Tejas crossed 8G tests, they now want it to be 9G
Wrong. Infact they redued that from 9g to 8 g. They have agreed to Mk1+ specification which is 8g. However tejas did 8g+ this mean may be around 8.5 g which is comparable to gripen. If tejas does 26* AOA and complete tight turn in 20 second than I think the specification in this area are met. Now it will leg in climb rate and speed and acceleration. If aerodynamic changes are done as proposed and drag is reduced, there will be giant lap in the performance. It will come very close to the specifications of Airforce.

In place of giving your personal opinion and your impression, provide facts from reliable sources. We are ready to accept. Your post without facts and references is a BS.
So If I State that ADA and Not HAL was developing was developing LCA. I have to Come out with actual Award Document by MoD to ADA for reference ?
If I say that In the 1995 AESA Radars were First Operationalised in Combat roles That would be Heresay because I Wold Need to Put up a Deployment manifesto of JSDF here ?

So Because of this the Battle Field Didn't Change because i Have to provide Documentary evidence of the New Technologies that are operationally deployed today and Which were not Originaaly envisioned in LCA. ? you think its my impression. and because of that the post is BS.

Didn't know you had do a PhD on postings. Thank you for your enlightenment.

What do you mean wrong? Here is a message from a gentleman who flies the Tejas, I reckon

Regarding airframe certification of LCA, To be rated for 9G limits the airframe must withstand 33% higher loads. So for 9G rating the LCA airframe must not have failure of any componant of the airframe below 12G loads. 13G load was the breakup point load when some part of airframe gave way under stress. So LCA is now cleared for+9G loads. The static testing is a way to stress the airframe to make it break apart. The loading is countnuously increased til it breaks. It is also the break up loads.
IAF had initially wanted only +8g load, than they increased it to +9g, that involved further strengthening of airframe and so increased the weight of the LCA. The increased weight + higher G load needed higher thrust so the F404-IN20 (F404 version for INdia with 20K thrust)too became under powered.
ADA and HAL wud have delivered this ac long long back had it not been for the officers of IAF who on instructions from MOD have changed the specs many times in their effort to kill this project. The Specs for MK2 have now been fixed not bcoz of IAF but bcoz of IN who have now taken a Pivot position on the development of this aircraft.

See, I never talked of ADA or HAL anywhere. These all are your fiction of imagination and you are posting here with a context which only you know that. All of your posting have no context with what I say.

I think these are old news when the Tejas was planned for 9g. The specifications subsequently reduced to 8g. Tejas will have to show 10 g capability for 8g certifications if i am not wrong. Pl look at the specifications from HAL Website.

That Gentleman is talking like PDF fellows, doesn't know who was developing the bird.


A. LCA was Being Developed by Scientists at ADA, not by Engineers at HAL. Had it been the case LCA would have already been inducted but it would have some serious Draw backs.
B. It was transferred into production by HAL about 6 years ago. Which then operationalized the Bird.
C. HAd LCA still been with ADA we would See two TDs flying around with no hard-points.
D. The Battle requirements of today were not even Envisioned in 1990's so the changing of parameters was just essential it was not IAF but the battle field that Changed, a 3rd Gen Fighter would have been fine in 1990s today we need a 4.5 one.
E. Quit running Down IAF they are certainly more qualified than anyone on this forum about fighter jets, and by your standards you are accusing them of sedition!
Show me where in my post did I say a specific company? I said Indian designers and Engineers are being taken for a ride by the people in IAF and MoD. Also, please read all the 500 + pages, before you say only once has the IAF changed its specs. Read the quote in my previous message and follow Mr. Decklander's post to understand how Tejas was originally conceived, what changed, who changed and what caused the delay.

I am sorry, I will any day take the words of Mr. Decklander and Mr. Ersakthivel on Tejas than many in here, who just speak for the sake of making noise. Their discussions have always been on par with the reality and let them correct if I am wrong in saying that IAF is mainly responsible for changing their designs, simply to sabotage the project.

Hi guy pl ease look the specification I quoted from HAL website.

Thanks.

People you quoted are respectable members.

I have seen all those brochures, buddy. I have been following this project since 2002 and trying to read almost every development news on this project, sifting our facts from propaganda and fiction. What you see in the brochure is not what IAF is demanding/has demanded or will demand in the future. It is a brochure to show what HAL and ADA in collaboration with DRDO wishes to probably export to friendly nations. I would say HAL should agree to export Tejas even to Pakistan. Let Pakistanis fights our IAF with our Tejas and let IAF then learn the true power of Tejas. Call me whatever you want, but I am pissed off with the drama of IAF. HAL should care a damn about IAF and simply start selling the aircrafts to all foreign nations that are ready to test, pay and buy.

PAK FA is deal is almost dead. so don't fret over it.


Tejas is a Point defense weapon, not a deep Strike one. Different platforms for Different roles. LCA is not a Replacement for any other type of Aircraft.
We DO NOT need Rafale (100 mil+ $ per unit) for deep strike capabilities. Adding more Sukhoi Su 30 MKIs that cost nearly 60 million $ per unit are enough to do that.
http://vayu-sena.tripod.com/comparison-mirage2000-su30-1.html

Tejas MK1a with F404 IN20, Tejas MK2 with F414 EPE derived engine, AMCA and Sukhoi Su 30 MKI would make our IAF the one with finest inventory in the world.

