Which bit of the article is complete garbage?
Well, Mossie's bit about Tennis Balls and "state of the art" for starters!
He should know better as RADAR is not his specialisation - Driver Airframe is! AN/APY-2 uses doppler and fast-fourier techniques - hardly "ping-pong divide by 2"!!! The RADAR is good but it is still 1970s technology that had a mid-life (RSIP) upgrade in the 90s. If you want state of the art for AEW&C then look at NG's MESA RADAR on Wedgetail or some of the ELTA RADAR equipped AEW&C aircraft.
This is just a shameless plug and appeal to the Public to make sure we don't lose Sentry like we did with ASTOR and our replacement MPA in SDSR. That said, losing Sentry would be a complete disaster for all 3 services.

PS. Other garbage: exercises over the Falklands are hardly a common occurence!
