$93 million is not the unit price of LCA MK1A. Not even close.

We cannot reach a definite unit cost with lot of things still in the air.

With just 40 units confirmed so far, needless to say the cost of engine, radar and other LRU will not low.

Moreover LCA is been built for IAF. Not for exports. Most of the money will be going back to Indian industries.

Neither will know the savings, when Indian AESA and Astra are integrated.

The prime issue is numbers. We need to get off this piece meal order business.

I understand fixed costs (production setup, technology (r&d) cost, etc) is something have to be done, and not recoverable (meaning included in the product cost for sales - or this is where other countries have done things at economies of scale). Removing all variable costs (i.e, line-items required for production); we could isolate what is fixed vs variable. How much of the $7.7 given to HAL is invested as fixed cost?

I am sure, they include establishing the additional production line to manufacture the Mk1A.

JayS wrote:Avionics and weapons systems are being designed with open architecture for quite a while now. I think you are confusing open architecture with "openness" (as in open source) of a system. An open architecture system need not give freedom and ease of modifications to anyone but the developer. In today's world no OEM will think of making closed architecture subsystems for fighter avionics. Otherwise the cost of further modifications and development in the same system would be so much that it will quickly erode its cost competitiveness (goes for both HW and SW).

Optimisation of firmware for HW is not contradictory to requirements of modularity in the larger system, it can be accommodated within the open architecture framework as long as each module/sub-system is individually optimised. After all we are not going to install firmware (or even SW for that matter) of one radar onto other like we install Windows OS on various HW).

As far as the "openness" is concerned which can enable third party to integrate other systems with the radar, that is controlled by only API (physical or SW). If Radar OEM gives API to the third party they can do the integration with ease and at the same time Radar source code is not compromised. Having an API designed into the system and sharing it with others are two different things. Also note that with the API, the OEM can control the level of access to the source code. It can be either limited to the bare minimum interface thats required for given capability or it could allow one to access each and every functionality in the source code.

Whether a Radar is open architecture or close architecture, the interface can always be reverse engineered, as long as there is an interface. Only thing is cost and efforts increase if one has no access to API and for a closed architecture.

This is quite the same as how many commercial SW tools operate. They have a API designed for their SW. You have to buy the API license separately to be able to build own apps or integrate third party tools with this particular SW using the API. Please note I am not talking about the scripting interface that is available or user defined functionality interface that is available for the user from front end (GUI/TUI) for automation or customisation purpose. The API I am referring to link the user to the back end source code directly.
As tech as evolved the distinct well defined boundries of radar, radio communication and controls have gotten blurred into a nebulous cloud. AESA is known to also incorporate rf communication channel with various attributes including LPI and jam resistance that is not only used for inter aircraft datalink but also missile comm & control. Now it depends on architect of the open system interface, if a clean API is abailable, perticularly if comm interface has some protocol specific timing accuracy / agelity reqmts.

So any one making a system outof Meteor (or any other missile) will need acess to practically all aspects of the hardware and sourcecode. Code isolation is desirable but almost impossible to achieve in small qty volume mil system.

Given the above it is best to make and grow your own national ecosystem of radar, missile and communication gear based on modern-day AESA, DSP, SD(software defined) Radio, sensor fusion.

So IMHO IAF & HAL made wise decision to forgo METEOR brand name in lieu of similar capability indigenous ecosystem that Bharat own or controls. After all IAF ASR (Air Staff Requirement) is a living document and the reason the LCA ASR of 1988 has morphed to an ASR that demands LCA mk2 capabelity.

The initial batch is being produced with parts produced from private vendors on a prototype basis..
So the cost of these parts will be much higher than when they are produced as part of a serial production....

That might be the reason for bloated costs of the first batch...

Don't know if you followed PM Modi's speech in Rai Bareilly. Do listen from 35:10 onwards. PM Modi spent close to two mins on Tejas.

https://www.youtube.com/watch?v=DEfWPkNwErs

PM Modi called it India's Glory, mentioned that Tejas program was deliberately made moribund by previous govt, that in July 2016 Tejas was inducted in 45th Squadron, 83 MK1As have been conclusively ordered, and that HAL was given mandate to invest 1400 crs to double manufacturing capacity.

