Astra Air-to-Air Missile is a major indigenous success for India

On Friday, the defence ministry announced the successful development of the most challenging missile India has developed so far – the Astra. Fired from a fighter aircraft travelling at over 1,000 kilometres per hour, the Astra destroys an enemy fighter 65-70 kilometres away.

According to the ministry, the latest round of trials conducted off the Odisha coast on September 11-14 saw seven Astra missiles fired from a Sukhoi-30MKI fighter at pilotless aircraft that were designated as targets. All seven Astras hit their targets.

This round of tests “has completed the development phase of the [Astra] weapon system successfully”, stated a defence ministry release on Friday.

Defence Minister Nirmala Sitharaman congratulated the Defence R&D Organisation (DRDO), which developed the Astra; Hindustan Aeronautics Ltd (HAL), which integrated the Astra onto the Su-30MKI fighter; and over 50 private firms that participated in building the missile.

The Astra – designated a “beyond visual range air-to-air missile”, or BVRAAM – involves radically different technology challenges compared to ballistic and tactical missiles. For one, a typical Astra engagement has both the launcher and the target moving at speeds in excess of 1,000 kilometres per hour.

Fired from a pylon on the wing of a Su-30MKI fighter, the Astra’s smokeless propellant quickly accelerates it to about 4,000 kilometres per hour, as it screams towards its target. The Su-30MKI tracks the target continuously on its radar, and steers the missile towards it over a data link. About 15 kilometres from the target, the Astra’s on-board radio seeker locks onto the target; now, it no longer needs guidance from the Su-30MKI. When it reaches a few metres from the enemy fighter, the Astra warhead is detonated by a “radio proximity fuze”, spraying the target with shrapnel and shooting it down.

Only a handful of missile builders – in the USA, Russia, Europe and China – have mastered the technologies that go into air-to-air missiles. India is now joining that elite group.

Ultimately, a fighter aircraft is only as good in combat as the missiles it carries. An aircraft can close in with an enemy fighter and position itself dominatingly. But, eventually, an air-to-air missile must shoot the enemy down.

The Astra is fired from the Russian Vympel launcher – a rail under a fighter aircraft’s wing from which the missile hangs, and is launched. The Vympel launcher is integrated with all four of India’s current generation fighters — the Su-30MKI, MiG-29, Mirage 2000 and the Tejas – allowing the Astra to be fired from all of them.

Astra components that have been developed indigenously include the missile’s propulsion system, its on-board computer, inertial navigation system, the radio proximity fuze, and data link between aircraft and missile.

Even so, the missile’s seeker head – a key component of most tactical missiles – is still imported. This is a key development thrust for the DRDO.

On the drawing board is a longer-range Astra Mark II, intended to shoot down enemy fighters up to 100 kilometres away.

According to the defence ministry, the latest Astra tests included engagement of long-range targets, high-manoeuvring target at medium range and launches of missiles in salvo to engage multiple targets. Two missiles were also launched in the combat configuration with warheads.

With the Indian Air Force operating 600-700 fighter aircraft, there will be a need for several thousand Astra missiles. With air-to-air missiles costing in the region of $2 million each, the Astra will provide major business opportunities to Indian firms.

i am not expert but as my little brain know there are two ways
free fall bombs or guieded bombs were tighted with hard point and released
and missiles attached and button pressed to be activated and realesed on rail .
you can seer rail and in center a connection for launch

Pylons either operate on a rail or hook type

In bith cases, the trigger releases any hook,clasp or otherwise holding the weapon on- in the case of rails- the missile is free to slide away.

The trigger also sends any signals to activate the weapon for its launch guidance and other functions designed for it post aircraft
 
Sky is the limit for cruise missile
Given the many merits of cruise missiles, the test-firing of BrahMos-A must adhere to the timeline announced as it will open up avenues for India to acquire state-of-the-art technologies

The supersonic BrahMos cruise missile air launch version (BrahMos-A) will be test-firing by the end of this year. This was disclosed by the Air Force chief, Air Chief Marshal BS Dhanoa at the customary media interaction on October 5 to mark the Air Force Day.

With this test being successful, the air launch version would enter the Air Force, completing the trio of the anti-ship version with the Navy and the land-attack version with the Army. It is important that this test, preparations for which have been made since 2012, be held on time as it would initiate induction of technologies critical for cruise missiles, which would be the game-changers for deterrence and war-fighting.

