Well ithink Mk-3 might come with some advancements in then currently operated aircrafts.....
 
.
1. MMR + EL 2032 for MK-1 & MK-II EL-2052 AESA
2. 4000 kg with 3000 Internal fuel capacity.
3. Ioc clear 2010-2011 Ist 40 MK-1 & then2013-2014 Foc from the latest new 100+40 to be built mk-II standard

Thanks Sudhir

Kind of interesting news, why a coop with Volvo? They might have experience sure, but has no own engine at the moment in their fighters.

Indigenous technology for Tejas Aircraft

The engine used in Tejas Aircraft is imported from USA, whereas 70% of avionic systems integrated on Tejas is indigenous and 30% has been imported from Israel, France, Italy, United Kingdom and USA. Parallel efforts are being made for indigenizing remaining 30% of the avionic systems.

Only few countries in the world are currently capable of design and development of engines for aircraft and tank. These are exceptionally complex technologies and involve many disciplines and vast industrial base and capabilities. Hence development of these technologies take longer time.

Indigenous Kaveri engine development program for the Tejas aircraft is already under progress. To cater to the additional thrust requirement within the same engine envelope, co-development with an established and reputed international engine house is being contemplated.

IAF wants EJ200 engines for Tejas, but..

Bangalore: The geopolitical factor that determined state-owned Air India's choice of commercial aircraft in the mid-2000 may come into play again in the Indian government's selection of engines for its indigenous light combat aircraft (LCA) Tejas.

In 2005, when the national carrier's order for 50 aircraft worth $6 billion went to US aerospace company Boeing, its French rival Airbus Industrie had said it was the "geopolitical factor" that had clinched the deal.

DNA Money has learned that Indian Air Force (IAF), which is the user of LCA Tejas, has in its recommendations to the Ministry of Defence favoured the purchase of European aerospace company Eurojet's EJ200 over US aerospace firm General Electric's F-414. These are the only two companies that have bid for the $750 million order for 99 engines.
An IAF official, who did not want to be named, said IAF want the EJ200 to power Tejas so that there is no delay in building the LCA with enhanced power. The government is currently carrying out technical evaluation of the two military aircraft engines.

"The thrust of EJ200 (about 85+ kilonewton) may be slightly lower than F-414 (95+ kilonewton), but it will easily fit into the LCA. And if the weight is reduced, its (EJ200) power will be adequate. Thus, we will not have to change the design of the fuselage," the official said.

The official said since the F-414 was a "fatter" engine with a bigger diameter, it could require redesigning of fuselage. "And if that happens, then all the test flights, many of which have already been carried out, will have to be repeated and the whole programme could get considerably delayed. It will also escalate the cost."

He, however, said the price of the European engine was higher than the American engine. "Generally, aircraft equipments bought from US are cheaper because of their scale of production. European manufacturers do not have the same volumes and so tend to be expensive," he said.

But even though the IAF is pitching for the EJ200, the final decision would be made by the Ministry of Defence with inputs from the Aeronautical Development Agency (ADA), Hindustan Aeronautics (HAL) -- the state-owned company that is manufacturing the aircraft -- and Defence Research and Development Organisation.

A defence analyst, who did not want to be named, said looking at direction of the winds in the Indo-US relationship, which is very positive at the moment, the aircraft engine deal could well fall in the lap of the US aerospace company.

He said the order for F-414 would also work in favour of HAL and ADA. "It (F-414 order) will mean more money and work for both of them (HAL and ADA) as the aircraft require redesigning. This way we will get more business. Everybody is trying to push their own agenda," he said. "My guess is that F-414 will be thrust upon the IAF despite the fact that they want the EJ200 because Americans are pushing hard for it."

The two major aircraft and engine manufacturers are aggressively lobbying for the engine deal because its outcome will have a bearing on India's order for 126 medium multi-role combat aircraft (MMRCA) worth over $10 billion.

"The government is likely to go for aircraft, which is powered by the same engine as Tejas. One argument is that if these fighter jets come in time, then any delay in the Tejas programme will have less significance on the IAF," said the analyst.

well sadly, this is the end of all hope for Rafael.

Given at this rate, we might get a MMRCA winner soon.

First of all the Title of the thread is misleading!

Secondly, a 10+kN thrust is of tremendous advantage in a combat aircraft. Therefore, nothing wrong with the selection.

The author says that the F-414 engine is "fatter" requiring considerable redesigning of the Tejas' 'interior'. BS!!! The tejas already uses the GE F-404 engine for now and the F414 is just a modified version of it.

here are the specs for these engines:

The EJ2000 is apparently 6in smaller in diameter. However both the GE engines are 35in in diameter. Pray then how is the F-414 "fatter" than the F-404 which presently powers Tejas?

Its BS that the IAF is heavily recommending the EJ engine! The author also quotes a person as saying that the EJ costs more, is underpowered compared to the GE engines and requires redesigning of the internal fuselage. And inspite of this, yet says that the GE engine is being thrust upon the IAF which apparently wants the lesser EJ engine?

Geez, do a little research about the topic before you decide to post new threads!

First of all the Title of the thread is misleading!

Agree with you totally. The original article was published by Parveen Sharma in BR on 05 Dec and in Asian Def on 06 Dec. Would be enlightening to get his clarifications on this article.

well sadly, this is the end of all hope for Rafael.

Given at this rate, we might get a MMRCA winner soon.
Why? There is no French engine on offer for LCA, so that can't have an effect on Rafale at MMRCA.
Also I have some doubts about how reliable the article is, because there were enough false articles before refering on:

An IAF official, who did not want to be named

or:

A defence analyst, who did not want to be named,

Also EJ 200 that powers EF has 90kN, not 85, GE 414 that powers F18SH has 98kN, not 95. LCA don't need a redesign because GE414 is
a "fatter" engine with a bigger diameter
, but because the engine needs a bigger air intake similar to the changes from F18 Hornet to Super Hornet. As far as I know, the diameter of the 414, is the same as the diameter of the 404 actually in use in the LCA MK1.

However, if we compare both offers just with the best for LCA in mind, there can't be any other choice than the EJ 200! Around 95kN thrust, less weight and TVC, in combination with Astra missile, AESA radar, low RCS and delta wings could make LCA MK2 to a first class interceptor!
With these benefits and more ToT that is on offer, it clearly also pays back the higher costs!

Adding one more think that Navy also want navlaise version but ej200 is not tested in sea environment or you can say salty water condition if we want we need to bear on ourself and give some money and for this it will talk time consuming mean more delay more costlier. but ge414 already tested ...
