- U.S. Air Force launched a market survey to identify suppliers capable of providing Dronebuster 4 handheld counter-drone systems developed by DZYNE Technologies
- The requirement outlines three portable electronic warfare devices designed to detect and disrupt small unmanned aerial systems at short range
The United States Air Force looks to buy additional Dronebuster 4 handheld counter-drone systems developed by DZYNE Technologies, launching a market survey through the 20th Contracting Squadron at Shaw Air Force Base, South Carolina. The notice, published on March 19, 2026, calls on industry to confirm its ability to supply the systems, with responses due by March 26.
According to the notice, the Air Force is seeking vendors capable of delivering Dronebuster 4 systems and providing timelines for fulfillment following a purchase order. The procurement is expected to follow a firm-fixed-price structure if it proceeds beyond the current market survey stage.
Supporting documentation indicates a requirement for three Dronebuster 4 units. The system is described as a compact, man-portable electronic warfare device designed for detection and disruption of commercial drones, particularly in short-range, line-of-sight scenarios.
The Dronebuster 4 integrates Position Navigation Timing (PNT) attack capabilities and spoofing functions, allowing operators to interfere not only with drone control links but also with navigation systems used by waypoint-guided or autonomous platforms. The system is specifically intended to counter “dark drones,” which operate without active radio control signals.
From a physical standpoint, the device measures 21.6 inches in length, 10.9 inches in height, and 4.5 inches in width. It weighs approximately 5.10 pounds without battery and 5.85 pounds when equipped with its NATO mil-spec battery, making it suitable for extended dismounted use by security forces and rapid response teams.
The system provides more than 60 minutes of active jamming capability on battery power and can sustain over 10 hours of detection when connected to external power sources. This dual-mode endurance supports both mobile operations and semi-fixed deployments at checkpoints or perimeter positions.
In addition to its handheld configuration, the Dronebuster 4 includes RS-422 serial interface connectivity, allowing integration into broader command-and-control architectures. It also features mounting points on both sides, enabling installation in fixed-site configurations where continuous coverage is required.
The system operates using directional emissions for navigation-frequency jamming, a design choice intended to reduce unintended interference with friendly systems. It is rated to IP65 standards and tested to MIL-STD-810 environmental requirements, indicating suitability for use in adverse weather and field conditions.
The requirement document also notes that the Dronebuster is authorized for use within the U.S. Department of War, indicating that the system is already approved for operational employment within U.S. military structures.
The Dronebuster 4 is designed to give personnel an immediate response tool against small drone threats without reliance on larger vehicle-mounted systems. By disrupting control links or navigation signals, the system can force a drone to land, return to its origin, or lose mission capability.
This type of handheld electronic attack system addresses a growing operational gap. Small commercial drones are increasingly used for reconnaissance, surveillance, and probing of base defenses, often at low altitude and short range where traditional air defense systems are less effective.
