Deployment roles for Defender reactive jamming systems

Defender systems are configured per project for the role they serve. Frequency ranges, power allocation, and jamming mode are defined in software, so one platform covers multiple roles without hardware changes. The roles below are the deployments Defender systems are supplied for, each delivered on the Modular or Manpack platform.

Counter-UAS & counter-drone

Engaging FPV and frequency-hopping drone links

FPV and commercial drones use control and video links that hop across frequencies many times per second. A jammer that transmits continuously must cover the whole band at once, dividing its power across frequencies the drone is not using.

Defender responds to each detected transmission instead of broadcasting continuously. Every frequency hop triggers a new detection-and-response cycle in FPGA hardware, tracking up to 55,000 hops/s and responding from 18 µs, so jamming follows the control link across hops. Power is concentrated on the active frequency, which extends effective range and leaves other spectrum clear.

Defender engages drone control and video links, and can run different modes across different frequency ranges at once — for example reactive jamming on a hopping control link while a fixed denial band covers the video downlink. The capability is delivered on the man-portable Defender Manpack and the scalable Defender Modular platforms, and the underlying method is described in how reactive jamming works. Deployments include dismounted counter-UAS, vehicle-mounted and convoy overwatch, and fixed-site coverage.

Telecom & cellular denial

Denial of cellular and 5G links within a defined area

Defender provides targeted denial of cellular and 5G links within a defined operational area. Because allocation is software-defined, one unit covers the range from narrowband single-band targeting — such as 5G denial — to wideband multi-service coverage across 20-8000 MHz. Denial runs continuously where required, or reactively to reduce the system's own emissions when no target is present.

Convoy and force protection

Mobile and dismounted RF coverage

On the man-portable Defender Manpack, Defender provides coverage for dismounted patrols, checkpoints and VIP protection. On Defender Modular and vehicle-mounted configurations, the same capability scales for convoy overwatch and mobile deployment, with frequency coverage and power allocated per mission.

Facility & critical-infrastructure protection

Fixed-site and wide-area defence

Airfields, military bases, critical infrastructure and government sites require persistent, wide-area coverage. The Defender Modular series is built for this role: modules deploy distributed across a site for wide-area coverage, or co-located to concentrate power on a defended approach, operating as one synchronised system through Leo control software. Coverage and frequency allocation are defined per site. Defender integrates with existing detection through REST API or the NATO SAPIENT protocol, acting as the defeat layer alongside third-party radar, EO/IR and RF sensors.
