The Pentagon’s device encircling Iran not only includes the expansion of the Bahrain military base in order to station its F-22 bombers  [1], but also a mesh of X-Band radars, enabling it to monitor the Iranian air space.

The radar observation bases are located as follows:
  Mont Keren (Negev desert), Israël 
  Kurecik, Turkey 
  Non-identified base in Qatar 
  Al Dhafra, United Arab Emirates 
  Camp Arifjan, Koweït

These bases are permanent and lasting constructions are in progress.
