A YouTube video posted by the account Uncanny Expeditions appears to show a previously unseen object undergoing testing at Lockheed Martin’s Helendale Radar Cross Section (RCS) Test Range in California’s Mojave Desert.
The object, seen mounted on a pylon or support attached to a flatbed truck, appears in several sequences showing different angles and lighting conditions.
