America’s airborne warning and control system aircraft—or E-3 AWACS—has served it well. But the aircraft’s ageing APY-sensor technology means the US Air Force needs an upgrade.


This article by Stephen Losey, writing for Defense News, makes the following points:
  • The AWACS’s rotating radar dome takes 10 seconds to fully rotate and refresh its view of the aircraft being tracked.
  • Boeing’s E-7A is set to replace the E-3 AWACS.
  • The E-7′s long-range sensor will allow operators to fix its gaze on a target, or even several at a time.
