The end of the FCAS (Future Combat Air System) programme marks far more than the failure of an ambitious aerospace project. It represents a setback for the very idea of European strategic integration and raises questions that extend well beyond the defence sector.
For almost a decade, FCAS was presented as the symbol of European strategic autonomy. France, Germany, and later Spain envisioned a system intended to replace the Rafale and the Eurofighter in the second half of the century. It was not simply a new fighter aircraft, but an integrated ecosystem consisting of a sixth-generation platform, collaborative drones, artificial intelligence, advanced electronic warfare capabilities, and a combat cloud capable of fusing in real time data from different sensors and platforms.
The programme’s failure does not, however, stem from technological limitations. Europe possesses the industrial, scientific, and financial capabilities necessary to develop a system of this level. The reasons are essentially political and strategic. The disputes between Airbus and Dassault over industrial leadership, intellectual property, and the distribution of future economic returns merely represented the most visible manifestation of deeper divergences.
For France, FCAS was meant to be the successor to the Rafale and a central instrument of its strategic sovereignty. The new aircraft was designed to operate from aircraft carriers and carry out nuclear missions, fully integrating into the French Force de Frappe. Germany, by contrast, viewed the project as a genuinely European programme, based on a balanced distribution of leadership, expertise, and industrial benefits.
In essence, Paris and Berlin were attempting to build the same system while starting from different conceptions of sovereignty.
The story bears significant historical similarities. In the 1970s, France withdrew from the programme that would eventually lead to the Tornado; in the 1980s, it also left the project that became the Eurofighter Typhoon, choosing instead to develop the Rafale independently. FCAS appears to reproduce the same dynamic: France accepts European cooperation until it comes into conflict with what it considers the core of its strategic autonomy.
The difference compared with the past is that today the geopolitical cost of such choices is much higher.
To understand the significance of this development, it is necessary to return to the origins of European integration. When Jean Monnet and Robert Schuman conceived the European Coal and Steel Community in 1950, France and Germany had emerged from three wars in less than eighty years. Yet they succeeded in pooling precisely the resources that made war possible. The idea was simple and revolutionary: to share economic sovereignty in order to make conflict not only undesirable, but materially more difficult.
Today, the paradox is evident. After decades of integration, with a single market, a common currency, and consolidated supranational institutions, France and Germany are unable to build together the future European fighter aircraft. The question is unavoidable: how was it possible to share coal and steel in the aftermath of the Second World War, yet impossible today to share patents, industrial leadership, and operational requirements?
The answer is probably that the ECSC was born from a clear political determination to pool elements of sovereignty. FCAS, by contrast, stalled because everyone wanted the benefits of cooperation without fully accepting its political costs.
This factor is particularly relevant in light of recent European initiatives aimed at increasing defence investment. One could in fact argue that the very mechanisms developed by the European Union to facilitate higher military spending risk producing the opposite effect from that intended: reinforcing existing fragmentation rather than fostering genuine convergence toward common capabilities and programmes. If a shared vision of strategic interests and European sovereignty is absent, the increase in available resources may simply result in a multiplication of parallel national programmes.
The FCAS case takes on an even deeper significance when viewed through the lens of the debate on European nuclear deterrence. In recent years, particularly after Russia’s invasion of Ukraine, proposals have emerged in Germany aimed at exploring forms of greater integration with the French deterrent, through mechanisms of extended protection or a more structured European involvement in Paris’s strategic thinking.
The failure of FCAS, however, makes this prospect more complex. If France and Germany are unable to share the design of the future platform intended to operate also in the nuclear domain, it becomes difficult to imagine a genuine sharing of the most sensitive dimension of national sovereignty.
Nuclear deterrence is not merely a technology. It is a political relationship based on trust. And strategic trust requires a convergence of interests and visions that the FCAS case demonstrates is still incomplete. France will likely continue to view its deterrent as a national instrument serving European security, but it is unlikely to accept mechanisms that would limit its freedom of decision.
The affair also highlights an industrial and geopolitical consequence. Paris now appears destined to develop the successor to the Rafale independently, while Berlin will have to decide how to preserve its capabilities in the field of next-generation combat aircraft.
In this context, GCAP (Global Combat Air Programme), developed by the United Kingdom, Italy, and Japan, could become the natural pole of attraction for Germany. Should this occur, it would lead to a significant redefinition of Europe’s industrial balance. The Anglo-Italian-Japanese programme would become the leading Western sixth-generation project outside the United States, while France would continue along an autonomous path.
For Italy, this would open a phase of particular strategic relevance. Thanks to the experience gained through the Eurofighter, the F-35, and participation in GCAP, the country would find itself at the centre of the only major multinational Western next-generation programme currently fully operational.
The final lesson of the FCAS story is perhaps the most important. For decades, European integration has been successful in the economic and commercial spheres. Defence, however, requires something different: it requires the sharing of power and, ultimately, of sovereignty.
FCAS did not fail because of a lack of technology, funding, or industrial expertise. It failed because there was no shared vision of European strategic sovereignty. And if Europe cannot build together the aircraft designed to defend it, it will be even harder to build together a deterrent capable of protecting it.
