EW SYSTEM "HAMMER 21-27"

The "Hammer 21-27" EW system is a highly effective electronic warfare system designed for rapid disruption of communication between unmanned aerial vehicles and their controllers. Thanks to its multi-frequency operation and compact design, it is an ideal solution for tactical use in active combat conditions.

MODEL FEATURES

The system covers the key control frequencies of modern UAVs — 2100–2300, 2300–2500, and 2500–2700 MHz. Output power is 100 W (+20 / −10)% per band, ensuring stable signal suppression. Continuous operating time is at least 120 minutes, sufficient for most operational tasks. Suppression range is at least 70 meters, and the weight of a single unit does not exceed 4 kg, ensuring ease of transport and installation.

ADVANTAGES OF THE "HAMMER 21-27" EW SYSTEM

The system provides omnidirectional jamming, creating interference in all directions and effectively neutralizing control signals regardless of UAV position. Multi-frequency operation allows simultaneous functioning across several bands, increasing the likelihood of successful communication suppression. The lightweight design of each unit ensures mobility and rapid deployment in field conditions. The "Hammer 21-27" is suitable for use at both stationary defense points and in mobile combat groups. The system easily integrates with other EW assets or surveillance systems, making it a versatile tool for the modern battlefield.
