OVERVIEW: The Counter-UAV (C-UAV) Jammer Gun is a man-portable electronic warfare device designed to disrupt the control, navigation, and data links of hostile drones using targeted radio frequency jamming.

DETAILS: Resembling a rifle in form factor, the C-UAV Jammer Gun projects directed RF energy toward an airborne drone, effectively severing its command link (C2), navigation (GNSS/GPS), or both. It operates across multiple frequency bands commonly used by commercial and tactical UAVs. Once disrupted, the drone may hover, return to home, or crash, depending on its fail-safe programming. The system typically includes directional antennas and internal power sources, allowing single-operator use without auxiliary equipment. It is employed in urban, tactical, and perimeter defense roles.

ROLE SUMMARY:
Category: Directed-Energy Electronic Warfare Weapon
Primary Use: Drone disruption and denial
Function: RF jamming of control and navigation signals
Strong Against: Commercial and tactical UAVs relying on RF/GNSS links
Weak Against: Autonomous drones, frequency-agile or hardened UAVs
Platform: Man-portable (shoulder-fired form factor)
Integration: Standalone use or networked with larger C-UAS systems
