Us electronic jamming strategy

Electronic GPS signal jammer plays a powerful role in war

The U.S. strategy was defined in six words: “Put them back on the wire.” By neutralizing radio-controlled bombs, the jammers would force insurgent bombmakers to use more rudimentary triggers, such as command wire. Those triggers would be simpler to detect, in theory, and would bring the triggermen closer to their bombs, where U.S. troops could capture or kill them.

The jammer generally causes a drone to either perform a vertical controlled landing or return to its starting point – the default actions of most drones that lose communication

As more jammers flooded the war zone, the mess grew messier. For many months, the shortcomings in electronic warfare expertise had been evident among Army and Marine units. “We had all these boxes over there and people didn’t know how to use them,” said Rear Adm. Arch Macy, commander of the Naval Surface Warfare Center. “They’d turn them on, thinking they were protected when they weren’t.”

Electronic “fratricide” intensified, with more instances of wifi jammer disrupting coalition radios and even the radio links to unmanned aerial vehicles. More troops switched off their CREW systems rather than risk disrupting their radios; rumors circulated that jammers actually detonated IEDs.

The US Navy owns the only operational tactical jamming fighters in the world, but the AN/ALQ-99 pods they depend on use analog technologies, are hard to maintain, and have reliability issues. All-digital technologies and modern transmit/receive electronics offer huge leaps ahead in capability and availability, which is why the US military is working on a Next-Generation Jammer (NGJ) replacement for the pods on its tactical strike aircraft.

The current jamming system used in the Fleet is the AN/ALQ-99 Tactical Jamming System (TJS), which Northrop Grumman has modernized to the ICAP III standard. The overall system was designed in the late 1960s, and fielded with the introduction of the EA-6 Prowler in 1971.
