The Future Combat Air System, a planned €100 billion sixth-generation fighter jet, was supposed to be the flagship proof that France and Germany could build serious military hardware together. Instead, it became a case study in why they often can't. Chancellor Friedrich Merz told President Emmanuel Macron in early June that Germany would not continue jointly developing a crewed aircraft under the program, formally ending the manned-fighter component after nine years of on-and-off negotiation.
The core dispute was industrial, not political: Dassault Aviation, France's manufacturer, argued it had the expertise to build a combat aircraft "from A to Z" and wanted to lead; Airbus, representing German and Spanish interests, insisted a project of this scale needed a genuinely balanced partnership. Neither side moved far enough to save it.
With FCAS dead, Germany is now eyeing the rival Global Combat Air Programme, the UK-Italy-Japan effort that has a working three-nation governance structure and, unlike FCAS, has already produced demonstrator hardware. Leonardo's chief executive has said Germany would be a valuable partner. But Japan has been reluctant to admit new members for fear of delaying GCAP's 2035 in-service target, and Berlin has made clear it wants a role proportional to what it would pay in — not a junior seat at someone else's table.
The FCAS collapse lands alongside a broader shift in how Berlin is approaching European defence cooperation. German commentary has increasingly framed the country's own procurement decisions — from Tomahawk missile purchases to its defence posture generally — around political instability in Paris, which has made Germany warier of tying its military planning too closely to French timelines. Whether or not that reading is entirely fair to Macron, the practical effect is the same: Europe's two biggest military powers are now planning around each other rather than with each other on hardware.
The instinct behind FCAS — that Europe should stop buying American and start building its own high-end weapons jointly — hasn't gone away. But the mechanism for doing it, at least for fighter jets, just failed. A Franco-German ministerial council expected around 17 July will settle what remains, most likely limited to the "combat cloud" networking architecture that both sides always found easier to agree on than an actual airframe. If Germany ends up in GCAP and France goes its own way, Europe will have spent nine years and considerable political capital arriving at exactly the fragmented, multiple-program outcome that "strategic autonomy" was supposed to avoid.
