LCA back at Jamnagar for weapons trials

After the Tejas LSP-7 successfully completed several weapons release test points at Jamnagar in July this year, three more limited series airframes (LSP-3, LSP-5 and LSP-8) are now in Jamnagar to bolster the gains made, and notch up more test points necessary for initial operational clearance of the LCA Tejas Mk.1 in December. The three platforms will undertake a slew of weapons release manoeuvres including releasing bombs and firing the Vympel R-73 missile, the only missile so far deployed on the Tejas.

The IAF has indicated the team testing Tejas is looking to achieve IOC-2 before Christmas, anywhere between Dec 19-24. However, there remain several test points still to clear, placing a great deal of pressure on the team. On November 6, Defence Minister AK Antony ordered the DRDO to ensure that Initial Operational Clearance and Final Operational Clearance of the LCA were completed on schedule, with both the MoD and IAF making it fully clear that no further extensions will be granted to the programme.

In August, Antony told Parliament, "Defence Research and Development Organisation (DRDO) and Aeronautical Development Agency (ADA) have been asked to strictly adhere to the planned schedules for Initial Operational Clearance (IOC-2) by end of 2013 and Final Operational Clearance (FOC) by end of 2014 to ensure timely induction of Light Combat Aircraft (LCA) in the Indian Air Force (IAF). Tejas is likely to be inducted in the Indian Air Force soon after the Initial Operational Clearance (IOC-2)." DRDO chief Avinash Chander has indicated earlier this year that the first three-four full rate production Tejas fighters would roll out of the HAL facility in December this year, the first of 40 ordered by the IAF.

The TWR ratio of 1985 was for a low tech LCA with none of the current advanced systems on board and was not capable of firing even R-73 ,

So there is no point in comparing it with the present capacities of tejas mk-1 whose wings were strengthened to carry R-73 , and the to be introduced Astra missiles along with a extra weight capacity pylon for carrying a 2 meter long heavy Elta EW pod, a refueling probe along with full EW suit a first for any Indian fighter at introduction and say only mk-2 will satisfy the 1985 ASR,

In the same page it is clearly mentioned that mk-1 is good enough for IAF and since Navy expressed the desire for higher powered engine IAF also upped it's demand,

LCA mk-1 can itself exceed many close combat specs of mirage-2000 in indian conditions was also stated by former NTSE chief Riaz Khokar.

Also it is clearly stated that most of the fuel increase is going to come mostly from the increase in dia of the all fuselage fuel tanks and larger space freed up in the wing will also lead to increased to fuel capacity not just from 0.5 meter plug in.

LCA is already flying with a extra ballast weight of 200 KG according to former NTSE chief Riaz Khokar,

Also the claimed 6400 KG weight in Aero india 2011 was before the roll out of LSP-7 and 8 which includes close to 400 Kg testing equipment weight.

Besides those 400 Kg testing equipment weight some weight reduction was also carried out on LSP-8 by eliminating few LRUs by combining their functions with other LRUs and we don't know how much of CEMILAC recommendations for close to 1 ton weight reduction was carried out in LSP-8.

SO we will get a clear pic once we know the empty weight of SP versions,

Also talking about manufacturer's Mig-29 STR and Mirage-2000 ITR along with their range figures is pointless.

In Indian hot and dry climatic conditions most of the top figures of those fighters from their makers are not achievable as those fighters and their engines were never tuned to give thier best in Indian conditions, this was clearly stated by none other than Cmde Jaydeep Maolankar,




Why? Mig-29 has best ITR and STR not due to advanced design , just by making it so short ranged due to two powerful fuel guzzling engines , No one makes such fighters any more. Because the fighters that excel in ITR use that in close combat to overcome their lesser STR along with high off bore WVR missiles and HMD facilities . SO range and weapon load along with reliable mission ready engines is more important than short legged fighters with two unreliable engines .

