Please see the article I posted above.
EL/M-2052 + Israeli SPJ ---> Mk1A
Uttam (and probably a DARE solution IMO) ----> Mk1 replacing the EL/M-2032 Hybrid & as there is no jammer presently.
So a 40 unit order will be there.
Now, why is Uttam not directly being chosen for MK1A? Because there is no time.
Radar installation & testing is a very involved and arduous affair because they will now have to package the radar into the LCA (even if it is designed for it) and check the performance of the software & hardware at much higher speeds and G tolerances. There may be HW failures. The S/W may need tweaking (especially A2G modes).
Then there will the interface with OAC which will need to be checked against weaponization.
All in all, 2 years after installation on a fighter is a very aggressive schedule.
From the HAL perspective, they hate any changes, not even a small screw can be changed until & unless it is done well ahead in time.
So they want a proven system right off the shelf, and zero last moment changes.
MK1A is due, what 2022? So that means they want to spend all the time in fixing/tweaking an available system which is already flying on the DARIN-3 and get it to perform well enough for IAF requirements.
As long as Uttam goes into production, we need not worry.
Lets look at what one requires for an overall solution for a WCS (aka Weapons Control System:
Sensors - Radar & IRST -Uttam & Dual wave IRST for Su-30 upgrade
Mission & weapon computer: Huge experience, including the OAC on the LCA Mk1
Navigation: RCIs RLG-INS has now been cleared for production & expect a LCA/AF specific version soon; Combined GPS/GLONASS/IRNSS receivers will also be easily integrated.
Weapons interface modules: Already on LCA to interface with different systems
Indian made weapons: Astra Mk1/Mk2, Garuda, Garuthma, SAAW, NGARM, SANT, Nirbhay Air Launched, Rudra M-2/M-3
ESM/ECM suite to work well the RF sensor: Tarang has been fixed on the LCA Mk1 per latest Parliamentary report & the D-29, DARIN-3, Su-30 HBJammers are all being developed in parallel.
Visual data processing and display: Several firms with flight qualified gear using commercial AMLCDs, including SAMTEL.
So since a complete package is emerging, you will see the IAF push to retrofit the Uttam and variants on even the MiG-29 as part of a 2nd MLU. I would even presume, some of our Su-30s may see an Indian AESA fit.
Right now, lets take a look at what's happening with the LRDE radar scene beyond Uttam.
The LRDE has 2x AWACS programs & a MPA program to continue to work on airborne radars. It now has access to a bizjet testbed to fly out its FCRs. It has 2 sites where it can do a lot of heavy lifting regarding ground testing. The hardware part has been tackled via MPR, LLTR wherein we didnt take any tech assistance regarding how to handle the signal processing or any of the complex RF side stuff. Which leaves one more crucial thing, the all-important TRMs which need to be mass manufactured to drive costs down & get experience.
Again, this is happening via three programs. QRSAM, ADFCR aka Atulya and an unnamed program, which I believe likely exists and will use X-Band TRMs.
This, along with DRDO's efforts to operationalize GaN modules mean the power density & packaging side will keep pace with software tweaks, and hence a range of radars based off of Uttam may be available for the next tranche of fighter upgrades.
So things aren't bleak by all means. Significant progress but without the glowing PR that western programs get in trade journals.
Apart from DDR, I can't really cite any desi-media with half a brain or continued interest in the topic.
