AWACS - what do these antennas do? In a press release for a new Boeing "wingman" (BATS) drone being built in Australia, a closeup of this Australian AWACS flying in formation was provided. What would be some of the specific uses for the antenna farm located all over the fuselage?
The image below labels each of the antennas. To summarize based on your groupings:

A: Multi-Role Electronically Scanned Array (MESA) made by Northrup Grumman. It has a similar role to the large rotating dome on the E-3 in tracking airborne targets. Instead of being rotated mechanically, it can be electronically scanned.

B: Communications/Navigation, GPS, ELT (emergency locator transmitter)

C: Missile warning, infrared countermeasure

D: Electronic surveillance

E: Communications

F: Communications

G: Communications/Navigation

H: Missile warning, electronic surveillance
