It’s most likely a scaled model otherwise it would make it smaller than most current drones the X-47B is pretty darn big it’s wingspan is larger than an F-18 h

The wingspan of the aircraft on that truck most definitely indicates a scaled model even if it uses a lifting body design. So as others have mentioned it’s probably a shape test not an actual aircraft design.
