The dotted line is the perimeter of our best-case radar coverage--we can see a max of 400-500km beyond our borders and coastlines with Greenpine/Phalcon. Fighter (CAP) radar radius is only 100km appx.
Starting from outside this radar coverage, any jet can sneak up undetected upto the perimeter. From there, smaller jets like the F-16 which cannot carry long-range missiles will have to fly right up to the target, setting off the alarm and activating air defenses. But a bigger jet like the Tu-22 can release a couple of
long-range, low-flying missiles (red lines) and turn back just before penetrating the radar screen,
remaining undetected (blue lines). Stopping these missiles would be difficult even if detected, the chief reason being lack of time. In the opening hours of a war, this can be devastating, specially if the Chinese initiate hostilities as they most likely will.
The Tu-22s will likely be used only with long-range standoff missiles for surprise because they will be sitting ducks if caught trying to use short-range missiles or bombs within range of Indian fighters or missile defenses. We are hellbent on making our Sukhois Brahmos-capable for good reason. Well, the Tu-22s are the same thing except with thrice the range and payload.
The situation is worse for Kargil/Siachen, Northeast and Andamans because the TU-22s can use Tibet and Myanmar airspace to achieve total surprise.
We need 24/7 monitoring of the northern Arabian Sea covering all of the paki coastline and as much of the Tibet and Myanmar airspace as we can. The 5 or 6 AWACS we seem to be planning will not be enough even for the Andamans and Kargil/Siachen theaters as only 3 or 4 will be airborne at any time. We need a dozen AWACS with another 2 dozen Embraer AEW&Cs covering the coastline, Indo-pak and BD borders and the area south of Sri Lanka. Instead of messing around with additional Il-76 based Phalcons with their inherrent cost, delay and complications, we should just buy the readymade Gulfstream 550 based Phalcons off the shelf cheaper and quicker as they are as good as the bigger jets range wise.
I may have missed something and am open to correction so if you think differently, please give your reasons.
