After long development path, BrahMos comes into its own

Air-launched version in testing; export interest from many countries

After entering modern warfare in 1944 as the V-1 and V-2 rockets that a desperate Germany fired into England towards the end of World War II, cruise missiles had a second coming as high-technology showpieces during the First Gulf War of 1990-91. The world watched television images of Tomahawk cruise missiles flying along the streets of Baghdad and precisely entering targeted buildings through open windows.

Yet, even the iconic Tomahawk cruise missile was effective mainly against incapable and weakened enemies like Iraq and Afghanistan. In contrast, countries with potent air defences and capable fighter aircraft can detect and shoot down cruise missiles, most of which fly at sub-sonic speeds, i.e. slower than sound, which travels at 1,224 kilometres per hour.

In contrast the Indo-Russian BrahMos, its name an intermingling of the Brahmaputra and Moskva rivers, is the world’s first cruise missile that flies at high supersonic speeds --- Mach 2.8, or 3,450 kilometres per hour. Since it hugs the ground, enemy radars can detect it only at short ranges. By the time they fire a missile to down it, the BrahMos is far away, perhaps already close to its target.

Last Saturday, India test-flew a potent, new version of the BrahMos --- a lightened missile that can be carried on, and fired from, the Sukhoi-30MKI fighter that is the backbone of the Indian Air Force (IAF) fleet. Transported on the Su-30MKI to the vicinity of the target, this overcomes the BrahMos’ one drawback --- a short range of just 295 kilometres.

This range restriction was imposed on the Indo-Russian missile by the provisions of the Missile Technology Control Regime (MTCR), which prevents member countries from transferring missiles, including unmanned aerial vehicles, which can carry a 500-kilogramme payload to a distance of 300 kilometres.

Russia is an MTCR member-partner; and India, which became a member-partner on Monday, has voluntarily adhered to MTCR guidelines since September 2008. While this imposed a 300-kilometre limit on the BrahMos’ range, there are no technological difficulties in increasing it. Both countries wave away enquiries about plans to do so.

With the BrahMos having carefully kept out of the MTCR’s purview, plans to export it are afoot. In May, the BrahMos Aerospace spokesperson, Praveen Pathak, told TASS: “talks [for the export of BrahMos] with countries like UAE, Chile, South Africa and Vietnam are in advanced stages.” He said discussions were also under way with the Philippines, South Korea, Algeria, Greece, Malaysia, Thailand, Egypt, Singapore, Venezuela and Bulgaria.

Including India’s own requirements of the missile, DRDO officials indicated that eventually $15 billion worth of BrahMos could be built for various militaries. If that happens, economy of scale would bring down the current high cost of the system.

A long development path

New Delhi and Moscow hold up BrahMos as their most successful defence project. It germinated in 1992-93, when India and Russia --- then in dire economic straits --- conceived the idea of co-developing a supersonic cruise missile. Russia’s rocket design bureau, NPO Mashinostroyenia, would develop the supersonic propulsion, while the Defence Research and Development Organisation (DRDO) developed the guidance and navigation systems and the command and control elements.

Sceptical of the DRDO’s capabilities, Moscow sent a team to evaluate whether it could actually develop sophisticated guidance systems. After carefully inspecting three DRDO laboratories --- Hyderabad-based Research Centre Imarat (RCI), which develops navigation systems; Defence R&D Laboratory (DRDL), which develops missile systems; and the Dehradun-based Defence Electronics Applications Laboratory (DEAL), which develops communications technologies --- the Russians agreed to the work distribution.

Yet, for long, the arrangement remained secret. In 1995, then DRDO chief, APJ Abdul Kalam, signed a preliminary agreement with Russia, after which Prime Minister Narasimha Rao, personally approved the project. This led to the establishment of the BrahMos Aerospace joint venture (JV) in February 1998 through an Inter-Government Agreement (IGI) between India and Russia.

AK Antony, then defence minister, told parliament on May 9, 2007 that Brahmos Aerospace has a share capital of $250 million, with India holding 50.5 per cent and Russia the remaining 49.5 per cent. While this paid for designing, developing, producing and marketing the basic BrahMos, the share capital was enhanced later by $50 million for developing the aircraft-launched version. This means India has contributed about Rs 850 crore at current exchange rates. The DRDO has spent another Rs 370 crores on developing Brahmos systems.

The missile burst into public domain with its first test-flight in 2001, which was witnessed by then defence minister Jaswant Singh, and all the service chiefs. What had been developed was a two-stage cruise missile, fired from a canister. The first stage, a solid-propellant engine, rapidly boosts the missile to supersonic speed and then drops off. The second stage is a liquid-fuel, air-breathing ramjet engine that powers the missile for most of the journey to the target.