That is the reason why IAF asked MOD for 126 extra Mirage-2000s( which subsequently transformed into MMRCA tender )and not Mig-29s . It is not that they don't know the Mig-29 has more STR and ITR than the mirage-2000s

Which was clearly shown when LCA mk-1 itself exceeded the speeds of Mig-29 and Su-30 MKI at sea level in hot indian climatic conditions at skies above Goa in it's flutter test long back before weight reduction exercise and with more than 400 Kg of testing equipment on board,

Same will hold good for LCA mk-2 comparison with RAFALE,

and the link to the above page was twice posted once by me and then again by Kunal to refute the useless argument of MK1 could not even reach 1985 ASR and only mk-2 will reach it.

If some one gives a TWR in the ASR for a Mig-21 replacement with no 4th gen capacities and MTOW of just 12 tons and get a fully compliant 4th gen fighter with many EW facilities (including optical passive optical targeting and IRST according to the fact file article by B. Harry on Tejas by 2009 itself) along with refueling probe and 13.5 ton MTOW saying the goal is not reached is a faclie argument.

So brochure pasting specs from various fighters with different aerodynamic and mission profile and ranting at tejas mk-1 not meeting them all in a single platform is pointless and will lead to IAF forever remaining Imported Air force

Also we must note that in the following quote,

- He was full of praise for the handling of the Tejas. It's a true delight to fly and both he and Grp Cpt Suneet Krishna have tremendous confidence in the aircraft itself. He said that they both push the aircraft to its current limits without any worry since the FCS is very good. He did mention that they didn't push the Tejas Mk1 to its limits at the airshow but just wanted to display that it is maneuverable enough.
that tejas mk-1 LSPs( up to 5) were never ever pushed to even their opened flight envelope limits of 22 aoa and 6G limit, that too with 400 Kg testing equipment on board in any aeroindia display, giving it a STR of 18 deg per second ,

in HOT INDIAN CLIMATIC conditions not clod weather conditions in most foreign airshows which delivers more engine thrust. hot conditions simply sap the peak engine power

Still tejas mk-1 under these partial capability conditions did a vertical loop in 20 seconds . RAFALE in it's indian display has also completed a vertical loop in the same no of seconds,

This 18 deg ASR was the original ASR given by IAF for full 9G load and just 5.5 ton empty weight along with 12 ton MTOW,

Now in Aeroindia 2013 the Tejas mk-1 which weighs much more than the original 5.5 ton weight and with extra 400 Kg of testing equipment on board , well within the partially opened flight envelope limits of 6G and 22 AOA pulled the same 18 deg AOA .

After that Aero India LSP 7 and 8 with auxillary intake and many performance improving and weight saving suggestions implemented by ADA according to CEMILAC suggestions have flown .

The only statement that came after their flights were ,"Tejas has cleared all IAF expectations in close combat specs " from an IDRW article and nothing else. Now no one talks about watered down specs or shortage of close combat performance any more.

The design AOA limitations of tejas was close to 35 deg according to B Harry's fact file article Radiance of tejas . How much was reached is still not disclosed,

Also B Harry's fact file article Radiance of tejas explicitly states that Tejas fuselage follows area rule for minimizing super sonic drag

Internal fuel capacity of world 4th ~ 5th Gen fighters

Su-30MK: 34.9%(Empty weight: 17,700 kg,Internal fuel: 9,500 kg)

Rafale: 31.4% ~ 33.6%(Empty weight: 9,500 ~ 10,220 kg,Internal fuel: 4,680 ~ 4,800 kg)

JAS-39NG: 30.6%(Empty weight: 7,100 kg,Internal fuel: 3,130 kg)

MIG-35: 28.6%(Empty weight: 12,000 kg,Internal fuel: 4,800 kg)

Tejas: 27.0%(Empty weight: 6,500 kg,Internal fuel: 2,400 kg)

JF-17: 26.3%(Empty weight: 6,450 kg,Internal fuel: 2,300 kg)

JAS-39C: 25.0%(Empty weight: 6,800 kg,Internal fuel: 2,268 kg)

This is a fair comparison of fuel fractions with just internal fuel , and the same percentage will more or less reflect with external fuels also,

So Tejas mk-1(which still has 400 KG of flight test equipment on board, removal of them will lead to even better fuel fraction) itself has much better fuel fractions than grippen C/D with more TW ratio and lower wing loading,

Tejas mk-2 will easily compare to RAFALE which has just 4 percent more in fuel fractions than Tejas mk-1.

