FCAS AND THE CRISIS OF EUROPEAN DEFENCE COOPERATION – Cristina Di Silvio

Introduction

The crisis of the Future Combat Air System (FCAS) represents far more than an industrial dispute between aerospace companies. It constitutes an indicator of the structural difficulties that continue to characterize the process of European integration in the field of defence. The progressive deadlock affecting the programme and the decision to suspend the joint development of the new European sixth-generation fighter aircraft demonstrate how the strategic ambitions of the European Union continue to confront the persistence of divergent national interests.¹

Launched in 2017 as a symbol of Franco-German cooperation, the Future Combat Air System (FCAS) was intended to become the cornerstone of Europe’s future air superiority. The project was conceived as an integrated system consisting of a next-generation combat aircraft, unmanned platforms, advanced sensors, and a digital combat network known as the combat cloud.²

Strategic Autonomy and Industrial Sovereignty

The FCAS experience highlights one of the principal contradictions within the current European defence debate. Although Member States share the need to strengthen the Union’s technological and military capabilities, they remain reluctant to relinquish control over their respective industrial sectors.

From this perspective, European cooperation continues to encounter difficulties in reconciling political integration with economic sovereignty.³ The construction of genuine European strategic autonomy would require not only common investments, but also the sharing of technological expertise and national industrial capabilities.

The dispute between Airbus and Dassault Aviation has gradually acquired significance beyond the simple governance of the programme. Disagreements regarding project leadership, the allocation of responsibilities, and intellectual property rights transformed FCAS into a testing ground for competing visions of European industrial cooperation.⁴

Two Visions of European Defence

The tensions surrounding the programme also reflect different strategic approaches adopted by France and Germany.

For Paris, FCAS represented an instrument for achieving military autonomy and strengthening European strategic sovereignty. French strategic culture traditionally places considerable importance on the ability to operate independently and maintain national control over critical technologies.

Berlin, by contrast, has favoured an approach more closely oriented towards interoperability within NATO and the sharing of industrial responsibilities among partners.⁵ This divergence in strategic outlook contributed significantly to disagreements over the programme’s priorities.

The inability to overcome these differences progressively weakened the political dimension of the project. The FCAS crisis demonstrates how the construction of a common European defence still depends upon the existence of strategic convergence, which, at present, remains incomplete.⁶

Comparison with Alternative Models of Cooperation

The significance of the FCAS case becomes particularly evident when examined within the broader context of next-generation aerospace programmes. Parallel to the difficulties experienced by FCAS, the Global Combat Air Programme (GCAP), involving Italy, the United Kingdom, and Japan, continues to advance through its development phases.

Although operating within different geopolitical and institutional contexts, the two programmes reflect distinct models of international cooperation.

While FCAS was conceived as an expression of European integration, GCAP is based upon a more flexible decision-making structure and a more clearly defined strategic convergence among its partners. This difference illustrates how the effectiveness of industrial cooperation depends not solely on political ambition but also on the capacity to establish shared and sustainable decision-making mechanisms over the long term.

Comparative experience suggests that the success of technologically complex programmes requires a clear definition of industrial responsibilities and a balanced distribution of economic and strategic benefits among participating partners.

The FCAS Crisis in the Contemporary Geopolitical Context

The crisis of the programme occurs during a period of profound transformation within the international order. The return of great-power competition, the growing instability of the European security environment, and the necessity of strengthening the continent’s military capabilities have returned defence to the centre of the European political agenda.⁷

Russia’s invasion of Ukraine and the deterioration of the European security landscape have further reinforced the perception that autonomous deterrence capabilities and advanced industrial capacities are essential.

Within this context, the failure of FCAS’s central component assumes a significance that extends far beyond the aerospace sector. It represents evidence of the difficulties encountered by Europe in constructing common instruments of strategic power within an increasingly competitive international system.⁸

The case demonstrates that the availability of financial resources and the existence of shared political objectives are not sufficient to guarantee the success of particularly complex multinational projects. The presence of a common strategic vision and effective governance mechanisms remains indispensable.

What Future for European Defence Cooperation?

The FCAS crisis does not mark the end of European defence cooperation; rather, it highlights the need to rethink its methods and instruments. The continuation of certain programme components, such as the combat cloud and unmanned systems, demonstrates that opportunities for collaboration still exist.

Nevertheless, the suspension of the common sixth-generation fighter project confirms that European industrial and strategic integration remains an unfinished process.⁹

At a deeper level, the FCAS case illustrates that strategic autonomy cannot be built solely through political declarations. It requires a stable convergence of industrial interests, shared decision-making capabilities, and a common vision of European security.

Until these conditions are fully achieved, every ambitious programme of European cooperation will remain exposed to the risk of implementation crises, with potential consequences for Europe’s credibility as an autonomous strategic actor within the international system.
