The U.S. assessment is supported by a photo taken last month by the commercial satellite company DigitalGlobe and provided to The Wall Street Journal. It shows a suspected jammer system with its antenna extended on Mischief Reef, one of seven Spratly outcrops where China has built fortified artificial islands since 2014, moving sand onto rocks and reefs and paving them over with concrete.
According to U.S. intelligence, the new cell phone jammer equipment was deployed within the past 90 days on Fiery Cross Reef and Mischief Reef.
The electronic jamming equipment would be consistent with a 2016 U.S. Department of Defense report that said China's People's Liberation Army views such electronic warfare as a "force multiplier" and "would likely employ it in support of all combat arms and services during a conflict."
China has installed equipment on two fortified outposts on the Spratly Islands capable of jamming communications and radar systems, which U.S. officials say signifies a stepped-up militarization of the South China Sea.
According to American defense officials, the Russian military is deploying a weaponized form of GPS gsm jammer that is effectively blocking some U.S. drone aircraft operations over Syria - and is even affecting drones equipped with anti-jamming technology. As more and more operators contemplate the deployment of autonomous vessels and aircraft in the maritime space, the vulnerability of high-specification military hardware to GPS jamming may pose a cautionary tale.
The U.S. Army wants drone-mounted signal jammers now to dominate future electronic warfare (EW) and is switching to a little-understood and lightly regulated contracting method to get them. NextGov reports.
Known as one of the most effective wifi jammer in the world, the Russian helicopter-based radio electronic warfare system Rychag-AV is capable of protecting the entire vehicle by "blinding" all enemy warplanes and missiles within several hundred kilometers.
The Rychag-AV is considered one of the world's most powerful jammers when it comes to disrupting the electronics of combat aircraft and cruise missiles. Russia's Rossiyskaya Gazeta daily cited military experts as saying that the Rychag-AV jammers added significantly to reducing the effectiveness of the US air strike on Syria's Ash Sha'irat airbase in April 2017.
The Next Generation Jammer Low Band program aims to develop a system that will work to build up the Growler’s electronic attack capabilities against incoming threats in the electromagnetic spectrum’s lower frequency bands
