There are hoops to jump through, before India could get the F-35, The Russian S-400 has to go, for a start,
Even when given all the evaluation data, There is a lot missing, including the true RCS, Only when a purchase order is placed, The classified, full data is given for all systems and this is only to a few classified air force personnel on a need to know basis , It's not even submitted to the Government officials,
Our government and head of the air force, doesn't know what some in the air force know about the F-35, it is very secret, This applies to all military equipment, Secret stuff generally remains secret, except to a few
It would be true that at this point, Indian access is very restricted,
They don't have a downgraded export version, like the P-8 and E-7 etc
