As given in Wikipedia it can be as high as USD124 million based on the variant. The estimated price is as on 2009. So, there are chances of it going even higher.

Wow ... Just pure awesomeness.. no one in their right mind would ever say no to a date with her.
Only 40 fighters
this is just not right its high time we need a movement on the scale of Jan Lokpal bill to shake things up in defence ministry and the armed forces. we just can keep emptying our forex reserves just to make sure we live up to the expectation of the west as a major arms buyer. Our Neighbour keeps on improving their defence industry by developing infrastructure in tune with their growth, but here we are hell bent on acquiring foreign equipments with a huge list of do's and dont's and end up becoming intellectually meek , this is just pathetic

If you had read the article given as a reference for that source, you would have understood how the figures had been inflated. Development cost per Rafale was going to be 60-70 million dollars, when the total number of orders were supposed to be 286. If Rafale deal goes through, the orders will cross at least 400, resulting in much lower costs per aircraft. Anyways, it is not fair to estimate the cost of Rafale based on that old source of 2009, when Rafale didn't even have AESA radar or hmd. Only way we can know the cost is when the deal is cut. Till then, we can only wait.

In one of the recent post of shiv aroor , he mentioned that IAF had "grudigingly" accepted tejas in 2011, and he will wait till 20 Dec 2013 to check the mood of the IAF camp.
Sometime in his post around 1 and half year ago he had highlighted that the radom of LCA was a generic problem that problem pushed the schedule by 8 months ( and which indeed happen ).
I was expecting a much vibrant coverage and appreciation of tejas in his blog, so I want to understand the skepticism in his post. Is it genuine ?
Though practically I feel , whatever Tejas has achieved, it deserves much better appreciation.
Also I feel setting up within a mere 28000 sq feet is relatively very small step to manufacture 20 aircrafts within 2 years. I thought there HAL could do better. The production line of TATA seems much bigger in comparison to what HAL has set up.
Between whats the status of the Kaveri. When will it be integrated with the pv tejas ?

How are we going to ensure that china does not get a copy of this design ( I hope the design is kept secret ), as they are master copy cats.

Here, about the radome issue.
ADA Wants You To Design A New Radome For The LCA Tejas - AA Me, IN
The chances of integration of Kaveri on Tejas are very bleak. It will, however be used in other projects such as AURA and amca.

Sure buddy,
Your point on economies of scale is very much valid. However, we need to take into consideration the inflation and the cost associated with addition of AESA radars and HMD as you said. These things are not going to bring down the price per aircraft. Since, we don't have any reliable numbers let us wait till the deal is cut.

