Any ideas how many T/R modules the Uttam has bro?

The prototype has 600+.

The prototype has 600+.

Not bad for such a small fighter with such a tiny nose, the RBE-2 on the Rafale has around 900.

@Levina @PARIKRAMA @Robinhood Pandey @randomradio another look at ARDE's Corner Shot (with the MCIWS next to it):

10+22+30+30+30+30+22+10 = 184
So 184 x 4 = 736 T/R Modules

This gets further verified with this

Look at mounting pad stat..

Wow, 700+ is very respectable indeed. To think, the LCA could be one the first IAF aircraft with an AESA radar is quite something really


( I'm pretty sure the IAF's Rafales will narrowly beat the Mk.1A into service)

Very true but MK1A will come with this one

This has approx 1200 T/R modules..

Judging by Tejas Nose cone of 650 mm, if we can apply a good cooling system for heat dissipation, we are looking at very good radar range improvement. If we are successful, then perhaps we may see 2 m2 RCS at around 150odd KM.. Which is really good bcz ultimately 1m2 will be above 100 km and LO/VLO range of detection will be better than present 100 km Uttam case for standard 2m2

Of course, heat dissipation is not going to be a easy task.. I hope Israeli folks pitch in along with say some liquid coolant tech to use the radar at max range..

Yes, made by ARDE:

Yeah. Too bulky at the moment. Eagerly awaiting their LMG. I have a feeling it's already been through limited trials.

I understand the ELM-2052 is being fitted for the MK.1A but do you see the Uttam being operationalised or is it just going to be a tech demonstrator for more advanced derivatives later?

The LCA's nose is bigger than the Rafale's. Anyway, RBE-2AA has more than 1000. Technically, LCA can carry a slightly bigger radar.

...or even, the same size of radar, but with smaller T/R giving a higher total count.

Miniaturization of the TRMs is an ongoing process and if we can achieve the same level of progress as the Russians did (from the Zhuk-A to the latest FGA-29/35, wherein the radar size remains largely the same but T/R count gets higher), we can expect close to ~1000 T/R on the Uttam once it comes to production.

But ofcourse it is not a very easy process (especially the cooling part), and it's gonna take some work to get there. But you can trust the forces to never induct a half-baked product, so....

They've renamed the, "MCIWS", to, "Advanced Assault Rifle".

The Uttam you see today is just a prototype. It is currently equipped with GaAs modules, so those will be replaced with GaN by the time it is ready.

Uttam will be deployed surely and it wont be a tech demonstrator.. IMHO, the limited LCA Tejas Naval variant which will see a around 40-50 jets or 4-5 squadrons should see usage of Uttam.

Over seas, the light weight aircraft primarily going against hostiles in A2A mode as well as AshM mode for ships will see LCA naval engaging fighters more of 2m2 approximate RCS. Of course the radius of action would be limited anyways. This is where i see sureshot scope of Uttam deployment.

Anyways the Naval platform of Tejas and uttam both gives us sufficient data which can help us for AMCA and a much higher end derivative of Uttam series for the AMCA too..

So i really think it cannot remain as TD but has to be operationally deployed for the program evolution and creating self reliance in the field of radar

The old design's turret could also elevate -

Elevating the turret launcher to that small height does not really provide any benefits wrt to range or target acquisition. It was probably done because the earlier design couldn't properly point upwards without greasing the hull. Indeed that's unnecessary now with the hydraulics modeled like those of a tipper (a vague comparison), instead of elevating the whole launcher on a central cylinder.

Also, in the earlier NAMICA's case the hydraulic cylinder-shocks are on the sides, which is a danger spot. Easy to lose in case of even a firearm hit. The latest design puts them underneath the launcher while the smoke-grenade dischargers have been moved to the top of launcher-side. An excellent design consideration!

Won't elevated turret provide additional capability of firing at depressed angles?

It may be beneficial when firing from a high scrap.[/QUOTE]

If you look carefully present uttam AESA is 600 mm dia whereas LCA nose cone can accommodate 650 mm dia .......not to mention that uttam AESA is TD not actual radar so 736 is initial T/R modules ...so we might see more powerful Uttam AESA in future with near 900 TR modules
