France and Germany have decided to abandon their flagship effort to jointly develop a next-generation combat aircraft, according to two German officials, bringing an end to one of Europe’s most significant defense initiatives.
The decision was reportedly reached during discussions between German Chancellor Friedrich Merz and French President Emmanuel Macron on the sidelines of the EU–Western Balkans summit in Montenegro last week. After months of stalled negotiations, both leaders concluded that there was little chance of resolving the impasse that had hampered the program.
The collapse of the €100 billion ($116 billion) initiative highlights the broader challenges Europe faces in strengthening its defense capabilities after years of limited military investment.
The program envisioned an advanced fighter aircraft operating alongside autonomous drones and connected through a highly secure digital network known as a “combat cloud.” However, disagreements over governance, technical requirements, and project leadership had cast doubt over its future for some time.
A European source familiar with the discussions indicated that both countries are exploring a compromise that would preserve the Future Combat Air System (FCAS) designation for certain remaining elements of the program, including the combat cloud and related technologies, even if development of the core fighter aircraft is discontinued.
While largely symbolic—since FCAS is a broad term used for integrated air combat systems rather than a unique project title—the arrangement could allow France to step away from the fighter component without formally declaring the entire initiative terminated.
Originally launched in 2017 by Emmanuel Macron and former German Chancellor Angela Merkel, the project was intended to become Europe’s premier sixth-generation air combat platform. Efforts to rescue the program continued for months as leaders attempted to bridge differences between the principal industrial partners: Airbus, representing German and Spanish interests, and France’s Dassault Aviation.
Beyond disputes over technical specifications and management authority, France and Germany maintained fundamentally different operational expectations for the aircraft. Merz has publicly questioned whether Germany still requires a crewed sixth-generation fighter and has noted that the Luftwaffe has no need for features such as aircraft-carrier operations or nuclear-strike capabilities.
