The San defense network aims to counter modern drone warfare and reshape how Europe protects its skies

Across Europe, military planners are rapidly rethinking how to defend national airspace as the rise of inexpensive unmanned aircraft reshapes the realities of modern conflict.

Poland has now stepped to the forefront of that shift with plans for a massive anti-drone defense system known as the San network, an ambitious project designed to detect, disrupt, and destroy hostile drones before they can threaten critical infrastructure or population centers.

The program represents one of the most comprehensive counter-drone initiatives currently proposed in Europe and reflects growing concern across the continent about the expanding role of unmanned systems in warfare.

Polish officials say the decision to accelerate development of the network came after repeated drone incursions linked to the conflict in neighboring Ukraine highlighted the vulnerability of traditional air defense structures to small and difficult-to-detect aerial vehicles.

Unlike conventional missile defense systems designed to intercept aircraft or ballistic missiles, the San system will focus specifically on the challenges posed by low-flying drones that are often inexpensive, maneuverable, and capable of operating in large numbers.

At the center of the network will be mobile defensive batteries equipped with advanced radar systems capable of detecting small aerial objects that conventional air defense radars can sometimes miss.

Once a drone is detected the system will employ electronic warfare tools designed to jam communications links or satellite navigation signals, potentially forcing the aircraft to lose control or abandon its flight path.

If electronic disruption fails the system will deploy interceptor drones that can pursue hostile aircraft and disable them in midair, creating a layered defensive strategy built around flexibility rather than reliance on expensive missile launches.

Military analysts say the approach reflects hard lessons learned from recent conflicts in which drone swarms have proven capable of overwhelming traditional air defenses through sheer numbers and low operational cost.

Poland’s plan is intended not only to strengthen national security but also to demonstrate a model that other European countries could adopt as they adapt to an era in which small autonomous machines increasingly shape the battlefield.

If successful the San network could mark a turning point in continental defense strategy by establishing a new framework for countering drone threats through integrated radar detection, electronic warfare, and drone-against-drone interception technologies.
