The face of war has changed. In recent years, modern conflicts have been marked by the emergence of new threats from the sky: low-cost drones. Used on a large scale on the Ukrainian front, in the Middle East or by paramilitary groups, these cheap drones - often from the civilian market - are transforming military strategies at an unprecedented speed.
Easy to produce, affordable and adaptable, these light aircraft have established themselves as breakthrough tactical tools, capable of saturating defenses, harassing armored units or gathering intelligence with complete discretion. But this success also raises questions: what technical compromises are acceptable in the face of operational pressure? How can governments guarantee their technological sovereignty in this new aerial landscape?
The rise of low-cost drones in modern warfare
The low-cost drone is no longer a gadget. It has become a weapon. In current conflicts, particularly in Ukraine and Syria, these devices are used by the hundreds, sometimes on a daily basis. Their roles are many and varied: reconnaissance, fire adjustment, surveillance, attack, diversion, saturation...
This explosion in usage can be explained by three main factors:
- Hardware accessibility: most of the components used in these drones are freely available on the civilian market. A simple flight map, FPV ESC and GPS module are all that's needed to fly a low-cost machine.
- Ease of assembly: thanks to 3D printing, Open Source plans and online tutorials, it's possible to assemble an operational drone with basic tools, sometimes in just a few hours.
- Low unit cost: at 500, 800 or 1500 euros, a low-cost drone can be sacrificed with no major financial consequences. This volume logic creates a devastating attrition effect.
In short, it's no longer technology that dictates warfare, but accessibility. For less than the price of a guided grenade, we can produce a vector capable of striking, filming, localizing or disrupting.
Tactically formidable performance
While these drones are technically simple, they are tactically effective. Their main advantage? Being where you least expect them.
Stealth through simplicity
Unlike planes or helicopters, a low-cost drone flies low and slow, and produces a thermal or radar signature that is difficult to detect. Some are even capable of slipping through openings or into buildings, where no conventional craft can penetrate.
Mission versatility
Reconnaissance, artillery guidance, delivery of explosive charges, jamming, sensor saturation... The low-cost drone is versatile. It can be sent as a scout, a kamikaze, or used to divert attention while a human group maneuvers.
The mass effect
The great novelty of this technological war is the democratization of the sky. When a group can launch 50 drones at a cost of €1,000 to saturate an air defense system, mass effect becomes a weapon. The cost/effectiveness ratio becomes terribly asymmetrical.
That said, these drones do have their limitations: fragility, limited autonomy, vulnerability to wind, jamming, frost or rain, lack of armor, unsecured communication, etc. Their effectiveness is therefore based on environment and volume, not individual robustness. Their effectiveness therefore depends on the environment and volume, not on individual robustness.
Strategic challenges and the armed forces' response
Faced with this new situation, governments need to adapt their strategy. It's no longer just a question of producing long-range combat drones costing several million euros. We must also integrate the industrial, logistical and electronic dimensions of combat.
Western technological vulnerability
Today, almost all the electronic components used in low-cost drones come fromAsia, mainly China. This includes :
- flight maps (Betaflight, Pixhawk, etc.) ;
- FPV ESCs;
- brushless motors;
- BEC controllers, radio receivers, GPS modules, IMUs.
This dependence is not without consequences: trade tensions, embargoes or export restrictions can paralyze supply chains at any time. Worse still, components can be compromised or falsified, posing major cybersecurity problems.
Sovereignty and relocation: towards a made in France industry
To guarantee an autonomous defense capability, initiatives are being developed in Europe and France around the relocation of technological building blocks. This is where companies like Drone Français play a key role.
Drone Français designs and manufactures critical components in France:
- powerfulESCs (up to 65 A) for tactical and FPV UAVs;
- from flight maps reliable, modular and compatible with open standards;
- voltage regulators and power supply modules adapted to military requirements.
By producing these essential spare parts locally, France strengthens its industrial sovereignty and ensures complete control of the value chain. It also enables components to berapidly adapted to specific requirements (encryption, redundancy, resistance to shock or interference).
A mixed doctrine: quality, quantity, responsiveness
Western armies now tend to adopt a mixed approach:
- High-end drones: used for strategic, high-precision or long-range missions;
- Optimized tactical drones: inspired by low-cost drones, but with ruggedized, secure, reliable and traceable components.
The aim is to industrialize accessible, yet sovereign and interoperable solutions, capable of responding to intense, rapid and dispersed conflicts.
Low-cost UAVs have demonstrated that they can change the rules of the military game, with low cost and immediate effectiveness. But this tactical agility reveals a strategic vulnerability: as long as key components are imported, the defense chain remains fragile.
The answer lies in rebuilding a sovereign industry, from technology bricks to complete UAVs. In France, players such as Drone Français are showing that it is possible to design high-performance, modular electronic components that are independent of foreign markets.
Because dominating tomorrow's airspace will depend not just on the size and power of drones, but on mastering the invisible components that make them fly.
