Germany and France have officially ended the fighter jet component of their Future Combat Air System (FCAS), a multinational defense project launched in 2017 to develop a next-generation warplane to replace the Rafale and Eurofighter by 2040. The collapse follows years of disputes between France’s Dassault Aviation and Germany’s Airbus Defence and Space over which company would lead the project. Dassault proposed a French-led model with Airbus as a subcontractor, a move Berlin rejected as undermining the joint nature of the program. Additional disagreements over the jet’s weight—France favoring a lighter carrier-capable model, Germany a heavier air-superiority version—further deepened the rift.

German Chancellor Friedrich Merz informed French President Emmanuel Macron that the project could not move forward, a decision Berlin communicated to Airbus in early June 2026. While the fighter jet element is now defunct, both governments agree to continue collaboration on drones and the 'combat cloud'—a digital network linking sensors, satellites, and aircraft. The French presidency suggested Germany unilaterally ended talks, maintaining that Franco-German cooperation remains essential for European defense.

The FCAS breakdown reflects broader challenges in European defense integration, as similar joint programs in maritime patrol aircraft, tanks, and artillery have also faltered. Despite the setback, German officials emphasize that the 'nervous system' of FCAS—the integrated digital backbone—will continue as a European 'system of systems.' The decision was announced ahead of the ILA air show in Berlin, where Chancellor Merz formally confirmed the shift in strategy.
