LCA TEJAS MK1 & MK1A: News and Discussion

[Tridev123]

Oh, no. Tejas Mark2 does not exist anymore.

MWF is to get new name. They even received suggestions via twitter.

It's father is the Tejas. It's basically a stretched version of the Tejas with canard. Whereas the Amca, Tedbf and Orca are twin engined and very different from the baseline Tejas.

it wont 200 if engine is not desi....

Says who?.. No plans for desi engine in any of the MWF, atleast not until 2030 (maybe after that).

tech demonstrator or first few batches may have american.....

mirage 4000 was further developed into new bird with new name......rafale.....similarly yes tejas is daddy

MWF has more design refinements than that... Then ORCA too is same sort of extention from LCA to MWF to TEDBF (only AMCA is completely independent design, Rafale was too).
Can't forever keep calling it "Tejas" nor make calculations based on assumption that it is only Mig-21's replacement.

123 Mark1/A will fill in the gap of some retiring Bisons, but rest will be along with Mig-27 and Jaguar's are to be replaced by 200 MWF... ORCA to take over from Mirage-2000 and Mig-29UPG post 2035.

• MWF is to have F414, all of them... that's official (maybe MLU reengined to K10).
• AMCA officially announced will have F414 powered Mark1 (from 2030) and K10 powered Mark2 (post 2035).
• ORCA/TEDBF hasn't got anything declared, but if it is inducted between 2030-35, then several squadrons may fly with F414.

So 123 single F404 jets... 200 single F414 jets... 100-250 twin F414 jets... NOW do the math.

 

[Kchontha]

Why don't we design a Jagour like aircraft with smaller twin engine that can be doable? Do we ignore that idea? Tejas cannot be called truly indigenous because of its powerplant being foreign. Kaberi was suppose to replace f404 in its production variants but unfortunately it could not fructify. At the same time MWF and tedbf/orca are design based on f414 as their primary powerplant. It's ok and doable since their engine is proven one. But in case of amca the matter won't be the same since amca demonstrators or initial aircrafts will fly with f414 but will be replace by a 110kn class engine. But the question is can drdo/gtre be able or have the expertise to produce an engine of this class with simmilar weight and size as that of f414 which produces 98kn only at the moment. Or do they done feasibility home works on that front. I don't think so like as in case of Tejas. In the end our amca may be underpower or do we have to rely on ever unreliable American for an enhance verson of f414 or is it better to put another engine option which produces 110 kn. I wonder!?

No requirement. That would be a solely Ground Attack jet (era of twin engine light fighters is gone) . Even rengining Jaguars with version of Kaveri is unlikely.

This is the latest possibility as of now, let's see what happens.

Fighter jets: After France, now UK pitches for joint development of future fighter jet engine - The Economic Times

Making a pitch for the ambitious Indian plan to achieve self reliance when it comes to combat engines – a key technology area that only top defence production nations have expertise in – the UK has said that the two countries are `natural partners. The offer comes even as Safran has said that...

Wish to point out a few things. As you have yourself admitted the design of the Tedbf and Orca is pure speculation. No frozen design is existing for the two. The final design may well turn out to be a surprise without even a delta wing you configuration. Let's not see them as extensions of Tejas at the present time. The design of the MWF on the other hand is frozen (almost 100%)and descriptions of the MWF by ADA etc start by stating that it is more than a metre elongated Tejas. If you would post official documents released by the design centers at various forums including the Dec Expo you will see frequent references to the Tejas.
Please let's not argue for arguments sake.
If you dispute my assertion please quote official documents stating that the MWF is a clean slate design.

The other point is that the replacement for the Mirage 2000 is the MWF and not the Orca. The Orca if it at all materialises is in the class of the Rafale. The maximum take off weight and payload capacity of the MWF is very close to the Mirage 2000.
Both are single engine planes.. Please go through interviews given by the Air Force Chief where he has mentioned that the MWF is a Mirage 2000 class aircraft. The Air force is so much in love with the Mirage that it wanted an equivalent replacement albeit better in some areas.

I fully agree that the AMCA is a completely new design influenced by the F22 Raptor. Most 5th generation planes borrow heavily from the F22.

I hope that ADA, NAL and HAL can deliver the MWF within 5 years. But intuition tells me that it won't be available till almost a decade. The past reputation of our aerospace entities fosters pessimism.

I myself once wondered that they might find it easier to create ORCA by modifying F414 AMCA's rear fuselage with Tejas like delta-wings and canards... So yes, that is not impossible.

But these replacements are not going to be classwise, but by requirement and timeline.

Hundreds of Mig-21 are being replaced by as few as 123 Mark1A.
Hundreds of ground attacks have been/are being retired, to be replaced with light-medium weight MWF by 2030 and heavy-medium MMRCA.
After 2030, AMCA and ORCA will be replacing some older Su-30 too.

Any news on the metal cutting for the MWF. At least one prototype fitted with GE414 engine should have been ready by now (in the ideal world) doing ground runs. The Chinese plan to deliver J10 to PAF. Our MWF is supposed to be ready in time and outperform the J10. It is our answer to the J10. God alone knows when it will be available. We took 10 years to progress from IOC Tejas to FOC Tejas. Validating various aspects of the MWF will take time and will not be so easy.

Dunno
But he was doing great work in promoting tejas aircraft.

 

[Assassin 2.0]

11 May 2004 was Technology Day. To mark this event, all the three Tejas test aircraft, TD1, TD2 and PV1 flew together for the first time. The Pilots flying the aircraft were Gp Capt RKS Bhaduria, Wg Cdr Vikram Singh and Sqn Ldr Suneeth Krishna.

Friends small update regarding Harsh Vardhan sir.

 

[Kchontha]

A swarm of mk1a and a few surkis will be enough for porkies front while MWF, few rafales, orca and amca should be kept for the chinkies. At the same time we need to increase the presence of awac n netras in the sky. At the same time Our vbraam capabilities should be kept superior to adversaries.

 

[patriots]

Bdw
Don't be surprised if Tejas shots down
Or gets shot down
If the cap from both side become s a skirmish
