Sierra Nevada Corp has been awarded a $205 million US Special Operations Command contract
to supply support services for Special Operation Command's Dismounted Counter Radio-Controlled Improvised Explosive Device Electronic Warfare systems. Work will run through Sept. 12, 2022, and performed in Sparks, Nev., and Folsom, Calif. The Dismounted Counter Radio-Controlled Improvised Explosive Device Electronic Warfare system is part of the wider Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) series of IED jammers. The JCREW
is designed to jam enemy radio-frequencies used to detonate improvised explosive devices. It comes in three different models, including a man-portable version for foot patrols, vehicle-mounted variants, and a static model for protecting key points at installations.
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.
