US Army Taps GA-ASI To Add MOSA-EW Capability Onto Gray Eagle UAS
SAN DIEGO – 13 October 2025 – The U.S. Army has awarded General Atomics Aeronautical Systems, Inc. (GA-ASI) a new contract to add a C5ISR Modular Open Suite of Standards (CMOSS)-compliant open architecture Electronic Warfare (EW) capability onto the MQ-1C Gray Eagle® Unmanned Aircraft System (UAS).
This will be the third EW capability that has been integrated into the CMOSS chassis, showing how quickly and easily new plug-and-play capabilities can be integrated into the Gray Eagle platform. Other recent additions include Electronic Attack, Communications Relay, Counter-UAS, and Signals Intelligence.
Gray Eagle’s Modular Open Systems Architecture (MOSA) streamlines the integration of the new EW capability, which leverages previous operational demonstrations and exercises applicable to Gray Eagle Extended Range and Gray Eagle Short Takeoff and Landing (STOL) variants. This capability signals a major step forward in the ability to conduct deep sensing in the Pacific while increasing the survivability and lethality of the Gray Eagle at distances relevant in the INDOPACOM Area of Responsibility.
“Persistent, long-endurance, long-range UAS combined with EW means that the U.S. Army division commanders can apply the powerful EW effects of the Gray Eagle to neutralize threats to the maneuver force at a time and location of their choosing,” said GA-ASI President David R. Alexander.
GA-ASI will collaborate with AeroVironment, Inc. (“AV”) (NASDAQ: AVAV) to integrate the company's SharkCage Expeditionary C5ISR Chassis (ECCv3) onto the platform. Since 2024, GA-ASI and AV have jointly demonstrated a range of capabilities on the Gray Eagle open architecture chassis.