A single BrahMos-A fired from the Su-30MKI aircraft will witness a 300kg warhead going at speed of 2.8 Mach, hitting a Naval target (an abandoned ship) at 400km range with pin-point accuracy (zero Circular Error Probability, or CEP) with the radars of the Defence Research and Development Organisation (DRDO) recording the entire event. It could be argued that what is the big deal if the Su-30MKI flying close to Mach 2 speed with a range of 3000km and payload carrying capacity of 8,000kg (eight tonne) is used to throw a single BrahMos-A missile onto the sea-target? The big deal would be that with zero accuracy error, BrahMos-A would provide excellent stand-off maritime strike capability and lethality when launched from air close to Andamans and Nicobar Islands (where India has the Andaman and Nicobar Command) to cover the Strait of Malacca, the key choke point that connects the Western Pacific with the Indian Ocean. India, thus, would have acquired the capability to both seek (through its P-8I aircraft) and kill hostile vessels entering what it considers its backyard where the Indian Navy is the net security provider.

Moreover, this would be just the beginning. The next step would be simultaneous work on three fronts: Equipping 40 Su-30MKI with this capability; miniaturisation of BrahMos-A to BrahMos-NG (Next Generation), work on which has begun with Russia and is expected to be accomplished by 2021; and indigenisation of two key technologies — propulsion and seeker — which will have a wider application in the sub-sonic Nirbhay cruise missile, which being built by the DRDO, is at present, not much of a success.

The radar, seeker and propulsion technologies of BrahMos-A come from Russia. It uses a mono-pulse X-band Imaging Synthetic Aperture Radar which is better than the Terrain Contour Matching (TERCOM) radar used in cruise missiles the world over. All cruise missiles flying at sub-sonic (less than sound) speeds are designed to be terrain-hugging since they are required to evade enemy radars by flying low over large distances. Given this, they have TERCOM, which continuously maps the terrain and matches it with its own stored data to reach the target.

Since BrahMos is the only cruise missile with super-sonic (more than sound) speed, it travels at about 16km above sea-level. It uses this special radar which gets its updates from the GPS/Russian Global Navigation Satellite System or GLONASS and flies across many way-points (where the flight changes its path instead of the traditional trajectory which can be monitored) to evade enemy radars. Because of this peculiarity, and the super-sonic speed, BrahMos is impossible to be intercepted.

The BrahMos seeker — seeker SGH — is made by the Russian company, Granite Joint Stock Company. It has the capability for accurate terminal guidance, where the seeker takes over from the GPS supported radar to hit the target. The DRDO is developing an indigenous seeker, which involves numerous domestic companies, especially Data Pattern and ECIL. Once done, the seeker will be an Indian IPR design which can freely be used in other applications. It is for this reason that the DRDO did not take up the European MBDA company’s offer for transfer of seeker technology as part of the, now abandoned, joint-development and production Maitri short-range surface to air missile programme.

The BrahMos propulsion involves two-stage motor, of which the booster is the first stage and the ramjet engine (much better than turbojet technology) being the other one. In order to reduce the weight of the BrahMos-A by 500kg as compared with the Navy and Army version of BrahMos, the booster size has been reduced with the ramjet engine remaining the same weight. This has been done since BrahMos-A fired from the Su-30MKI will already be at an altitude that does not require much boost to enter the cruise phase powered by the ramjet engine.

The challenge, however, will be in the miniaturisation of BrahMos-A so that three missiles — BrahMos NG — instead of the present single missile on the Su-30MKI can be loaded. This will require a new ramjet engine, work on which is underway with Russia. In terms of war-fighting, Su-30MKI armed with three BrahMos-NG will enhance the Air Force’s mission options.

This is not all. Once India gets its propulsion and especially the seeker, it will be a big boost to the other DRDO programme — the sub-sonic Nirbhay cruise missile. This missile has had four tests, out of which three were unsuccessful and the results of the fourth were not disclosed. The Nirbhay is claimed to have 1,000km range with a turbofan engine. Turbofan engines consume much less fuel than turbojets of equivalent size; hence are more complex system and extremely expensive. Accordingly, turbofan engines are considered suitable for long-range cruise missiles with ranges between 600km to 2,000km. At present, only a few countries have mastered the turbofan propulsion technology. Interestingly, China is amongst them and Pakistan’s Babur cruise missile uses Chinese technology.

In fact, the Nirbhay programme was started to meet the challenge from the sub-sonic Babur missile. A few turbo-fan engines were procured from Russia. However, when the DRDO openly boasted about Nirbhay having capability to carry nuclear warheads, Russia stopped supply of engine. This came as a blessing in disguise as the DRDO was compelled to work on an indigenous engine with Russian help. According to sources, this project is moving satisfactorily and once India develops its own seeker there will be a commonality of seeker between three missiles - BrahMos, Nirbhay and even the Russian 3M14 Club with the Indian Navy.

To place in the global perspective, cruise missiles are the weapon of choice rather than the ballistic missiles because they are less expensive; are easier to design, develop, procure, maintain and operate; have wider applications in conventional warfare, including in unmanned aerial vehicles; and have fewer technology restriction, especially so since India is a member of the Missile Technology Control Regime since 2016. Given all this, the test-firing of BrahMos-A should not be delayed since it opens up avenues for India to acquire state-of-the-art technologies.

