These are the hopeful expectations of project managers - they do not reflect reality. Reality is that Elbit and Elisra were selected L-1 in RFQ for radar and EW suite respectively.

Going by what these same type of hopeful project managers say, one would also be lead to believe that the last 2 Kalvari-class subs will be fitted with indigenous AIP. However, reality hits these extra-optimistic claims in the face later on and then they double down on the claims.
Only pipedream radar here is UTTAM. It is years & years away from being operationally certified. Neither HAL nor IAF wants to delay the Mk-1A program till the time UTTAM is ready (which could take 5 years or more).
Elta 2052 on the other hand, is already been fitted on Jaguar DARIN-3, and it was a fully operational system even prior to that (otherwise it would never have been allowed to compete in the RFQ for radars).

You can find scanned copies of the relevant RFQs that called for procurement of radars & EW suites here:

But I don't see what's the point in trying to educate you with facts considering you seem to have no intent of following them and insist that we all live in a la-la land imagined by over-enthusiastic DPSU personnel, who would have us believe Kaveri would power the IOC Mk-1 itself (remember that was the original intention long ago).
