Maybe some EOTS imagery also?

3. The AN/APG-81 radar system uses AESA technology and S-band frequencies for early detection.

It looks like a professional site, though...but, Is it mere write mistake? :roll: (Is S-band wrong and X-band is correct? I'm not sure...confusion... :roll: @@@)

I don't think they welded it close. :mrgreen:

There has been some patents describing an X-band radar system with wider band EW capabilities:

EW I can believe, but not for "early detection" as stated by the author. The antenna is just too small.
