In a windowless building on the outskirts of Paris, a metal blade the size of a finger glows orange in a furnace. Two engineers in blue overalls lean in, watching a screen where numbers dance at the tenth of a micron. The slightest vibration, the smallest deviation, and the piece is discarded. It’s not jewelry, not a watch mechanism. It’s a fragment of a fighter jet engine, destined to spin at thousands of revolutions per second over a battlefield most of us will never see.

Outside, traffic honks, kids come out of school, life goes on. Inside, France quietly maintains something no other European country still fully controls: the capacity to design and build fighter jet engines from A to Z, down to the finest screw.
The state’s invisible hand has a name: the DGA. And that changes everything.

France’s discreet monopoly on extreme aerospace precision
At the heart of this story is a paradox: France is seen as a country of strikes, gastronomy and heritage, yet it shelters one of the most cutting-edge military-industrial ecosystems on the planet. Behind the Rafale fighter jet, which everyone now recognizes from Ukraine to India, stands a less photogenic but decisive hero: the engine.
And behind the engine stands an institution few people outside defense circles can even name: the Direction générale de l’armement, the DGA.
In 2024, France is the only European country still capable of designing, testing and industrializing a complete fighter jet engine on its soil, with such a degree of mastery and autonomy. No subcontracted brain, no external certification center. A full sovereign chain.
Take the M88 engine that powers the Rafale. Developed by Safran Aircraft Engines alongside the DGA, it is a 2‑ton techno-jewel generating up to 75 kN of thrust with afterburner, spinning at more than 10,000 revolutions per minute in its high-pressure core.
Every turbine blade must tolerate temperature gradients close to the melting point of the metal, vibration shocks and brutal accelerations. The tolerances are so tight that some parts are measured in microns, like human red blood cells.
In the test centers of the DGA, notably in Saclay and Istres, the engines are tortured on benches that simulate icy climbs, desert sandstorms, sudden flameouts. The goal is simple and ruthless: zero surprises, even when a pilot pushes every limit.
Why France and not Germany, Italy or Spain? The answer lies in 60 years of stubborn, sometimes costly choices. Since de Gaulle, Paris has refused to depend entirely on American or British engines. The DGA has kept long-term programs running, even during budget squeezes that would have buried them in other capitals.
Where some European neighbors preferred buying off-the-shelf F‑35s with US engines, France clung to the complicated path of “we’ll do it ourselves, even if it takes longer and hurts”.
That stubbornness created a unique tripod: state (DGA), industry (Safran, Dassault, Thales) and operational feedback from the Air and Space Force. That tripod is what gives France this strange, almost anachronistic status: the last European power truly able to build the whole engine, from first sketch to last bolt.
Inside the DGA machine: how a country builds techno-power
To understand how this works on a daily basis, you have to imagine the DGA less as a dusty administration and more like a conductor. It doesn’t manufacture engines itself. It orchestrates.
The DGA sets the performance bar for tomorrow’s engine down to very concrete things: fuel consumption, infrared signature, noise, resilience in combat. Then it negotiates with industry, finances risky research projects, and supervises the most sensitive tests.
The method is ultra-structured but human. Engineers from the DGA visit Safran workshops, talk with workers, cross-check lab data with pilots’ stories from the Sahel or the Middle East. In reality, nothing replaces the conversation between “those who design” and “those who fly”.
The most common mistake from the outside is to imagine a military-industrial monster that advances blindly, obsessed with tech records. Inside, conversations are much more down-to-earth.
An engineer will talk about the effort needed for a mechanic on a runway at night with frozen fingers. A test pilot will describe that half-second of fear when an engine sucks a bird at low altitude. A program manager will admit that every extra kilo of metal is a headache for logistics and fuel costs.
We’ve all been there, that moment when a perfectly designed object becomes useless in real life because the person who built it never spoke to the person who uses it. The DGA’s job is mostly to avoid that.
This is where a tension appears, sometimes whispered in corridors, sometimes stated publicly.
“Every time we push the limit of what our engines can do, we open two doors at once,” confided a former DGA engineer. “One toward better protection for our pilots, the other toward more destructive potential. And no algorithm can tell you where to stop.”
To navigate that, the DGA relies on a few internal “compasses”:
- Long-term strategic vision, beyond the next election
- Red lines on export (certain technologies never leave French soil)
- Continuous dialogue with the armed forces actually using the equipment
- Ethical and legal frameworks, often updated after each conflict
Let’s be honest: nobody really reads the fine print of these military doctrines. Yet that’s exactly where the line between technological miracle and dangerous escalation is quietly drawn.
Between pride and unease: what this means for the rest of us
This French “monopoly” on fighter jet engines in Europe is a source of national pride for many engineers, politicians and even ordinary citizens fed up with seeing Europe depend on US or Chinese tech.
It also raises a more intimate question. How do we feel about living in a country capable of producing objects that are both masterpieces of precision and tools of war? It’s easy to cheer when Rafales exported to India or Egypt land big contracts and jobs. It’s less comfortable when you imagine the downstream use of those engines in a real combat situation, somewhere far from Europe’s safe cafés.

FAQ:
- Is France really the only European country that can build complete fighter jet engines?Yes, in terms of full sovereign capability covering design, testing, certification and industrialization of a modern combat aircraft engine on national soil, France stands alone in Europe. Other countries participate in joint programs or rely on US or British powerplants.
- What exactly does the DGA do in engine programs?The DGA defines performance and safety needs, funds high-risk research, supervises test centers, validates technical choices and guarantees that critical technologies remain under French control, even when exported.
- Are these technologies used only for the Rafale?No. The know-how developed for the M88 feeds into transport aircraft engines, drones, helicopters and, tomorrow, the future Franco-German-Spanish fighter under the SCAF/FCAS program, where France’s engine expertise is central.
- Does this contribute to an arms race in Europe?
