Anyone hoping to be taken seriously in Europe’s defense industry eventually makes a stop at Eurosatory, France’s premier biennial defense exhibition, where governments, military leaders and arms manufacturers gather to showcase the latest technologies and shape the future of European security.
This week’s exhibition at the sprawling Villepinte convention center outside Paris has once again attracted more than 2,000 exhibitors from around the world, reflecting a defense sector enjoying unprecedented demand as European governments dramatically increase military spending in response to growing security threats.
Yet beneath the optimism generated by overflowing order books and promises of hundreds of billions of euros in future defense investment lies growing disappointment.
Only days before the exhibition opened, Europe’s most ambitious effort to strengthen its strategic autonomy suffered what many analysts described as a potentially fatal setback after France and Germany appeared to abandon the concept of jointly developing their next-generation combat aircraft.
The Future Combat Air System (FCAS), long regarded as the centerpiece of European defense integration, is increasingly unlikely to emerge as the fully unified project envisioned when it was launched nearly a decade ago.
French Defense Minister Catherine Vautrin avoided mentioning the troubled program during her opening address at Eurosatory on Monday, but signs continue to mount that Paris and Berlin remain deeply divided not only over FCAS but also over their joint Main Ground Combat System (MGCS), the next-generation battle tank project intended to replace the Leopard 2 and Leclerc.
French President Emmanuel Macron and former German Chancellor Angela Merkel unveiled FCAS in 2017 amid growing concerns following Britain’s decision to leave the European Union and the election of Donald Trump as U.S. president, developments that prompted European leaders to seek greater defense independence from Washington.
At the same time, Paris and Berlin agreed to split leadership responsibilities for two flagship programs. France would oversee development of the sixth-generation fighter aircraft, while Germany would lead the future tank initiative.
Since then, Macron has repeatedly warned that failure of the combat aircraft program could ultimately undermine the tank project as well.
Those concerns intensified over the weekend when Rheinmetall Chief Executive Armin Papperger suggested that France was considering significant reductions in funding for MGCS, although he emphasized that no final decision had been reached.
“I take this warning very seriously,” Ulrike Franke of the European Council on Foreign Relations told German broadcaster Deutschlandfunk.
Franke said the tank project had been encountering increasing difficulties for years and had progressed more slowly than FCAS from the outset.
Germany’s Defense Ministry sought to reassure observers by stating that Berlin and Paris remained committed to advancing MGCS through what it described as a platform-independent approach focused on the program’s core technologies.
Whether that strategy effectively sidelines the original vision of jointly developing a new main battle tank remains uncertain, ministry officials acknowledged Monday.
According to Franke, the difficulties mirror many of the problems that ultimately crippled FCAS.
Germany and France continue to have fundamentally different military requirements that complicate efforts to develop common equipment.
Germany’s armed forces prioritize maximum protection and firepower in preparation for potential high-intensity conflict along NATO’s eastern flank, while France prefers lighter, more mobile armored vehicles capable of rapid overseas deployment.
Industrial competition has proven equally divisive.
German Defense Minister Boris Pistorius recently blamed defense manufacturers rather than politicians for the breakdown of FCAS negotiations.
“At the government level, our hands are tied,” Pistorius said. “The German and French governments genuinely wanted this project to continue.”
Within the FCAS program, French aerospace manufacturer Dassault Aviation has frequently been viewed as a difficult negotiating partner, with prolonged disputes over intellectual property rights and project leadership eventually evolving into a broader struggle for technological dominance in Europe’s future defense industry.
“From the beginning, not everyone was operating on the same wavelength,” said Cedric Perrin, chairman of the French Senate’s Defense Committee.
The battle over control of future technologies has become just as visible in the MGCS program.
Originally, the project was designed around KNDS, the Franco-German joint venture combining Germany’s Krauss-Maffei Wegmann and France’s Nexter.
However, Germany later secured the inclusion of Rheinmetall with strong political backing, significantly altering the project’s balance of influence.
Rheinmetall has openly pursued its ambition of becoming Europe’s largest defense company by 2030, a strategy that has increasingly placed it at the center of Europe’s armored vehicle market.
From the French perspective, the company’s growing role has disrupted an already fragile partnership.
The company first demonstrated its impatience with the pace of political negotiations during Eurosatory four years ago when it unexpectedly unveiled the Panther KF51, presenting it as a viable alternative to the jointly planned MGCS.
The advanced tank has since been aggressively marketed internationally and is reportedly close to securing a major procurement contract from Italy.
From a commercial standpoint, Rheinmetall’s strategy makes business sense.
At the same time, analysts say it reduces incentives to compromise within the Franco-German partnership by offering customers an existing alternative rather than waiting for a collaborative design.
On Monday, KNDS also unveiled a new armored vehicle for the French Army built on the Leopard 2 platform, further illustrating how national industrial priorities are increasingly overtaking multinational cooperation.
The challenges extend beyond Europe’s two flagship land and air programs.
The Eurodrone project, jointly developed by Germany, France, Italy and Spain, has also encountered significant delays and rising costs despite completing its design phase.
Questions continue to grow, particularly within France, over whether the program can still deliver sufficient military value to justify its increasing price tag.
Although Eurodrone has not reached the same critical stage as FCAS or MGCS, defense analysts increasingly view it as another warning about the structural difficulties facing multinational European procurement.
The setbacks come at a time when European governments are committing record defense budgets and publicly emphasizing the need for greater strategic autonomy.
Yet the difficulties surrounding FCAS, MGCS and Eurodrone illustrate that expanding military spending alone cannot overcome long-standing national differences, competing industrial interests and conflicting operational requirements.
As Europe’s defense industry gathers at Eurosatory to present its latest innovations, the exhibition serves as a reminder that technological capability is only one part of building a common European defense. Political consensus, industrial cooperation and shared strategic priorities remain equally essential—and increasingly difficult to achieve.
