That was the initial goal, but with all the delays of the project, the future potential is getting lower as well. By now and with MMRCA as an alternative, 200 LCAs will be the max for IAF, which still is a good number, the problem is only, that we fail to do things simple like the Chinese can, we often want to much and make things too complicated again.
Take the MK2 for instance, we had weight and thrust issues, so instead of fixing these things only and induct the version with MMR as soon as possible, we now added fuel tanks, more avionics, IRST, possibly even a new radar and to make it even worse, also want a complete new cockpit. These changes obviously needs more time, with more vulnerability to new delays as well, which explains the hasitation to further orders.
However, I agree with you that IAF should have ordered and inducted the MK1s way earlier, since they are clearly more capable than many of the older Migs, but I think that has to do with the long and slow testing process of ADA/HAL as well.


I am in no way suggesting HAL is not at fault, but IAF needs be a little less stingy, show more confidence in HAL, and in other words be a little punjabi (if you know what i mean). IAF needs to chill, needs to make an order book of atleast 350 jet... so HAL can dedicate a seperate line for MK2, provide mk2 in three tranches. Accept the first tranche with MMR Passive radar, next tranche with better engine and AESA, and then keep developing it.

Sancho- I get that the LCA's delays in part can be explained by the IAF constantly changing their requirements. But this is fair enough surely in keeping with the IAF's philosophy of fighting quantity with quality. The IAF is not a force that seeks to put up sup-standard fighters with deficences made up by fielding them in huge numbers. This is a doctrinal issue.

Are they really and if so why? Many people say this because of the higher thrust engine, but without understanding the reasons. LCA turned out to be heavier and draggier than planned, that's why certain flight performance goals couldn't met. But to as a solution to meet these old goals, was a new engine. So they didn't changed it without any reasons, nor was it a new requirement from them, infact they were the only once that resisted to go for an engine co-development, at a time when even DRDO had no faith in Kaveri K9 anymore.
Similarly, ADA/DRDO promissed too much about the N-LCA and as IN already officially stated, these companies underestimated the changes and overestimated their capabilities, which is why IN, just like IAF requested corrections.

HAL gears up for first flight of Tejas LSP-8 | Tyagi says lines decked up for series production

Bangalore: The Indian Air Force's (IAF) long and frustrating wait to own the home-grown combat fighter might be finally over with the Limited Series Production (LSP-8) version of Tejas completing two crucial engine ground runs (EGR) successfully. An elated Hindustan Aeronautics Limited (HAL) chairman R K Tyagi told Express on Wednesday that his boys are working overtime to ensure that the LSP-8 hits the skies soon.
Battered by the media, bruised by IAF and butchered by desi aerospace gurus for unprecedented time and cost overruns, Team Tejas had to face the music from all quarters, for over a decade. Tyagi, who took over the reins of HAL last year, said that LSP-8 would make its maiden flight some time in February. “The aircraft is almost akin to the series production (SP) standard aircraft. We have upgraded the systems to incorporate the feedback from the ground/flight evaluation teams, who dealt with earlier LSP variants,” Tyagi said. It will be the 13th aircraft from the Tejas project flight-line to take to the skies, and along with LSP-7, the IAF pilots should soon begin their much-awaited user evaluation trials.
Two preliminary EGRs of LSP-8 have been completed so far for the first time by HAL personnel and certified by National Flight Test Centre. The aircraft is currently undergoing final system checks, to be followed by further inspections by certifying agencies. “Then we will have final ground runs, leading to low speed taxi trials (LSTT), high speed taxi trials (HSTT) and the actual first flight,” Tyagi said. “My team is really jubilant and we would soon commence the work on series production,” Tyagi added.
He said with most of the aircraft system performance reaching almost desired level of expectation, Team Tejas in HAL would now be able to concentrate on stabilizing the production line. “The production line of Tejas at HAL has been moved to a new premises with a built-up area of around 28,000 sqm of Hangars, engineering and administrative blocks. Upgrade and augmentation of production tooling, which is expected to be 2.5 times of prototype requirements, is underway to enhance the rate of production and to expedite delivery of the aircraft,” Tyagi said. HAL promises to add more teeth to IAF by delivering 2 Squadrons of Tejas in the next five years.

Hell no....are you dreaming? Our squadrons consists of 18 to 20 aircrafts basically...there are only 8 of these birds. These will be used by the IAF for the second IOC(whatever that bullcrap means) and the FOC. So the first squadron might be inducted two years later after the FOC if things go smoothly.

These aircrafts will now open their flight envelope fully and will be pushed to it's limits to see what it can do.

Astra BVR to be Integrated with Tejas aircraft by year end

Back from successful development trails of Astra Missile last month , Sources close to idrw.org have informed that Astra Bvraam will be integrated with Tejas aircraft by year end , but first test firing of the missile from an aircraft will likely take place in mid of this year from Sukhoi Su 30MKI .

The maximum range of Astra is 80 km in head-on chase and 20 km in tail chase. The missile could be launched from different altitudes – it can cover 80 km when launched from an altitude of 15 km, 44 km when fired from an altitude of eight km and 21 km when the altitude is sea-level . The missile can reportedly undertake 40 g turns close to sea level.

First test was carried out 10 years ago in 2003 but missile was more of a Technology Demonstrator then and many of the technology was yet to be developed . missile has lost lot of weight and new missile sensor had to be developed . Initially missile range was around 40km in head-on chase but advancement in missile technology over the years and development of the missile enabled it to achieve 80 km in head-on chase , Missile will find its way into Sukhoi Su-30MKI first and later in Tejas MK-1/MK-2, first test firing from Tejas might take place next year after series of in flight testings are carried out of the missile on-board aircraft.

Astra will also will be integrated with Mirage-2000 and Mig-29 in near future after missile hits production line most likely in 2015 . DRDO is also planning of more advance variant of Astra MK-2 with 110-120 km range in near future .

Conformal antennas are not new. It was always possible to make conformal arrays. Good news nevertheless.

Hindustan Aeronautics is ready to take on challenges: Tyagi

...1.India's Light Combat Aircraft (LCA) has been getting delayed, what is the latest update and what is happening with the naval version?

Ans:LCA is a prestigious national project in which HAL is the lead production agency and ADA is the lead designer. At present the design and production activities are going concurrently. However, HAL is geared up to commence delivery against the current order for LCA within three to six months of the aircraft certification (Initial Operation Clearance - IOC). We hope that ADA achieves IOC by the second quarter of 2013.

We have already initiated proactive action pertaining to tooling, assembly jigs and build requirements and we are in the process of streamlining various productionization activities which would lead to ramping up of production rate.

The maiden flight of the Naval variant of the Light Combat Aircraft (LCA), NP-1, was carried out successfully on April 27, 2012. Flight with undercarriage retraction was carried out on June 27, 2012. Presently the Naval LCA is being prepared for shore based testing facility trials...

...4.'What are your expansion plans for HAL?

...LCA production facilities will be augmented to increase the production up to 16 aircraft per year...

Astra will also will be integrated with Mirage-2000

That is idrw.org BS again, Mirage 2000s will get MICA as already announced, not to mention that Astra could be carried only at the inner wing stations, because of the size, which would be a major disadvantage for Mirage.

Not for India. This technology was developed during the RISAT program and has been transferred to private industry. Future fighter and missile programs will see use of conformal antenna arrays especially AMCA program.
