German think tank flags €50B autonomy gap

European defense autonomy sounds abstract, but the object here is very concrete: missiles, drones, satellites, command networks, and the factories needed to keep them flowing in a war. A new paper called SPARTA 2.0 argues Europe is much closer to building that stack for itself than people assume. The authors say the gap is real, but not impossibly large — roughly €50 billion a year for a decade on top of current plans. What changed this week is that a high-profile German group put a number, a timeline, and a shopping list on the table. ### Who put this out? SPARTA 2.0 comes from a small but heavyweight German circle: Thomas Enders, René Obermann, Moritz Schularick, Jeannette zu Fürstenberg, and Nico Lange. The paper sits under the SPARTA initiative and was published in May 2026, with the Kiel Institute for the World Economy and the German Council on Foreign Relations orbiting the effort. That matters because this is not a fringe manifesto — it is establishment Europe trying to speak in startup speed. (sparta-alliance.eu) ### What are they actually claiming? The core claim is simple: Europe does not need total military self-sufficiency tomorrow, but it can get to a much higher degree of independent action within a few years if it spends differently and coordinates better. SPARTA 2.0 puts the added cost at €150 billion to €200 billion by 2030 and about €500 billion over the next decade — which is where the “€50 billion a year” line comes from. The authors frame that as roughly 10% of total European defense spending, or about 0.25% of GDP. (sparta-alliance.eu) ### Where is the gap? The paper points to ten capability gaps. The public summary names command systems, air defense, satellite reconnaissance, and scaled autonomous systems, and outside coverage adds deep strike to the list. The through-line is dependence on the U.S. across the whole chain — from seeing the battlefield to deciding, communicating, and firing at range. Europe has weapons companies, obviously, but the missing piece is an integrated system that can operate at scale without leaning on Washington. (sparta-alliance.eu) ### Why are drones and autonomy so central? Because Ukraine changed the economics of modern war. Cheap autonomous or semi-autonomous systems can find targets, absorb attrition, and force the other side to burn expensive interceptors. That makes “scaled autonomous systems” more than a buzzword — it is a production problem. Europe does not just need better prototypes. It needs lots of affordable systems, plus the software, networking, and command layers that make them useful together. (sparta-alliance.eu) That emphasis is explicit in SPARTA 2.0’s public summary. ### Why say the bottleneck is politics? Because the authors are blunt that money and technology are not the decisive constraint. Their line is that political prioritization and industrial coordination are. Basically, Europe already talks like the threat environment changed. Budgets are rising. But procurement is still fragmented, national, and slow — the old model where every country protects its own champions and timelines. SPARTA’s argument is that autonomy will fail unless governments buy toward a shared architecture instead of a pile of separate national programs. (sparta-alliance.eu) ### How fast do they think this can move? Faster than traditional European defense planning usually admits. Enders says Ukraine shows this does not take decades, and the paper argues substantial progress is realistic in three to five years, with much deeper autonomy in five to 10. That is an aggressive timeline, but it tells you what the document is trying to do: force planners to think in wartime cycles, not peacetime procurement calendars. (sparta-alliance.eu) ### Why does this matter now? Because the old European assumption — that the U.S. will always provide the high-end backbone — looks shakier than it did even a year ago. SPARTA 2.0 is really a response to that strategic uncertainty. The paper is saying Europe does not need a fantasy superstate to close the gap. It needs a narrower thing — shared priorities, faster buying, and industrial scale in the capabilities that now decide wars. (defensenews.com) ### Bottom line This is less a warning that Europe is doomed than a challenge to stop pretending the problem is unknowably huge. The German group’s message is that the bill is large but manageable. The harder part is choosing to build the right things, together, on time. (sparta-alliance.eu)
