    From above MOD Figures the per unit production cost for each type made by HAL

    Su-30MKI Rs 326 crore per MKI
    Do-228 ~ Rs 77.85 crore per Do-228
    LCA Tejas Rs 135 crore for IOC & Rs 299 crore for FOC per Tejas
    ALH Rs 86.78 crore per ALH
    Cheetal Rs 20.3 crore per Cheetal
    A good part of that high cost for Tejas compared to the Su-30MKI are the costly western items. Same for every product.

    Does HAL public the final MK1A's specifications, especially the empty weight that saves 1,000kg from MK1 as the proposal?

    Tejas being accepted by IAF & going into full-scale production is a great feeling for me. First time in India we designed, developed, produced & operationalized a truly multi-role fighter. I fell excited every time I see a Tejas flying. Dr Kota Harinarayna on 17th TejasDay

    Dr.KH has aged a lot. He has to be there when the first LCA is inducted.

    yes indeed, he has aged. Such a polite and humble gentleman! For those who may not be aware, the LCA TD and LSP series were given the registration number starting with KH as a tribute to the efforts of Dr Kota Harinarayana to bringing the LCA program into being.

    the MK1A specifications have not yet been revealed fully. I guess we'll know exactly what it entails only after the contract signature with the IAF and MoD.

    Thank you BlackArcher. Hope they can trim some weights to make the MK1A better.

    PV-6 taking off for a sortie from Leh during hot and high altitude trials, 2016


    @ Kopyo-21

    The current LCA-MkI version uses 210 kilos with ballast in the nose to stabilize the aircraft. This will be removed, and the AESA and EW suite weighing about 250 kilos will be added. The net weight gain will be of about 50 kilos.

    http://www.indiastrategic.in/topstor...AESA_Radar.htm


    Bangalore. India’s Light Combat Aircraft (LCA) Tejas programme has been delayed indeed, but to make up for it, HAL is now working on developing a new variant, LCA-I P, which will be equipped with an advanced AESA Radar and an electro-optic Electronic Warfare (EW) sensor suite.


    The timeline for this variant has been set at 2017, two years from now. The AESA radar will be supplied by Israel’s ELTA Systems, a subsidiary of Israel Aerospace Industries (IAI). ELTA had earlier supplied its AEW&C (Airborne Early Warning & Control) system for IAF’s IL-76 based Intelligence and surveillance aircraft, designated by IAF as AWACS (Airborne Warning & Control Systems) aircraft.

    AESA, or Active Electronically Scanned Array radar, is the key component in the AWACS, enabling a 360 degree look-down-and-around capability to IAF for about 400 km. The aircraft is designed to guide combat fleets and ground assets in a war scenario. With no moving part, AESA is much faster in capability than earlier airborne radars in which rotodomes moved mechanically – and rather slowly – to scan different areas.

    AESA in fact was always in the LCA programme, and there were discussions with some foreign companies as well as with the state-run BEL in developing it. Finally the choice has gone to ELTA, which in any case has been collaborating with BEL. LCA also has a sophisticated fly by wire system and glass cockpit. Once the programme gets going, HAL may manufacture some 200 aircraft for IAF and perhaps another 100 for the Navy.

    AESA in the LCAs will obviously have a lower range, but it will be well integrated within the IAF network, and give a quantum technology jump to IAF’s combat capability. Notably, the 36 Rafales being acquired by IAF in the Government-to-Government deal will also have the AESA radar, developed by Thales.

    IAF’s AWACS aircraft – three delivered, two on order – are already integrated with its combat, transport and land assets and also networked with aircraft of the Indian Navy.

    HAL has in principle support from the Government, and is now working on the proposal with the IAF (Indian Air Force) in this regard. This variant will be developed on the existing LCA-MkI model, and will meet IAF’s requirements till the larger LCA Mk II is developed by 2021 with the more powerful GE 414 engine.

    HAL Chairman and Managing Director (CMD) T Suvarna Raju told India Strategic in an interview that HAL shared the technology concerns of the user – IAF – as well as the urgency for production of the aircraft in view of the falling numbers of IAF combat squadrons due to obsolescence. The AESA and EW suite will make the new LCA variant more advanced than the supersonic MiG 21s in capability, even though it will be a subsonic aircraft compared to the ageing aircraft of the Soviet vintage.

    A key technology being adopted now is 3D printing, which will cut design and production time by months. This is now being used for engines but it is being adopted for various aspects of aircraft design and production.

    P in the LCA-I P stands for prototype, but once accepted by IAF, it could be designated LCA-MkI-A or whatever.