Quickly realising its potential as an anti-ship missile, the Indian Navy offered two frontline destroyers, INS Rajput and Ranvir, to be fitted with the BrahMos. The admirals insisted it be capable of evading enemy missiles through complex manoeuvres, including right angle turns at supersonic speed. Later, the navy demanded a “salvo capability”, in which warships carrying the BrahMos can fire eight missiles at an enemy flotilla, two seconds apart, each targeting a different enemy warship.

With this achieved, the navy demanded a demonstration of these capabilities. In March 2010, INS Ranvir fire a BrahMos missile at a decommissioned vessel, INS Meen, which sank quickly after the missile slammed into it above the waterline. Since then, a satisfied navy has included the Brahmos in the arsenal of every Indian capital warship being constructed, including three destroyers of Project 15A, four of Project 15B and seven frigates that will be built under Project 17A. Even Indian warships built in Russia are fitted with the BrahMos.

The army too came aboard, given its need for precision firepower in implementing its new “Cold Start” doctrine, also referred to as “proactive strategy”. Given the differences in targeting, range and flight path, the army version of the BrahMos required a different configuration and software. A more precise guidance system was included in a new BrahMos series called Block II. The army then asked for a “steep dive” version for mountains, in which the BrahMos, after flying over a high ridgeline, could dive steeply to strike a target in the valley several thousand feet below. The complex changes needed in guidance software have been implemented in the Block III version. A satisfied army has ordered three regiments of BrahMos.

“We are entirely customer-oriented. Any programme that is not oriented to the customer will not succeed”, said K Sivathanu Pillai, the former director of BrahMos Aerospace.

Following the navy and army lead, the IAF has asked for two BrahMos versions. One is a surface-to-surface version for striking ground targets that are important for the air battle --- enemy radar and communications networks, and forward air bases. A second, lighter version of the BrahMos, its weight pared to 2.5 tonnes, will be carried on the Sukhoi-30MKI for deeper-lying targets. This involved strengthening the fighter’s airframe to allow it to carry a 2.5 tonne payload, and to ensure the missile does not impeded the flow of vast quantities of air needed to keep the fighter’s Saturn-Lyulka AL-31FP engines going.

With the missile having already flown on the Su-30MKI, the next step is to test-fire it to ensure the missile separates cleanly from the aircraft, after which its booster will ignite.

Also developed and test-fired in 2013 is an underwater-launched BrahMos, which can be fired from a depth of 40-45 metres. In the future is a “hypersonic” version of the Brahmos, which will travel at Mach 5-6.

On February 7, 2014, testifying to their confidence in the BrahMos’ future, India and Russia signed a document indefinitely extending the venture.

It is most surprising that that there are repeated claims of the Brahmos being the first supersonic cruise missile. Soviet Union/Russia had/have at least two, the SS-N-22 and SS-N-26 in their inventory for a long time, both supersonic. The Sovremennyy class destroyers supplied to the PLAN had these as standard equipment, so it is not unlikely that they have reverse engineered these. So both Russia and China have supersonic cruise missiles, and have had them for a long time..

Maybe I am mistaken, could some one care to clarify.

But the one thing I would like to point out is that its 290 km range hardly constitutes adequate standoff capability when deployed on Su30.In fact we also need the Nirbhay which has a longer range.It is high time also for the Air Force to acquire some long range heavy bombers like the Blackjacks which could be armed with Brahmos and Nirbhay together.This would empower us with real standoff capability.

The long running defense programs are finally giving returns that are visible. This is a very good achievement for our country.
The focus now needs to be on guns : infantry to artillery. We should hope that the locally developed 155 artillery leads to a Naval gun of the same caliber.

Sir, Any information regarding the BrahMos-Mini/BrahMos-NG

I am worried that China seems to have gotten an identical missile from Russia. I hope that they were given the basic Yakhont, and not Indian technology.

It is also possible that they are cyberhacking us. If they can rape 350 billion dollars a year from the US through cyberhacking, they can certainly attack us.

Brahmos vs Nirbhay
3000 kg vs 1500 kg (weight)
1000km/h vs 3500km/h (speed)
300km vs 1000km (range)

Brahmos takes 5mins to strike a target 300km away whereas nirbhay takes 20mins. Nirbhays takes a full 1 hour to reach its 1000km target. In simple words, brahmos is effective for use in moving targets. Nirbhay is useful for striking terrorist camps and non-moving enemy hideouts.

Oops, delete the last comment. Fixed the speed value mistake

Brahmos vs Nirbhay
3000 kg vs 1500 kg (weight)
3500km/h vs 1000km/h (speed)
300km vs 1000km (range)

Brahmos takes 5mins to strike a target 300km away whereas nirbhay takes 20mins. Nirbhays takes a full 1 hour to reach its 1000km target. In simple words, brahmos is effective for use in moving targets. Nirbhay is useful for striking terrorist camps and non-moving enemy hideouts.

An excellent missile system which provides great firepower. The Navy has done well to induct this on virtually every surface warfare platform. Artillery regiments with Brahmos would be very useful on the chinese frontier

Why restrict it su30 why not transport fleets. They can a lot of them if needed.
