I'm aware that the Phalcons use Il-78. I wrote what I did is coz there's no news of the Phalcons post approval by DAC or CCS on further orders & suddenly we've had this development of the DRDO - A-330 combination. Seems to me as if they've permanently dropped the Phalcons for these 2 prototypes.
Regarding the NETRA, I don't see the blacklisting of EMBRAER as a great impediment. Rather, the IAF was more keen on Phalcon type AWACS & as usual weren't too confident on DRDO's ability to deliver that they grudgingly decided to accept 3 AEW's from them, after a great deal of persuasion. Sort of like the via media MP worked out with the LCA - Mk1a before the definitive Mk2 / MWF materialized. Also this was part of the learning curve on DRDO's part.
There wasn't any follow up plan post delivery of the 3 by the IAF. Incidentally, the 3rd NETRA has been retained by the DRDO for further testing. For all you know, post the 26th & 27 th Feb developments, the IAF may just about revisit their stance on the NETRAs & ask for the next iteration. Fingers crossed.
The plan was to operate dozens of Netra. But the plan was shelved after Embraer corruption and the fact that such types of AWACS are not good enough for the needs of the IAF. The Chinese suffered from the same problem, that's why they gave up on their KJ-200 in exchange for KJ-500. They are now looking to sell their KJ-200s. The lack of capability of such a design is why the IAF doesn't want it. So keep your fingers free for something more useful, like a second batch of Rafales.