Details all well known but of course it is not lost on anyone, that the program was literally taken out of ICU, has enough power to fly on its own, and is now fantastic example of Made in India.

He doesn’t have a point, Admiral?
In a path breaking achievement, the Defence R&D Organisation (DRDO) has indigenously developed an “electronic warfare” (EW) system for the Indian Air Force’s (IAF’s) fleet of 60 MiG-29 fighters.

Yet, when buying EW systems for the Tejas Mark 1A fighter that Hindustan Aeronautics Ltd (HAL) is developing, the aerospace firm signed a contract on October 26 with Israeli firm, Elta – a subsidiary of Israel Aerospace Industries (IAI).

The indigenous EW system was developed under “Project D-29” by the Defence Avionics Research Establishment (DARE), a DRDO laboratory, in partnership with Israeli firm, Elisra and Italian firm Elettronica.

The IAF, delighted with the outcome of Project D-29, is about to accord it final acceptance. Bharat Electronics Ltd (BEL) will manufacture the indigenous EW systems for upgrading the MiG-29 fleet.

Under the Defence Procurement Procedure of 2016 (DPP-2016), the D-29 EW system falls squarely in the category of “Indian designed, developed and manufactured” (IDDM) equipment, the highest priority for procurement. DPP-2016 mandates that, if equipment is available under the IDDM category, it cannot be procured under other categories – such as “Buy Global” or “Buy and Make (India)”. This is to sponsor Indian design and development of equipment.

Yet, the Ministry of Defence (MoD) and the IAF, disregarding the success of Project 29 and its IDDM status, permitted HAL to buy the Israeli Elta EW system.

Something is seriously wrong with him. This is what he wrote in 2015 -
"Tejas designers admit the absence of a jammer to throw enemy radar off the scent is a key vulnerability of the Tejas. While designing the fighter, they simply ran out of space for an internal jammer. With the IAF dropping its insistence on an internal jammer, ADA and HAL have now offered an "external jammer pod"."

Many possible valid reasons:
1) insurance against failure of D-29
2) diversification of EW suites
3) Israel decides on "spreading the wealth" between IAI/Elta and Elbit/Elisra

In his bid to stay relevant, Shooklaw is trying his darned best to light a fire under every single deal - learning from Rahul's Rafale Pitch no doubt.

Chola Saar, what level of qualification does he have to comment on anything on the Tejas program? This is the same guy who whined about Tejas not having the Meteor missile. He does not research squat and then puts out articles like he is an authority on the subject. He is cherry picking stuff off the DPP (Defence Procurement Policy) and just creating controversy where none exist.

Questions to ponder...

1) Has the D-29 EW system even been cleared for the Tejas?

2) Does anyone honestly believe it is that simple? Take a system from one plane and just slap it on to another? What is this? Lego for the age group of 8 - 12 year old children? What happens to testing and certification?

3) In his own article, he writes that the D-29 EW system was developed in partnership with Israeli firm, Elisra and Italian firm Elettronica. Then later on in the article he states that the Israeli government stopped Elisra from developing the D-29 EW system and pushed for Elbit - another Israeli firm - to participate in an EW system for the Mk1A. What does Shukla want HAL to do? Invade Israel and arm twist the Israeli Govt to force Elisra to develop the D-29 EW system for the Tejas?

4) To counter the above argument in Point 3, Shukla then states this in the following paragraph ---> In January 2017, Elisra wrote a letter to Air Chief Marshal BS Dhanoa to nominate the D-29 EW system for the Mk1A. How he got a copy of such a letter is a mystery even greater the existence of Yeti the Snowman! But let us assume he is CCed (Carbon Copied) on *ALL* correspondence between Air HQ and Elisra. But he only states that the Israeli Govt shot down Elisra from developing the D-29 EW system! He then also claims that the IAF did not respond to that letter from Elisra! How would he know such a thing, to make such a bold claim? Apart from writing fiction in his blog, does he work as the typewriter and postman at Air HQ to make ends meet?

