Flighthappens... Isn't AESA just the way the radar transmission is directed. It doesn't necessary mean it has more power, or displays data better in the cockpit or has a better user interface. Then there's using link16 to display the big picture instead of the aircrafts own radar.
Maybe Oman has no requirements for Brimstone or cruise missiles? Typhoon and PW4 has still delivered on Ops.
In my opinion, anything that keeps 1000s in a job at Warton and keeps their local economy ticking over, is a good thing.