Tarmak007 -- A bold blog on Indian defence: Pearls & Heroes of Tejas | Meet the all-women design team & shop floor rock stars of HAL | 'No dull moment working for India's pet fighter project'
By Anantha Krishnan M
Express News Service
Bangalore: "My father is 80 years old and he reads all the newspapers and updates me about the happenings around aviation. I leave home at 6 am every day and return by around 7 pm. Close to over two decades, life has been a great challenge dealing with some complex issues in aeronautics. Finding solutions and getting them accepted is some task in our profession. But, it gives a great sense of satisfaction," says S K Chandrka, DGM (Electrical and Avionics), Aircraft Research and Design Centre (ARDC), a prominent unit of Hindustan Aeronautics Ltd (HAL). "There have been some sleepless nights. I remember once a wire got cut inside the aircraft and I was really restless till we found the reason," says Chandrika, with over 26 years of experience.
City Express caught up with some of the women designers from ARDC, working with India's Light Combat Aircraft Tejas programme, to capture their mood ahead of the initial operational clearance (IOC) event scheduled to be held in the city on December 20. Despite being their first interaction with media in their career, these women showed little hesitation in replying to the queries. K Sharadha, AGM, Flight Test Centre who has close to 30 years of experience at HAL, said that the family support played a crucial role during all these years of hard work and toil, in realising the national dream called Tejas. "I was involved with the programme from 1995 and was part of the team that set up the infrastructure, telemetry ground stations and configuration of flight test instrumentation. My family was aware of the critical nature of my job and they stood rock solid behind me," says Sharadha a native of Tamil Nadu.
Hailing from Mangalore, Sumana Prakash, is a Chief Manger (Design) with two decades of expertise in aeronautics. She was part of the Tejas programme right from the first day of her joining HAL. The project just completed the drawing stages and the prototype was getting ready. "It is really a matter of pride being associated with Tejas and I am part of the electrical design team. I have gone for outstation trials to Leh and life throws up many challenges. I am also part of some of the future programmes of HAL. Being a woman, I need to make adjustments to my family life. Sometimes my children get upset with me for being on the phone even while at home, clarifying some test points with my colleagues," says Sumana.
Leaving a lucrative job with ABB, Rashmi Joshi, Manager (Electrical Design), joined HAL in 2001 and has been part of the Tejas project for the last 12 years. She has travelled to France on work and says that the job satisfaction is tremendous. "Nothing can match the thrill of taking challenges head on. Tejas wiring is really extreme with around 12,000 points. Life has become interesting with so many modifications being done to Tejas," says Rashmi, hailing from Nagpur. Her colleague S Meena, Manager (Electrical Design) had to stay away from family for close to 10 months, while she was sent on a deputation to Russia. "I had to take my son and mother along with me. Life was different in Russia and I learnt Russian as well. The varied experiences have boosted my self confidence," says Rashmi, hailing from Thirvananthapuram.
When asked about their views on being in a male-dominated domain and the difficulties they are facing in executing, everyone was all praise for their male colleagues. "We have come this far with their support as well. The team I handle have only two women and the rest are all men. I found no problems. Just that, I switch off my family matters completely when I am at work. Aircraft designers need to be emotionless when they deal with intense programmes such as Tejas," says Veena B, DGM (Prototype Assembly), who hails from Mysore.
Some of the designers came to the Tejas programme with rich experience of HAL's other projects like the Dhruv. Alakananda Suri, Manager (Iron Bird) from Lucknow joined HAL in 2000 and was put to Tejas project in 2011. As a Project Manager with HAL, she worked on a transfer of technology from Sagem (France). "It is a highly satisfying job and we were under tremendous pressure ahead of the IOC-2. The team work has been outstanding," she sad. The women brigade felt that it is because of the test facilities like the Iron Bird and the rigourous testing philosophy adopted, Tejas had thankfully not seen a single accident so far, unlike almost all the similar programs running worldwide.
Emphasising on absolute team spirit, Kalaivani D, a Deputy Manager (Electrical and Avionics) felt that in the design stream each and everyone work as one, shedding their grades and ranks. "We are so focussed towards achieving one milestone after another. It is a dream come true for all of us to see that Tejas is finally getting into an induction stage," says Kalaivani, who hails from Namakkal. "We are the real pearls of HAL," she adds, and the entire group bursts out laughing.
THE SHOP FLOOR SOULS: While the women completed their media mission and got back to their world of design, there was another group waiting in the wings for an interaction at the Prototype Flight Hangar. They were the men from the shop-floor, the real unsung heroes of Tejas project. No cameras have ever chased them. They come to work at times as early as 3 am to keep Tejas ready for the pilots to undertake the flight trials.
Avinash Kumar (34) is a Manager at the flight hangar who is with Tejas for past 11 years. "I am from Delhi and I've always wanted to be a part of the aviation industry. It is a great thrill to prepare Tejas for the flight, handling the snags and finally positioning the aircraft on the tarmac. My team consists of 50 people and we manage three aircraft. Never was there any dull moment for me since I joined the Tejas team," says Avinash. Echoing his views was S K Tripathi (52), senior master technician, who joined HAL in 2003 with a 20 years of experience working with the Indian Air Force. "My memorable moment was during the first flight of PV-5. It is a wonderful machine. Every time the aircraft takes off, it give immense happiness. I have accompanied Tejas to Goa, Jamnagar, Jaisalmer and Leh. It feels like taking our children for some entrance test," says Tripathi, who comes from Lucknow.
Being a rescue driver hailing from Tumkur, Balasubramaniam (35), plays a key role in ground support vehicle activities. He says for the last 10 years, he couldn't have asked for more, with the kind of exposure he got in dealing with different situations. "Even my relatives, family and friends are really happy that I am part of India's prestigious project," says Balasubramaniam. According to K Vijayan (54), hailing from Kerala, the Tejas team overcame many hurdles by coordination with the designers. "We undertook lot of corrective measures and though we are from shop floor, some of our suggestions are also taken into consideration," says Vijayan, an ex-IAF man, with 15 years of experience in HAL.
Similarly, Mohd Imtiaz (40), a technician, tells that plugging the snags is something he always enjoyed, while Shivkumar B H (42), a Senior Manager (Quality Assurance), says that to update new technology was a Herculan task. "We had to train the people so that they could handle the aircraft at ground level, independently," he says. Veeraiah (40), a Manager (Quality Assurance), emphasised how his team stuck to the safety features of the aircraft. "If something goes wrong, everyone will point fingers at us as we are the clearing wing. We will have to be available when pilots does the debriefing sessions," he says.
While these backroom boys were readying themselves to get a Tejas PV-3 ready for the flight, P G Jayan, DGM, Integration & Project Manager (LCA Mk-1), joined the discussion with his final words. "These are the true heroes of Tejas programme. The souls on the shop floor make things happen. There are days when they have worked for 16 hours. Having a great team is the biggest award you can get," says Jayan, who have logged 28 years in HAL.
As we wound up, the pilot of Tejas PV-3 was throttling up for another sky party.

