Gray Eagle MOSA-EW Upgrade for US Army
GA‑ASI will integrate MOSA‑EW into the Gray Eagle UAS to boost battlefield C5ISR and electronic‑warfare capabilities.
On October 13, 2025 General Atomics Aeronautical Systems, Inc. (GA‑ASI) announced the US Army awarded a contract to add Gray Eagle MOSA‑EW capability to its Gray Eagle unmanned aerial system (UAS). The move is framed as a step to strengthen C5ISR (Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance) and electronic warfare (EW) integration for future multi‑domain operations.
What the Gray Eagle MOSA-EW upgrade brings
MOSA‑EW stands for Modular Open Systems Approach—Electronic Warfare. GA‑ASI and the Army say the modular design will let operators swap or upgrade EW payloads faster, improving mission adaptability and interoperability with NATO allies. The announcement emphasizes software‑defined and open interfaces so new sensors and countermeasures can be integrated without long platform rework.
The Gray Eagle UAS, already used for intelligence, surveillance and reconnaissance missions, will retain its core airframe while gaining tighter EW and C5ISR links. GA‑ASI’s statement positions the upgrade as supporting coalition operations and multi‑domain coordination, where electronic‑spectrum effects must sync closely with ground and air components.
- Gray Eagle MOSA‑EW enables modular EW payloads and faster integration cycles.
- Enhances C5ISR connectivity for shared tactical data across platforms and allies.
- Focuses on interoperability standards to simplify future upgrades and coalition use.
The public announcement did not include contract value or delivery timelines. GA‑ASI and the US Army framed the effort as part of broader modernization to keep sensor and EW suites current as threats evolve. For analysts, the emphasis on MOSA points to a growing preference for open‑architecture upgrades that reduce lifecycle risk and speed capability insertion.
Expect follow‑up releases to detail specific payloads, testing milestones, and where integration and flight trials will occur; for now the October 13, 2025 award flags an important step toward networked, EW‑capable unmanned systems for allied operations.
