PARIS — Europe’s largest land warfare exhibition opened Monday outside Paris under a cloud of urgency, as government officials, arms manufacturers and military delegations gathered to discuss a question that has leaped from the realm of theory to reality: How fast can the West prepare for the next major war?
Eurosatory 2026, held at the Paris-Nord Villepinte exhibition center through Friday, is taking place in a radically different environment from the defense trade shows of the pre-Ukraine war era.
With Russia’s full-scale invasion in its fifth year, European armies are racing to rebuild depleted stockpiles, and doubts about the strength of U.S. security guarantees have pushed the continent into a more aggressive rearmament drive.
Organizers say the show brings together more than 2,100 exhibitors from 65 countries, more than 330 official delegations from 93 countries and hundreds of new defense products.
Industry reporting has put the expected number of exhibitors even higher, above 2,600, making this one of the largest editions of the biennial event.
The scale of the show reflects the current mood in European capitals: The question for many governments is no longer whether they should spend more on defense, but how and on what technologies that money ought to be spent.
Charles Beaudouin, chief executive of Eurosatory organizer COGES Events, described this year’s edition as shaped by “rising perils.” He warned in a recent interview with Defense News that the Paris show may be a “last chance” for European countries to buy existing systems that can be delivered before a possible confrontation with Russia.
That blunt assessment has given this year’s fair a very different feel from prior editions. Eurosatory has long been a marketplace for tanks, artillery, armored vehicles, radars, missiles and military electronics.
This year, it is also a test of whether Europe’s defense industry can shift from boutique production to something closer to a war economy.
Ukraine is central to that shift.
Once seen largely as a recipient of Western aid, Kyiv is arriving in Paris as a defense and armaments-tech power in its own right. Ukrainian companies are presenting drones, electronic warfare systems, ground robots, long-range strike technology and battlefield software tested daily on the battlefield, and beyond it.
Ukraine’s private defense industry is being represented under the national brand ZBROYA, with firms showing systems developed through direct combat experience.
Ukraine’s overall defense presence has expanded sharply compared with previous editions, reflecting Kyiv’s ambition to become a global defense and security supplier.
The Ukrainian pitch is simple — and powerful: the efficiency and lethality of its weapons isn’t theoretical, as they have been tested against Russian forces, and, increasingly, against Russia’s economic and oil infrastructure.
This is Ukraine’s main selling point, as many European militaries are trying to absorb the lessons of Ukraine’s battlefield at speed. The war has shown the centrality of drones, electronic warfare, counter-drone systems, low-cost long-range strikes, rapid software updates and shorter targeting cycles.
It has also shown that high-end platforms remain vulnerable if armies lack ammunition, spare parts and industrial depth.
France is among the countries drawing direct lessons from the Ukrainian battlefield. French defense officials are working on a Ukraine-inspired “kill web” designed to connect sensors, commanders and weapons more quickly, drawing comparisons to Ukraine’s Delta battlefield management system.
The goal is to reduce the time between detection and strike in a battlespace increasingly saturated with drones, jammers and artillery.
Ukrainian officials say the shift is only beginning.
Danylo Tsvok, head of Ukraine’s defense ministry artificial intelligence center, has described AI as part of a “new paradigm of warfare,” predicting a future “war of operating systems” in which battlefield advantage comes from data, speed and coordination as much as from traditional firepower.
Still, the lesson from Ukraine is not purely technological. French Army Chief of Staff Gen. Pierre Schill has warned against reducing the war to a showcase for drones and AI. The conflict has also brought back trenches, artillery duels, urban fighting, mass casualties, logistics and attrition.
That combination of old and new warfare is now visible across the show floor. Counter-drone systems sit alongside armored vehicles and self-propelled artillery guns. AI tools are displayed near artillery shells. Long-range missiles and battlefield networks compete for attention with ammunition production lines and military trucks.
European industry is also looking beyond the traditional defense sector for scale.
Renault and Thales announced a partnership to develop a hybrid 4×4 military vehicle, the 4 TROOP, which is being presented at Eurosatory. The project points to a wider effort to use civilian industrial capacity, especially from the automotive sector, to accelerate defense production.
The financial world is also moving closer to the arms industry.
Eurosatory is hosting a section dedicated to banks and investors, an indication that defense is again being treated in Europe as a mainstream strategic industry rather than a politically awkward niche.
The United States remains heavily present, with roughly 180 American companies expected at the show. But the American role is changing: While European governments still want U.S. weapons — especially air defense, missiles and high-end electronics — they’re at the same time trying to reduce dependency on Washington after repeated warnings that American stockpiles and support cannot be taken for granted.
The fair is not free of controversy.
France has restricted Israel’s official participation, barring Israeli companies from displaying offensive weapons and denying Israel a national pavilion. Israeli officials have condemned the move as politically motivated, adding another diplomatic dispute to a show already shaped by the ongoing wars.
For all the politics, the main takeaway from this year’s edition of Eurosatory is that Europe appears committed to upgrading and updating its armed forces, while Ukraine is selling some hard-earned experience and battle-tested technologies.
The arms industry is now being asked to deliver at a speed it has not known since the Cold War. The question in Paris this week is whether that mobilization is happening fast enough.
