The U.S. Air Force has begun a market survey to purchase more Dronebuster 4 handheld counter-drone systems from DZYNE Technologies. The announcement, published on March 19, 2026, came from the 20th Contracting Squadron at Shaw Air Force Base in South Carolina. Vendors must submit their responses by March 26.
The survey aims to find suppliers who can deliver three Dronebuster 4 units and provide timelines for fulfillment. If the process moves forward after the survey, procurement will use a firm-fixed-price contract structure.
What the Dronebuster 4 Does
The Dronebuster 4 is a small, portable electronic warfare device designed to detect and disrupt commercial drones at short distances. It combines Position Navigation Timing (PNT) attack and spoofing features, allowing operators to interfere with both drone control links and navigation systems. Importantly, the system aims to combat “dark drones,” which are autonomous platforms that function without any active radio control signals.
Key Specifications
The device measures 21.6 × 10.9 × 4.5 inches and weighs roughly 5.10 pounds without a battery, rising to 5.85 pounds with its NATO mil-spec battery. It delivers over 60 minutes of active jamming on battery power and more than 10 hours of detection when connected to an external power source.
The system supports both handheld and fixed-site configurations through side-mounted attachment points and RS-422 serial interface connectivity, allowing integration into broader command-and-control networks. It is rated to IP65 and tested to MIL-STD-810 standards, making it suitable for adverse field conditions.
Operational Purpose
The Dronebuster 4 provides personnel with a quick response tool against small drone threats. It does not depend on larger, vehicle-mounted systems. By disrupting control or navigation signals, it can make a drone land, return to its starting point, or completely lose mission capability.
The system is already authorized for use within the U.S. Department of Defense structures. Its development addresses a growing operational gap, as small commercial drones are increasingly used for reconnaissance and surveillance at low altitudes where traditional air defense systems are less effective.