So in indian conditions there won't be no issues with range of tejas mk-1 or mk-2 in useful combat configuration if we take into account that four tejas can be operated for one RAFALE if we include total lifecycle costs and upgrade costs,

So there is no way Tejas can be faulted on weapon load or range.

Admiral J G Nadkarni (retd)
The sad tale of the LCA
Last month, Indian defence authorities quietly announced that India's prestigious Light Combat Aircraft, originally to have become operational in 1995, will not achieve that status before 2015. The euphoria over the first flight of the prototype a few days later, however, helped to push that stark news off the front pages.

The LCA programme was initiated in 1983 by the Defence Research and Development Organisation, with three widely publicised assertions. One, that it would be an indigenous project catapulting India into the rarefied ranks of global aviation powers. Two, the aircraft would enter frontline squadron service by 1995. And three, the project would only cost Rs 700 crores (Rs 7 billion).

What actually happened between 1983 and 2000? First, let us take the promise of indigenous development. In 1986 an agreement was quietly signed with the United States that permitted DRDO to work with four US Air force laboratories. The to-be-indigenously-developed engine for the LCA -- Kaveri -- was forgotten and the US made General Electric F-404 engine was substituted. Radar was sourced from Erricson Ferranti, carbon-fibre composite panels for wings from Alenia and fly-by-wire controls from Lockheed Martin. Design help was sought from British Aerospace, Avion Marcel Dassault and Deutsche Aerospace. Wind tunnel testing was done in the US, Russia and France. As for armaments -- missiles, guns, rockets and bombs -- every last item was to be imported.

As for operational induction, anyone who knew anything about fighter aircraft development or the capabilities of the DRDO would have known that the envisaged 12-year time frame (1983-1995) was /pure make-believe.

Yet, as late as 1990, DRDO asserted that the 1995 target would be met. It was only when 1995 drew closer that the talk shifted from operational induction to test flights. In 1998, the defence minister stated that the first test flight would take place in 1999. The first flight finally took place a few days ago, 17 years after the project started.

As for the project cost, the original budget was Rs 700 crores. It was later revised to Rs 3,000 crores (Rs 30 billion). It would easily go past Rs 10,000 crores (Rs 100 billion) before the aircraft is inducted into operational service. And that is with DRDO incurring only about a quarter of the overall development costs. Not included are the cost of the huge amounts of foreign equipment being fitted; engine, radar, electronic warfare and communication equipment, high-stress body panels, cockpit displays and the entire range of armament.

Initially it was stated that the per copy price of an LCA would be Rs 10 crores (Rs 100 million). It would be a miracle if the LCA can ever be produced at less than Rs 150 crores (Rs 1.5 billion) a copy. And if the LCA is eventually inducted in 2015, what will the Indian Air Force get? It will get an aircraft at best comparable to first generation F-16s.

One of the DRDO's favourite phrases is 'state of the art,' and according to them everything of the LCA is state of the art. In the fighter aircraft field, to be state of the art, at least from 1990, an aircraft must be designed for 'stealth', that is having virtually no radar or thermal signature. Not even DRDO has so far claimed that the LCA is a stealth aircraft, or that it is capable of being made into one. Forget stealth, the LCA is incapable of any significant upgrading at all during its lifetime. It is a very small, single-engined aircraft tightly packed with equipment. It cannot be fitted with a bigger engine or expanded avionics.

What prompted the DRDO to conceive the LCA when Israel, technologically far more advanced than India, had abandoned its Lavi fighter project after spending more than $ 2 billion on it? Aircraft development costs had mounted so much by then that far richer-countries compared to India such as Britain, France and Germany had realised that unless they formed multinational consortia it would not be possible for them to develop sophisticated, modern aircraft. That is why beginning the late 1970s we have had Eurofighters and Eurocopters, where three or four countries share costs and buying commitments.