    LCA-MkI, which achieved IOC-II (Initial Operational Capability, stage II) in January 2014 for acceptance by IAF as it is produced and tested, is yet to get the FOC (Final Operational Capability) but the focus now is on adding the EW package, originally planned for the LCA-MkII.

    The aircraft will continue to have the same GE 404 engine however in this variant, but the lack of adequate power will be compensated by the warfare capability generated by the new sensors, with AESA providing a formidable force multiplication. This type of radar uses multiple frequencies to electronically scan several targets simultaneously.

    The earlier radars used to have mechanically moving parts, whose output was painfully slow compared to the new generation electronic technology.

    Notably, US companies Raytheon and Northrop Grumman have an established lead in the AESA systems while in Europe, Thales has just about achieved it for installation on Rafale and Eurofighter aircraft. In fact, AESA was a key requirement for India’s MMRCA (Medium Multi Role Combat Aircraft) competition, and the 36 Rafale jets being acquired from France should have both the AESA as well as the Infra Red Search and Track (IRST) system.

    Israel is known for its excellence in electronic warfare systems, and ELTA should be able to meet IAF’s specific requirements.

    Notably, IAF is not happy with the GE 404 engine, regarding it as underpowered for warfare. But only 40 aircraft are slated for production with this engine. For LCA-MkII aircraft, there is an agreement for 99 GE 414 engines already with the US engine maker. The production of that aircraft is due to begin from 2021.



    The new LCA-MkI-P variant with the EW Package will also add some 50 kilos of more weight, but then, Mr Raju explained, the capability of the aircraft increases significantly, offsetting the disadvantage of a smaller engine.

    The current LCA-MkI version uses 210 kilos with ballast in the nose to stabilize the aircraft. This will be removed, and the AESA and EW suite weighing about 250 kilos will be added. The net weight gain will be of about 50 kilos.

    LCA-MkI and LCA-MkII are both single engine aircraft, hence the power of their engines to provide thrust to the aircraft and sustain their power-guzzling electric and electronic systems, particularly the radar, will always be critical.


    There are two naval versions also with high landing gear as technology demonstrators. The naval version has to be much stronger than air force aircraft as every landing on the limited space of a carrier is like a crash landing, and the aircraft has to be stopped by one of the three onboard arrestor wires which latches on to a hook in the tail of the aircraft. If the attempt fails by chance, then the aircraft has to take off again, and that is why its engine(s) are kept on full power.

    Mr Raju said that Defence Minister Manohar Parrikar was taking personal interest in the development of indigenous technologies and systems, including in the LCA, and HAL was working to speed up whatever it could do.

    For one thing, it is proposing now to take full charge of the LCA development programme to become the single responsible agency. Right now, the design and development of the aircraft, engines, weapons package etc, are with DRDO and its Aeronautical Development Agency (ADA).

    During a recent visit to HAL, this writer saw several young engineers, one of them trained in the UK. Like them, Mr Raju had joined HAL while young some 40 years back. He is as passionate now as he was perhaps then. He observed optimistically: We are taking steps in talent and technology to meet the timelines.

    There is an emphasis on composite materials, for which Indian companies, both in public and private sectors, need to do a lot. Significantly, about half of the LCA is made of composite materials, which are lighter but stronger than the aircraft grade aluminum.

    HAL has built seven LCA-MkI aircraft under LSP (Low Rate Series Production) and two under the SP (Series Production).

    Significantly, LCA has passed several crucial tests in operating from tough summer and mountainous terrains as well as in firing missiles.
    Let us all pray that HAL finalises the AESA and EW suite-Spj pod as early as possible so that work on the mk1A can begin in earnest. It would be too optimistic to ask for the first Mk1A prototype /LSP flight by the end of this year. If HAL can do it, it would be a first. HAL is scheduled to deliver SP-5 8 9 10 11 by the end of this fiscal.

    Some thoughts on LCA from http://idrw.org/the-desi-lca-is-defe...w/#more-158728

    It has been loved, hated, coveted, admonished and even ridiculed but for India’s homegrown combat aircraft, right now might just be the right time. The light combat aircraft (LCA) is the defence ministry’s lowest hanging fruit on the ‘Make in India’ path but it needs one final big push for which the government would need to step up soon.

    Two things stand in the way of the fighter fully taking off as a potent symbol of the Indian defence industry – a strange interference by the Defence Research and Development Organisation (DRDO) itself and a painful obsession of the air force to diversify its fleet even further with a new, foreign origin single-engine fighter.

    For a development programme that was sanctioned in 1983, the light fighter has come a long way. After limping its way through the 2000s, the single-engine jet has shown promise of late, maybe not as a cutting edge, globally competitive fighter but certainly as a platform that will enhance India’s combat capabilities within the region.
    Sum ergo cogito

    @ Arihant, HAL proposed that they would trim the weight in some where but mainly in landing gears that were over needed strong and over weight.

