This is an important point which gets overlooked at times. With satellite imaging and enough image processing power India should be able to identify and track surface combatants around its coasts and even in deep ocean.IN has benefitted greatly from the latest imaging and navigation satellites made by ISRO.
I have "heard" that Chinese have been greatly interested in this for long and have been doing quite well in this field as well.. in fact I remember reading an article in a us defence journal associated with joint staff a few years earlier about this issue and potential problems because of it for fleet movements etc.
To be honest I enjoyed this 'windjammer style' reply to that idiot. I decided not to argue with him as it looked useless. To summarise, to one of my pose he raised a useless argument that 4 AWACS are not enough to cover a about 700km coast. I replied back mentioning that IAF actually operates just three (I added 2 in testing to make it more 'comfortable'). But that indian troll I think could not digest this so ended up posting vitriol about su-30s as mini-AEWACS. Which is bullshit, a fighter with long ranged radar isn't equal in functionality to an AEW & CS platform.Of which at best 70 can actually fly at a time due to both maintenance and personnel issues.
What do you think about mini-awacs?
And you did not reply back to my question in another thread.. I thought it could result in a lively and enjoyable discussion..
