Poland is moving forward with the development of what officials describe as potentially Europe’s most sophisticated anti-drone defense system, named San, in direct response to repeated suspected Russian drone incursions into Polish airspace during attacks on Ukraine.
Prime Minister Donald Tusk has called the project “the most modern, intelligent and integrated anti-drone defence system in Europe,” emphasizing the urgent need for a tailored solution to protect Poland’s borders from low-flying, low-cost aerial threats that existing air defense systems struggle to counter effectively.
Retired Polish general Jarosław Gromadzinski, quoted by Polish media, highlighted the strategic necessity:
“Instead of theoretical discussions about future European solutions, we want a system that can be tested and deployed on our border as quickly as possible.”
The push follows several documented incidents in which Russian drones crossed into NATO territory, including a notable breach in September 2025. In those cases, Poland was forced to scramble fighter jets and expend expensive missiles against inexpensive drones — a mismatch that exposed critical vulnerabilities in legacy air defense networks designed primarily for missiles and manned aircraft.
Key Features and Development
The San system is being developed by a Polish-Norwegian consortium comprising:
Polska Grupa Zbrojeniowa (PGZ) — Poland’s state-controlled defense conglomerate
Kongsberg — Norwegian defense technology leader
Advanced Protection Systems (APS) — Polish specialist in radar and counter-drone systems, which has supplied equipment to Ukraine since 2022
Under current plans, the system will consist of 18 mobile anti-drone batteries, each equipped with advanced sensors, radar, electronic warfare capabilities, and kinetic or directed-energy weapons mounted on military vehicles for rapid deployment.
The first operational units are targeted for delivery to the Polish Armed Forces later in 2026, with full system deployment expected within approximately two years.
Financing and Political Debate
The project is expected to draw partial funding from new European Union defense financing initiatives designed to boost arms production across the bloc. However, the financing model has sparked domestic controversy in Poland.
Opposition figures from the conservative Law and Justice (PiS) party, including President Karol Nawrocki, argue that reliance on EU loans could give Brussels undue influence over Polish procurement decisions. They advocate financing the system through domestic resources, potentially including central bank reserves.
Poland has dramatically increased defense spending since Russia’s full-scale invasion of Ukraine in February 2022, now exceeding 4% of GDP — the highest level among NATO members. Warsaw has positioned itself as a key logistics hub for Western aid to Ukraine and has invested heavily in tanks, missile defense, artillery, and other capabilities.
Strategic Implications
Defense industry leaders see the San system as a potential flagship project that could establish Poland as a leading European center for counter-drone technology. The initiative reflects broader NATO concerns about the proliferation of low-cost, mass-produced drones and loitering munitions, which have proven highly effective in Ukraine and pose new challenges to traditional air defenses.
As the war in Ukraine continues and Russian drone operations intensify, Poland’s rapid pursuit of a dedicated anti-drone shield underscores the shifting nature of modern warfare and the urgent need for layered, cost-effective defenses against emerging aerial threats.
