According to SIPRI, we purchased one EL/M 2052 radar for the LCA program in 2009. It further states that the reason for the purchase was because there was no headway made in the indigenous program. There are no other details, so information is sketchy since LRDE did say they need a partner for the AESA radar.
Anyway, LCA Mk2 was always planned to have first flight in 2014, that's because the F-414s were still being developed at the time. Now first flight is expected in early 2015, that's a good enough time frame.
SIPRI is a very reputed source but according to the other reports, Israel did sell one 2052 in 2009, but the destination was unknown. It could very well be India, but nothing concrete is available as proof.
At that point of time the LRDE did indeed state that they would go for foreign consultants for the AESA for LCA mk2. That was 2009-2010. And suggestions/rumours/reports are there that they did manage to get Israeli assistance to AESA progam, much like the low profile manner in which they helped in developing the swordfish derivative of Greenpine.
The mkii requirements and performance characteristics were drawn up by 2008, and at time too GE F414 was touted to be the engine for the mkii. The f414 was under development sure, but only to improve fuel economy. There were already engines being supplied to the USAF/USN by then. The mkii was envisaged to make first flight by 2012, but as usual, slipped once the mki slipped from 2010 to 2014-15.
In a way, the 2017 timeframe for squadron level production is very achievable, especially since the SU30 would finish production. Not that there is a direct link, but more attention and funds will be diverted to lca and the Rafale, hopefully.
