MWF (Tejas mk 2) updates coming out.

No, they use the RDY-3. Even UAE's Mirage-2000 upgrades are supposed to get the RDY-3 which is considered the latest iteration of the RDY.

Ur info is incorrect.RDY-2 =>RDY-3 radar.Indian Mirage-2000 uses RDY-2 radar.u may be knowing Air Marshal Raghunath Nambiar who was an Mirage-2000 pilot himself and retired last year from IAF.He was also one of the person who played crucial role in Mirage-2000 upgrade & Rafale deal.hear it from himself,if he can't convince u then nobody can and Tejas for now uses F-404 engine,F-414 is for future variants.

F414 is for Tejas MK2

 

[maniac@666]

F414 is for Tejas MK2

That's the same thing I'm saying, that F-414 is for future variants.u should see his older post to which I've replied to, where he wrote that Tejas is using F-414 and it's advantages.Till Mk1A Tejas will use F-404 engine's.

Uttam Ready

The home-grown Uttam Active Electronically Scanned Array (AESA) radar developed by Electronics & Radar Development Establishment (LRDE) seems to be making the right moves to get the attention of the Indian Air Force (IAF).

With the addition of AESA radar being one of the key features of Tejas MK1A, LRDE hopes that Uttam can even meet the schedules of the upgraded programme.

It has already completed more than 100 hours of flying on a hired aircraft and nearly 25 hours on Tejas test platforms. It is now confirmed that Uttam’s air-to-air mode and its sub-mode functionalities have been already tested.


Uttam is in competition with the Israeli Elta radar and the official word is not yet out on the question of how many Tejas MK1As (total 83) will be fitted with the desi technology.

LRDE scientists are pinning their hopes on the Aatmanirbhar Bharat mandate.

Great news on the Uttam. Total 125 hours on flight tests and A2A modes and sub modes validated.
A2Sea and crucially A2G pending.

 

[MirageBlue]

Yes indeed. It will be a huge achievement to have an indigenous AESA radar operational and hopefully one of the MLU upgrade programs can feature the Uttam AESA. By MLU I mean either for the Su-30MKI or maybe for the 40 Tejas Mk1s.

Watch this interview with Project Director of Uttam AESA radar, D Sheshagiri of LRDE from Feb 2020. He explains that approx. 60% of the radar testing is basically Air to air modes. They were half-way through A2A modes by Feb 2020, and needed 30 odd sorties to complete the A2A modes testing. And now this news that all A2A modes have been tested.

A2G has 2 modes- imaging and tracking
A2S has 2 modes- imaging and tracking

All of these modes were already demonstrated on the leased executive jet, now they needed to show it on the Tejas, which is supersonic and much much more agile.

Plan was to complete testing of ALL A2A, A2G, A2S and combined modes. Out of 18 modes in total, 10 were already shown, so by this year end they should be in a position to show the remaining modes as well. The experience with the AESA radar of the Netra AEW&C has helped greatly, where the A2A and A2S modes were already tested, in operation with the IAF and doing a wonderful job as per user feedback.

Algorithms have been modified from the AESA used on the Netra AEW&C due to the higher speed and agility of the Tejas.

A2G modes have been tested on a Dornier test bed, but in a different band.

We can arm LCA with meteor if our AESA radar is indigenous. MBDA will allow hopefully

LRDE Pushing for Uttam AESA for Last Batch of Tejas Mk-1A

Uttam Radar

The Uttam is an advanced active phased array radar (APAR) system being developed by Electronics and Radar Development Establishment (LRDE) for the HAL Tejas and other combat aircraft of Indian Air Force. Development of Uttam started in 2008 and it was first unveiled at Aero India 2009. Uttam is slated to be a successor to hybrid passive electronically scanned array radar EL/M-2032 currently equipping LCA Tejas. Radar is currently being integrated with an LCA.

UTTAM has capabilities like, Identification friend or foe (IFF), electronic and communication support measures, C-band line-of-sight and Ku-band SATCOM datalinks, etc., similar to those on the AWACS and Conformal Airborne Early Warning & Control Systems (CAEW) systems.

The important modes of operation of the UTTAM radar system are the surface surveillance and the air surveillance. The sensor has the abilities to search, track-while-scan, priority tracking, high performance tracking, etc. In priority tracking, the targets will be placed in full track mode even if these cross the primary surveillance area. In high performance tracking, additional measurements are made to improve the tracking accuracy. Utilizing active aperture technology, the radar provides a fast-beam agile system that can operate in several modes concurrently.

Uttam features an active phased array (APAR) which gives it superior scanning performance over legacy passive phased array radar. Unlike most contemporary radars, Uttam features Quad TRM i.e. a single plank consists of 4 TRMs.

The bolded portion of the text from that article is wrong. The Elta 2032 is not a PESA radar but a mechanically scanning array radar. Also, this article is nothing but a hashing of what Anantha Krishnan mentioned in his article. It simply adds some open source details about Uttam.

Amid border tensions with China, indigenous fighter LCA Tejas deployed on western front

In a significant achievement for the indigenous fighter aircraft programme, the Indian Air Force (IAF) deployed the home-grown Light Combat Aircraft (LCA) Tejas on the western front along the Pakistan border in view of the tensions with China on the Ladakh front.
"The LCA Tejas was deployed by the Indian Air Force on the western front close to the Pakistan border to take care of any possible action by the adversary there," government sources told ANI.
The first LCA Tejas squadron, 45 Squadron (Flying Daggers) based out of Sulur under the Southern Air Command, was deployed in an operational role there, the sources said.
The indigenous Tejas aircraft had been praised by Prime Minister Narendra Modi during his Independence Day speech where he had stated that the deal to buy the LCA Mark1A version was expected to be completed soon.
While the first squadron of the planes is of the Initial Operational Clearance version, the second 18 Squadron 'Flying Bullets' is of the Final Operational Clearance version and was operationalized by the IAF chief Air Chief Marshal RKS Bhadauria at the Sulur airbase on May 27.
The Indian Air Force and the Defence Ministry are expected to finalise the deal for the 83 Mark1A aircraft by the end of this year. In view of the Chinese aggression on the borders, the IAF had deployed its assets all along the borders with both China and Pakistan.
The forward airbases of the force have been equipped to take care of situations along the western and northern fronts and have seen extensive flying operations in the recent past, including both daytime and night operations.

Great development.

Note: Not sure how reliable the info is.

If true then I guess Tejas is at AFS Uttarlai, Naliya will have the MiG-29UPG on a det from Jamnagar(First Supersonics 28)
and so ruled out.
Plus no single engined jets are employed for ops over the ocean as far as I know.
