DARPA/AFRL and Northrop Grumman start flight testing XRQ-73 SHEPARD hybrid-electric flying-wing drone at Edwards
Northrop Grumman and Scaled Composites launched flight testing of the XRQ-73 SHEPARD hybrid-electric, uncrewed flying-wing prototype at Edwards Air Force Base. DARPA says the April 2026 flights demonstrate series hybrid-electric propulsion aimed at enabling very quiet, high-efficiency performance for next-generation lightweight autonomous systems.
