DRDO produced the Netra AWACS which entered service with IAF in 2017 for a princely sum of 3 planes.
IAF didn't want any more, but after "Swift Retort" from some piggies they suddenly wanted more, but the problem is the model Embraer jet on which the Netra radar is mounted is now out of production
There was another proposal for more IL-76 mounted Israeli radar but nothing has been heard about it since years now, 3 of these are already in service.
So now DRDO/HAL have to do both, get a new plane for the Netra radar and make another bigger AWACS with a bigger and better radar.
Anyway the Padosi Mulk's airfields can easily be blasted by our missiles before their F-16s ever take off, it's quite a thin country geographically
