Increasing the flight time of unmanned aerial vehicles (UAVs) has been an important task for many manufacturers, as it enables the UAV to operate a wider range of missions.

Lockheed Martin engineers have recently updated the engine on the Fury UAV to increase its flight endurance. Fury is a long-endurance, expeditionary aircraft that leverages its advanced fuel propulsion system, power generation and low signature design to deliver capabilities to Class 3 UAV. It has no landing gear, making it a runway-independent UAV, according to

With the integration of the 1803 engine into the platform, engineering tests performed by the company indicate that Fury will be able to stay in the air for 15 continuous hours.

“We’ve engineered Fury to bring the flight endurance and other advantages of much larger unmanned aircraft into a compact, effective, category three system,” says Kevin Westfall, director of Unmanned Systems at Lockheed Martin.
