Finally, Tejas gets electronic warfare systems

After eight years of research and postponement, India’s first indigenous light combat aircraft (LCA) Tejas, positioned at HAL Bangalore, has finally been fitted with electronic warfare (EW) systems.

Now, new test flights will happen with electronic warfare anytime during November or beginning of December. The 2,348 test flights of the LCA so far have not had electronic warfare. The new test flights will bring in new data and information for further development of the aircraft and the electronic systems.

Sources in the Defence Research and Development Organisation (DRDO) told Deccan Herald that the LCA Prototype Vehicle-1 (PV-1) has now been fitted with a radar-warning receiver, a radar-warning jammer, laser warner, missile-approach warner, emitter, and a flare dispenser. The systems are now undergoing ground trials with aeronautical engineers simulating multiple threats to the aircraft and then examining its response.



The results of the ground trials will help fine-tune the electronic systems for the actual test flights. The ground trials will take about a fortnight or a month. So, test flights will be held in mid-November or December.

Engineers and scientists working on the project say the radar receivers and jammers will track enemy signals from air and ground, while the emitter will watch out for missile launches from ground. Systems to track missiles from air and enemy aircraft will also be part of the LCA. The entire system has been developed by both Indian and Israeli engineers and scientists.

The fitment of the electronic systems has an interesting history. For almost eight years, a section of the aeronautical community has been resisting its fitment, anxious that the add-ons may cause a first crash, which has never happened so far in the LCA’s test-flight history. They have been very keen on securing the operational clearance, initial as well as final from the Indian Air Force, even if the LCA did not have the electronic system.

Their reasoning was that once the IAF certified it as operationally worthy, they would have a successful product to showcase to the world. Also, the LCA has had a perfect record of test flights and no one wished to risk an add-on on the LCA that had not been tried. The idea was to defend the ‘zero crash’ record.

This was made known sometimes explicitly to engineers and scientists working on the electronic systems, who, however, had been pressing for very long that the systems ought to be fitted and trials conducted to be able to fine-tune them. This difference of perception on the LCA persisted for long, and one consequence was, no vehicle or version of the LCA was identified for many years to fit the equipment. This caused delay of over five years in launching the electronic systems on the LCA and to questioning of the very purpose and objective of building the systems.

After haggling for over eight years, it has been finally decided to instal the electronic systems on the LCA prototype Version-1. But there’s a catch here. The PV-1 has not flown for very long and has been parked in the hangar with later versions of the LCA undertaking the test flights. The PV-1, which began flights in around 2001-02, has completed 242 test flights after which it has been grounded. Now, there is a bit of anxiety about how an aircraft that has not done flights for long will perform with the new electronic warfare systems.

The confidence, however, is that the aircraft may perform well because its health has been under check almost daily and every department concerned will certify that all parts of the aircraft are flight-worthy. Without this certification, the PV-1 will not be allowed to fly. But once it passes the certification, the LCA PV-1 will become the first vehicle to fly with electronic warfare systems.

Is the EW system In house or Foreign
LCA was supposed to have the indigenous Mayavi EWS though I'm not fully sure if this has changed.....Anyway we are fully capable of producing an indigenous EWs and I think our Mig-27 have an indigenous EWS
The features of Mayavi are as follows:
FEATURES:
1. It will have Radar Warning Receiver to detect Radio waves. This will notify the pilot when he is being engaged by either radar lock or missile attack.
2. It will have Self Protection Jammer for radar deception. This will jam ground based radars, on-board radars and incoming missile by interfering with its radio frequency.
3. It will have Laser Warning System to detect laser emission of laser guided weapons.
4. It will have Missile Approach Warning System which will automatically detect incoming missiles of all types and warn the pilot.
5. It will have a standard chuff/ flare deployment system which is common on most fighter today.

Advantages are many fold
Firstly the DAS1 ( Defensive aid suite one) on LCA and current MKi is Federated and not an integrated one .
- First thing that MAYAWI brings is Integrated DAS
- CMDS will be tightly coupled with TMS core computer
- Mayawi will have its own SPJ in contrast to discrete EL/8222 jammer, EL82222 which is not part of DAS of LCA or MKI
- Currently both LCA and MKI lack ELS , MKI currently carries SIVA pod for Emitter location and subsequently guidance to KH31-P missile . Not sure what such system is on-board LCA to give SEAD/DEAD capability
- Mayawi in addition will add
LWS
MAWS
TAD

This is only little bit of information available about Mayawi , specs and operating freq, range all are classified

All the stuff that Mayavi provides seem to be basic, must-have requriements for any fighter (chaff dispenser, RWR, etc). If this is the first time LCA is getting an EWS, what did the earlier versions carry? Were they equipped with a different EWS, or none at all?

Possibly nothing or may be it is possible that it had some individual component of this EW suite(like flairs and chaff dispensers) but not as a fully integrated system.More knowledgeable member can throw some light in this regard

No complete system at least, since LCA is still only in prototype stage. Testing the fighter itself and with every new step more systems is the aim, the problem is only, that we wanted too much own developed systems, which delayed things too long. That's why radar or EWS will be integrated now only, while the of the shelf HMS, or LDP were integrated years ago, which normally goes the other way around in every normal fighter development.
 
Actually, without Russian assitance. LCA will never get to fight in the air. Right now it has no hope. :( While JF-17 numbers have increased from 150 to 200-250. Thats what you call a successful aircraft.

Without Chinese assistance, Pakistanis could not even imagine how to design an airpane. The condition of Pakistan's aerospace industry can be understood by the fact that they need Chinese rockets to launch basic satellites.
 
Great news drdo and Hal may pull this off yet. Cant wait to see tejas in full sqaudron service along side mirages and mki
