HII has unveiled its new GRIMM electronic warfare system, a compact tool weighing just one kilogram, which enhances threat detection and tracking capabilities in contested electromagnetic environments. Operating across a frequency range of 10 megahertz to 18 gigahertz, GRIMM supports diverse missions, including intelligence, surveillance, reconnaissance, and counterterrorism, while maintaining operator anonymity. Its flexibility allows deployment on various platforms such as high-altitude balloons and unmanned systems, providing real-time actionable data for enhanced situational awareness. This innovation is significant for the defense sector, particularly in border security and law enforcement, as it empowers agencies to address complex threats effectively.
