Strasbourg: The European Parliament has again adopted proposals to build what it calls a genuine single market for defence, aimed at closing the capability gaps that years of underinvestment left behind. The ambition is correct and the diagnosis is sound. The harder truth, which the votes themselves cannot change, is that a single defence market is one of the most difficult things the Union has ever set out to create, for reasons that are political before they are technical.
Start with the problem the proposals are meant to solve. European defence spending has risen sharply, but it is spent badly. The continent operates a bewildering number of different main battle tank types, fighter platforms and frigate designs, where the United States fields a handful. Fragmentation means short production runs, duplicated research, weak bargaining power against suppliers and armies that struggle to fight together because their equipment does not interoperate. Pooling demand across twenty-seven national markets would, in theory, deliver scale, lower unit costs and faster fielding. The logic is the same that built the single market in goods, applied to the one sector member states have always guarded most jealously.
That jealousy is the obstacle. Defence procurement is not merely commercial; it is industrial policy, employment policy and sovereignty rolled together. A French order sustains French jobs and French strategic autonomy, and a decision to buy a German or shared European system instead is felt as a domestic loss even when it is a collective gain. The Treaty itself preserves national prerogatives in security, allowing governments to invoke essential security interests to keep contracts at home. Every incentive at the national level pulls against the consolidation the Union needs at the continental level. This is the classic collective action problem, and it does not dissolve because a chamber in Strasbourg votes that it should.
The emergence in May of a cross-party European Defence Union Group, drawing roughly thirty members from eleven states, signals that political will is hardening. So does the broader Readiness 2030 effort and the industrial financing instruments now taking shape. These are meaningful shifts, and a war on the Union’s eastern edge has done more to concentrate minds than a decade of strategy papers. But will at the parliamentary level is not the same as authority over national budgets, and that is where the real decisions are made. Parliament can frame, fund at the margins and exhort; it cannot order a member state to abandon a national champion.
There is also a sequencing risk worth naming. Building an integrated market takes years of harmonised standards, joint procurement vehicles and trust between national arms industries. The capability gaps are urgent now. The danger is that governments, facing immediate pressure to rearm, place fast national orders that lock in the very fragmentation the single market is meant to undo. Speed and consolidation pull in opposite directions, and under threat, speed usually wins. Money spent quickly today can entrench the duplication that the long-term project exists to remove.
The constructive reading is that direction matters even when pace disappoints. Each joint procurement, each shared standard, each common financing line builds a precedent and a constituency with an interest in deeper integration. The single market in goods was not built in one treaty but accreted over decades through exactly this kind of incremental, contested progress. Defence may follow the same path, slower than its advocates wish and faster than its sceptics expect.
For now, the honest verdict is that Europe has the analysis right and the architecture missing. The proposals adopted this week are a statement of intent backed by real but limited tools. Whether they become the foundation of a true defence market or another well-argued document depends on something Parliament cannot legislate, the willingness of national capitals to spend collectively what they have always insisted on spending alone.
