Summary
A handheld drone-detection device resembling Ukraine's Obriy 1.3 was seen at a U.S. Army training exercise in Fort Irwin, California. The device, identified as 'BlackSky Guardian-1,' was used during an October 2025 training rotation. The Obriy 1.3, developed by Kara Dag Technologies, detects various drones and has been deployed in Ukraine since 2023. It can identify drone signals up to 2 kilometers away and provides directional information. The U.S. Army has not confirmed the device's identity or its link to the Ukrainian system, as original markings were obscured. This development aligns with the Army's focus on counter-drone technologies amid lessons learned from the Ukraine conflict. Kara Dag Technologies has partnered with Anduril Industries to enhance drone detection capabilities. The U.S. Army's recent exercises reflect an increasing integration of drone warfare tactics into military training. Key Points: • A device resembling Ukraine's Obriy 1.3 was spotted at a U.S. Army training exercise. • The BlackSky Guardian-1 can detect drones up to 2 kilometers and offers directional data. • Kara Dag Technologies is collaborating with Anduril Industries to improve drone detection technology.
Detailed Analysis
**Impact** The U.S. Army is integrating Ukrainian-developed drone detection technology into training exercises at Fort Irwin, California, indicating a shift toward adopting battlefield innovations from the Ukraine conflict. This affects U.S. military operational capabilities, particularly in counter-unmanned aerial systems (C-UAS) and drone warfare tactics. The technology’s deployment may enhance detection and defense against small drones within a 2-kilometer range, potentially improving force protection and situational awareness in training and future combat scenarios. **Technical Details** The device observed, labeled “BlackSky Guardian-1,” closely resembles the Obriy 1.3 drone detector developed by Ukrainian company Kara Dag Technologies. The system detects FPV, DJI, and Autel drones across multiple frequency bands, providing directional detection, vibration alerts, spectrum analysis, and analog FPV video interception. The device’s markings were obscured, preventing definitive identification. The Obriy 1.3 is integrated with a drone radio-frequency signature database, now partnered with U.S. defense firm Anduril Industries for software and defense integration. No malware, CVEs, or attack infrastructure details were provided. **Recommended Response** Defenders should monitor for the presence of advanced multi-band drone detection systems and evaluate their integration into existing C-UAS protocols. Training units should incorporate detection and response drills using similar technologies to improve counter-drone readiness. There are no specific patches or IOCs available; therefore, focus should remain on operational awareness and adapting tactics to include RF signature analysis and drone signal interception capabilities.
