Thus far nobody has found a similar tower in the white or gray world, so it is hard to comment on what it does with any authority. We know it rotates,
based on different photos (mostly google earth time snap shots). But we don't know how fast it moves since nobody has been on Tikaboo and watched it
Radar doesn't have to be done with dishes. For years they have used phased arrrays. [Beam forming for those that have studied DSP.] So a flat tower
can certainly be used for radar. Why it would have to rotate is a good question.
The aircraft at Groom have their stealthiness checked in (at least) three ways. One is a static radar cross section (RCS). That is where the plane is
put on a pole and hit with microwaves, then the reflections are measured. One theory is that the new large hangar is just an enclosed static RCS
facility. Second is dynamic RCS, which can be done with the Dycoms or the Lincoln Labs N105TB aircraft. This is to check if as the plane moves,
something is reflecting radar. [Door seals, control surfaces, even the exhaust plume.] The third test is the infrared signature of the aircraft. Some
suggest this is done from the Papoose Mountain facility. Now it is possible this triangular tower is a phased array radar, perhaps doing dynamic
Note that you shouldn't be hot-linking images from Dreamland Resort in the ATS forum. That is copyrighted material. Remember, "fair use" is a legal
defense, not a right. It would be fine to post a link to the page that contains the image.
I can get away with hot-linking my own links here since I'm the copyright owner.
I don't have a bandwidth charge, but many websites do, so when you hot link their image, they incur a charge but don't get the benefit of adverts
(if they use them). More at
I have been known to change images that have been hot-linked, usually to a the arse of a donkey (which technically is the arse of an arse).
I have a thread on ATS about Michael AFB (Dugway) being used as a UAV facility. It is not a secret. Of course, what they do there could have some
secrecy since it is remote. The Gorgon Stare was test at DPG. So yes, stuff is going on at DPG, but that doesn't means nothing is going on a Groom.
Every year the place gets bigger. Eventually they will be running more power to the base (new power lines from the east).
