Are we going to use F414-EPE which Offers up to a 20 percent thrust boost, increasing it to 26,400 pounds (120 kN), giving an almost 11:1 thrust/weight ratio?

And why increase of weight will not effect her maneuverability? Btw i do think tejas mk1a is a very unstable aircraft. I hope mk-2 doesn't become a flying duck like F-16.
Mk1a will have auxiliary intake......
Just to increase engine performance in low speed


Sir higher thrust engine will also consume more fuel
..and the combat rasiur and ferry range will decedecr

Ok, got your point.
Centreline EFT can be problematic if you intend to return & land with it. Why not die strike missions then? I have regular listen Rafale & F-18 with one...

But always why keep the centreline pylon empty!?!?!! Why isn't this one carrying one extra LGB or a BVR?? They're comparatively much lighter.View attachment 39033 there is literally only 2 images of Tejas utilising ALL it's pylons. This;View attachment 39034& this;View attachment 39038
Going for CAS, could carry another of those in the centre.View attachment 39035...or with a central tank (and/or 2 outer-wing tanks), 4 of those in tandem on each wing. It actually can!View attachment 39037View attachment 39039

Mig-21/29, Mirage-2000s are yesterday's aircrafts with 4 AAMs... Gripen as you say has atleast 6-7 & that's what Tejas should too.
Bdw that ldp pod station can carry a missile which not rail lunched....
Like mica ir...iaf thinks so...

Previously designed supersonic tank was for 450 ltr ...now it is designed to carry more fuel

and what made you think Mk1 doesn't have those?

2. Not all Tejas will carry LDP only couple during a mission and not all Tejas will have same configuration some for A2A some mixed or only land attack. Missions are not done alone but in a group so each a/c are configured for role designated for it. Only good thing is that being a modern omnirole a/c any SP can be configured for any role no special modifications needed.

Please stop copying posting BRF post here. If you are so fixated joing BRF.

I've often seen Tejas carrying Derby without its front fins, like the above photo.. why is that?
View attachment 38995And what happened to Python-5?

Also, carrying only 4 AAMs isn't impressive at all. That's Mig-21 standard. Why does Tejas IAF almost never carries any centreline drop-tank leaves that hardpoint empty? (Btw was this real or mockup?) View attachment 39001 ...Instead it could carry 2 (or in future, more) extra BVR missiles on that strong pylon, like this LCA Navy display from AI17. View attachment 39003
Never saw the middel one with Army camo. Looks gaudy though.

Anyway, thats either early model of Astra or R77 certainly not Derby - the middle one.

Tejas Navy though :drool:

So...... you are saying on clean frame T/W ratio is optimum.
And also will this not turn into another f-16 which is fantastic fighting plane(although my favorite is mig-29) and not mirage 2000 which IAF liked always?
Sir, regarding IAF I can't say any definite thing.
Maybe in future they can say we have to replace the engine. (it happens with every aircraft but in IAF case it happens way early maybe this time it will not because of now less development time thanks to tejas mk-1 development )
But if the above point is true then I can't help but think SOME PARTICULAR ENGINE PART-2 is on the cards for our tejas mk-2 .
What I can say is that thrust to weight ratio of a fighter plane with decent amount AAMs must and should be above one.
Are we going to use F414-EPE for mk2 which Offers up to a 20 percent thrust boost, increasing it to 26,400 pounds (120 kN), giving an almost 11:1 thrust/weight ratio?

And why increase of weight will not effect her maneuverability? Btw i do think tejas mk1a is a very unstable aircraft. I hope mk-2 doesn't become a flying duck like F-16.
""MWF has significant L/D improvements throughtout the envelop. Inspite of lower TWR, it will have better transonic acceleration, top speed and STR. The details were in the report that Jay and I wrote.

Obviously, at MTOW, it becomes a bomb truck, just like Gripen E And Rafale. Their TWRs are around 0.6. I don't know where this becomes useful in the Indian context. Our fighter bases are close to the borders. The enemy sits right across the border with good radar coverage. We don't have a France bombing Libya kind of scenario. Also although it may be possible to arm MWF with two Brahmos or two Scalps and two big DTs, it is highly unlikely."

Sir I quote them bcoz I have zero knowledge.......

Please.. don't scold me.....
At MTOW it will definitely be a bomb-truck and fly like a 747, same for any multirole fighter going for strike mission. It'll depend on BVRs & will have to jettison the payload if drawn into a WVR dog-fight. But not so anymore after it has lost that extra weight.

Because empty weight of MWF is very close to empty weight of older Mark2 (will call that from now onwards), clean configuration thrust-to-weight ratio for both will be very similar if both are carrying same fuel, while MWF will still turn better due to its canards.
Same if both would carry equal payload of weapons... But MWF can carry more both fuel & armament, that increases its range & teeth. Ideally it will burn that extra fuel & shoot those extra BVRs before getting into WVR with optimum T/W, equal to old Mark2.

If it gets F414-EPE engine then it's performance will increase even more... Or will it get Safranised-Kaveri? I don't know. Confusing.

I think with Tejas specifically it is more to do with the fact that so few are in actual sqd service so you rarely see pics of what is going on in Sulur but rather what is being done by HAL for test air frames or for air shows.

Once the bird reaches broader use by the user, you will start seeing a more regular expression of everyday use configuration.

^^ Their heli transport fleet are completly license production and fighters are either blatant copy or stolen tech having said that their industrial prowess is second to none/

By hook or by crook they have created a complete military - industrial complex from nothing in 30 years. Whatever else my opinion about the CCP I do respect their resolve to see things in strategic perspective. Nothing gets in the way of their ambition.

India and its political ecosystem still have a long way to go.

You sure it's 120 kn and not 110- 115 max around.

Mig-21Bis fleet to continue on for 5 more years in IAF

idrw.org .Read more at India No 1 Defence News Website http://idrw.org/mig-21bis-fleet-to-solder-on-for-5-more-years-in-iaf/#more-211548 .
IAF has no problem to operate Mig-21 for another 5 years but can't order more Tejas mk1 with FOC. there will be a gap between mk1 and MK1a ( 2021 to 2023 ). Do IAF really believes these obsolete Mig-21 have any significance in war scenario??
If, Yes then Tejas will have twice significance then Mig-21
If, No then why they are hell bend to operate these non-reliable planes. Order more Tejas and retire Mig -21
Tejas manufacturing is slow because of timelines are given by IAF in that way. HAL has to deliver 24 aircraft till Tejas mk1a inducted in 2023 so no point ramp up production of Tejas for now
IAF wants to operate Mig-21 only to make excuse to buy foreign maal so whenever Mig-21 will crash our chief will cry and say nobody even uses a car that much

Again, lack of basic knowledge is displayed by you.
Mk1A is from 2023 is not a "gap" but a "delay" caused by HAL's delay in responding to IAF's queries on the RFP and on price finalization. IAF wanted Mk1A as soon as possible. In fact IAF themselves complained to MOD against lacklustre attitude shown by HAL on this issue.

If Mk1A is delayed because of HAL, it is unfair to ask IAF to order more Mk1.

Also, suggesting to order more Mk1 just because of obsolete Migs is laughable. IAF doesn't want light fighters anymore. It wants only medium weight and heavies. So why would they order more Mk1s and encumber themselves with more light fighters for next 40 years? Makes no sense.