It can be said with certainty that the LCA will never become a frontline fighter with the Indian Air Force. The Mirage 2000s and the Mig-29s that the air force has been flying from the 1980s have superior capabilities to any LCA that might be inducted in 2015, 2020 or 2025. So the most prudent thing for the government would be to immediately terminate the LCA project. National and individual egos have been satisfied after the first flight.

The Rs 3,000 crores or so that have spent so far could be put down as the price of a valuable learning experience. We would have undoubtedly gained valuable knowledge in many areas of aircraft design and engineering. But of much greater value, we would have gained the understanding that defence R&D is not a make-believe game to be played by exploiting the fascination for techno-nationalism.

The LCA ranks alongside DRDO's other monumental failures such as the Arjun tank, the Trishul and the Akash missiles, and the Kaveri engine. The time and cost overruns on these projects have been enormous. The story of the Arjun is well known.

With the induction of the T-90, there is no way the Arjun is going to spearhead India's armoured divisions. In fact there are many who believe that the T-72 inducted two decades ago is a better tank than the Arjun. The reality of Arjun seems to be finally sinking in, and it would appear that it might end up not as a battle tank, but as a platform for a 155mm howitzer.

The short-range, surface-to-air-missile Trishul was to be fitted on three Indian Navy frigates in 1992. A decade later, the missile is still carrying out "successful" tests, long after the frigates have been completed. The same story goes for the medium-range, surface-to-air missile Akash and the anti-tank missile Nag.

During the last 20 years, DRDO has fine-tuned the art of selling projects. To start with, don't be timid and aim low. In true Parkinsonian style, the more ambitious the project, greater the chance of it being sanctioned. When the presentation is made to the minister, be generous with phrases such as "state-of-the art". Also mention that we will be the third country in the world to produce the equipment. (It is always the "third" as even the minister knows that the USA and Russia already produce the same).

If a service chief demurs, make snide remarks about how the services want to import everything. And keep the estimated cost of the project absurdly low. Once the project is sanctioned, feed the media with a steady stream of unverifiable tidbits. Bring out a mock-up model and show it round at the Republic Day parade and defence exhibitions.

In recent times DRDO and India's defence services have evolved a modus vivendi. No longer does DRDO oppose imports, provided they are allowed to continue with their projects. Thus, import Su-30s and develop the LCA. Import T-90 tanks and produce Arjun. Import Israeli UAV and continue with a similar indigenous project. The only victim in this you-scratch-my-back-I-scratch-yours game is the Indian taxpayer, who unfortunately does not seem to care.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
It is a time honored tradition for retired services guys who don't have any knowledge about the design R&D phase of a fully RSS compound delta fighter like Tejas to write kiddy stuff like this.

"LCA ranks along side AKASH and ARJUN as a monumental failures" of DRDO. Really?

After trials orders are piling up for AKASH and mk-2 version development is in progress. Also Arjun has proven itself superior to T-90 in trials even in mk-1 version itself.
And Tejas mk-1 is better than Mirage-2000 in key respects according to former NTSE chief riaz khokar.

So what is the admiral doing by writing such stuff? Spurious stuff like this are always picked up by trolls trying to bet down Tejas project and passed as of critical analysis from Indian defence personnels.

Note the same trollish comments Tejas will be inferior to Mirage-2000even in 2015 and it is a little fighter packed with instrument.

but test pilots have rated tejas more capable than Mirage-2000 even within restricted flight envelope of 6Gs and 20 deg AOA .

Many retired service chiefs salivate in front of grippen NG , which too is packed with instruments and has the same small dimensions as that of Tejas and also a single engined plane. It has a smalled radome dia than tejas as well.

the following is another article by brochure specialists on the tejas effort. This one is by --August 5, 2002 edition Vol 157 Issue 6 Page 32 by Neelam Mathews. i

It is astonishing how these guys who have no knowledge of technical issues , sprout BS like this!!!!!

