GRIMM is an EW system, weighing under two pounds, operating across 10 megahertz to 18 gigahertz, providing real-time signal detection, geolocation, and tracking.
HII’s New GRIMM system brings a sharp edge to the electronic warfare (EW) fight, spotting and tracking threats the moment they appear.

It delivers continuous monitoring with optional transmit function, supporting force protection as well as intelligence, surveillance, and reconnaissance missions.
