Airborne Early Warning Integration for Uncrewed Aircraft

General Atomics Aeronautical Systems, Inc. (GA-ASI) and Saab have completed the first validation flight of an MQ-9B remotely piloted aircraft equipped with airborne early warning (AEW) radar pods. The cooperation focuses on extending persistent airborne surveillance capabilities for defense and security operations using medium-altitude, long-endurance uncrewed aircraft systems.

The development targets applications including early threat detection, long-range air surveillance, target tracking, and integrated airspace monitoring. The system is intended for use in operational environments requiring continuous situational awareness over extended areas through digital infrastructure and SATCOM-enabled connectivity.

Cooperation Structure and Technical Roles
Under the partnership, GA-ASI is responsible for integrating the AEW capability into the MQ-9B aircraft platform, including flight testing, system validation, and operational deployment. Saab provides the AEW sensor technology, designated LoyalEye, including radar and surveillance functionality.

The MQ-9B platform serves as the airborne carrier for the radar pods and communication systems. Saab’s radar payload is designed to provide airborne detection and tracking of tactical aircraft, guided munitions, drones, and other airborne threats. Integration activities include sensor interfacing, power management, communication architecture, and flight performance validation.

The validation flight was conducted on 19 May at GA-ASI’s Desert Horizon flight operations facility in Southern California using a company-owned MQ-9B aircraft. The test marked the initial phase of a development program expected to continue over several months before a full operational demonstration.

System Architecture and Operational Functions
The integrated AEW system combines radar surveillance capability with the endurance profile of the MQ-9B platform. The aircraft supports beyond-line-of-sight operations through SATCOM connectivity, enabling remote transmission of surveillance and tracking data.

The solution is intended to support persistent monitoring missions in areas where conventional airborne early warning aircraft may be unavailable or operationally limited. MQ-9B configurations involved in the development include SkyGuardian, SeaGuardian, the United Kingdom’s Protector variant, and the MQ-9B STOL configuration under development for carrier-based operations.

The cooperation addresses operational requirements for continuous airborne surveillance with reduced crew exposure during missions. By combining unmanned aircraft endurance with AEW radar capability, the partners aim to extend detection coverage and operational flexibility for defense operators.

“AEW for MQ-9B will offer critical aloft sensing to defend against tactical air munitions, guided missiles, drones, fighter and bomber aircraft, and other threats,” said David R. Alexander, President of GA-ASI.

“This partnership integrates MQ-9B with LoyalEye, equipping operators with vital information for critical decision-making,” said Carl-Johan Bergholm, Senior Vice President and Head of Business Area Surveillance at Saab.
