On a dull, overcast morning at the DGA engine test facility in Saclay, just outside Paris, the ground begins to tremble before anything comes into view. Technicians in faded blue overalls move between computers and heavy cables, coffee cups in hand, with the calm, deliberate rhythm common around dangerous machines. Behind a thick glass barrier, a Rafale engine bursts into life, bolted to a steel test bench. The sound doesn’t simply fill the space—it presses into your chest. One tiny defect, one misaligned blade, and the entire system could self-destruct in a fraction of a second.
Yet no one shows fear. What you see instead is pure concentration.
A young engineer steps closer to the glass, eyes fixed on the exhaust flame. “Listen,” she says. “You’re hearing the only fighter engine in Europe that we can build entirely on our own.”
She means France.
And she’s pointing to something most people still overlook.
France’s Understated Air Power Advantage
From a distance, Europe appears formidable: Airbus dominating civil aviation, multinational fighter programs, shared budgets, and layered cooperation. But when you focus on the most sensitive component of a combat aircraft—the engine—the picture changes dramatically. France stands almost alone.
The Rafale’s M88 engine, developed by Safran under continuous DGA supervision, is the only modern European fighter engine whose complete design, testing, and industrial control remain entirely within national borders. No U.S. licenses. No compulsory British, German, or Italian partners. From the digital model to the final turbine blade, every decision can be made in France.
This isn’t about pride. It’s about strategic leverage.
Step into a DGA test hall and you won’t find a polished showroom. Instead, there are thick concrete walls stained by exhaust, aging analog gauges sitting beside ultra-high-resolution screens, and cardboard coffee cups resting on racks of sensors worth millions. At the center sits a silver cylinder that seems modest compared to the thunder it produces: an M88, the living core of the Rafale.
During test campaigns, engineers intentionally push the engine far beyond anything a pilot would attempt. Sudden throttle changes, simulated bird strikes, sand ingestion, violent temperature swings. Cameras track a single blade—just centimeters long—spinning at tens of thousands of revolutions per minute.

If that blade fails, it’s not just a component that’s lost. It’s an aircraft. A pilot. A mission. And a nation’s credibility.
This is where the DGA’s role becomes tangible. It is not merely an agency that signs off on contracts. It is the state’s analytical core for defense. For the M88—and for the future engine of the Franco-German SCAF fighter—the DGA defines extreme requirements, validates bold concepts, and relentlessly tests prototypes until only what truly works remains.
Without DGA laboratories and test benches, Safran would still be a major engine manufacturer. But France would not be the only European nation capable of mastering the entire chain—design, materials, production, testing, certification, and operational feedback—fully under national control.
That subtle distinction—who truly owns the final bolt—becomes decisive when crises emerge.
The Microscopic Precision Behind a French Fighter Engine
To grasp what makes this capability so rare, you have to zoom in to the millimeter scale. Building a fighter engine isn’t about raw thrust alone. It’s about tolerances so exact that a human hair would seem thick by comparison. The DGA and Safran operate like watchmakers wielding a flamethrower.
In one workshop, a technician fine-tunes the cooling holes of a turbine blade. Each opening is barely visible, laser-drilled into metal engineered at the atomic level to survive extreme heat. The DGA’s task is to define precisely how hot “extreme” is allowed to be—and to measure it without compromise.
Here, precision is not optional. It’s the reason a pilot can engage full afterburner and trust the engine to respond flawlessly.
Europe is full of talented engineers, but very few nations retain full sovereignty across the entire chain. The Eurofighter Typhoon’s EJ200 engine, for instance, is a multinational effort. Each country controls specific modules, software elements, or expertise. It’s powerful—but not fully governed by any single capital.
France chose a different path. From the Mirage series to the Rafale, the state consistently invested in a national engine lineage, even when budgets were tight and critics argued cooperation would cost less. The DGA pushed for domestic advances in materials, aerodynamics, digital simulation, and testing infrastructure, maintaining facilities that many considered excessive for a mid-sized power.
Most governments compromise control to reduce costs. France did not. That persistence is exactly why the country now occupies a unique position in Europe.
Recent geopolitical shocks have suddenly highlighted this long-term decision.
As tensions rise, export controls tighten and supply chains become political tools, dependence on foreign approvals turns into vulnerability. Some European aircraft cannot be sold or upgraded without external authorization because a single critical component or line of code originates abroad.
With the Rafale and its M88 engine, France negotiates directly with partners such as India, Egypt, or Greece. The DGA can authorize adaptations, new variants, and long-term support without external consent. France still cooperates internationally, but when it matters most, it retains the keys to its engines.
That is the quiet, technical meaning of sovereignty in 2026.
How the DGA Preserves Its Technological Lead
Maintaining this level of mastery requires constant motion. The DGA operates a continuous feedback loop linking laboratories, test centers, and operational units. Rafale squadrons deployed in desert environments report engine wear data. That information feeds into DGA analysis teams, which refine test protocols—sometimes down to a single software adjustment or a new protective coating.
The cycle never stops. The DGA acts as referee and archivist, recording every failure, micro-crack, and anomaly. Safran may propose a new alloy or a 3D-printed component to improve performance. The DGA responds by recreating the harshest possible conditions, simply to discover where and how it breaks.
The objective is straightforward: no surprises at 40,000 feet.
From the outside, this process can appear rigid. From within, engineers describe it differently. Many recall late-night tests where data suddenly spikes and everyone waits, silent, as systems strain. In those moments, shortcuts vanish. Reality takes over.
States often make the same errors: overreliance on foreign partners, neglect of unglamorous test infrastructure, and allowing rare expertise to fade without transmission. The DGA actively avoids these traps. It funds obscure doctoral research on high-temperature fatigue and advanced alloys, and it preserves databases of test results older than many of its interns.
From afar, it looks slow. Up close, it’s the only way to preserve such a complex craft.
“People see the Rafale engine as a product,” a DGA engineer explains. “In truth, it’s a living ecosystem of skills. Stop maintaining it for five years, and you’re no longer a nation that can build one. You’re just a nation that can buy one.”

A Discreet Monopoly That Challenges Europe
Once you understand the machinery behind a fighter engine’s roar, Europe’s industrial map looks different. One country—France—retains a complete, proven ability to design, build, and certify a modern fighter engine independently. Others contribute and innovate, but not with the same level of sovereign control.
This reality raises difficult questions. Should Europe centralize everything into a few massive programs, accepting new dependencies? Should each nation preserve fragments of autonomy at higher cost? Or does the French model—a long-term national investment anchored by a strong state actor like the DGA—offer a template worth considering?
There are no simple answers. What is clear is that this technical detail will heavily influence future combat systems, export freedom, and political decision-making.
When a Rafale flies over Paris during the 14 July parade, there is a quiet message embedded in that engine’s thunder. It speaks of a country that chose, decades ago, to understand every turning blade—and to never let that knowledge slip away.
Key Takeaways
- France’s unique position: The only European nation fully controlling the fighter engine chain from design to testing
- The DGA’s central role: Defining specifications, funding research, enforcing extreme testing, and preserving expertise
- Strategic impact: Freedom to export, upgrade, and support engines without foreign approval
