Compared with KJ-200, KJ-500 has an embedded box on top of head radome (which makes it tilted downward). That box must house the auxiliary antenna for the calibration of top phased arrays, similar to that on a 052D destroyer.

So you think the small protrusion on top of the radome (indicated by the red arrow) contains an "auxiliary antenna" for calibrating the phased arrays? o_Oo_Oo_O

Could you explain to me how this "auxiliary antenna" is packed into such a tiny space? How it is folded and unfolded? What's the mechanism?

Since you are an expert on the efficient use of space, could you tell us how Noah was able to fit so many animals onto his

Where are you from exactly? What magical realm or advanced extraterrestrial civilization do you come from? Are you like a wizard or something? Can you shrink my mother-in-law?

By carrying this "auxiliary antenna" onboard, I assume you believe the calibration is conducted while the plane is in the air. If so, could you explain to us how this antenna can be safely and effectively deployed while it's being buffeted by strong airflows at speeds of hundreds of miles per hour?

If you believe this "auxiliary antenna" is only used while the plane is on the ground, then may I inquire as to why you think it's wise to carry onboard a piece of equipment that will never be used inflight? Why would they deliberately waste fuel and useful payload on this dead weight?

Woah, I think I've misread your post. By the "embedded box" on top of the "head radome", are you referring to the protrusion on the nose radome (as seen in the red circle below)?

The protrusion on top of the circular array of the KJ-500 should be a SATCOM, or to be more precise, a flat panel SATCOM. It contains a thin phase array on its own that communicates with satellites.

The protrusion on top of the nose of the KJ-500 should be its IFF.
