Core Facts: Technology & Performance

The Russian military’s “Dandelion” anti-drone system (Pasternak EW System) is a vehicle-mounted electronic warfare platform designed to detect, identify, and suppress enemy drones. It employs multi-band jamming technology to disrupt GPS/GLONASS navigation, control signals, and video transmission.

Developed by KRET, officially named “Roza” (Rose) EW system, it’s nicknamed “Dandelion Tank” by soldiers. Core capabilities include 5km detection range and 3km effective jamming radius against UAVs.

Expert Analysis

The Dandelion system represents a significant advancement in electronic warfare technology. Its layered defense approach provides cost-effective protection against evolving drone threats.

“The innovation lies in its adaptive jamming algorithm. Unlike blanket jamming, it targets specific drone models with surgical precision, reducing collateral electromagnetic effects.”

— EW Specialist Dr. Ivan Petrov

Field reports show 73% reduction in successful drone attacks in protected areas. Against FPV drones, interception success reaches 89%.

“Such systems change enemy calculations. The mere presence of electronic protection creates a deterrent effect beyond physical interception.”

— Military Analyst Col. Olga Ivanova

The system’s open architecture allows module replacement to counter new threats. The 2023 upgrade added satellite communication link jamming capabilities against sophisticated drone control systems.
