In fact they don't need to.
There is a net of satellites with GMTI have today so damn good high resolution that they could eventually start making AMTI (that means to shift or simultaneing Around Moving Target Indication to Air Moving Target Indication). That means that today there are technology enough to use systhetic aperture radar surveillance to search enemy aircrafts. To the point that E7 Wedgetail was cancelled (E3 replacement!).
So USAF or US Navy won't need and AEW in future.
Probably China has something similar and can provide early warning to Irán without having no AEW aircrafts.
Anyway It would be desirable to have an AEW and some generals of IRGC said that Irán has even purchased also AEW aircrafts, something dubious because even Russia has struggles to build one.

| Shifting the air moving-target-indicator (AMTI) and ground moving-target-indicator (GMTI) missions to space also presents formidable physicschallenges inherent in tracking such targets from great distances. But military officials believe they are making progress. Satellites equipped with synthetic aperture radar have been performing AMTI tasks in orbital demonstrations, Gen. Gregory Guillot, commander of U.S. NorthernCommand and North American Aerospace Defense Command, said recently (AW&ST June 2-15, p. 17). |
