This photo from a former Lockheed employee's office seems to have been taken at their Helendale RCS facility. I've seen it said that it was a prototype of the RQ-3 Darkstar, but it really doesn't look close enough to me. But I do think it is most likely simply an RCS target, and not any kind of actual craft.
I only have this photo from an article in Janes International Defense Review that seems to depict the same object or shape. The article seems to be in part about using massive computer arrays to process and simulate radar cross sections. I've only found an index on the article but don't know where I could get the whole thing to read. But it could indicate that this shape was important to them for some reason.
Is it possible Lockheed was trying to model the radar return of a disc shaped craft? Perhaps for their own use, or to more easily find targets in the field?
Does anyone know anything more about this?
