Polish-Ukrainian Startup Develops Low-Flying Drone Radar; Fiber-Optic Command Wires Target

A Polish-Ukrainian startup has developed radar technology designed to detect small, low-flying drones, including those operated via long fiber-optic command wires. The technology addresses a persistent gap in air defense systems across Eastern Europe.

If the startup's claims hold, this creates a procurement opening for Poland, the Baltics, and Ukraine that Raytheon and Northrop Grumman have not yet filled — a gap that favors smaller, agile vendors. Poland's €5.7B Rheinmetall contract (signed June 7) includes Skyranger air defense systems, but Skyranger is optimized for conventional radar targets, not fiber-optic drones.

This suggests Polish procurement planners see a distinct problem set and may dual-source detection. The second-order effect: if Ukraine fields this radar operationally and it proves effective, it becomes a reference design for allied procurement — forcing the major primes to either acquire the startup's IP or accelerate their own low-observable drone detection roadmaps.

WHY IT MATTERS

Ukraine's drone casualty surge (2,000+ Russian losses in six days as of early June) has exposed a critical detection vulnerability: fiber-optic tethered drones evade standard radar and electronic warfare countermeasures because they transmit no RF signature.

This startup radar directly targets that gap, which means any NATO ally or Ukrainian unit fielding it gains a tactical advantage against Russia's growing FPV and loitering-munition arsenal. The mechanism is straightforward: fiber-optic drones are invisible to Doppler and phased-array radar, but they have a physical tether that can be tracked optically or through alternative sensing — if the right hardware exists.

If this system works at scale, it forces Russian drone operators to either accept higher losses or shift to RF-based systems, where existing EW can engage them. Watch for Ukrainian Army procurement announcements or NATO allied trials (Poland, Baltics) within the next 60 days.

WHAT THIS DOESN’T TELL US

Does the radar actually detect fiber-optic tethered drones at operationally useful ranges (5+ km), or is it a laboratory proof-of-concept? What's the false-positive rate against civilian drones and chaff?
