Hope a "recent" light fighter to be better than a 1960 one!!!
What? Are you high on weed or whut?
Which 1960 fighter could fire bvraam ,helmet mounted display, fully digital display, fully flybywire system( all axis), can sustain more than 8.5g
And can be integrated with data links?
If you can't contribute any thing here then better STFU.
And don't degrade yr self to stupid

I think be meant, he hopes Tejas ("recent" light fighter) to be better than the Mig-21 (1960s one).

I didn't know our Mig-21Bisons had full flybywire...

Variable cycle? That is a joke. The american is struggling to get their variable cycle engine (the real one) ready for their future 6th generation fighter, Indian had decided to equip their LCA with such an advanced engine 30 years ago?
Such a low bypass engine with only 5 stage compression really require a great efficient core. Certainly it was a highly ambitious design by the capability of that time. I think they should have designed a twin engine Tejas and should have gone for something like HTFE 25 in making right now. When you plan something so ambitious, than you develop some state of art technologies but not the end product. DRDO developed many technologies but stuck in Sigle crystal blade. Look at HTFE 25. It is almost half of the power of GE 404 with only 350 lg weight. Imagine had we developed HTFE like engine with thrust of 50 KN dry and some 85 KN wet (2 engine) than we would have TEJAS operational in twine engine configuration. Now better we operationalize Kaveri as soon as possible with some 60 KN dry and 100 KN afterburner to end our dependence on US or any other country.

That make people wonder the real capability of DRDO to design an engine. If they have trouble of SCB, then they should modify their design by using other not so advanced material, like Russian and Chinese did. They shouldn't hold a project more than 10 years for 1 single material issue.

Every engine takes at least 10 years to make. India simply did not give 10 years to DRDO and kept changing specifications. In 2006, the Kaveri engine was asked to be similar to F414 and specifications were upgraded from that of F404. So, such practice has kept engine development at bay.

But it will be developed soon as this time the specifications have been clear

That is BS, the Kaveri project was approved in the late of 1980s, so it was already more than 16 years time until 2006 but not a single plane was powered by Kaveri at the time.

Stop being a retard. The first fund sanctions was in 1989. But that time India used it to make a turbojet engine. Only after 1995 Kaveri engine with 52/78kN thrust (F404 type) was started.

Yes, the start date is not until money is appropriated for the project.

That is a funny excuse.
Firstly, who decided to use Kaveri money for other project? DRDO, India gov or IAF?
Secondly, where is that a turbojet engine? How many were produced? If this engine was so important that someone had to steal money from Kaveri to support it, why it was not mass produced?
Thirdly, if DRDO couldn't start Kaveri project before this turbojet engine finished (did it finish?), why they apply for extra money and time for the turbojet engine?
Lastly, from 1995 to 2006, it was more than 10 years.

Only fanboy who know nothing about project management will believe this kind of story.

GTRE is not collaborating with Safran. None except Russia will ever give any technology to India as critical as jet engine. Safran has refused to give technology transfer. France will give TOT only for smaller technology.

Also, the MWF &AMCA will need 110kN engine which is under development. It will be K10 engine which will power the two aircraft

What JV does UEC Saturn have with GTRE?

Russia gave TOT of Su30, not JV. In 1996 India funded Russia to develop Su30 as Russia was reelore under severe debt and conditions imposed by foreign lenders. So, Russia agreed to give TOT as return payment and hence India got full TOT. Russia was whole hearted and have TOT of everything including engine instead of giving just the design.

I am not aware of this ToT that you speak of. If Russia is working with GTRE as an offset to a contract they are required by law to form a JV just as they did with HAL for airframe fabrication.

Russia gave direct TOT after being developed in Russia itself. Russia gave the technology in phases in an agreement with HAL. Unlike JV, the TOT is one time with HAL. In JV, profit has to be shared for prolonged duration.

Do you have any evidence of this engine technology transfer that bypassed the law requiring the formation of a JV?