Watch out for typical blind eyed bytes like, without even knowing that it is the russians who designed make Mig-21 engines and not indians

"Retired group Capt. Rajesh Chidambaram sees reason for concern. ``In the recent MiG-21bis update, nothing much has been done to improve the engine, which had been giving problems,'' he said. ``The time is not far away when the LCA, too, will be manufactured by HAL. One wonders what will happen to the already worrisome safety record then.''
"


and all knowing industry critics shooting shit like,

industry critic said. ``The LCA project will continue to provide employment to government officials and go on and on till the cows come home.''The project has experienced significant cost growth. ``The original project cost $114 million, has gone up to $612 million today, and there seems to be no sign of a commitment to completion, as [the LCA] is politically motivated,'' the industry critic said. ``The LCA project will continue to provide employment to government officials and go on and on till the cows come home.''
This is from Aviation week and Space Technology the most reliable source in aviation and Aerospace.


After postponements and technical delays, the second technology demonstrator (TD-2) for India's long-delayed Light Combat Aircraft has been flown at Bangalore, but the aircraft is unlikely to see service before 2010.

The third of seven LCA prototypes is due for flight testing by the end of the year in preparation for an anticipated order of eight aircraft. Once full production begins, the LCA is expected to replace India's aging fleet of some 450 MiG-21s. They have been the subject of repeated accidents, including one three months ago that prompted a grounding of the Indian air force's MiG-21 fleet (AW&ST May 13, p. 34).

But recent press reports saying that the government is looking for an outside vendor to supply a MiG replacement indicate that patience is wearing thin for a program that started 19 years ago. The Indian air force currently flies about 39 squadrons. It is expected to have 55 by 2020.

Once showcased as the symbol of U.S.-Indian defense friendship, the program has fallen prey to both technical and political problems.

Program Director Kota Harinarayana said the LCA is intended as a platform for India's present light fighter needs as well as for future weapon systems. The air force also fields heavier fighters, including the Su-30, MiG-29 and Mirage 2000.

The project has been managed and monitored by the Aeronautical Development Agency and nearly 80-odd small and large defense and other related organizations under the umbrella of the Defense Research and Development Organization (DRDO). Hindustan Aeronautics Ltd. (HAL) is the lead manufacturer, with responsibility for its Kaveri engine, airframe, systems integration and fly-by-wire control systems.

Indigenization is the biggest technical challenge. An LCA official defended the program's long gestation period as the result of politics, not design. ``The project faced delays because of technological and political challenges,'' he said. ``As a result, we had to find solutions by developing appropriate indigenous technologies and equipment.''

The reference is to sanctions imposed by the U.S. after India's Pokhran nuclear bomb tests in 1998. (Indian scientists working in different fields linked to the LCA project at Lockheed Martin in Binghamton, N.Y., were asked to return to India.)

But another industry observer says that's not the whole story. ``While they may say it was U.S. sanctions imposed for 2.5 years that stalled the project, they could never identify the right vendors'' to supply components, he said. ``They want to do everything themselves without having the necessary capabilities. With technology available abroad, does it not make sense to have sourced it?''

As an example, he said that when compressor blades were required for the Kaveri engine, negotiations were abruptly shut off with French suppliers in favor of an indigenous small supplier from Gujarat.

``The main reason for the delay is that the exact requirements [for the aircraft] were not laid out,'' he said. ``There has been no strategy or planning and no commitment of dates to deliver.''

Retired group Capt. Rajesh Chidambaram sees reason for concern. ``In the recent MiG-21bis update, nothing much has been done to improve the engine, which had been giving problems,'' he said. ``The time is not far away when the LCA, too, will be manufactured by HAL. One wonders what will happen to the already worrisome safety record then.''

The project has experienced significant cost growth. ``The original project cost $114 million, has gone up to $612 million today, and there seems to be no sign of a commitment to completion, as [the LCA] is politically motivated,'' the industry critic said. ``The LCA project will continue to provide employment to government officials and go on and on till the cows come home.''The project has experienced significant cost growth. ``The original project cost $114 million, has gone up to $612 million today, and there seems to be no sign of a commitment to completion, as [the LCA] is politically motivated,'' the industry critic said. ``The LCA project will continue to provide employment to government officials and go on and on till the cows come home.''

