IAF:
They don't need it. They rejected going for the F-35 in favour of the FGFA. FGFA is better in most respects, plus comes with ToT, 50% IPR etc. So we can modify and produce the jet on our own like we have with Brahmos. If we purchase the F-35, it will only come with MKI style modifications and limited license production. In fact, the Russians had assumed that we will cancel FGFA and go for the F-35 instead, but Parrikar assured them that the FGFA is on. It's better to focus on the AMCA instead.
Even the new Single Engine tender for 200 jets has been designed specifically to keep the F-35 out. It calls for the induction of a proven 4th gen jet, so LM will participate with the F-16.
IN:
There's a new RFI out for 57 jets. LM is sure to reply with the F-35B. It will compete with Rafale and Super Hornet.
