Tejas MK1 has Indian radar, Foreign AESA is for only MK1A ..
Not really, the radar fitted on the Tejas Mk.1 is an Israeli EL/M-2032 radar modified to Indian specifications.
DRDO did build a radar in the late 90s but it was rejected due to compatibility issues with the airframe.

The coherent pulse-Doppler Multi Mode Radar is designed to operate equally effectively in the Air to Air and Air to Surface domains. Jointly developed as an Indian – Israeli venture, it features multi-target Air to Air Track, Hi Resolution Synthetic Aperture Mapping and specialised Air to Sea modes. The radar facilitates all weather employment of a variety of Air to Air and Air to Surface Weaponry, and is the primary targeting sensor on the Tejas.

====================





Tejas MMR ..

======
======



Uttam AESA for MK2 varient ..

-----------



Foreign AESA for MK1A in absence of Uttam AESA ..
ADA is now integrating Uttam AESA and DARE's EW suite on one of the LCA prototype. Aerial testing will conduct in coming months.
These trials will decide the future of AESA/EW suite tender.

ADA is pressurized to increase the indigenous content on LCA.

Fingers crossed , hoping for favorable results....

It talks about assistance not a clone or copy or modified & their is assistance and its specified at the highlighted part below in red ..

The original article is no longer working as its from 2007-8 source and being copied by other websites ..

The radar development was shown to be considerably more mature than previously thought. At Aero India 2009, it was revealed that the 3D MMR project has been superseded by the new 3D AESA FCR project led by LRDE. The MMR has been completed with Elta Israel's assistance involved Elta EL/M-2032 technology for Air to Ground mapping and targeting. This "hybrid" MMR has been trialled, validated and will be supplied for the initial LCA Tejas fighters of which 2 Squadrons have been ordered.
Multi-mode radar,a 3D radar is a HAL project of which DRDO's LRDE is a subsystem provider, this project to develop an advanced, lightweight Multimode fire control radar for the LCA Tejas fighter, has faced stiff challenges and been struck by delay. It has now been completed with Elta's (Israel) assistance. The multimode radar is a greater than 100 km range (detection of a small fighter target), 10 target track, two target engage, lightweight system.
It has been revealed that an all new combined signal and data processor had been developed, replacing the original separate units. The new unit is much more powerful and makes use of contemporary ADSP processors. The other radar critical hardware has also been developed and validated, however work remains on the software front. The software for the air to air mode has been developed considerably (including search and track while scan in both look up and look down modes) but air to ground modes are being still worked upon.

This series of tests are particularly aimed at testing the seeker of the missile. The seeker provides the missile guidance as it tracks and locates targets. The seeker being tested is a newly developed indigenous system. It is being tested for the second time, defence officials said.


“At least eight trials have been planned in this series and if weather permits, the tests would start from Thursday,” the official informed and added that the missile would be fired in a war-like situation.

Last year, the IAF had cleared limited series production of the missile and decided to obtain at least 50 missiles to gauge its performance before giving bulk order for its all fighter aircraft.

The missile tested during last December had successfully demonstrated its aerodynamic characteristics, repeatability, robustness and endurance capability. The IAF and the DRDO are also working on integrating the missile on light combat aircraft Tejas.

Astra BVRAAM integration work for LCA-Tejas to begin soon.
Astra has Mach 4.5 speed with 40G maneuverability. It has both LOAL & LOBL capabilities. While Chinese SD-10, mostly used by Pakistani jf-17 lacks LOAL capability.
This means we have access to the Elta 2032's software(source codes?) ...
Sweet!

In above link speed of Astra is 1.4 to 1.6 Mac and u r saying it's above 4 Mac. Which one is correct?

This type of no news is produced by IDRW without mentioning "when". Everybody knows that astra BVRAAM is meant for combat aircrafts in iaf possession such as lca Tejas etc. If it is ready than it has to be integrated to its intended platform at any time. Other than that what do you expect? Snoring in drdo lab table.

Single engine foreign aircraft will come the way the Rafale came. By stealth.

LCA will remain stunted at 120 tops and AMCA is already being delayed to ensure that it meets largely the same fate as the LCA

Each AAM is designed to exceed the speed of target.
And for ASTRA it is always 4+ Mach but the actual speed is bit more than what is stated in open sources.

Even knowing the current scenario of the competition, here contemplation has no meaning about choice. I will stick with the LCA and further more, even after a different choice is made I will make it a point not to project it as a Frontline fighter or an interceptor, knowing the full potential of the tejas and the time involved. The hard work and the lives lost in the project should let it be first choice.

Its better they should focus on FOC rather than testing this and that. This could done on later blocks after FOC

There are different teams doing different jobs.....Derby is already test fired .

FOC of Tejas will not be affected by testing and integration of astra.

Previously there were reports of issues with integrating Python with Tejas. Have they been solved?

9 months to build a jet, by this capacity when will we replace all the junk fighters from service?
We need atleast 20-25 each year to project power.
Chinese are mass producing the J-10 just like cars.
Mass production requires diversion of resources. When we are not likely to face war till 2030, why divert resources for ww2 type war production? Instead focus on developing infrastructure to enhance growth and earn foreign exchange to acquire ToT. Once all technology is obtained for 100% indigenisation, then mass manufacture by diverting resources mass manufacturing of tejas now needs Kaveri engine. If we import F414 engine at 8 million dollar a piece, 50% of aeroplane cost will go for that. Instead, first lets get Kaveri and then we can see

Money is for weapons imports or for indigenous R&D?

Make your choices Deshbhakton.
Muhammad Khagesh, please control yourself. Forex will only be used for ToT, not for import of finished product.

1) After 2018-19 the economy is going to pick up, right now it is growing at only 7%, another 1-2% will be added after 2018-19 easily.
2) Rafale is not 200m each, that is the cost inclusive of all training, infrastructure and customisations- the unit price the IAF is offered for the Rafale is arround $110m (around €85m- same as the French AF price).The marginal cost will fall substantially for the IAF for any fighter beyond the intial 36 ordered.
3) You fail to take into account the payback periods of large ticket deals- it is not a 100% upfront payment. In the Rafale's case it was 15% upfront and then installments over the course of 5-6 years. This will reduce the burden on the annual IAF CAPEX budget.

A nice analysis though bro but I'll stick to the fact that the SQN strength is going to be grow beyond 42 post 2027. But I really hope the GoI starts to address the dwindling allocation to the defence forces, since 2013-14 the spending (as a proportion of GDP) has gone from 2% to a historic low of 1.56% today.


It's absurd to ask the military to modernise with these restrictions plus given the increase in domestic defence production more defence spending would help stimulate the economy create jobs and further "make in India"
LCA's production can be ramped up by 50% (24/year) without adding ANY physical infrastructure by HAL.

IF IAF placed more orders for LCA than 123 units HAL would respond accordinly but they have set the 16/year target for 123 units so the line is open long enough for the MK.2 to be readied.


The only thing holding HAL back from churning out more LCAs is pitiful orders from IAF.
LCA must not be mass manufactured till we have engine. We are close to get an engine. So, why hurry unnecessarily? By 2019, if we can get 90kN engine, then we can make large number of LCA Mk1A till 2023-4 when we may get K10 100kN engine. After that, Mk2 may be mass manufactured.

If we look at USA or Russia, there is actually no limit on mass manufacturing scale if technology is indigenous. We can make 1 million jets too (if rhenium is available in that quantity) by simply hiring crores of people into assembly job.
