Brussels: Europe has spent three years talking about defending itself together. Now it has a concrete list. On 3 July 2026 the Commission proposed the first five defence projects of common interest, covering drones and counter-drone systems, maritime and seabed defence, space, air and missile defence, and the security of the bloc’s eastern flank.

The label matters. By naming these as European Defence Projects of Common Interest, or EDPCIs, the Commission borrows a mechanism it already uses for energy and transport, where flagship cross-border projects win priority and pooled money. Applied to weapons, the idea is to stop 27 armies buying 27 slightly different systems and to build shared capabilities that work across borders instead.

Big ambition, modest first cheque

The numbers reveal the gap between aspiration and today’s budget. The Commission has earmarked 325 million euros from the 1.5 billion euro European Defence Industry Programme to launch the projects. Yet the combined funding ambition attached to them reaches around 190 billion euros by 2036, a figure that dwarfs the seed money on the table.

That mismatch is the central tension. The seed funding is real but small; the headline ambition depends on member states pouring in national budgets, joint borrowing and private investment over the next decade. History gives reason for caution, because grand European defence plans have often shrunk once national treasuries and industrial champions start protecting their own.

Who is in, and who decides

Participation is broad. On average 18 member states join each project, a sign that appetite for collective defence has widened well beyond the usual core. Ukraine takes part in four of the five, folding a country at war directly into Europe’s industrial planning, and Norway may join too.

The projects track the threats Europe has felt most sharply. Drones and counter-drone systems answer the cheap aerial weapons reshaping modern war. Maritime and seabed defence reflects anxiety over undersea cables and pipelines. Air and missile defence and the eastern flank measures point squarely at the pressure along the border with Russia.

Yet the proposal is not settled. The Council must still deliberate on formally establishing the EDPCIs, and member states will weigh how much control over defence procurement they are willing to pool. Defence has long been the field where European integration slows, because armies, budgets and industrial jobs stay national in a way that few other sectors are.

The choice of projects also raises the question of overlap with NATO, which plans much of Europe’s collective defence already. Brussels argues the EDPCIs fill an industrial gap rather than a military one, building the factories and supply chains that let Europe produce what it has promised to field. Whether allies read it that way will shape how the initiative lands in capitals that prize the transatlantic link.

For now, the significance lies in the shift from principle to project. Europe has moved from declaring that it must defend itself to naming five specific things it intends to build together. The money attached is modest and the politics unresolved, but the list exists. The next test is whether member states treat it as a shared commitment or a menu they can quietly walk away from.
