EXCLUSIVE: How A Secretive DRDO Lab Is Saving The IAF Su-30MKI


DARE scientists Suneeta Awasthi Singh, Durga Prasad and Regu Kumar at their Aero India stand.

India’s Defence Research & Development Organisation (DRDO) has a rough time dealing with a reputation for waste and delays. To be sure, most criticism it faces is justified. Which is perhaps why it’s always heartening to hear about success. Scientists quietly working behind the scenes on small projects that are truly contributing to the lofty ideal of self-reliance. The story your correspondent reports on today isn’t doing just that — it’s also set to save the Indian Air Force precious capital going into the future.

It all begins with the Russian SAP51A jammer pod that Moscow supplied with the Su-30MKI. After grappling for years with the pod, the Indian Air Force finally in 2015 realised it simply couldn’t use them for two reasons. One, they were heavy — and when slung onto wingtip hardpoints, they cut into flying envelope like a butcher’s knife.

‘With the Russian pods, the Sukhoi is basically a transport aircraft,’ one of the scientists says.

The second issue is even worse. The IAF realised the SAP51A pod hadn’t been properly interfacing with the indigenous on-board radar warning receiver (RWR), therefore killing pilots’ chances to exploit both systems fully. While the reasons why the IAF took their time remains unclear (but at one level understandable), DRDO’s Defence Avionics Research Establishment stepped in immediately, offering to help. The result is the pod you see those three scientists standing next to in the photograph above.

DARE’s High Band Jammer (HBJ) pod begins dummy carriage trials in six months on an IAF Su-30MKI, with full integration within the year. By 2019, DARE has committed to seeing the pod become fully operational with the IAF’s Flanker fleet.



Significantly, the HBJ pod will be a fully indigenous one. A DARE scientist explains that the HBJ pod currently has three major systems: the integrated EW suite, the active array phased transmit-receive unit and the cooling system. While the first two have been rapidly developed in-house, the complex cooling system is in process, with DARE sourcing an Israeli system for the moment. The team says they’ll have a fully functional Indian cooling system on the HBJ pod before full integration trials by the end of the year.

Better still, the HBJ pod, the scientists tell Livefist, will spawn a family of EW sensors and systems for platforms like the LCA Tejas, MiG-29 and any other fighter the IAF chooses to operate.


The Indian Air Force, which has embraced the wares from DARE more than kit from most other DRDO labs is expectedly thrilled. An IAF Su-30MKI pilot at the show confirmed that the HBJ pod was a ‘very promising system’ and that ‘more than anything, it is our own in-house development, so I don’t have to run to the Russians if something doesn’t work’.

A DARE scientist associated with the project tells a familiar story: Russia’s unwillingness to share codes (or its insistence on an additional commercial understanding) that could have helped manage the interfacing issues between the SAP51A pod and Indian RWR better and faster.



Incidentally, the indigenous DARE RWR on the IAF’s Su-30MKIs will also be replaced soon. The lab is in final testing of an all digital RWR (the existing system is analog) christened ‘Dhruti’ that will begin ground testing in May this year, followed by a phased installation across the fleet.

DARE is one of the DRDO’s most low-profile laboratories and also one of its most successful. Its systems populate virtually every combat aircraft currently in service, including missile approach warning systems, mission computers and avionics of every kind.

A final little flourish from the unassuming DARE stand at Aero India is the SIVA pod, a development from the nineties that didn’t quite work out and was quietly abandoned. Recently, scientists dusted out from the corner of a DARE warehouse when a team of scientists suddenly realised they could help the people at BrahMos save a penny on testing the airborne seeker on the BrahMos-A.

With the new DRDL-led imaging and monopulse RF seeker (IMR, for a future variant of the BrahMos) fitted into the Siva pod in a matter of days (the DRDL had tendered out for the integration process), the pod was quickly slung onto a Su-30MKI and sent up for the required airborne tests. It was an immediate success, with BrahMos Corp. sending a special word of thanks to the DARE team. Without that flash of brilliance from DARE, BrahMos would have had to hot-step it to Russia or elsewhere to get a testbed. And the Siva pod would have forever remained a failed relic from DARE’s early days. Instead it is now a valuable, cheap test-bed for high-performance systems.


‘Now we have a very capable in-house testbed capable of testing a variety of electronics and systems in the airborne regime. This is the beginning of a testbed capability that is normally very expensive to hire. It will be finetuned and evolved before being offered as a full-fledged service, perhaps even to foreign customers,’ says a DRDO officer.

Good, we should make a target that by 2028-2030, everything from A to Z should be made at home. No dependency on russia or any other country. Be it fighter, copters, own designed guns,radars,tanks,warships, subs, everything should be made here only. I want to see our navy 3.5 times big as it is now by 30, and indigenisation is the only way to go. We will get more value for money, better quantity, also no hassle/negoniation with any one. No dependency in war time. More investment should be done in RnD and pvt players should be encouraged. But, be wary of sabotage from Unkil sam/rus or chinis, like they have done before.

