The harm of a jammer to a country is very large von perfectjammers Blog

A thorough cyber assessment of navigation bridges may show that GPS signal loss, gps jammer or spoofing could result in some or all of the other navigational units being affected including gyrocompasses, steering systems, radar/ARPAs, echo sounders, DSC VHF radios, etc. Mitigations might include having manufacturers provide signal strength alarms on new GPS receivers, employment of inertial navigation systems, RF jamming detectors and alternate positioning systems like enhanced Loran (eLoran). The eLoran positioning system is already well-proven, highly jam-resistant, accurate as GPS and fills GNSS voids in areas like urban canyons, inside dense structures and tunnels, underground and underwater. A robust terrestrial system like eLoran is not susceptible to extreme space weather (ESW) like satellite systems.

Russia's Rossiyskaya Gazeta daily cited military experts as saying that the Rychag-AV portable jammer added significantly to reducing the effectiveness of the US air strike on Syria's Ash Sha'irat airbase in April 2017.The NGJ will replace the ALQ-99 tactical jamming system on the Navy’s EA-18G Growler electronic warfare aircraft beginning in 2020. In July, the Naval Air Systems Command awarded Raytheon a $279.4 million contract for the NGJ technology development phase. Northrop Grumman and BAE Systems also competed for the program; the latter has protested the contract award to the GAO.

Billed as the only operational tactical drone jammer fighter in the world, the Growler is a specialised version of the F/A18-F Super Hornet, and since achieving initial operational capability in September 2009, it has been equipped with the AN/ALQ-99 airborne EW system. The AN/ALQ-99 itself, however, can claim much older ancestry, having been designed in the late 1960s, and first fielded in 1971with the introduction of the EA-6 Prowler, the EW variant of the A-6 Intruder, in time to see combat service in Vietnam.

A signal jammer is a kind of device which blocks reception or transmission of signals, typically by forming some kind of interference at that same frequency range that cell phone normally use. Due to that, a cell phone user will either lose the signal or experience significant loss of the signal quality. Signal jammers have both malicious and benign uses. Military and the police often use them for the purpose of limiting or disrupting communications during the hostage situation, during bomb threats or when the military action is ongoing.. The growth of signal 4G jammer market is highly reliant on the growth of application of signal jammers in military and defense industry globally.

In the future, while we will hopefully never fight Russia or China, we almost certainly will fight someone who has bought advanced jamming and electronic warfare systems from them or even some of our own allies, said Tom Greco, Gen. Perkins’ chief of intelligence: “It is not a stretch to say that just about any capability that we have has the potential of being disrupted.”