To paraphrase Titash, he is pouring gasoline and then lighting a match on every deal under the NDA Govt - hoping one will stick. The fake "Rafale Scam" failed spectacularly, so now he is on the Tejas bandwagon.

I do not want to bring politics in this thread. But this is not about the Rafale or the Tejas or the IAF or the Armed Forces....but this is pure hatred for the Modi Govt. The Congress did squat and like dogs in the manger, will not allow the BJP to do anything either. And their hatred for the BJP Govt goes far beyond policy. The Congress is playing the game of demagoguery to malign the BJP.

An EW system needs to be compatible to radar and other electronics, please read up on the Siva pod for Su-30 MKI. It will take us some time to develop one which can be compatible with El 2052 which means huge delays. It is not plug and play. We have working for years to get one compatible with Russian Electronics and Radars The Good Colonel is not correct on this one.

Selection of Elta 8222 pod is a disappointment. I guess the decision was taken simply to have a system fast and have it compatible with the radar.
For a desi solution, it would have to work in conjunction with the Radar and that development would delay the aircraft by maybe 1 year or more. However, given that it is an external pod, maybe the effort could have been made.

I think the desi pod will only come with the Uttam aesa radar. The remaining hope is for the 32 IOC and FOC aircraft to be upgraded to MK1A standard, with Uttam and indigenous EW pod. Will be a good stepping stone for the MK2.

With regards to the cost of the MK1A, I guess even the development cost of the plane would be included. Remember, the MK1A is a HAL initiative. All the flight testing, integration of the radar and then weapons with the radar etc. are all going to be done by HAL. Increasing the quantity by say another 16, would help bring down the cost. Plus the Elta 2052+8222 combo will also cost a fair bit.

Jay - thanks for explaining - appreciate what you are saying. I suspect that there may be performance issues in the interface or that the cost of reverse engineering is prohibitive - and possibly invalidates any warranties, etc.

of course [not to talk politics - :mrgreen: ], HAL and Thales [after Reliance cock&bull story by DDM], are in denial of any partnership! so, the DDMites have a strong association of DARIN3 done HAL friends to enable Mk1a.

why these guys really care about technical, or techno-economical analysis? someone perhaps bring out those points, but be careful, DDMs will steal such analysis.

Uttama decision is unripe! is da message.

Was just reading the AESA RFQ documents from HAL (on Trishul blog, hence not linking it here) and it is clear that :

1) HAL clearly states that the EW suite (Digital RWR, podded jammer) must be compatible with the AESA radar being supplied. Hence, the choice of the EW suite is more dependant on the choice of the radar- and being the respondent to the RFQ, IAI/Elta chose to offer the EL-8222 WB jammer. Likeliest reason being that they are confident of these two (Elta 2052 and EL-8222 WB jammer) working together. They are being held responsible for the integration of the AESA radar and EW suite and that must surely have had a big say in what they offered.

2) IAI/Elta will also be responsible for designing and developing, testing and qualifying the radome for the LCA Mk1A.

3) IAI/Elta will also be responsible for integration of any third party BVR missile as per LCA Mk1A requirements

4) Purchase will be made in 3 stages -
Stage 1- 24 sets purchased directly from the supplier
Stage 2- 08 sets to be supplied in SKD form to HAL to build
Stage 3- 48 sets to be manufactured by HAL with ToT for manufacturing these

5) HAL will receive ToT for overhaul and repair for the full life cycle repair and overhaul of 80 sets

6) Transfer of Intellectual property rights- HAL shall have worldwide exclusive right to sell and support the AESA radar and EW suite being procured for the LCA Mk1A and its variants. Can be both for indigenous programs or export programs (basically indigenising the radar)

7) Transfer of Intellectual property rights- Vendor cannot sell the radar developed through this RFQ to any other customers or transfer the IPR of the system to any third party without HAL's consent, for indefinite period of time

Similar approach for the EW suite as well

SaiK you are in Shukla mode. This price you came up with.
The article said 83 Mk1A for $7.7B the costs could include for infrastructure and whats called rate tooling.

So please don't add to the fire your own can of kerosene.

CAG will eventually tell us the price per aircraft.


And this spurred another dozen posts as follow-up.

