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.
