Calls into question the wisdom of going for ELTA-2052 for all 83 Mk1a's (original plan was to cap it at 40, with Uttam for the rest). HAL Chief had said that this was decided keeping in mind the timelines, but the timelines are precisely what are being impacted now
HAL chief has been lambasted in social media for repeatedly lying about delivery dates & sweeping issues under the carpet. That's why he is more cautious now
Uttam is native. So is Tejas and so is Astra. I say we cap ELTA-2052 to just the first squadron (20 aircraft) and accelerate Uttam induction. Our own boys can sort out the integrations issues in record time
I agree, keep it at 18 for the first squadron and later swap them out.
ELAT 2052 is turning out ot be an erroneous choice.
Persisting with it is the Bridge of River Kwai syndrome.
Ramanaji, there seem to be three variants of the Radar for Tejas MK1A/MK2. Initial variant had about 780 or so Transmit receive module. This was improved and a variant with 912 TRM Gallium Arsenide module AESA for MK1A was developed. This will equip the second lot of orders of Tejas MK1A. Then the work on an improved variant for MK2 with 992 TRM is in works that is said to be smaller/compact variant using Gallium Nitride TRM. The current initial prototype testing may be happening with Gallium Arsenide variant of the same. Mostly modified to utilize the extra power available due to F414.
The one that will go on Tejas MK1A https://www.indiandefensenews.in/2024/0 ... tejas.html
Compared to the ELM-2052 AESA radar, the Uttam AESA FCR has better tracking accuracy, a longer detection range, and enhanced electronic warfare capabilities. For comparison while ELM-2052 can track 64 targets, Uttam AESA radar can track 100 targets. In 2015 Uttam was stated to be capable of tracking a target having RCS of 2m square at a distance of 92 kilometers. According to the new reports, the range has been increased to 150 kilometers for the target of the same RCS.Uttam has also been able to track Tejas from a range of 140 km which is quite significant as TEJAS is smallest fighter jet in its category and has good stealth characteristics due to the usage of composite.
The Uttam AESA radar version for TEJAS MK-1A will feature 912 T/R modules. Uttam is a full solid-state Gallium Arsenide (GaAs) based active electronically scanned array (AESA) radar.
Additionally, Uttam AESA radar has LPI i.e. low-probability-of-intercept feature. The LPI will enable fighter jets to employ counter measures to avoid detection by passive radar detection equipment while it is searching for a target or engaged in target tracking.
