I would like to advise to refrain from making potentially escalatory posts in this thread...

hope AMCA follows the same concepts of stealth. o/ Jai hind!
AMCA is a fighter jet not helicopter the geometric stealth is pretty obvious in the model it will also have internal weapons bay

Upcoming tableaus this 26thInterestingly there's also a TASL ALS 50 in the tableau.
Please provide some commentary going forward - picture only posts(as well as twitter/youtube only links) are generally frowned upon and encourage low effort and low quality posts.
I'm curious what foundry in India makes semiconductors for TRM's .
The Uttam could be an actual good baseline for those multiple types of fighters. the Su-30 offers considerable amount of space and cooling potential for the AESA's.

Su30mki will use upscaled version of UTTAM AESA Radar under super sukhoi upgrade program

Yes we have been hearing about the AESA-equipped "Super Sukhoi" program for .
Yeah. The potential is great tho i'm kinda wonder on the mass production side of the AESA TRM's for India. The baseline Uttam have about 780 TRM's the Mk-2 have some 912's. mass production will considerably reduces cost if Tejas and "super sukhoi" are to use common TRM's.
Simple back of envelope calculation i did which assumes 9500 MHz center frequency and twitter post depicting Uttam Mk2 antenna, suggest some 87% "fill efficiency" for the Uttam Mk2. Means how much the antenna area is occupied by the TRM's compared to the "empty" area, designers will seek to maximize this to pack as many module as possible.
Assuming the same "fill efficiency" for Su-30 sized Bars.. which have antenna of about 1 meter in area, that would give about possibility to fit 2754 TRM's or about 3 times the amount of Uttam Mk2's. The range factor will scale by 2.29 Times, the cooling load is also scaled by 3 as well as the estimates cost of the radar.
As far as i remember the Uttam mk-1 was credited with about 150 km against a target (afaik stated to be another Tejas prototype) The baseline has about 780 TRM's scaling up to 912 will give range factor of 1.12 or 12% increase in detection range of the same target, brought the range for 912 TRM variant to be about 168 Km.
Flanker sized airframe with 2754 TRM is therefore capable of detecting same target at 384 Km, exceeding the baseline N011M Bars or Bars R by quite amount of margin and would rival or exceed Irbis-E and APG-82.