Rafale is a SCAM to suck the blood of hardworking Indian tax payers by certain leeches in the IAF and defence lobby.

Are you joking? These volatile mortals in IAF wanted Tejas to be a replacement of MiG 21s. Initially, they wanted it for 6G+ and when Tejas crossed 8G tests, they now want it to be 9G which makes the designers change the material thickness and redesign. Same with the weight of the aircraft and the thrust demands. While Tejas has evolved into a 4.5 G state of art fighter, these jokers in IAF still set new demands, while they continue to have their orgasms with MiG 21s still. Who are they trying to fool? Blood boils when they spend millions to upgrade older aircrafts at costs that could buy more than 1 brand new Tejas MK1a. Whose money are they playing with? Do they think the tax payers in India have money tress in the back yards?
Correction, I meant initially they wanted it for 8G+ and NOT 6G+

Ok you can believe that but I think Pakistanis have hyped their JF blunder a lot in front of local audience. They do not want to humiliated.
Who is going to tell Porki citizens if Porkistan loses? Remember, this is the country whose history books teach that India used to be a part of Pakistan and Hindus created a separate India. They also tell that they won 1948, 1965, 1971 and 1999 war. They could claim that the JF won despite losing. Who is going to challenge them? I think something is going on regarding the Shia-Sunni rift, plus Modi pulled off a diplomatic coup with UAE and they promised to co-operate. Check the homepage of dawn.com, their COAS, PM are on a tour of Saudi, Iran some shit is cooking up, buddy.

Problem is you jokers lack any ability to understand any engineering efforts. CAG calculates the entire proportion of non indian raw material by value/LRU count, assigns it a proportion and then declares it non indigenous, more often the former than the latter. Typical bean counting behavior from accountants who don;t even understand the bare basics of technology.
If a mission computer is made using Intel chips and Hynix memory – both commercially available, then CAG says the computer is “imported”. Anyone with a modicum of intelligence or domain understanding would realize OTOH that ADAs note that its Indian is more accurate since putting those COTS items together into a functioning set up, with a local software program with multiple functions on top of a suitably modified RTOS is a non trivial, uniquely customized task and hence Indian.

CAG which can’t tell a screw from a screwdriver will harp on the “imported chip”, never mind that for every chip in the LCA to be locally produced would require India to set up a fab with a budget dwarfing the LCA ! No country assesses its local contribution the way the dunderheads at CAG and people like you do.

The Litening is trademarked to Rafael, its optics are from Carl Zeiss, its memory modules from Asia, its processors from worldwide suppliers – the entire IPR lies in stitching the entire item together & the imaging processing that makes it a leader. Of course, according to CAG it would be 80% imported.

Further CAG expects that indigenization would magically ensue even when low rate production without even confirmed orders for beyond 40 airframes at the time (and actually 20) would ensure local suppliers would not commit to investing in capex for such low order rates.

The Navy is facing much the same problem with its low build rates & perforce ends up having to import many items despite its relative success in indigenization.

Oh BTW, if you seek to rebut using that hoary, if I run out of missiles I will use my guns & hence STR is important – please don’t even bother. As things stand the CCM chosen for the LCA, the Python-5 with an IIR seeker is practically unjammable until laser based DIRCMs are introduced a decade from now on fighters. In the unlikely situation a LCA pilot sacrifices his long reach, Derby-ERs and then his CCMs his Python-5s, he is best advised to disengage, the same any true delta winged fighter unless he chooses to get into a STR based fight which would be silly. That’s pretty much the same lesson for the 7/7.5G JSF variants or the 7.5G F/A-18 or for that matter even the latest F-XX, because in close gun combat everyone dies at the same rate per multiple studies and an unknown/unseen opponent is often credited with the kill. No wonder then the IAF is insisting on a state of the art weapons fit on the LCA above and beyond what is on any of its fighters including the Su-30. The much vaunted F-22 even has to make do without HMS and Aim-9x, so much for comments about these painstaking integrations being mere add-ons. The LCA team is bending over backwards to accomodate everything the IAF needs. Meawnhile IAF is busy requesting Russia to even fix basic issues with existing items.

Also, as Saurav Jha pointed out few months ago: importance of IP cannot be overstated.

You can take even "70% imported" to 10 on your own time & will.

Think about the hassle we went to installing even a/c in t90ms.

People should understand above brigade officer level there are lot of chutiyas. An officer commanding 5000 men would have only 200 counterparts in IA. So it's only few dozen men at top who need to be 'corrupted'.

Obviously not all are but, it shows you. Even this 8 to 9g thing. Tejas is a sick aircraft, just the video at Aero India Bangalore last year, turns Nri khalistanis into patriots. What more to say?

Just to clarify on G-Limit for Tejas with reference of Reply from Facebook page - Structural simulation is done for 9 G, though not the aircraft as a whole.

So, its always possible, you will hear Tejas pulling 8.5+ G in coming days if not 9G. Just wait for it, it should be happening step wise step.

I put a question to Tejas - LCA team, btw anyone know how many SPs will be ready by March -2016 ? I know SP2 is almost ready and will be flying anytime soon.

After all, HAL need to make them in numbers as soon as possible.
