It is not very useful for India, there are sats now for recon.....and sams have come a long way. Good use for Russia...
I am not saying that if we buy MiG-31 we should use it only for Reconnaissance and Surveillance purposes. MiG-31 can also perform long-range interception, precision strike and defense suppression tasks.

Lastly we can Talk about it in the Dedicated MiG-31 Thread. This thread is for Discusssion of Tejas MK-1 and MK-1A. Thank you.

True

But even then there is slight advantage. An aircraft with high dry thrust also ensure less use of afterburner and low IR signature turns into better fuel economy advantage in dog fight etc.

Having said so even with no supercruise a decent radar BVR capability is more than enough. It's not like we are going to use Tejas in high payload strike role and even if we do there will be escort too.

The bottomline is how you use and fly your aircraft is equally important.




Yes that's true... That's where experience in designing craft come into play. If you look in

The mk2 will definitely improves on that but then there is always a limit.

The GE F414 won't provide the thrust required to do so .
ADA Designers says this. Havier Gripen with same engine does that. Any reason why MK2 can not do that?

Despite being longer in length, Tejas mk2 will have lesser empty weight than mk1 as per DDR. Link👇

Amit Kashyap also told the same in yesterday's video. So with same engine and 1000 kg lesser weight than Gripen, why can't it supercruise?

Already explained if you care to read bro...

Mostly marketing tactic that's it. What was the payload when it showed supercruise capability ?

Both are designed differently aerodynamics have a role to play too And Gripen may have gain from Saab experience and design to have better aerodynamics less drag etc
but don't believe what their brochure says it's mostly gimmick.

Mk2 will have supercruise capabilities. This is said be a scientist involved in MWF programme. MWF is a highly optimised design for weught as well as for aerodynamics. Nothing in the catagory can match MWF except Gripdn NG. Don't underestimate MWF design.
There is no concrete evidence anywhere that Tejas Mk.2 can supercruise. It might do carrying no payload. I shall wait for official release. The supercruise section for Mk.2 has been edited/removed in Wikipedia on 4th Mar.

Imagine if India had MiG-31 in it's Inventory, it could have been so good. MIG-31 has a very powerful radar and can be used as a mini AWACS.
In the 2006 India retired Mig-25. The Russians offered Mig-31 as replacement. But we didn't show much interest. It was during UPA-1 time. The main focus of IAF then was on MMRCA programme.

mig 31 has older radar ,even if we upgrade su 30 mki with uttam aesa GaN then its range will be higher
Is the UTTAM (the one intended for the Mk.1A and who is already flying on 2 Mk.1 airframes) intended for other aircraft? (SU-30, Mig-29, etc) how does it compare to the radar they already use?

Standardization with the radars seems as a step in the right direction.

Another version is already developed with more tr module , wait for def expo for more info

ukkam GaN mk2 with 975+ modules is in making for mk2 ,that will be scaled to 1200 modules for su30mki

" but each Tejas maintained 6 sorties per day! A remarkable achievement for a new fighter jet" <-- What are comparable numbers for other fighters?

Where... Can you share the quote... Even then take it with a pinch of salt and at best it might be similar gimmick at end.

A light fighter in such excercise can definitely provide such no. Of sorties but it's good to see that provided proper spare support and maintenance Tejas can do the same.

The real question would be how much maintenance manhours etc is needed.

Whatever may be the case it will only improve for mk2

We can do the same with our Flanker... No need to shell out additional money for mig 25 or 31 anymore . That's why IAF decided to ground Mig 25 after we got our hands on Flanker.

It's speed and altitude it can operate does provide certain advantage though for interception.

The reason IAF Retired the MIG-25 is because the Foxbat's only role in the IAF was Reconnaissance and Surveillance. Later When Satellites came to be and could do these roles, Better, cheaper as Compared to the MIG-25.

So hence IAF decided to retire it. Also the MIG-25 Required lots of Maintenance and was expensive too. So Sukhoi SU-30 MKI has nothing to do with MiG-25 getting replaced as far as I am concerned.

Well Mig 31 is essentially an improvement overthe Mig 25 so as you have requoted satellite made the reconnaissance part useless.

Other advantage was speed where Mig 31 only excels to intercept big radar etc.

Well Sukhoi provided more... Big radar can intercept with long range missiles and unlike mig 25/31 can dog fight and provide air superiority.

So Sukhoi essentially ended the need of Mig25/31 other advantage too.

Regarding maintenance if we really needed it we would have maintained it somehow or bought mig 31. But with Sukhoi and satellites etc there wasn't much need.

For Russia having such a very large territory it might be meaningful to still have them.