Is that correct? 120 kms against 2 m^2
B.harry is definitely the most authoritative technical source when it comes to tejas and he is no troll like most of the retired services seniles who know no shit about aerodynamics and spew their bile like there is no tomorrow,

The vayu issue which had a feature on tejas also quoted the same rang for a fighter sized target.And ADA's chief's interview that states that tejas mk-2 which will have more or less the same radome dia will interfaces to fire the 120 Km range Meteor missile proves that.

Numbers are correct for the radar,
While originally planned to be fitted on production aircraft, delays in the development of MMR prompted the DRDO to co-operate with Israel Aerospace Industries to integrate a Hybrid version of the EL/M-2032radar for use with the Tejas.[40] The EL/M-2032 radar used in LSP-3 has a detection and tracking range of up to 150 km in air-to-air mode, the air-to-ground mode generates high resolution radar imagery of locations at up to 150 km, and air-to-sea mode can detect and classify naval targets at ranges of up to 300 km.Another track System is an infrared search and track system (IRST)[73]
this is in Wiki and a IAF magazine vayu's article on LSP-3 also mentions the same range, i will find it and post a link.

people who say it is wrong can give a source for the radar detection range of Tejas. But I am hundred percent sure no one can cite any source.

System (TACAN). The primary sensor,
and mission critical system of the Tejas is
its Multimode Radar, jointly designed and
developed by ADA, HAL, LRDE, ECIL
with ELTA of Israel and is reportedly
based on the EL/M-2032 which is an
advanced pulse Doppler, multimode Fire
Control Radar intended for multi-role
fighter aircraft, with origins in the Lavi
project.
This radar is designed to work in airto-air, air-to-ground and air-to-sea modes
and has high resolution ground mapping
with many other features. The RWR is
designed and developed by DARE and
systems are designed and developed by
SLRDC, HAL at Hyderabad. With these
systems integrated and flown, the Tejas
"is very close to final production standard
aircraft as planned to be inducted into the
IAF according to ADA

The coherent pulse-Doppler Multi-Mode Radar in development is designed to keep track of a maximum of 10 targets and allows simultaneous multiple-target engagement. Jointly developed by the LRDE and HAL Hyderabad, the MMR is being designed to perform multi-target search, track-while-scan (TWS), and ground-mapping functions. It features look-up/look-down modes, low-/medium-/high-pulse repetition frequencies (PRF), platform motion compensation, doppler beam-sharpening, moving target indication (MTI), Doppler filtering, constant false-alarm rate (CFAR) detection, range-Doppler ambiguity resolution, scan conversion, and online diagnostics to identify faulty processor modules. While originally planned to be fitted on production aircraft, delays in the development of MMR prompted the DRDO to co-operate with Israel Aerospace Industries to integrate a Hybrid version of the EL/M-2032 radar for use with Tejas.The EL/M-2032 radar used in LSP-3 has a detection and tracking range of up to 150 km in air-to-air mode, the air-to-ground mode generates high resolution radar imagery of locations at up to 150 km, and air-to-sea mode can detect and classify naval targets at ranges of up to 300 km.
The development of an AESA radar for the Tejas is expected to begin pending the selection of a developmental partner. The contenders for the contract are the European Consortium EADS and the Israeli company Elta. The initial contract will see the co-development of 10 prototypesThe electronic warfare suite is designed to enhance the Tejas' survivability during deep penetration and combat. The LCA's EW suite is developed by the Defence Avionics Research Establishment (DARE) with support from the Defence Electronics Research Laboratory (DLRL).This EW suite, known as "Mayavi"(Illusionist), includes a radar warning receiver(RWR),Missile Approach Warning(MAW) system self-protection jammer, laser warning system, missile approach warning system, and chaff/flare dispenser. In the interim, the Indian Defence Ministry has revealed that an unspecified number of EW suites had been purchased from Israel's Elisra for the LCA prototypes.

