At DEFEA 2023, a defense exhibition in Athens, Greece, the Polish company AREX WB Group in partnership with Prexer introduces the DJ-25 jammer kit mounted on a ZSU-23-2 anti-aircraft twin-barrelled automatic gun. The jammer kit is designed to disrupt and disable enemy communications and guidance systems, effectively rendering their weapons useless. DJ-25 jammer kit is added to the anti-aircraft gun as a self-protection weapon system and also an anti-drone weapon as well.

The ZSU-23-2 is a Soviet-era anti-aircraft gun that has been in use for decades. It has proven to be a reliable and effective weapon system, but as technology has advanced, so too have the tactics of enemy forces. In order to stay ahead of the curve, the development of the jammer kit was necessary. Two Polish companies – Arex (WB Group) and Prexer – are proposing a solution.
The kit consists of a series of electronic jammers that can be mounted onto the ZSU-23-2 gun. The jammers emit high-powered signals that disrupt enemy communications and guidance systems, causing their missiles and other weapons to malfunction or miss their targets.
According to military officials, the jammer kit has undergone extensive testing and has been proven to be effective in a variety of scenarios. It has already been deployed in several conflict zones with great success and is expected to become a standard feature of ZSU-23-2 gun systems in the near future.
The ZU-23-2 anti-aircraft twin-barreled automatic cannon has long been a reliable and powerful weapon in countering airborne threats. To further enhance its capabilities, a specialized jammer kit called the DJ-25 has been developed. This kit is designed to disrupt the communication and navigation systems of unmanned aerial vehicles (UAVs), making the ZU-23-2 even more effective in taking down these threats.
The DJ-25 Jammer Kit boasts a range of up to 2,500 meters, depending on the type of UAV being targeted. Its output power can vary between 25 and 50 watts, depending on the specific jamming band in use. This allows it to effectively jam 2.4GHz and 5.8GHz frequencies, as well as geolocation systems such as GPS, Galileo, GLONASS, and GSM in the 850-900MHz range.
Designed for use in a variety of environments, the DJ-25 has an operating temperature range of -20°C to +60°C. The angle of the jamming beam can be adjusted to 10°, depending on the frequency being utilized. This allows for more precise targeting of UAVs and the disruption of their communication systems.
The DJ-25's amplifiers weigh in at 7 kg, while the antenna's weight varies between 5 and 8 kg, depending on the specific configuration. This lightweight design makes the jammer kit easy to integrate with the ZU-23-2 anti-aircraft cannon. Power consumption for the DJ-25 is configurable, with a maximum of up to 350 watts. The jammer kit is powered by a 24 V DC supply voltage, making it compatible with many existing power sources.
In summary, the DJ-25 Jammer Kit is a powerful addition to the ZU-23-2 anti-aircraft twin-barreled automatic cannon. By disrupting the communication and navigation systems of UAVs, the DJ-25 enhances the effectiveness of the ZU-23-2, making it an even more formidable weapon in the fight against airborne threats.
