Northrop Grumman won a $245 million contract modification from the Naval Sea Systems Command to support the Expeditionary Warfare Program Office. The modification provides for the Joint Counter-Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW)
Increment 1 Block 1 (I1B1) systems full-rate production. JCREW devices are high-power, modular, programmable, multiband radio frequency jammers designed to deny enemy use of selected portions of the radio frequency spectrum. Northrop Grumman was selected to work on the JCREW 3.3 program, which has been replaced by the JCREW I1B1 development, but the terms can be used synonymously. According to the Department of Defense
, the JCREW I1B1 system is the first-generation system that develops a common open architecture across all three capabilities and provides protection for worldwide military operations. This integrated design maximizes commonality across all capabilities, reduces life cycle costs and provides increased protection against worldwide threats. Work will take place in San Diego, California and is scheduled to be finished by January 2021.
The US military is working on the next-generation of jammers to defeat improvised explosive devices (IEDs) that pose such a grave threat to US forces deployed overseas. The jammers are called Joint Counter Radio-Controlled Improvised Explosive Device (RCIED) Electronic Warfare (JCREW) devices. They are high-power, modular, programmable, multiband radio frequency jammers designed to deny enemy use of selected portions of the radio frequency spectrum. They come in 3 varieties – fixed, mounted, and dismounted.
The first generations of JCREW devices were developed and deployed quickly to meet an urgent need in the field. The next generation of JCREW devices, known as 3.x, are being developed to increase capabilities and tap into the power of the network to enhance their effectiveness. The JCREW 3.1 version is a dismounted device, the 3.2 version is a mounted device, and the 3.3 version is being developed to work in mounted, dismounted, and fixed-installation roles, using a common open architecture of electronics.
