Jammer is a lightweight, soft killer

Moscow’s utilization of electronic warfware (EW) in Ukraine and other countries, combined with the use of cutting edge Russian air defences – possible one of the best on the planet – has returned jamming in the interest point for the US Navy and its armada of EA-18G Growlers.The Raytheon Company, manufacturer of the low-cost flight vehicle, spent the last two years upgrading the jammer version of the platform, known as MALD-J, to include electronic warfare capabilities, as part of the $34.8 million MALD-X demonstration effort

While the tasks of the aforementioned helicopters are relatively straightforward, the SyAAF also operates at least two Mi-17s airborne jamming platforms for the jamming of enemy air defence radars. First seen during a large-scale Syrian Arab Air Force exercise in July 2012, the first type was seen equipped with two oddly shaped containers installed on either side of the fuselage. While the exact purpose of these containers remain unknown, it is now believed that they are part of the North Korean TACAN electronic jamming system installed onboard at least one SyAAF Mi-17.

Consequently, the newly-released drone gun jammer is a lightweight “soft kill” counter-drone jammer which is designed for use on remote weapon stations (unmanned gun systems) as part of a combined “hard kill/soft kill” layered system. It is system-agnostic and can be integrated with any third party remote weapon station, thus allowing manufacturers of unmanned weapons systems to add a “soft kill” option to their existing products, which may already be in service.

The drone was likely targeted with a cell phone signal jammer, which simply consists of a device equipped with a radio transmitter that can output multi-band frequencies. The drone's receivers are then saturated, and it can no longer interpret instructions from the person flying it. The UAV fell into the sea, and according to Fstoppers, the city of Toulon has opened an investigation into the matter and has divers searching for the wreckage to further study it.

The drone gun jammer is a lightweight, soft kill, drone jamming solution for use on remote weapon stations. The drone gun jammer module will force drones (single or swarm attack) into a fail-safe mode where they will either hover or slowly descend. This function will allow the operator to utilize a kinetic weapon or other mounted equipment to more easily neutralize the target. Included Perfectjammer jamming technology has been developed specifically for drone mitigation, offering an effective response to an urgent threat.
