Looks close but arent 2 tejas going to be delivered in march 2014 so going by the table we are ahead of schedule and the production rate doesnt increase till 2025 which is hard to believe.

Depends if that table is correct, official statements said, the first 4 MK1 will be available this year and the figures for MK2 seems to be too streched too. The first flight might take time, the flight testing and production however should be faster, since there are not that many external changes planed so far.

I read somewhere that the over all layout is much the same just slightly elongated obsolescent parts dropped and replaced.The flight testing and the production can continue with the current avionics,the engine option is clear so there is no reason it will take till 2025 for the first mk2 sqd to be commissioned.

Is this a Tejas thread or semi-nude picture thread? Folks.. keep it clean.

SP-1 and SP-2 go to the testing establishment. SP-3 and SP-4 which are scheduled to be delivered by the end of March 2015 are the first two SP planes heading to No. 45 Flying Daggers. By April 2015 IAF is scheduled to have 2 operational Tejas Mk 1 planes.

External changes will be, the modified fuselage and extended airframe, because of more space required for engine, fuel tanks and avionics. not a big deal that would require much testing, what we don't know yet is, if IRST and AESA will be availabe from the start or would come later only. In both cases however, the flight tests should be done way earlier with MK2 prototypes and should not require that much of testing, UNLESS we don't test the fighter but the immature AESA radar. Which as I often say, could be avoided by inducting MK2 with a common radar of MMRCA, that would be licence produced in India anyway.

The girl on right ruined Gripen's wonderful pic I was trying to look at the landing gear but she is blocking the view with her jacket! The Flanker is heavy one as usual..

Express News Service
Bangalore: The Aeronautical Development Agency (ADA) is giving the final touches to the preliminary design of the Light Combat Aircraft (LCA) Tejas Mk-II, scheduled to be completed by the end of March. An official confirmed to Express on Saturday that the detailed design phase of LCA Mk-2 would begin in the second quarter of 2014. A separate project team from ADA and Hindustan Aeronautics Ltd (HAL), dedicated to the upgraded version, is currently undertaking daily reviews to get the first cut of the design out by next month.
The main scope of Tejas Mk-2 programme is to have the engine changed from the current GE F-404 to GE F-414. A development contract for eight engines for the preliminary design phase has already been signed with GE, with the critical design review already been completed at its Boston facility. The Mk-II fighter will have OBOGS (Onboard Oxygen Generating System), which is being developed by Defence Bioengineering and Electromedical Laboratory (DEBEL), a Bangalore-based Defence Research and Development Organisation lab. "Currently, the ground development is over for OBOGS and the systems are undergoing various stages of qualification process," an official who wished not to be named, said.
Tejas Mk-II will have a unified electronic warfare system aimed at detecting and ducking enemy radar and later jamming it. "It is likely to be the most maintenance-friendly aircraft in its class and all equipment onboard can be easily removed or re-installed smoothly. The Tejas MK-I has some scope for improving the maintenance aspects, which is being addressed in Mk-II," the official said.
Her promises to make Tejas Mk-II free from any kind of dead weight. "The Mk-I has some dead weight in the form of lead plates installed to balance the aircraft which will disappear in Mk-II. It will also have considerable amount of extra fuel capability in operational clean configuration," he added.
The point performance of Mk-II will be higher than Mk-I, which means the aircraft will have better rate of climb, transonic acceleration and turn rates. The new version will have an in-flight refueling system and the ADA-HAL combine is planning to take a new route for Mk-II production. "We are going for the DFMA (Design for Manufacturing and Assembly) technique for the production of Mk-II. The DFMA concept will be used for the first time for an Indian aviation programme, which will decrease the production time and cost, also increase the quality quotient," the official said.
With the avionics systems changing at a faster rate leading to technology obsolescence, the makers of Tejas have an uphill task of making the fighter contemporary even in the 2025s. "We will straight away get on to the production phase after the prototypes complete the required test flights. The The Indian Air Force (IAF) support is a huge factor for the Mk-2 project with some cost being shared by them. It shows the confidence the user has in us. Tejas will be the mainstay for IAF in the long run," he said.
The Mk-II project was sanctioned in 2009 at a cost about of Rs 2400 crore and post-design finalisation phase, two prototypes are set to roll out from the HAL hangars. The IAF has committed a minimum of squadrons of Tejas Mk-2.

