German defense strategists have presented a concept paper titled “Sparta 2.0,” outlining a plan for Germany and Europe to develop military capabilities independent of the United States.
As the authors themselves note, it is currently inconceivable for any “European war mission” to be conducted without US-provided “software or systems” and the corresponding approval from Washington.
The paper argues, however, that European countries could free themselves from this dependence within a few years, provided there is sufficient political will and financing amounting to €500 billion over the first decade.
The authors conclude that such spending is financially feasible. The document identifies 10 specific “capability gaps,” including some areas already under development by German companies, such as the mass production of unmanned aerial vehicles and the deployment of satellite constellations.
The authors state that the path toward European “defense autonomy” lies in “mobilizing Germany’s financial and industrial resources.”
Europe advised to pursue a “change of course”
According to German Foreign Policy, the new “Sparta 2.0” report, addressed to “German and European decision-makers,” first identifies severe deficiencies in the current state of military development in Germany and Europe.
The report states that although European countries now invest an amount equivalent to 60% of the US military budget in their armed forces, they remain “militarily dependent on the US at every level.”
This dependence extends not only to individual weapons systems but also to the entire operational chain, from satellite-based reconnaissance to fire control and battlefield operations.
The text offers a blunt assessment: “Without US approval, software or systems, no European war mission is currently conceivable.”
According to the strategy paper, unless there is a genuine “change of course,” the gap between Europe’s financial contributions and its military capabilities will continue to widen in the coming years.
Yet such a “change of course” is entirely achievable, the report argues. Europe, which possesses the world’s second-largest defense budget along with a competitive industrial and technological base, already has all the necessary preconditions.
Europe’s military shortcomings laid bare
“Sparta 2.0” identifies 10 strategic capability gaps in which Europe’s dependencies are considered critical. According to the document, closing these gaps through the development of German or European capabilities is “a strategic necessity.”
In some cases, particularly in the German defense sector, relevant efforts are already underway.
This applies, for example, to scalable autonomous systems, the serial production of all types of drones, and air defense systems.
German companies are also working on establishing a European satellite constellation and producing small and medium-sized launch vehicles capable of putting satellites into orbit.
The development and production of long-range precision weapons has meanwhile been initiated through multinational cooperation.
Other elements, however, including the establishment of a resilient command-and-control system and the development of a sovereign European data and artificial intelligence infrastructure, remain lacking.
In addition to the 10 “capability gaps,” the authors point to other “bottlenecks,” such as ammunition shortages and problems in medical logistics.
These issues, the paper states, will need to be resolved within the existing framework of Europe’s armed forces and defense industry.
Germany as the core of European military power
“Sparta 2.0” provides concrete details regarding both timelines and costs.
For example, “significant progress toward independent European operational capability” is described as a realistic objective within three to five years. “Comprehensive autonomy,” meanwhile, could be achieved “in most areas” within five to 10 years.
The authors estimate the cost at €150 billion to €200 billion by 2030, while approximately €500 billion would be required over the decade needed to achieve comprehensive autonomy.
This amounts to roughly €50 billion annually. For EU member states together with the United Kingdom and Norway, this would represent slightly more than 0.25% of economic output, making it financially achievable, the report says.
The approach could be pursued within the framework of a “Coalition of the Willing,” involving, in practice, Central and Eastern European states, the Nordic countries, and “traditional partners” in Western Europe together with the United Kingdom.
The paper explicitly acknowledges that Germany has increased its military budget far more than other European countries.
As a result, “the path to European defense autonomy” also “inevitably involves mobilizing Germany’s financial and industrial resources.”
Germany is thus positioned as the core of a future European military power.
The authors’ ties to the arms industry
Four of the five authors behind the “Sparta 2.0” concept had already published an article in March 2025 calling for an independent German-European rearmament effort aimed at reducing reliance on the US.
The authors exemplify the increasingly close overlap between state institutions, leading think tanks, and the arms industry.
Reserve officer Thomas Enders, for example, became president of the German Council on Foreign Relations (DGAP) in 2019 after spending many years at the helm of aerospace and defense giant Airbus.
Former Deutsche Telekom CEO René Obermann currently serves as chairman of Airbus and is set to become chairman of the supervisory board of software company SAP next year. SAP has operated a Defense Innovation Center in Munich since February.
Jeanette zu Fürstenberg, a startup investor, serves as European head of Silicon Valley venture capital firm General Catalyst.
Moritz Schularick is president of the Kiel Institute for the World Economy (IfW).
The newest addition to the group of authors is Nico Lange, senior fellow at the Munich Security Conference.
Lange, Obermann and Schularick, together with retired Lieutenant General Jürgen-Joachim von Sandrart, also form an advisory group established specifically within the Federal Ministry for Economic Affairs to support the growth of the security and defense industry.
Two of the five authors also maintain direct ties to Germany’s emerging drone industry. Fürstenberg was among the first investors in drone company Helsing, founded in 2021, while Enders has served on the company’s supervisory board since 2022.
One of Helsing’s three founders, Gundbert Scherf, was temporarily assigned to the Federal Ministry of Defense in 2014 while working as a consultant for McKinsey. Until 2016, he served under then-Minister Ursula von der Leyen as head of Strategic Armaments Management.
A Bundestag inquiry committee later examined the McKinsey networks that had been highly active during that period.
Helsing recently secured a contract together with Stark Defence to produce drones for the Bundeswehr, initially valued at €270 million and potentially expandable to €1.5 billion.
Among its other activities, Helsing is also involved in the development of the first combat drone manufactured in Germany.
The startup is preparing to launch a new funding round expected to raise €1.2 billion, more than any previous German startup financing round.
This would value Helsing at €18 billion, making it the most valuable startup in German history.
Helsing’s rival, Stark Defence, is also well connected in Berlin. The company’s senior vice president is retired Major Johannes Arlt, who served in the Bundestag for the SPD from 2021 to 2025 after holding various positions in the Bundeswehr and the Federal Ministry of Defense.
Marie Theres Niedermaier, previously a personal adviser on economic and financial policy at the Chancellery, also now works at Stark Defence.
Stark Defence likewise received an initial €270 million contract from the Bundeswehr for drone production.
The company also manufactures unmanned naval vessels and markets a command-and-weapons deployment system for all types of drones.
