Brahmos missile flies on Sukhoi-30, IAF moves towards deadly new capability

With the successful test flight on Saturday of a Sukhoi-30MKI fighter fitted with a Brahmos cruise missile, the Indian Air Force (IAF) has moved closer to a potent new capability.

When the Indo-Russian Brahmos is operationalized on the Su-30MKI, IAF pilots would no longer have to fly deep into heavily defended airspace to strike enemy fighter bases, or targets like terrorist camps, nuclear installations and military headquarters. Instead, they can launch a Brahmos from as far away as 295 kilometres, and turn back to safety while the missile flies on to do the destruction.

Business Standard learns the IAF will modify at least 40 Su-30MKI fighters to carry the Brahmos missile.

Air-launched land-attack missiles are not new, nor are cruise missiles like the vaunted US Tomahawk missile, that can be launched from thousands of kilometres away. What makes the Brahmos-Su-30MKI combination lethal is the speed with which it strikes --- the aircraft flies well above Mach 2, and the missile flies at Mach 2.8, giving enemy air defences little chance to detect and shoot them down before they strike the target.

Besides eliminating the need for taking a human pilot over heavily defended targets, the Brahmos has also proven to be a highly accurate missile. For the IAF, getting Hindustan Aeronautics Ltd (HAL) --- which builds the Su-30MKI under licence at Nashik --- to integrate the aircraft with missile has been a priority.

On instructions from Air Headquarters, Sukhoi (in Russia) and HAL (in India) independently conducted feasibility studies. After the IAF determined that HAL had evolved the simpler, most manageable, design, it placed an order on HAL in January 2014 to integrate the Brahmos onto the Su-30MKI.

“It is a perfect example of ‘Make in India’ and an engineering marvel in aviation history of India. It proves that when all agencies come together with one mission, there is nothing like impossible”, declared the HAL chief, T Suvarna Raju, after the flight test today.

Business Standard was granted exclusive access to the Brahmos upgrade, while HAL was carrying it out at a facility called the Aircraft Upgrade R&D Centre (AURDC) in Nashik.

The AURDC had earlier upgraded the MiG-27 and MiG-21 fighters, partnering a Defence R&D Organisation (DRDO) laboratory called the Defence Avionics Research Agency (DARE). Along with DARE, the Indian Institute of Technology, Mumbai, also played a part in the Brahmos upgrade.

A key challenge was to strengthen the Su-30MKI airframe, particularly its underbelly weapons station, to carry the huge Brahmos missile (8 metres long, 0.7 metres in diameter, and 2560 kilogrammes in weight).

Since the Brahmos protrudes beyond the Su-30MKI’s air intakes, it was imperative to ascertain that it did not impede the flow of air into the fighter’s engines. This was achieved through computational fluid dynamics modeling.

Meanwhile DARE modified the pilots’ digital cockpit display, creating a new “page” that the pilots would use while launching the Brahmos.

Having established that the Su-30MKI can carry the Brahmos in flight, the IAF will now carry out flight-testing to determine the penalty such a bulky external load imposes on flight parameters like speed and turn performance.

After that, the IAF will actually fire the Brahmos from the aircraft, ensuring that the missile separates from the fighter smoothly. This phase of testing will also check how accurately the Brahmos hits its target.

The Su-30MKI is already a highly modified aircraft, with HAL having carried out more than 40 modifications to the fighter originally delivered by Russia. It is expected that countries like Malaysia, which fly a similar version of the Su-30, could also seek the Brahmos capability.

Sounds like they have no wish to fight a conventional war.

Anyhow, the ABM program itself is expensive and its success rate limited. Not many countries invest in it. I'm very sure these brahmos sukhois will be pointing to the eastern front.

Can you do a summary post on the chinese building their submarine front aimed at indian coasts. This is the emerging situation.

Good move by IAF. It had the foresight first to seek out special editions of of the Sukhoi fighters, then ensure they are locally made. Now this capability being added locally through HAL.
Let us hope the testing goes as per schedule, it should add a lot of muscle power to IAF's heavy fighter fleet.

SU30 MKI as per drdo was supposed to carry 3 brahma missiles each. Now we see only one on SU30? Will it ever carry 3 missiles?

Excellent. Well done indeed. Having modified the Sukhoi-30 to integrate with Brahmos, we now need to modify our PM and Defence minister to integrate with the war making potential of India. Else, this is waste of good money which India does not have too much of it. Modifying the top decision makers of Indian defence will admittedly be a more difficult job.

Hello Colonel,

Think of India increasing the range of Brahmos to 1000 KM, now that India is part of MTCR, and Sukhois firing those into Chines cities ... I mean fully loaded. India does not need B-52 bombers ... that will be good fun...

Good news but still waiting on the update of FOC of Tejas and IJT...can you please provide an update on them?
