How Saab & General Atomics Are Enhancing MQ-9B with UAEW Capabilities

-

Saab and General Atomics Aeronautical Systems have announced the development of an Unmanned Airborne Early Warning UAEW solution, leveraging the advanced capabilities of the MQ-9B unmanned aerial system. This partnership marks a significant step forward in airborne surveillance technology, offering persistent monitoring and enhanced situational awareness for military and defense applications.

MQ-9B

Traditional Airborne Early Warning & Control (AEW&C) systems have relied on manned aircraft, such as Saab’s GlobalEye, to provide long-range detection and tracking of airborne threats. However, the integration of Saab’s AEW sensors with General Atomics’ MQ-9B platform introduces a new era of unmanned surveillance, capable of operating autonomously or in conjunction with manned aircraft.

This medium-altitude AEW solution is designed to complement existing AEW&C fleets while expanding operational flexibility. The MQ-9B’s long-endurance capabilities allow for continuous monitoring of designated areas, making it an ideal choice for persistent surveillance missions.

Saab and General Atomics plan to begin flight testing of the AEW-equipped MQ-9B in 2026. This initiative reflects the growing demand for unmanned systems capable of long-endurance surveillance, particularly in environments where persistent monitoring is required and manned operations may be constrained by risk or limited resources.

Advantages of the UAEW System

1. Persistent Surveillance

One of the biggest advantages of an unmanned AEW system is its ability to provide continuous monitoring over a designated area. Unlike manned aircraft, which require crew rotations and refueling stops, the MQ-9B UAV can operate for extended periods, ensuring uninterrupted intelligence gathering.

2. Cost Efficiency

Traditional AEW&C aircraft, such as the E-3 Sentry or Saab GlobalEye, require high operational costs, including fuel, maintenance, and crew salaries. The MQ-9B-based UAEW system offers a more affordable alternative, reducing expenses while maintaining high-end surveillance capabilities.

3. Reduced Risk to Personnel

Since the UAEW system is unmanned, it eliminates the risk to pilots and crew members in high-threat environments. This is particularly beneficial in combat zones, where manned aircraft could be vulnerable to surface-to-air missiles or enemy fighters.

4. Manned-Unmanned Teaming

The UAEW system can function independently or in coordination with manned AEW&C platforms, enhancing operational flexibility. This allows military forces to optimize their surveillance strategies, using unmanned assets for prolonged missions while deploying manned aircraft for complex operations.

5. Enhanced Threat Detection

Equipped with Saab’s AEW sensors, the MQ-9B can detect tactical aircraft, guided missiles, and drone swarms at long range. This capability strengthens air defense strategies, providing early warning against potential threats.

Disadvantages of the UAEW System

1. Vulnerability to Electronic Warfare

Unmanned systems rely heavily on satellite communication and data links. This makes them susceptible to electronic warfare tactics, such as jamming or cyberattacks, which could disrupt operations or even compromise control of the UAV.

2. Limited Defensive Capabilities

Unlike manned AEW&C aircraft, which can be escorted by fighter jets, the MQ-9B UAV lacks self-defense mechanisms. If detected by enemy forces, it could be targeted and destroyed, reducing its effectiveness in high-threat environments.

3. Dependence on Ground Control

The UAEW system requires ground-based operators to manage its missions. While automation plays a significant role, human oversight is still necessary for decision-making and real-time adjustments. This dependency could pose challenges in situations where communication is disrupted.

4. Weather Sensitivity

Unmanned aerial systems, including the MQ-9B, may be more affected by extreme weather conditions compared to larger, manned aircraft. Strong winds, storms, or icing could impact flight stability and sensor performance, limiting operational effectiveness.

5. Ethical and Legal Considerations

The increasing use of unmanned surveillance systems raises ethical and legal concerns, particularly regarding privacy, airspace regulations, and autonomous decision-making. Military forces must navigate these challenges to ensure responsible deployment of UAEW technology.

The Unmanned Airborne Early Warning (UAEW) system represents a major advancement in airborne surveillance, offering persistent monitoring, cost efficiency, and reduced risk to personnel. However, it also comes with challenges, including electronic warfare vulnerabilities, limited defensive capabilities, and operational dependencies. As Saab and General Atomics continue to refine this technology, the UAEW system is expected to play a critical role in modern defense strategies, providing enhanced situational awareness and threat detection for military forces worldwide.

The integration of Saab’s Airborne Early Warning (AEW) sensors onto the MQ-9B unmanned aerial system raises important considerations about power requirements and energy efficiency.

Powering the AEW System on MQ-9B

The MQ-9B is designed as a medium-altitude, long-endurance unmanned aerial vehicle (UAV), meaning it has limited onboard electrical power compared to larger, manned AEW&C aircraft. However, General Atomics and Saab have specifically engineered this system to ensure that the AEW sensors can operate efficiently within the UAV’s available power capacity.

Energy Efficiency and System Optimization

To make this possible, Saab’s AEW sensors have been optimized for lower power consumption, ensuring they can function effectively without overwhelming the MQ-9B’s electrical systems. The UAV’s onboard power generation is sufficient to support radar operations, communication systems, and data processing, allowing it to perform early detection, long-range tracking, and simultaneous target engagement.

Challenges and Limitations

While the MQ-9B can support AEW operations, there are some limitations:

  • Power Constraints: The UAV’s electrical capacity is lower than traditional AEW&C aircraft, meaning it may not support high-power radar systems used in larger platforms.

  • Operational Trade-offs: To ensure optimal energy usage, the AEW system may need to prioritize certain functions, such as focusing on specific threat detection rather than full-spectrum surveillance.

  • Mission Duration: While the MQ-9B has long endurance, continuous AEW operations may require energy management strategies to prevent excessive power drain.

Future Enhancements

General Atomics and Saab are working on further optimizing the AEW system for the MQ-9B, including advanced power management solutions and potential upgrades to onboard energy generation. These improvements could enhance the UAV’s ability to support more powerful radar systems while maintaining long-endurance surveillance capabilities.

The MQ-9B’s electrical energy is sufficient to operate Saab’s AEW sensors, but with certain limitations. The system has been engineered for efficiency, ensuring that it can provide valuable airborne early warning capabilities while maintaining long-endurance operations. However, power constraints may limit the scope and intensity of AEW functions compared to larger, manned platforms.