The article mentions that the Rafale will be the first IAF fighter to have MAWS. However:--

Also, from what I can find on the net, DARE has been making MAWS from around 2015; for the ALH and the AEW aircrafts. So I am hoping that our fighter fleet is also MAWS equipped??

@kunal1123 @smestarz @Alok Arya @HariPrasad-1 or anyone who can clarify.
I appreciate any info on the the subject.

DARE produces MAWS but that is mainly for ALH and other Indian projects, Most (almost all our fighter planes) are having MWS (Missile warning system) MAWS was available when IAF was modifying Su-30 MKI for its use, but seems they deemed they did not need it, Su-30 MKM (Malaysian version) has MAWS. Where as IAF deemed that MWS is enough

What is the mouse doing in the cockpit. Is just for some sort of simulation or it really is part of the Super Sukhoi o_O
It is used as a track pad to select different options. This is most likely Su 30mki not super sukhoi as super sukhio will have touch screen

however, there are other tricks in the book like the kulbit etc. are they useful for any engagements? and if so, are they practiced by the IAF despite the potential stress on the airframe?
I am posting here so that the discussion does not go off topic in the other thread:


The loop/tumble/yaw as they are calling it seems similar to the kulbit. If an aircraft can perform this, it would place our aircraft behind the pursuer and does what a cobra does in a combat pursuit situation.
Also the TVC MKI can sustain slow speed slides with + AoA (video 1.55 onward) and tighter turns / yaws. I think this should be a bigger advantage than a momentary cobra in a dogfight.

They might have stopped with the aerobatics due to the low serviceability that was prevalent.

There is a video of a Su-30 (with canard) doing a cobra, but not sure if it is IAF. Low quality video.

was looking at video of Russian Su-30 SM
Awesome video and its awesome because it does all those maneuvers (like Cobra) being armed,
That shows that such a maneuver can be done during actual A2A combat

First of all thankyou very much for posting this beautiful pics.
I have a question for you.
People here are talking how india squandered millions of dollars in fgfa.
I want to know from you has india really invested money untill now in this programs such as pakfa or fgfa with russia or only talks are as usual going on.

We have already spent 50 Million $ for the design phase of the FGFA

India's enemies nervous as Sukhoi-30 MKI-BrahMos integration gets closer to reality



New Delhi: If everything goes as per plan, the Indian Air Force (IAF) is all set to become the only air force in the world with a supersonic cruise missile system!

India will achieve this unique capability when IAF's frontline fighter aircraft Sukhoi-30 MKI will test fire a 2,500 kg BrahMos air-to-ground missile in the coming months. Some reports have claimed that the test firing will be held in April.


The IAF had, last June, flown with a 'dummy bomb' and had been preparing for the actual test firing since then.

With a range of over 290 kms, the BrahMos, onboard the Sukhoi-30 MKI, will provide the IAF the lethal capability to strike deep inside enemy territory without the risks involved in entering a heavily defended airspace.

Integration of BrahMos with Su-30 MKI will render the weapon a multi-platform capability, allowing the IAF to deliver a deadly blow to their vital installations from stand-off ranges.

The integration brings a paradigm shift in the capability of the IAF vis-a-vis its adversaries.

The Su-30-Brahmos combination will carry out air combat operations within and beyond visibility range and will provide the IAF with the capability of attacking targets protected by powerful air defence assets.

Around 40 Su-30 MKI aircraft are expected to be modified to make them capable of carrying BrahMos.

As per reports, several other countries in possession of the Su-30 strike fighter are looking to acquiring a lethal weapon system for the Russian-made warplanes.

What about using composite materials to reduce dependence on titanium from russia ,and also improving performance ?

It is planned in the upgrade, plus it depends which composite are selected and do we have the production for it

Are there any plans to developed conformal tanks for the su 30 mki , and are they even feasible on the su 30mki
Take a look at this pic (I guess its a representation and not a real image ) of the su 27 . and does the I Indian air force really need such tanks for their mki s ? It would be good to know

No plans to develop such conformal tanks for Su-30MKI
But such type of tanks are recently developed for RAFALE and tested successfully without any aerodynamic hindrance and change in performance and will be offered to IAF

Using conformal tanks has its penalty, basically there is penalty of weight and drag. The moment you add something to the plane, may it even be a missile, it will have penalties in performance. but the shaping and position of the CFT is such that the impact on performance is as less as possible,
Just a thought, if there is no penalty in terms of performance by adding CFT, why does France not use them? They have carried out deep strikes in Africa and they have used Drop tanks, as recently as a year back.
Su-30 MKI has big internal fuel tank that is enough for it to do air policing, Adding CFT will improve the range but at cost of performance.

The penalty of CFT is you can't drop them when empty. In all other regards it is the superior option.

As I mentioned in my previous reply that these CFTs won't require dropping when empty.
And no drawbacks in reference to aerodynamic effect
