RIA Novosti:First Russian AWACS plane put in service with Indian air force
India dropped Russia from a $1-bln tender to supply six aerial tankers for the Indian Air Force due to poor after-sales maintenance services and is most likely to look for another manufacturer for future AWACS orders to satisfy its needs for early warning aircraft.
Just as I had expected. My bet's on the Israeli Gulfstream CAEWS 'Eitam'
Difficult to say... it will most likely be a JV between IAI for the CAEW Tech, to be incorporated into the AEW&C Phase 2 project. Both the present MoD (Top brass, not babus) as well as DRDO are pushing for this... and given a year, once IAF sees the final array for AEW&C, they will also be ok with it - right now, they aren't averse to something like that.
In fact, simultaneously, Eitam is also being pushed as a JV for technology, in case they aren't able to make a clean sale. Technologies we need/are looking at are - Battlefield management & Combat control, ground control and detection, interface between air and ground, better networking - in a nutshell, turning the AEW into a complete command centre, which can handle the war on the ground as well...
As of now, the operational doctrine that is being developed for AEW is to have Phalcons (6 nos) as Theatre level controllers, with the smaller EMB-145s weaving in around the Phalcon areas to provide continuous coverage for areas of importance, on demand by the local commander. This includes Army commanders as well (the joint op doctrine and heirarchy is being looked at - don't wait for it).
In wartime, they are expecting around 2 Phalcons in the air at all time (for 24 hr ops at 500 km, we need around 3 Phalcons and 5 crews, from the CAEW presentation calculations), with around 4 AEWs around them. That means that we'll need around 5-6 Phalcons, and 8 AEWs for 1 front. The rest will be handled by ground radars.
Can a really big AESA be used as an offensive weapon? There are prelim reports about its useage in a high speed data transfer role.
Yes... it can... electronic steering means that you can direct the rf energy in one direction to jam or interfere with the enemy's radar return, which will make him effectively blind. Its like shining a torch into someones eyes. The problem is that your torch needs to be bright enough, or else, it willl only let the enemy know where you are (not that he already doesn't). The issue is whether ur algorithms and hardware supports it. WRT the Phalc, I don't know. But we are definitely looking for this capability in our AEW, especially in generation of custom waveforms and fast pencil-beam generation.
Just to let you know, as already mentioned, the info about AWACs is really guarded, but speak to a few people and you realize that everyone is working towards that little extra edge, given the furious pace of electronics and ECM development... our own guys are trying out stuff to get much higher accuracies, stuff that doesn't appear to be on present systems in Public Domain knowledge. Its just a continuous race to adapt and improve.
Coming to comm...The data rates from American Fighter AESAs are around 248 MBps (and thats only the reported number)....

Ok fine let me understand this the so called TG is a combination of DSP and Software Algorithm . An AESA radar of Phalcon can act as Transmitter and Receiver , DRFM is again a combination of DSP and Signal Generator.
Now one can just use a small portion of AESA and generate the necessary ECM technique and DRFM type jamming , what can stop these AESA from being converted into Multi Function system ?
Nothing at all.... which is is the major advantage of AESAs in the first place. Ur AESA functionality is only dependent on the signal processing power at ur disposal. Do note that ur array and TRMs are quite versatile, but to actually get the interleaved modes, a lot of processing power is needed in parallel - this adds hardware. Its a trade-off.