Tarmak007 -- A bold blog on Indian defence: Tejas needs to cross 6 milestones in 15 months ahead of FOC
Express News Service
Bangalore: The Tejas fighter will have to cross 6 milestones in the next 15 months before the aircraft is given the final operational clearance (FOC). Tomorrow's (December 20) initial operational clearance (IOC) event, ahead of the expected induction of the first series production aircraft into the Indian Air Force (IAF) by March 2013, would pave way for the IAF pilots to undertake independent flight evaluation of Tejas.
Dr K Tamil Mani, Director-General (Aeronautical Systems), DRDO and Chief Executive Centre for Military Airworthiness and Certification, told Express that the integration of new missiles identified by the IAF will top the agenda in the FOC phase. "The aerodynamics, structures and the integration of the missiles with the radar are important events for Tejas now. We need to evolve the algorithm," Tamil Mani said. The beyond visual range (BVR) missiles from Israel – Derby and Python -- with a range of 70 km and each weighing 150 kg, have been identified for Tejas.
The Russian-made 23 mm GSH gun is the next in line to be integrated on the aircraft. Capable of firing at 3600 to 4000 rpm, the integration of this gun is seen as a challenge considering the vibrations involved during action. "Lots of surrounding LRUs need to be certified again for higher level of vibration. Ground firing or butt firing needs to be done initially before getting the gun onboard Tejas. The projectile speed of the gun is around 750 meter per second," he said.
Tejas will also have an air-to-air refuelling probe (Cobham, UK) in the FOC configuration. "We have started the integration work. Similar work was done on Jaguar and AEW&C (Airborne Early Warning and Control) platform. We have the expertise now," he said. The Tejas will also increase the angle of attack (AoA) from 22 to 24 degrees enabling the pilot to go for care-free manouvering.
The braking system of Tejas will also need to be improved. "The heat capacity needs to be increased. Else we will have to put a better cooling mechanism for the brakes, similar to the fans in the MiGs," Tamil Mani said.
The nose cone radome of Tejas is another part that is expected to get a re-look. "Now the radome is made of composite materials and we will change it to quartz. Today we are getting a radar range of 45-50 km and we need to improve the same to 80-plus km with the new material," the official said.

There is simply a lot of work on the MMR left.The nose cone radome of Tejas is another part that is expected to get a re-look.

What do they mean by radar range of 50 Km
A previous article talks about stuff I had already mentioned two-three years ago and even recently, that during the first IOC the AoA was 17 deg and improved to 18 deg a few months later. The speed is yet to cross Mach 1.4.
AoA should improve to 24 deg for FOC.
The aircraft is still in development, so give it time. Final MMR specs are supposed to be around 100 Km detection for a 5m2 target and a tracking range of 85 Km for a 5m2 target. These are a little better than Kopyo-M specs meant for Mig-21 Bison. I think even RDY-3 and Zhuk-ME specs are the same today. The move to AESA should considerably improve radar performance on Mk2. For Mk1 this is plenty.

What do they mean by radar range of 50 Km
people wrongly attribute it as problems with radar.
So it has nothing to do with Multi Mode LRDE-ELTA radar.
It has every thing to do with the composite material of tejas nose cone which is interfering with transmission and remittance of radar waves from the radar.
The DG himself has quoted saying that once it is changed from composite to Quartz there will be no problem.
Then all nose cones of the SP Tejas can be replaced with Quartz cones . SO it has no effect on the operational capability of the plane's radar design .
You can clearly see that the so called TOT to Sukhoi from rawmaterial stage won't help us in any way to produce fully modern 4.5th gen fighter even in radar nose cone area.
S unless tejas is finished to it's full potential, we now know that those DEEP TECH transfers have nothing to do with actually increasing our tech level.
Where is the source for these statements?
The MMR of tejas mk-1 itself has 650 mm antenna dia with peak power out put of 10 Kva for ten percent cycles and normal power out put of 5kw,
Stated detection range from B. Harry's article posted way back is 120 KM for 2 sq meter target and 150 Km detection range for fighter size target.
We will know the actual specs only after FOC is over once this Quartz cone is fixed.
Just because right now they have no plans to integrate anything more than 80 Km range BVR derby ,DG is saying 80 plus. Since it has bigger antenna dia and higher power out put there are no problems with range as per design of the fighter or radar.
grippen has just 600 mm radar antenea dia and a peak power out put of 8.5 Kw according to their own site.
SO there is nothing wrong with the MMar specs . it has every thing to do with the interference of the present composite nose cone with the radar waves, which will be remedied with the new quartz cone.
Also AOA does not improve for FO or IOC.
Right statement is flight envelope will be opened up to validate the fighter for so and so AOA and G forces as there will be no fresh design and R&D is going to happen between now and FOC with in a year's time, only minor changes .
Right now it is cleared till mach 1.4 . SO it can be operated upto mach 1.4 till FOC is the right choice of words,
Once the full flight envelope is opened up we will know whether it's top speed is mach 1.6 or 1.8.

