The Gray Eagle® STOL (Short Takeoff and Landing) is an advanced unmanned aircraft system (UAS) developed by General Atomics Aeronautical Systems (GA-ASI). It builds upon the capabilities of the proven Gray Eagle UAS, integrating STOL-optimized aerodynamics and propulsion that allow it to operate from a wide range of airstrips, including warships, dirt fields, and semi-improved runways.
Gray Eagle STOL incorporates open architecture, autonomy, and machine learning to enhance battlefield awareness and adaptability. Its ability to take off from short runways while carrying a significant payload, including up to 16 Hellfire missiles, makes it a formidable asset for attack, reconnaissance, and contested logistics missions.
Gray Eagle STOL features modernized avionics and data links, sharing command and control systems with the Gray Eagle 25M, ensuring seamless interoperability. Additionally, its weatherized airframe increases reliability in extreme conditions, making it a versatile asset for expeditionary forces.
Mission Capabilities
Gray Eagle STOL can be configured for various operations, including:
- Armed Reconnaissance
- Contested Logistics
- Advanced Teaming With Air-Launched Effects (ALE)
- Signals Intelligence (SIGINT) & Electronic Warfare (EW)
- Long-Range Strategic ISR