    Yes this is the case for N-LCA. The landing gear is over engineered and heavy and Ada plans to shave off some kgs by designing a new landing gear. Airbus was to be roped in as a consultant for this. This was the first time that Ada and HAL had ever designed a landing gear for a carrier borne aircraft and that is why they had increased the factor of safety and made the gear sturdier. As of now N-LCA weighs some 8200 + kgs empty. There is lot of scope for weight reduction for the Naval variant.

    This high empty weight means an even lesser weapons and fuel load. This coupled with a single engine and mediocre T/W ratio led the Navy to go for a new carrier borne fighter.

    And there is some good news. According to a poster at BR, SP-5 has cleared all taxi trials and will soon have its first flight.

    Its good to see that more and more desi journos and defense editors are vouching for and supporting the Tejas program. Earlier they were clamoring for the foreign single engine fighter.

    Kopyo-21, yes I've read on other defence forums that there are plans to reduce the weight and the figures quoted vary from 300 to 500 kgs, with 1000 kgs being the wildest, most optimistic figure. I believe a weight reduction of maybe 300 kgs might be seen, but until HAL releases the weight figures, we can't be sure.

    From Ananth Krishnan's Twitter feed. SP5, whose first flight was delayed due to some issue that was seen during ground runs, is now ready for its first flight, after completing its High Speed Taxi Test. SP7 should be handed over to the squadron soon. That would make its strength 6 SPs + 1 Tejas trainer (PV6).

    #TejasUpdate #7 | SP5 from the 2nd production facility of #HAL (erstwhile Kiran hangar) is ready to kiss the skies. It has completed HSTT & 1st flight likely this week. SP7 finishes contract flying and awaits a letter from #IAF HQ for customer flying.

    1st customer acceptance flight of SP-7 is over. SP-7 will soon join the ranks of Flying Daggers. No 18 Flying Bullets will most probably be the 2nd squadron to be equipped with Tejas.

    #TejasUpdate #8
    The first Customer Acceptance Flight of #Tejas SP-7 is over with No 45 Sqn #FlyingDaggers Co Grp Capt Madhav Rangachari taking the bird out on its official sortie. Couple of more flights and SP-7 will be part of the Sqn soon.

    Late night finishing touch for an early morning test flight by the technicians and supervisors, has been the story for Tejas. Right configuration, right kind of instrumentation, correct SOP, correct FCN, correct hardware/software combination and the correct flight test procedure have been the key elements of Tejas test flying, way different than a normal regular sortie. Data generation through well executed test points has been the main source to validate and improve the design.,
    The Lsp is carrying a Litening LDP. And SP-5 is supposed to have its first flight this week.

    Some news on SP-5 from BR.

    SP5 has turned out to be the trouble-child of first-time parents. In the latest HSTT, some oil leaks were reported. The aircraft has now been re-assigned to Line 1 for rectification.

    Line 1 is now delivering an aircraft in less than 2 months. The last one was delivered in middle of Dec. So middle of Feb will be a good approximation for the next one from Line 1. SP5 has been almost ready since last July/Aug. It is assumable that the next aircraft from line 2 must also be near ready now. But, it is understandable that they want to hold on to LSTTs/HSTTs till they find out what they were doing wrong with SP5.

    Some news on Tejas Mk1 from Saurabh Jha's twitter feed

    Tata Advanced Materials Limited under the quality assurance of NAL has already delivered 3 out of 7 centre fuselage parts for the HAL Tejas build programme up to unit number SP-18.
    NAL has also completed control law modifications for the FOC version of the Tejas Mk-1.

    I guess within 2018, Sq-45 will over out of Bangalore to Sulur. It might also get FoC before moving out but lets see.

    I am also interested, where second squadron will be created and designated to move?

    Yes, its very likely that once they reach 12 jets, which will be in 2018, they'll move to Sulur AFS. No.18 Squadron 'Flying Bullets' will be very likely the next one to receive Tejas fighters and they were previously based at Hasimara AFS, operating MiG-27MLs before being numberplated.

    But with 1 squadron of Rafales being based at Hasimara, it's likely that they'll be based somewhere up north, after spending a couple of years in Bangalore. Being in Bangalore helps in that the flying crew gets to use the simulator and the ground crew being co-located with HAL crews, get trained faster. After they are almost fully ops, they'll move out and the next squadron will move in and so on.

