That's why some stupid people questioning rationale behind using older platform instead of brand spanking new is well....stupid.These guys are just stupid. A330 is far bigger platform for AWAC and so is IL-76. IN P-8s have far more stations for controllers than IL-76 based awac. Even A321 will have extra space. Every five years the size of electronic devices reduce by 50% and their capabilities increase 200%. What was good in 2010 is not the norm for 2025.
The original DRDO AWAC was based on Avro and had the chapati on top. Why cant an A321 have it. I will rather go for B737-800 as the platform because IAF already flies B737-700s as VIP Transport. We will have similarity of type training for pilots and also spares and also commonality with IN P-8s.
In the next 10 to 15 years electronics of existing AWACS platforms will be next to useless and will be needing almost new hardware and then we can bring entirely new designs for more convenience. these AI jets are avilable right now and can be converted rapidly instead of waiting for new jets probably for years
PS: its definitely going to be rotodome as shown by DRDO CABS in Aero India