Actually, a short summary of cost of Tejas can also be added to the 1st page. We would have plenty of articles online to quote from, especially the ones where MOD gave money to HAL for protypes, SP's, assembly lines etc.

HAL had actually given a price for the 83 MK1A at 463 crores rupees ($66M at current exchange rates) per plane earlier this year.

https://www.thehindu.com/news/national/ ... 421608.ece

This new figure of $93M must include new accounting methods.

This.. except he aint 'the good colonel'. He is a dirty rat.

An EW system has to be compatible with the different radar modes. There is significant customization for each platform. The one on Mig-29 is not going to be a drop in solution for Tejas! Unless you want to jam your own radar! The choice of the Elta radar and the Elta EW makes sure that it will work, and derisks the Tejas program.

Another simple point in the EW discussion is that the ones developed by DARE are internal EW kits. LCA does not have internal space for it !

The one from Elta is external pod.

It is as simple as that.

Yup, between left and right, the truth is always in the middle. JMO. There are trade-off reasons, we are not putting it on the analysis table, and perspective weight factors of decision authorities as well. None of the shaken-laws of the ddm world has the capability to table it correctly.

Also please consider the MK panel (PAC report on HAL) into your thoughts. HAL is trying hard to correct so many misdoings in one shot after a level-5 chabi. Why I am saying this, there may be added vigor in showing progress or corrections [logical].

Pappu has his share to fund these misadventures too.. he purposefully (guided by his dork sycophants) visited HAL, and vitiated the production folks against Rafale buy [another point - adding fuel to burning oil].

focus point is/was not technical here, but political.

Three things go hand in hand (very less scope of mix and match) - Radar, Radar 'inspired' AA missiles (all AA missile except the heat seeking ones) and EW. They all have to work in harmony and have to be deeply integrated.

Tejas fuel droptank put through test in Chennai - The Hindu
A team of scientists from the Fatigue and Fracture Laboratory and the Advanced Seismic Testing and Research Laboratory, CSIR-Structural Engineering Research Centre (SERC), Chennai, conducted a crucial qualification test of the fuel drop tank of the Tejas Light Combat Aircraft (LCA).

The laboratory designed and developed the test in consultation with the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Ltd. (HAL).

The LCA has been developed, designed and sponsored by the ADA and produced by HAL.

P. Gandhi, Chief Scientist and Head of the Fatigue and Fracture Laboratory, said the drop-tanks are attached to the aircraft externally and in case of emergency they can be de-linked and dropped, which gives them the name. The aircraft has other fuel tanks inside.

The 1,200 litre fuel drop-tank of Tejas needed to be qualified for sloshing of fuel when it is two-thirds full and vibrates during any air turbulence simultaneously as a mandatory requirement.

The test was carried out according to ‘U.S. Military Standard’ specifications and to prove that manoeuvring during flight would not be affected due to the sloshing around of fuel and additional vibration.

The tests were carried out using a specially fabricated test fixture, where a mechanical shaker mounted at the top vibrated the fuel tank to a specified frequency, and similarly, a computer-controlled servo-hydraulic actuator pitched it to an angle where the fuel would slosh.

Equipping the Tejas Mark 1A with Elta's ELM-2052 radar will ensure the fighter never carries the world-beating Meteor 'beyond visual range' air-to-air missile.

The MBDA, the European consortium that builds the Meteor, has repeatedly told the Indian Air Force that it would only fit that missile onto a fighter with a European airborne radar.

On October 26, the ministry of defence and the IAF watched from the sidelines as Hindustan Aeronautics signed two contracts with Israel Aerospace Industries which will condemn the Tejas Light Combat Aircraft to a marginal presence in the IAF's future fleet.

The contracts signed were for two major avionics systems that will determine the combat capability of an improved Tejas fighter called the Tejas Mark 1A.

One was for the ELM-2052 'active electronically scanned array' radar, developed by an IAI subsidiary, Elta.

The other was for Elta's 'electronic warfare' system.

Choosing an Elta AESA radar for the Tejas Mark 1A, therefore, rules out the Meteor and, with it, any hope that the IAF will buy the Mark 1A in significant numbers.
