Sky Fortress (drone defense system)

Sky Fortress is an acoustic early-warning drone defense system developed in Ukraine for detecting Shahed-136 drones initially.

Acoustic sensors consisting of mounted microphones and smartphones on poles, AI and machine learning enable the detection of approaching low-flying drones, which produce a characteristic sound.[1] The system is significantly cheaper than existing air defense systems.[2][3]
