HAL Tejas

On 31st april first 2 Tejas mk1A will be delivered to IAF. According to Jane's media's source in hal.
Most likely those are almost ready to be delivered but awaiting for Modi To limelight event.

If we see the second video it seems that engine failed. as plane was stable everything was fine..
Engine seems ON. Bust most likely wasnt producing enough thrust to keep it in air.
 
 
There is a surprising amount of washout twist in those wings. Look at where the leading edge contacts the fuselage versus the trailing edge, and look at how the wing twists to reduce the angle of attack outboard.
 
Is there a definitive breakdown about the differences in Mk.1 to 1A? I always thought 1A had long flown and that it was the version which introduced A2A refueling.

Mainly avionics changes. The two big changes are a new indigenous flight control computer based on PowerPC architecture and the ELTA 2052 AESA.

Other changes are SDR comms systems, RWR, provision for jammer pod, new cockpit displays and expanded weapons clearances. Indigenous content now 50%.
 
Main difference is they added composites into the wings to reduce airframe weight (Mk1 and Mk1A really struggles with weight and cant carry a full external payload in combat conditions), added an Israeli multifunction AESA radar (though doesn't have multifunction mode in the Tejas, they are relying on an in development indigenous radar in the Mk2 and AMCA to give multifunction radar ability), and updates to avionics.

Tejas Mk1 had two versions, the first 20 were IOC standard, second 20 were FOC standard which introduced aerial refuelling and some airframe box lightening to allow closer to official payload capacity.
 
Also, MAWS was originally in scope for Mk 1A but has been kicked down the road to Mk 2, which was to be unveiled in 2022 but is now tentatively 2026. And so it continues...

Much of the ancillary 1A work involves redesigning avionics and systems in a more logical and maintainable manner.

Unfortunately ordering them in penny-packet quantities contradicts the whole purpose of developing a light fighter which could be bought en masse. When they have more than twice as many Flankers as they will have Tejas, what's the point?

The point is that once all the Mig-21s are gone it is not economical to fill the gaps with flankers/Rafales.

But then the orders should be refelecting that replacement. Maybe not 1:1 per say but something like 1:2. Mk.2 also seems like a waste of resources. What will it offer over other types in service other than being a slightly bigger Tejas Mk.1? Rather take a step wise approach with AMCA like KF-21 and make Tejas Mk.1A the definitive version.
 
What do you mean that the israeli radar doesnt have multifunction capabilities? Are you saying it lacks air to ground capacity or certain air to air modes? I tried looking this up and could not find anything.
 
In Indian implementation it operates in either air to air, air to ground, or air to sea modes, they purchased the emitter but use their own indigenous signal processor but it cannot simultaneously operate in multiple modes like it does in Israeli or Chinese service (i.e. if your scanning the ground your blind to the sky and vice versa)

The thing was, mk.2 was a much modest aircraft with *only* a new engine and a slightly enlarged airframe. Mostly the same planform as well, and was supposed to be a beefed up version of what the mk.1a is today. Unfortunately for the IAF, the MMRCA programme ended up being a complete joke of a project and the gov. officially announced that "Tejas" would replace MMRCA. That Tejas is the new mk.2.

Is that a sound choice? Well, I don't think it is and really agree with you ok that front, but we have no say in what Indians want.

Funnily enough, since then they've also shelved FGFA, and MMRCA was revived another way.
 
The expansion of Tejas orders is also to fill the gap between the Mk.1 and AMCA which has widened over the last few years when the AMCA kicked off in 2010 it was expected to have a first flight around 2018 and enter service around 2020, jump ahead to four years ago and it was to first fly in 2026 enter service in 2029, but now its not expected to enter serial production until 2029 and enter service until at least 2032.

So initially the Tejas was supposed to be the 2010's fighter to tide them over until the 2020's AMCA, but now AMCA is a 2030's fighter and Tejas has to last in production until then.

sounds quite a bit like Dassault, France and Rafale. It keeps Dassault busy and running to keep the people employed an capabilities going until FCAS arrives.
 
Mk 1A deliveries now delayed by another four months due to unavailability of a 'critical' European component, or by IAF change requests, depending who you believe.
