HAL statement said that the radar will first be tested on Mark 1. This MOU also mentions "Mark 1 & Mark1A"........ Plus they're already working on Uttam Mark2.
If you remember, around April or May this news was out. HAL and DRDO was about to sign MoU for UTTAM mk2 varient where HAL will build 2 set of EASA radar in next 36 weeks for testing and further evaluation on LSP ( LSP are actually mk1 ). This Radar will be production varient for Tejas mk1a and Tejas Mk2.
I think, this MoU are finally signed now.
UTTAM mk1 had around 700- 786 TRM which was just a technology demonstrator only. The production varient will be Mk2 with 900- 1000 TRM which will eventually go into Tejas mk1a from 21st jet.
Tejas mk1 are scheduled to deliver by March-2022. I don't think by this time UTTAM mk2 will be fully operational.
Still, I could be wrong because these days PSUs are showing great synergy.

atleast the mk1 Uttam AESA shud be added to the IOC standards to bring them at par with the FOC...besides, if mk1 uttam is atleast better than the cinese KLJ-7...IAF shud stop acting like a rich man's kid and just use it

Little confusion about UTTAM and its variants ( currently ).

UTTAM mk1:- This is a TD only for testing. Has low TR modules. One can put it into production but will not be suitable or adequate when Tejas can use AESA with higher TRMs. Hence, LRDE came with UTTAM mk2. This is not a mistake but a process to develop a product.

UTTAM mk2:- This is a production variant that will have more refined software and compact TR modules. This ultimately will go into Tejas Mk 1a, Mk2, and Su-30mki ( upscaled version ) or even somewhere into Tejas Mk1.

Both above versions are based on GaAs.

UTTAM mk3: This will be a GaN-based high-end AESA Radar, which will be developed by 2028-30 and incorporated with AMCA and subsequently in Tejas, Su-30mki, or even IAF darling " The Jaguar "

Tejas MK1a - Uttam AESA 780 TRM
Tejas MK2 - Uttam AESA 992 TRM
Su 30 MKI - Uttam AESA Nearly 1200 TRM
All GaAs based. This was the initial plan. Havn't seen any change mentioned. The 900-992 Module mentioned development was for MK2 as it will be with F414.

Seeing as the Super Sukhoi upgrade is still being delayed and there are no negotiations with Russians for new engines, isn't it prudent to leapfrog directly to GaN AESA made by DRDO whenever that upgrade does happen?

Super Sukhoi will be done in form of multiple smaller upgrades and timeline for upgrades will stretch. If upgrade is postponed till late 20s then it makes sense.

These guys at IDRW always jump the gun.

Malaysia would have indicated in the RFI that they would want to go with a barter trade agreement with WHOEVER wins their competition.

It would apply to KAI, Alenia, HAL, all of them. HAL is just preparing it's bases as it needs to provide clear details of how such a barter agreement would be executed on it's end. Hence the MoU. The MoU means nothing if the Tejas Mk1A isn't selected first.

i personally do not believe we were ever in the running...i mean did anyone really think that india was going to win against the massive nexus between their lawmakers and arms industry? that too when the lockheed martin is invested in the T50 trainers themselves?... India's bid to USA was more about making a statement of confidence to global clients-to-be...in the west, the fatc that we have made our first aircraft carrier, etc...barely makes news...well drdo did the right thing because thats how you get attention of the smaller fish in the barrell and show them that they need not compromise with chinese junk and can get close to USA without really being close...
agreed. It was a VERYYYY long shot.

Without tying up with a US manufacturer first, there is simply no way that the Naval LCA Mk1 trainer stood a chance.

Even KAI, which had already won some exports had to first tie up with LM before offering the T-50 to the USAF for their trainer requirement. Same with BAe which offered the Hawk.

And even there, despite being mature, political and industrial considerations meant that a clean sheet T-7A design between Boeing and Saab was chosen. Primarily to protect Boeing's fast jet capability which was on the way out with Super Hornet and F-15 (back then) not finding more favor. Now things have changed with export contracts for Super Hornet and the F-15QA and F-15X. Of course, Boeing's deep pockets meant that it too was able to offer the T-7A at a very low cost that even LM couldn't match.

There will be a requirement to build the trainer in the US as well..which again is not possible without a US partner. Northrop or Sierra Nevada were possible contenders but HAL doesn't seem to have made any attempts to tie up with anyone in the US to build the Naval LCA Mk1 trainer there.

So all in all, this was likely done just to please MoD bosses and political masters that HAL was trying it's best to secure exports.

payment arrangements need not be disclosed at the earlliest...by my common sense..if i go to a paanipuri waala and say that i wud pay him in high-5s(just a stupid example dont take seriously) which he can cash-in later at some other portal...he wud chase me away...or atleast not bother selling that to me...among the lot...Tejas is definitely more bang for the buck...if they can make a deal in palm oil they can only do so with india given that we have the capacity to absorb that kind of volume...and certainly one of the largest export destinations which forced even Mahathir-mullah to change his colors for a while...however the folks at IDRW do not only exaggerate, sometimes they also mis-report facts out of thin air...if a deal is to happen, even with a clause of palm oil import...it will happen when it happens and we shall come to know about it...get ready for the 'samosa in palm oil' jokes from the urdu speaking punjabis!

No shit.. Everyone here knows that (ok maybe not everyone).

But yeah, the fact that this option is there makes our odds better. India is the greatest import market of Palm oil & has been giving cold shoulder to Malaysia. They might wanna change that.