Ericsson PS-05/A pulse doppler radar
(can count anchored ships and follow road traffic at at least 90 km
and detect typical fighter sized targets at 120 km).
Total mass 156 kg, antenna assembly 25 kg, antenna diameter 0.600 m,
Max power consumption 8.2 kW (114/200V 400Hz AC) and 250 kW 28V.
Predicted MTBF: 170 hours (air operation)

Cooling air: 85g/s at 0oC, Cooling liquid: 3.5kW to be absored.
Electrical interface: MIL-STD-1553B data bus and fibre optic video
output to the display system.
Air to air scanning at 60 (at first 50) deg/s in either 2 120 deg bars,
2 60 deg bars or 4 30 deg bars. Surface mapping and search across 5 x 5 km
to 40 x 40 km with GMTI speed adjustable by the pilot.
Four basic air to air modes: Track While Search, Priority Target Tracking
gives higher quality tracking for multiple targets, Single Target Track
gives highest quality data, Air Combat Mode for short range search and
automatic target capture.
The above is the radar specs of grippen from

JAS 39 Gripen - an overview: Basic data

Antenna diameter 650 mm
Antenna gain 33 dB
TWT Power Output 6.5 kW (increaseable to 10 kW, 10% duty cycle)
Range 120 km against 2 sq.m RCS aerial target, >150 km for surface targets against sea clutter
All Up Weight (AUW) 130 kg
To keep the radar up to evolving standards, a new Advanced Signal and Data Processing Unit based upon Power-PC chips, has been developed to replace the older unit.

The above is the data for Tejas Lca from authoritative source B. harry whose article "the radiance of tejas is the most detailed fact sheet than any horse shit spewn by AWST neelam mathews types and retired service senile personnel types with zero engineering knowledge"
ACIG Exclusives : Tejas Resources

The Grippen radar has a 600 mm antenna with 8.5 kw max power consumption and it's makers claim that it can detect fighter size targets at 120 Km. that's why it has become the first fighter to be integrated with 120 Km range BVR missile meteor. Even at that point of time a fake technocrat here claimed that a small fighters are not meant to fire longer range BVR missiles and grippen can not fire it's Meteor at it's full range only "heavy class fighter like Su-30 MKI can do"

Since tejas has a 650 mm dia antenna and 10 kw max out put for it's MMR it is only logical that it can detect 2 sq meter target from 120 Km as with 600 mm dia 8.5 Km max output MMR grippen manages to track fighter sized(no RCS is given ) targets at 120 Km.

In tejas mk-2 the fuselage dia is going to be increased by more than 120 mm. So there is a prospect of it's tracking range going much higher than the present 150 Km.

Thats why the ADA chief claimed that Meteor launching interface can be present on tejas mk-2 because it has the radar tracking range more than the meteor missile range of 120 Km.

Tejas mk-1 itself can have Astrs mk-1(80 Km range) and mk-2(100 plus Km range as it's primary BVR ). Or if IAF demands it can integrate any russian long range BVR in IAF stockpile as it has the radar range equivalent to Su-30 Mki in this regard.

but fake gurus and retired service senile types who spew bile on tejas can not digest this stuff and continue to spew bile on tejas.

The Hindu : National : LCA to be fitted with Israeli multi-mode radar

P.S. Subramaniam, Programme Director, Aeronautical Development Agency (ADA), the defence laboratory that is designing the LCA, told The Hindu that "airworthy units" of the Israeli – manufactured MMR would be arriving here early next week for integration into the aircraft. The Elta designed and developed MMR, Elta EL/M-2052 which will be an interim option since India is developing an indigenous one, has already undergone tests on the flight test bed and ground rig in Israel.
the above is a 2008 dated news interview.

The present status updated till now is only the back end processor for tejas's MMR is from Elta the antenna with T/R modules all are successfully made here. if people have any other source they can please post.

What is the radome dia of Mig-21 bis , Mirage, RAFALE and JF-17? If any one has source please post.
