Striking Drones: Autonomy and Precision

Over recent months, “kamikaze drones” have become a frequent term in media and online discussions to describe a type of unmanned system capable of precise strikes on enemy targets. The phrase is attention-grabbing, but doesn’t fully capture the technical and operational sophistication of these platforms. Rather than acting recklessly, they are engineered to achieve surgical effects with maximum efficiency.

The conflict in Ukraine has accelerated the development and deployment of these systems, highlighting their tactical and strategic significance. What was once considered a niche technology has now emerged as a key factor in multidomain operations. Current debates focus on autonomous loitering munitions, drone swarms, GNSS-denied navigation, cost-effective advanced sensors, and portable platforms able to neutralize high-value targets.

This evolution has spurred national and international programs — including initiatives under the European Defence Fund — aimed at fostering sovereign industrial capabilities. Below, we outline the main categories, operational uses, and core concepts to clarify this rapidly evolving landscape.

A Necessary Typology: Not All UAVs Attack the Same Way

Unmanned aerial systems used offensively generally fall into two broad families: loitering munitions, which are expendable and destroyed with their target and combat UAVs (UCAS), recoverable and reusable platforms that can return, rearm, and fly again.

Both categories share the ability to carry lethal payloads and operate remotely or autonomously.

• Short range (5–10 km): lightweight, low-cost systems deployable by small units or even a single operator.They are typically employed against infantry or light vehicles, often guided by live video feeds. To counter jamming, some use fiber-optic tethers instead of radio links. Warheads usually range from 0.5 to 2 kg.
• Medium range (10–50 km): more capable platforms, suited for striking artillery positions, convoys, or mobile radars. These systems often integrate with C2 networks, use EO/IR sensors for day/night targeting, and carry warheads between 4 and 10 kg.
• Long range (50–200+ km): designed for operational and strategic depth. Though less precise individually, they are devastating in coordinated salvos, forcing the enemy to expend expensive air defence systems on low-cost drones. Their warheads weigh around 40–50 kg.

Looking Ahead: Where These Systems Are Heading

Despite their diversity, all UAVs share a technological roadmap pointing towards:

• Greater autonomy in navigation, detection, and even target engagement, raising ethical and legal challenges. Documented cases already hint at lethal autonomy without human intervention. In this field, it is also relevant to consider the GNSS-independent precision navigation, combining INS, computer vision, radar, and opportunistic signals to ensure resilience in denied or contested environments.
• Autonomous coordination of heterogeneous swarms, enabling multiple UAVs to operate in formation, maintain safe separation, and execute complex manoeuvres with minimal operator input.
• Scalable, low-cost production, with designs optimized for mass manufacturing, faster development cycles, and alignment with operational tempos. Effective deployment requires not only advanced air systems but also logistics, supply chains, operator training, and maintenance to sustain large-scale operations.
• Modular, open architectures to support sensor, payload, and communication interoperability, including open standards for multinational integration.
• C4ISR integration, connecting drones as networked nodes to share intelligence and coordinate strikes in real time.

These lessons are being applied directly from battlefield experience, especially in Ukraine, highlighting the operational value of resilience, autonomy, and coordination.

Another key feature is 4D Trajectories, which allows UAVs to reach waypoints or engage targets at exactly the planned time. Combined with advanced onboard intelligence, this enables synchronized attack manoeuvres, time-critical missions, and precise coordination of multi-platform operations.

Finally, mission security is ensured through automatic secure memory deletion, preventing sensitive data from falling into adversary hands. At UAV Navigation – Grupo Oesía, we deliver guidance, navigation, and control systems that provide the precision, autonomy, and resilience required for modern battle spaces, ensuring reliable, sovereign, and advanced UAV solutions for today and tomorrow.

Europe’s Dilemma: Emerging Capabilities, Persistent Dependence

The war in Ukraine has exposed Europe’s reliance on foreign suppliers for advanced unmanned and loitering munitions. While several European initiatives have been launched to develop domestic capabilities, many programs are still in their early stages and depend heavily on non-European components, including sensors, guidance systems, communications modules, and energy sources. This dependency highlights a broader vulnerability: even when platforms are designed and assembled in Europe, critical technologies are often imported, leaving the continent exposed to supply chain disruptions or geopolitical pressures.

Developing a fully resilient and sovereign industrial base is therefore one of Europe’s top strategic priorities. Achieving this requires not only investing in research and development but also creating robust manufacturing ecosystems, resilient supply chains, and interoperable technologies that allow European systems to operate independently. Beyond hardware, it also entails cultivating a skilled workforce capable of designing, building, and maintaining advanced unmanned platforms. In a rapidly evolving context, strengthening domestic capabilities is essential to ensure that Europe can field, sustain, and scale advanced UAV systems without reliance on external suppliers.
