Somewhat interesting in that the Pentagon did not want the E-7 (as a replacement to the E-3):

nominally because it wanted to spend the money on more E-2s, which can operate on smaller and rougher airfields, which would be handy in (e.g.) the Pacific where tiny islands don't necessary 'fancy' runways that the E-7 needs.

But they're actually very handy in tracking tiny targets—like drones—so Australia is sending E-7(s) to the Middle East:

Congress rebuffed the Pentagon's attempted to 'completely kill' E-7 acquisitions, and the USAF has now put in an order, and it may be that people now realizing having some number of E-7s may be handy:
