Everyone is forgetting the AWACS Phalcon and indigenous that will be rolled out as well the AESA radar on the Sukhois which act as mini AWACS.
Phalcons ain't going to keep the 500+ PLAAF on their own, dude. What we need is AIR DEFENSE. IAF is already burdened enough with aerial duties, clocking around 300 hours per annum. For Air defense we need some serious mountain-based radars covering every 500 km span of distance that borders China in Arunachal, Sikkim, Uttarakhand, Ladakh and Himachal (and wherever we are supposed to be bordering them). For a cheap and effective solution, I don't see SPYDER or S-300s as solution and that leaves Akash SAMs to be inducted en masse and FAST.
If 100% eastern command is covered in the coming 4 years, the MKIs can take a breather; because honestly, thanks to the indecisive and politics-ridden procedures of our government MKIs now have to:
- Do the role of ground air defense
- Do the role of old grounded MiGs
- Do the role of point defense jets
AND
- Run from Western tip to eastern tip ensuring that neither Pakistan nor China take the walk into our airspace.
Making our prime warhorse over-work like that ain't a good thing, you know. There are other fighters/ground systems that are supposed to be filling in these roles.
