Paris, September 3 - Europe’s ambitious Future Combat Air System (FCAS), a collaborative project between France, Germany, and Spain to develop a sixth-generation fighter jet and associated systems, is facing significant challenges due to ongoing disputes over ownership and leadership, particularly between France and Germany. Launched in 2017 by French President Emmanuel Macron and then-German Chancellor Angela Merkel, the FCAS aims to replace France’s Rafale and Germany and Spain’s Eurofighter jets by 2040, integrating advanced technologies like swarming drones and a "combat cloud" network. The project, estimated to cost over 100 billion euros, is led by Dassault Aviation for France, Airbus for Germany, and Indra for Spain, with additional partners like Safran and MTU Aero Engines working on critical components such as the engine. However, tensions over workshare distribution and intellectual property rights have repeatedly delayed progress, threatening the program’s timeline and Europe’s goal of achieving greater strategic autonomy in defense.

The core of the Franco-German dispute centers on France’s push for a dominant role in the project. Reports indicate that France, through Dassault Aviation, has demanded an 80% workshare in key pillars of the FCAS, including the Next Generation Fighter (NGF) airframe, engine development, and sensors, leaving Germany with leadership over less critical components like the combat cloud and remote carriers. This demand has sparked significant backlash in Germany, where stakeholders argue that such an arrangement would effectively turn the FCAS into a French-led project funded heavily by German resources. The German defense ministry has warned that conceding to these demands could undermine the capabilities of the future fighter and limit German industry’s participation. These tensions have stalled the transition to Phase 2, which involves building airworthy demonstrators, a critical step planned for completion by the end of 2025 to enable test flights around 2029.
High-level talks between French and German leaders, including a recent meeting between Macron and German Chancellor Friedrich Merz in Toulon in August 2025, have yet to resolve these issues. Merz has emphasized the need for a decision by year-end, acknowledging the project’s importance for European defense but expressing frustration with French demands for sole leadership. Germany has also faced internal pressures, with some voices suggesting alternatives such as joining the rival Tempest program led by the UK, Italy, and Japan, or increasing purchases of American F-35 jets. These options, however, could undermine the FCAS’s goal of fostering European sovereignty, as reliance on non-European systems would weaken the continent’s defense independence. The disputes also reflect differing strategic priorities: France requires a carrier-capable jet for its navy and nuclear deterrence capabilities, while Germany focuses on air superiority and long-range missions, complicating efforts to align requirements.
The FCAS’s future hinges on whether France and Germany can reconcile their industrial and political differences. Despite commitments from both nations to advance the program, the ongoing impasse threatens to delay or even derail Europe’s largest defense project. The upcoming German parliamentary elections in October 2025 could further complicate negotiations, potentially slowing funding approvals. Meanwhile, Spain, which joined the program in 2019, has remained relatively neutral but is equally invested in its success. If unresolved, the disputes risk not only the FCAS but also broader Franco-German defense cooperation, including the related Main Ground Combat System (MGCS) tank project. For Europe to achieve its vision of a technologically advanced, sovereign defense capability, compromise and clear governance will be essential to move the FCAS forward.
