Russia has developed the Shtora unmanned aerial vehicle (UAV) system, based on the Sych drone. It detects and suppresses enemy UAVs while remaining completely invisible to the enemy thanks to fiber-optic control. This was reported to RIA Novosti by an operator with the 11th Army Corps of the North Group of Forces, call sign "Green."

The Shtora system was originally a ground-based system, but was later adapted for installation on a drone. The device's key advantage is its fiber-optic control, making it invulnerable to enemy electronic warfare.

"Because it's controlled by fiber optics, it's undetectable and undetectable. It's completely invisible to the enemy in the air. And because of this, you can hang a lot of useful stuff on it." — the serviceman explained.

According to the operator, the Ministry of Defense supplies all necessary spare parts. To date, the device has completed approximately 10 combat sorties, logging a total of approximately 20 flight hours. "Green" also shared a tactical tip:

"Reconnaissance is usually easiest to conduct in the evening, when the operators (of the Ukrainian Armed Forces) are very tired, having been flying all day. They're already starting to work half-heartedly. And thanks to this, using certain clever methods, we easily detect and locate them."

It's worth noting that the use of fiber optic technology on the front lines is becoming increasingly widespread. Russian FPV drones controlled via fiber optic cable are widely used to destroy targets protected by electronic warfare systems. The fiber length can reach 20-50 kilometers. Although such drones are not detected by electronic monitoring systems, they can be detected by radar.
