DARPA and Northrop Grumman launch XRQ-73 Shepard hybrid-electric ISR demonstrator at Edwards
DARPA and Northrop Grumman have completed the first flight of the XRQ-73 Shepard, an uncrewed reconnaissance platform designed to demonstrate hybrid-electric propulsion for future autonomous systems. Built with Scaled Composites, the “flying wing” uses electricity generated by a gas turbine to drive an ultra-quiet propulsion system. Flight tests are underway at Edwards Air Force Base.
