Summary

On April 22, 2026, Poland conducted operational tests at the Central Air Force Firing Range in Ustka under its Eastern Shield program, evaluating seven acoustic drone detection systems, including the Norwegian Discovair G2+ by Squarehead Technology. The Discovair G2+ uses directional microphones and AI to detect drones by their sound signatures, addressing limitations of conventional RF and radar-based detection. Poland allocated 6.86 billion zloty in 2026 for drone and counter-drone system procurement. The tests are part of a broader innovation push initiated in 2025, with over 715 technology submissions and 36 tested solutions so far. The Eastern Shield program aims to secure Poland's strategically sensitive eastern border with Belarus and the Russian exclave of Kaliningrad, emphasizing domestic development of tailored technologies.

Classification

Confidence: High

This report details defensive technology testing and procurement by Poland to counter drone threats along its eastern border, indicating preparation and enhancement of defense capabilities rather than hostile aggression.