Firm to take a call based on incentives offered by the States

Larsen & Toubro Ltd., is eyeing Tamil Nadu, Maharashtra and Gujarat for its ₹500 crore missile and missile systems plant, said a senior executive.

“We are looking at Tamil Nadu, Maharashtra and even Gujarat,” said Jayant D. Patil, member of the board and whole time director (Defence Business). The location would be finalised based on the incentives offered by these state governments, he added.

The missile and missile systems plant is being formed in a joint venture with MBDA, a French company. The new joint venture company, L&T MBDA Missile Systems Ltd., will have an equity stake of 51:49.

Besides, L&T, in partnership with South Korean firm Hanwha, would be setting up a battle tank plant at Hazira in Gujarat. This will cost more than ₹500 crore. The project is going ahead as per schedule, Mr. Patil said.

Wind tunnel facility

On construction of a ₹250-crore wind tunnel facility for DRDO, he said: “Earlier, we had constructed a wind tunnel for ISRO and this is a repeat order. We have done half of it. The remaining portion will be completed in about 18 months.”

According to Mr. Patil, L&T has an order book of ₹2,300 crore to ₹2,400 crore, including an export order of $100 million from Vietnam, for delivery of high speed interceptor boats.

NIRBHAY


http://www.thehindu.com/news/nation...rbhay-set-for-fifth-trial/article19987030.ece

India’s indigenous subsonic cruise missile, Nirbhay, which failed its last test in December 2016, is ready for its fifth trial, DRDO chief S. Christopher said on Sunday.

“We are planning to have one probable trial (of the missile) next week,” Mr. Christopher said on the sidelines of a three-day international conference Fipsphysiocon-2017, organised by the Defence Institute of Physiology and Allied Sciences.

The DRDO chief said the glitches that led to failure in its fourth trial in December 2016 have been removed. Nirbhay’s December 2016 trial was aborted half-way as the missile changed its targeted course. It had to be destroyed within minutes of taking off amid a threat that the missile could hit land.

The 750-1,000 km-long range missile’s first test on March 12, 2013 failed as it fell after 20 minutes of flight. The second on October 17, 2014 was, however, successful. The third test on October 16, 2015 saw the missile nose-dive after covering 128 km in the Bay of Bengal.

The cruise missile is expected to supplement the Indo-Russian joint venture supersonic cruise missile BrahMos, which can carry warheads up to 290 km. The two-stage missile has a length of six metres, a diameter of 0.52 m, a wing span of 2.7 m, and a launch weight of about 1,500 kg.

With the capability to strike deep into enemy territory, Nirbhay has been designed and developed by the DRDO at it’s aeronautics R&D laboratory ADE (Aeronautical Development Establishment) based in Bengaluru.

The cruise missile is powered by a solid rocket motor booster developed by the Advanced Systems Laboratory (ASL) and is guided by a highly advanced inertial navigation system indigenously developed by Research Centre Imarat (RCI).

DRDO Conducts Successful Flight Trial of 'NIRBHAY' Sub-Sonic Cruise Missile

Defence Research and Development Organisation (DRDO) achieved yet another feat today with the successful test flight of ‘NIRBHAY’ - India’s first indigenously designed and developed Long Range Sub-Sonic Cruise Missile which can be deployed from multiple platforms. It was successfully test fired from the Integrated Test Range (ITR), Chandipur, Odisha. The missile has the capability to loiter and cruise at 0.7 Mach, at altitudes as low as 100 m. The flight test achieved all the mission objectives completely from lift-off till the final splash, boosting the confidence of all scientists associated with the trial.

The missile took-off in the programmed manner and all critical operations viz. launch phase, booster deployment, engine start, wing deployment and other operational parameters demonstrated through autonomous way point navigation. The guidance, control and navigation system of the missile is configured around the indigenously designed Ring Laser Gyroscope (RLG) and MEMS based Inertial Navigation System (INS) along with GPS system. The missile majestically cruised for a total time duration of 50 minutes, achieving the range of 647 km. The missile was tracked with the help of ground based radars and other parameters were monitored by indigenous telemetry stations developed by DRDO.

Raksha Mantri Smt Nirmala Sitharaman, hailed the success of DRDO Scientists and complimented them for this inspired achievement. She was optimistic that this successful trial would take India to the select League of Nations for possessing this complex technology and sub-sonic cruise missile capability.

Chairman DRDO and Secretary Department of Defence (R&D), Dr. S Christopher, DG (Aero) Dr. CP Ramanarayanan, Director ADE, RCI , ITR and CEMILAC, along with other senior DRDO scientists and user representatives from Army witnessed the momentous launch and congratulated the team ‘NIRBHAY’ for making DRDO proud for the long awaited achievement.
