DARPA has made a decision not to proceed to Phase 3 of the Aurora Flight Sciences’ XV-24A LightingStrike hybrid-electric, high-speed vertical-takeoff-and-landing (VTOL) X-plane, Aviation Week reports.
The research agency cites the lack of a service partner and commercial interest as reasons for the termination.
Aviation Week added that there were issues developing the 1-megawatt generator need for the aircraft as well.
