I sometimes find this thread hard to follow!
Interesting to go onto Google Earth. About 32.2 miles west of Tehran (261° from the red star that marks Tehran) you will find the Bid Kaneh compound. Good detail on this picture. Now follow the road to the south and you'll find some very interesting stuff in the desert. Fairly obvious what most of it is.
To the east of the compound you'll see a road that disappear into the hillside. Plenty of earth covered shelters. No obvious launch site.