Tejas Mk-II Preliminary Design to be Out Next Month

ADA/ HAL are they really working for aviation/ aircraft industry?
Isn't it mandatory for all programs in aircraft design and manufacturing?

Every tom, Dick , Harry is (even for low value consumer items) using DFMA for new product and our babus just woke up as if they are talking about something revolutionary.

More I read more skeptical I get!

LCA Tejas: An Indian Fighter – With Foreign Help

Latest Update:

Feb 12/14: Costs. India’s MoD releases another set of official cost figures for the program, leaving out the Kaveri engine but adding a “Phase-III” development period. LCA development costs have now risen from an original INR 71.16 billion to INR 140.33 billion (+97.2%), or INR 168.72 billion (+137.1%) if one properly counts the Kaveri engine. Expected production line investments would push those figures even higher. India’s MoD was savvy enough to compare development costs to Saab’s more advanced Gripen NG:

“Developmental cost of Light Combat Aircraft (LCA), Tejas is Rs.7965.56 Crore ($1.09 Billion) including building of 15 aircraft and creation of infrastructure for production of 08 aircraft per annum. This compares with the developmental cost of JAS 39 NG Grippen is $1.80 Billion for developing 5 Proto Vehicles.”

That’s actually just the current predicted cost of the IAF’s MK.I/II development, minus the Kaveri engine, and arguably without creating infrastructure that could actually deliver 8 aircraft per year. The Gripen NG figure would need to be checked carefully, to see what it included and excluded. Even so, the simple act of making the comparison shows a greater sense of external awareness than we’re used to seeing from India’s MoD. Source: India MoD/ PIB, “Developmental Cost of LCA Project”.

LCA Tejas: An Indian Fighter – With Foreign Help

Latest Update:

Feb 10/14: A written reply from Minister of State for Defence Shri Jitendra Singh to Lok Sabha parliamentarians triggers stories about the IAF raising their planned LCA buys from 200 to 300. Unfortunately for the media reporting that story, it rests entirely on an error of logic. Here’s the exact quote, which can’t be linked anymore thanks to MoD web site changes:

“The MiG-21 and MiG-27 aircrafts of the IAF have already been upgraded and currently equip 14 combat squadrons. These aircraft, however, are planned for being phased out over the next few years and will be replaced by the LCA. Steps have been initiated for upgradation of other fighter aircrafts like MiG-29, Jaguar, Mirage-2000; transport aircraft like AN-32 and Mi-17/Mi-17 IV helicopters.”

What this statement does not say is that the replacement will happen on an equal basis. It’s perfectly possible to replace existing squadrons with fewer squadrons and fewer planes, if one is so inclined. The Americans have been doing so for decades, and they’re hardly alone. So far, firm IAF commitments involve 126 LCA Tejas planes: 6 squadrons of 21 planes each, with only 96 (16 x 6) as front-line fighters. Each squadron also has 3 rotation aircraft to cover maintenance absences or loss replacement, and 2 twin-seat trainers, to make 21. Beyond those 2 Tejas Mk.I squadrons and 4 Tejas Mk.II squadrons, we’ll have to see.

One Innocent question... What about infrastructure and skill set.. Did Grippen start from "0"? Sweden had no experts? Is Grippen Sweden's first Fighter plane?

Does Sweden has experience of making fighter planes?

He doesn't stated any opinion, just posted news and please not these excuses again. We had no experience great, then we should have done the development with a foreign partner and consultations from the start, not only when our own tries didn't worked out. The fact is, that even an experienced country like Sweden and an experienced manufacturer like Saab took design support of BAE, took a proven foreign engine from GE and modified it to their own requirements, added available foreign avionics and systems...all to ease the development and reduce risks!
That basically is the same approach that we used with the Dhruv too and today the Gripen and the Dhruv are successful. So there were better ways to do the development of LCA, either based on foreign examples, or even on own examples, but we simply messed it up and we shouldn't keep denying that!