    No.45 Squadron "Flying Daggers". From that video that Ananth Krishna shot, there are 8 pilots and 4 technical officers in the squadron, and none below a Squadron Leader's rank. 3 Squadron Leaders, 4 Wing Commanders and 1 Group Captain comprise the pilot pool, and all with varied experience. MiG-21, Jaguar, MiG-29 and Mirage-2000 pilots, so pilots with experience on a variety of jets. I remember seeing Squadron Leader Kartikeya Singh in another video on MiG-21 operations.

    From Ananth Krishna's Twitter feed. This was a pic of Sqn Ldr Arjun Patel going on his first solo on the Tejas. Below is a quote from one of the pilots, Wing Cmdr Tolani

    Tejas is a designer’s marvel. The Test Pilots and the designers have brought in the best of all fleets across the world. It is an intelligent combination of the best systems in the world.

    What is the reason behind stationing the Flying Daggers in Sulur? The squadron could have been deployed in the North say in Srinagar or Awantipur where they could have performed QRA and air policing roles.

    No 18 Flying Bullets is most likely the second squadron to convert to Tejas. I have read about this in a number of places.

    Grp Capt Rangachari is a Mirage 2000 pilot. Wing Co Tolani is a seasoned MiG-29 guy. Squadron Ldr Kats is a Fighter strike leader. And Wing Co S Shankar aka Danny who is also the 2IC is a Fighter Combat leader.

    Black Archer, are you aware of the fighter stream to which Danny belongs? His brother, Dino who is also a Wing Co and a Cat A Qualified Flying Instructor is also posted to this squadron.

    Wing Cmdr Roy was from the Jaguar fleet, but not sure about either 'Danny' or 'Dino'. Didn't realise that they were the Dhankar brothers, kinda like the Keelor brothers, Denzil and Trevor, in the 1960s-70s

    I think the reasoning behind posting No.45 Squadron to Sulur was that the Southern Air Command was finally being given fighters. They've gotten Su-30MKIs at Thanjavur AFS and now Tejas at Sulur AFS. Proximity to HAL Bangalore is a big plus as the fleet is still being worked up and they will not yet have fully streamlined the spare parts ordering and stocking at other bases. But you'll see these guys detaching to various air bases up north and in the east, regularly. No.45 squadron has already seen detachments to the north for weapons trials and training. And soon they'll be participating in the IAF wide exercise.

    USAF Chief of Staff to fly Tejas

    Chief of United State Air Force will fly India's indeginously build Light Combat Aircraft Tejas on Saturday. This will be the first time, the head of a foreign military is flying Tejas and the move will somehow silence the critics of home grown fighter jet.

    General David L. Goldfein, chief of Staff of the US Air Force, who is on his visit to India, will take a sortie in LCA Tejas from Jodhpur Air Force station on Saturday morning. Goldfein along with General Terrence O'Shaughnessy, Commander of US Pacific Air Force, landed in New Delhi on Thursday to boost military ties between the two nations and already had several rounds of discussion with key functionaries of IAF, including Air Chief Marshal B.S. Dhano at Air Force headquarters.
    ..
    And apparently this is soon to be followed by the French Air Force Chief of Staff flying a Tejas twin seater on February 7th

    From Ananth Krishna's twitter feed

    #JustIn | After Singapore Defence Minister Ng Eng Hen, it could be the turn of Gen David L Goldfein, Chief of Staff of @usairforce to fly #Tejas anytime soon. Mil sources also confirm that French AF Chief too lined up for a sortie on #Tejas at Jodhpur on Feb 7.

    General David L Goldfein, Chief of Staff of the US Air Force, is on an official visit to India. He flew a sortie in LCA Tejas aircraft at AF Stn Jodhpur today on PV6.

    This is what I called Tejas diplomacy.



    Between Wing Co Roy of No 45 Winged Daggers is a TACDE instructor. Next time when someone says that the IAF isn't very keen on inducting Tejas and accepted it just because it was forced on them that had this been the case IAF wouldn't have posted some of the best Pilots in the business to this squadron. The airforce is upbeat about the Tejas, loves the Tejas and wants to exploit its full potential.

    After the USAF Chief of Staff, its the turn of the French Air Force Chief of Staff to fly onboard the Tejas twin seater.

    French Air Force Chief of Staff General Andre Lanata takes sortie on IAF Tejas



    JAIPUR: The Chief of the Staff of the French Air Force, General Andre Lanata, on Wednesday flew a sortie on the Indian Air Force's Light Combat Aircraft (LCA) 'Tejas' in western Rajasthan.
    The indigenously built aircraft took off from the Jodhpur Air Force Station. Lanata was in the rear seat of the twin- seat trainer aircraft, a defence spokesperson said.
