I see the Wedgetail has up to 12 consoles (RAAF apparently have 10 consoles at the moment).
I accept the E-3 is the standard by which others are judged, but given development, the newer/smaller aircraft are possibly very capable as well. However, I have no detailed info.
RAAF couldn't afford E-3, despite lusting after it for many years, and had to wait till an affordable solution came about given advances over time? How close to E-3 capability I can only speculate.
