Australia is already looking at a Wedgetail replacement. Forethought, planning and early public disclosure - can't see that happening here.
The Australian Department of Defence (DoD) has confirmed some of the broad outlines of the replacement of the Royal Australian Air Force’s (RAAF’s) Boeing E-7A Wedgetail airborne early warning and control (AEW&C) aircraft.
A DoD spokesperson told Janes that the Wedgetail Replacement project, designated AIR7002 Phase 1, will commence in 2029. At that point the programme “is designed to begin scoping and risk reduction studies, informing potential platform replacement and technology options for the E-7A [Wedgetail]. The replacement of the [E-7A] Wedgetail fleet will begin in the second half of the 2030s.”
