General Atomics-Aeronautical Systems, Inc. (GA-ASI) began the first installation of factory upgrades to a Gray Eagle-Extended Range (GE-ER) Unmanned Aircraft System to enhance its capabilities to support Multi-Domain Operations (MDO). The MDO upgrade follows a series of demonstrations that showcased GE-ER’s persistent stand-off survivability with stand-in capabilities and up to 40 hours of endurance. Under the current program, the U.S. Army-funded program includes two aircraft. Flight tests and qualifications will start later this year.
