Experimental Vehicle Takes To Skies In X-Prime Program
Northrop Grumman has successfully flown DARPA’s hybrid-electric Shepard vehicle as part of the X-Prime program, which aims to bridge the gap between technology demonstration and full-scale development. The program, initiated by DARPA in 2021, seeks to transition capabilities from research to operation. The Shepard vehicle’s flight marks a significant milestone in the development of hybrid-electric propulsion technology. This development was first reported by Aviation Week.