papering over the four years delay in funding from 1989 to 1993,
sanctions delay of few years due to Nuclear tests and
delays of few more years due to FSED phase-II which started in 2004 when IAF requested higher launch stress inducing bulkier air to air missiles which added a few more years of delay.
All of the avionics and mission computers of Indian Sukhois come from tejas program,
And indian SU-30 MKis being made in india have high composite contents thanks to the tech evolved from tejas air frame,
It has HMDS aided high off bore WVR missile s which are not present even in Grippens and RAFALEs in service,
It has the better radar compared to Grippen and RAFALE if we take antenna dia and detection range ,
It has lower wing loading and higher TWR ratio than the Mirage-2000 in IAF fleet which determines the effectiveness in close combat,
Also 500 the test flights of tejas were for the purpose of building up a database for flight control laws for all fly by wire RSS platforms which will be designed in future,
It has a very low clean config RCS of lower than 0.3 sq meter , which gives it a crucial advantage of not being targetable by any of the radars in asian skies once it fires it long range BVR missiles, While it can target all of them owing to their more than 2 sq meter clean config RCS
Not a single fighter crashed in a 12 year 2500 flights long test flight regime,
Can land on and take off in Leh with weapons from day one,
Finally coming in with a price tag of 30 million dollar piece with most of the top notch tech that is present in any world class 4.5th gen fighter.!!!!!!
But all this is papered over by the toi guy and he wants to name it "jet-ayu" as if every one is lining up infront of his office begging him to give a name,!!!
The name of the guy is Rajat pandit and he does this each and every time he writes an article on tejas, saying as if the designers wasted all those THIRTY years sleeping on their job and it is just a Mig-21 replacement which has no other role to play, and the tech developed for tejas has no other uses, etc , etc,
but these guys will Que up and salivate in front of any foreign product as if it is manna from heaven!!!!!!
Contrast the above report with the one below!!!!!,

But @ersakthivel what puzzles me is why the official would not clarify that and understate the radar's capability by almost 40 kms? Since B Harry's article has there been any other article corroborating the claims? Given the MMR has a higher power output even I expected it to have better ranges than Gripen. What randome material do other fighters use? Also does the official mean search range or tracking range. Maybe there are some other issues to be sorted out before we get the maximum potential. Anyways great going upto now.

He is the head of the certifying authority CEMILAC explaining the parameters cleared for IOC-2 with the present composite nose cone.
he himself says with Quartz cone it will be 80 plus. And did not say the upper limit is 80 Km. he said 80 plus because the max range of BVR derby selected for tejas comes around to that range.
Once FOC is over we will know the max detection range of radar, because if there are no problems in nose cone material there is no way a larger dia antenna with more peak power output at 10 kw will give lesser range than smaller dia antennas with lower peak power output.
he himself says this is all due to interference from composite nose cone and not due to radar deficiencies.No problems are expected in radar as it is a joint venture with ISRAEL with back end processor from ELTA.

A ARAFLE will cost far more than 120 million dollars,
if you take the full life cycle spare support and MLU offers with huge forex outgo.
For example with no radar upgrade and no engine upgrade Mirage-2000 upgrade package costs about 40 million dollar a piece,
far more than the entire unit cost of far more close combat capable tejas mk-1
which has more Thrust to weight ratio than Mirage,
lower wing loading than Mirage
and has high off bore sight HMDS enabled crucial close combat WVR missile like R-73 which is not there in Mirage,
With ASTRA mk-1 and mk 2 tejas mk-1 itself will have longer range BVR missiles than Mirage even after upgradation.
Still the price of brand new tejas comes at about 30 million dollar a piece while upgrade for old Mirages cost 40 million dollar piece,
For the price of 126 RAFALE fleet we can field at least 600 tejas mk-2 fleet with no forex out go in total life cycle cost and huge upgrade cost if you take Mirage upgrade cost as a standard..
Tejas mk-2 will have more or less the same ASEA radar capacity of RAFLE and same long range 120 Km BVR missile as RAFLE.
So you can imagine how effective tejas is,

So, if Rafale does not offers enough bang for the buck, why has the IAF chosen it over all other options available to it ? Surely, the IAF folks know a little bit about aviation (if not much) & not all of them are a total nutcase or corrupt.
