €288 billion every year for the next decade. The gap between aspiration and current trajectory remains very large, and it widens further once one weights the demand by capability category: air and missile defence, drones, deep-precision strike, electronic warfare, and the strategic enablers that European armed forces have historically rented from the United States.
The deeper problem, however, is not money. It is fragmentation. The European Defence Agency set a 35 percent collaborative procurement benchmark in 2007. Eighteen years later, collaborative procurement still hovers below 20 percent of total defence investment. Only 12 member states submitted complete data to the EDA’s most recent reporting cycle, an indicator of how thin the culture of pan-European cooperation actually is once one moves past the press conferences. Between 2005 and 2023, roughly 37 percent of EU defence equipment was imported from outside the Union, and around 80 percent of EU financial support to Ukraine was spent on non-European products. The 1.5 million artillery rounds delivered to Kyiv under the Czech-led initiative in 2024 were sourced entirely from third countries. A defence union that depends on third-country suppliers for the materiel of its first true war on the European continent in eighty years is not yet a defence union.
The Readiness 2030 Roadmap, presented in October 2025, attempts to confront this honestly. It sets a target of 40 percent joint procurement by end-2027, an ambition rather than a forecast, and 55 percent of investment flowing to the European defence technological and industrial base by 2030. It introduces four flagship initiatives: an Eastern Flank Watch, a European Drone Defence Initiative, a European Air Shield, and a European Space Shield. The Commission has paired this with a Defence Readiness Omnibus designed to fast-track permits, simplify joint procurement rules, and ease cross-border military transit toward an EU-wide military mobility area by 2027. SAFE has already attracted loan requests from 19 member states; the national escape clause of the Stability and Growth Pact has been activated for 17. On paper, the machine is humming.
In practice, three frictions deserve more candour than they have received. The first is industrial nationalism. The 2025 clash between Airbus and Dassault over the Future Combat Air System made plain how quickly cooperative programmes degenerate into workshare disputes once leadership, intellectual property and production location are on the table. Article 346 of the Treaty on the Functioning of the European Union, which lets member states bypass single-market rules on national-security grounds, has long served as a constitutional licence for these instincts, and no Commission omnibus can repeal it. As long as procurement is treated by capitals as an industrial-policy lever for domestic champions, the 40 percent joint procurement target will read more like a slogan than a forecast.
The second is the absorptive capacity of European industry. Production lines for 155-millimetre shells, air-defence interceptors and tactical drones cannot be expanded by directive. They require multi-year offtake contracts, skilled labour pipelines, raw-material guarantees and energy-cost predictability, the last of which intersects awkwardly with Europe’s climate commitments and the reluctance of large institutional investors, pension funds especially, to underwrite defence assets on ESG grounds. The European Investment Bank has tripled its intermediated lending to defence suppliers to €3 billion and elevated security to a horizontal public-policy goal, but the distance between that envelope and the annual delta implied by the new NATO target remains chasmic.
The third friction is democratic. SAFE was adopted under Article 122 of the Treaty, the emergency-instrument clause previously used to launch NextGenerationEU during the pandemic, which sidelines the European Parliament in the procedure. Speed is a real virtue when adversaries are setting the tempo, but procedurally thin legitimacy is a fragile foundation for a decade-long industrial transformation that will inevitably involve closed factories, displaced workforces and unpopular fiscal trade-offs in member states already squeezed by demographics, the green transition and rising social-spending pressures.
None of this is a counsel for paralysis. Russia’s grey-zone incursions across EU airspace, the calibrated sabotage campaigns documented across several capitals, and the visible drift in American strategic priorities have made the cost of inaction self-evident. The 17 member states that have activated the escape clause did not do so frivolously. But Europe should resist the temptation to grade the project by inputs alone, the billions pledged, the communiqués issued, the escape clauses activated, and insist instead on outputs: filled magazines, integrated air defence over the eastern flank, deployable formations capable of sustained operations, an Eastern Flank Watch that actually watches, and a single market for defence equipment that exists in fact rather than in roadmap.
There is, finally, the matter of Ukraine. The decision to associate Kyiv with the European Defence Fund, to extend SAFE eligibility to Ukrainian industry on the same terms as member states, and to integrate Ukrainian innovation, particularly in drones and electronic warfare, into the European technological base, may turn out to be the single most consequential element of Readiness 2030. Ukraine is the only European actor that has tested its defence-industrial base at war-time tempo since 1945. If the Commission’s instruments succeed in absorbing that learning rather than merely subsidising it, the Union will emerge with a credibility it has not previously possessed. If not, the gap between Europe at war and Europe legislating about war will widen further.
The seriousness of the moment is finally being met with the seriousness of the response. Whether the response is being met with the discipline it requires is the question the next two European Council cycles will answer, and the only honest verdict on Readiness 2030 will arrive long after the press releases have faded.
