Of course, any help is welcomed and the Israelis helped DRDO a lot in the radar field. But first we must get them on board and they need US approval to share anything from the 2052, till then we remain limited to what DRDO develops and before the puls doppler MMR is ready and proven with good performance, it's pointless to put too much hopes on an AESA development.
Still amazed how little use we take from French companies, that will divert similart techs and systems through MMRCA to India anyway and focusing on commonalities, rather making LCA more interational than it already is.
Not necessarily, Rafale, EF or J10B will have AESAs withouth changing the engines.
