HII Debuts GRIMM Spectrum Dominance Solution at AOC 2025 International Symposium & Convention

McLEAN, Va., Dec. 08, 2025 (GLOBE NEWSWIRE) — HII (NYSE: HII) announced today that its Mission Technologies division has deployed and operationalized a next-generation high-performance spectrum dominance solution, now available for rapid detection and location of hostile communications, radar and other electronic threats.

HII will showcase its GRIMM® technology — and its field-proven capabilities in situational awareness, intelligence support and force protection — at the Association of Old Crows’ 2025 International Symposium & Convention at National Harbor, Maryland.

GRIMM® leverages decades of HII expertise developing electromagnetic warfare technology for national defense. Now deployed with mission success across a range of defense customers, it stands as a testament to HII’s commitment to innovation and operational excellence.

“GRIMM® is a proven strategic asset for the U.S. military and its allies — and it is available now,” said Andy Green, executive vice president of HII and president of Mission Technologies. “Mission success requires a multi-domain, fully capable solution that provides the agility and precision our forces need to protect national interests worldwide, and GRIMM is delivering that capability today.”

GRIMM can fulfill a variety of missions, including military operations; counterterrorism and counternarcotics; intelligence, surveillance and reconnaissance; border security; and electromagnetic warfare (EW) and RF-enabled cyberspace operations. To date, the system has been deployed on unmanned platforms for both passive and active EW missions.
