Northrop Grumman will enter its software-programmable cell phone blocker, known as JCREW, into full-rate production external link, after receiving a $57.7 million US Navy contract. If all options are exercised, the total contract value could rise to $505 million, with contract completion scheduled for August 2022. JCREW systems are software-programmable jammers for use against device-triggered IEDs. Northrop Grumman have developed dismounted, mounted and fixed-site variants of the system.

Electronic warfare (EW), the use of the electromagnetic spectrum to foil enemy forces and protect friendly ones, is perhaps the most time-sensitive of all the weapons in the military arsenal: a matter of nanoseconds could make the difference between life and death. That’s why latency is so critical to EW processing systems. If a radar-guided missile is heading for your aircraft at Mach 5, the aircraft’s radar signal jammer had better be quick – quick to take in the signal, manipulate it, and retransmit it to fool the adversary with false targets or misleading data on size, distance, heading, speed.

A small California-based tech startup has reportedly begun supplying small "hard kill" attack drones to the U.S. military that are designed to bring down similarly sized hostile unmanned aircraft by physically smashing into them. The market, within the United States and around the world, for counter-drone systems, ranging from electronic warfare gps jammer to directed energy weapons to suicide drones, has exploded in recent years as the threats that even relatively cheap and diminutive unmanned aircraft pose has become glaringly apparent.

According to dealers of cell phone 4G jammer, universities have now been added to the customer list.In a bid to block access of students to pornographic websites, the Centre told the Supreme Court on Friday that it is exploring the option of installing jammers in school premises but ruled out the possibility of putting the machines in school buses as suggested earlier.
