DZYNE Technologies has launched the Dronebuster Power Up Program, enabling users of earlier models, including Block 3, to upgrade to the latest Block 4 variant.
The upgraded Dronebuster Block 4 is designed to counter autonomous drone swarms by spoofing them and forcing each hostile drone backwards by up to 4 kilometers (2.5 miles).
Optimized for modern command-and-control (C2) and satellite navigation signals, the system features an optional Position, Navigation, and Timing (PNT) attack mode to disrupt even high-speed and frequency-agile drones.
It also delivers increased transmission power, wideband coverage, and can jam all major global navigation satellite systems, including GPS, Galileo, Glonass, and Beidou across different bands.

The Dronebuster Block 4 integrates with DZYNE’s Detection, Tracking, Identification system for coordinated counter-drone operations.
“It is a phenomenal capability that our competitors do not have,” Adam Wirth, Business Development Manager for DZYNE, wrote on social media. “Give your warfighters the best array of capabilities of any handheld system. Don’t leave them defenseless against autonomous UAVs (unmanned aerial vehicles).”
Additional Features
Weighing approximately 5.85 pounds (2.65 kilograms), the Block 4 uses a NATO-certified battery approved for both military and civilian transport. It also supports external direct current power to ensure continuous operation.
Battery life offers more than 60 minutes of active jamming and over 10 hours of detection time.
The weapon is also built to withstand harsh conditions, including dust, water, shock, and vibration, and includes RS-422 serial interfaces for easy integration with existing command-and-control systems.
According to the company, the Power Up Program provides a lower-cost alternative to replacing older systems while delivering the full capabilities of the Block 4.
