    Sorry, don’t get too excited…………..Just a small bureaucratic snag from the last adminstration (Bush) and the new one. (Obama) Which, will be resolved in short order………;) Nothing new……:o

    OK Sir, this is not our first excitement!! Repeated excitement is really bad for health. 😉 US administrations did the same many times for almost all the projects that have used COTS products from US and international market.

    A MILESTONE: Interceptor missile being launched from the Wheeler Island on Friday. —

    CHENNAI: It was a hat-trick for the Defence Research and Development Organisation (DRDO).

    In a third successful mission, it proved on Friday that India could shield itself against ballistic missiles from enemy countries by successfully testing an interceptor missile from the Wheeler Island off the Orissa coast. The interceptor shot down a Dhanush missile heading towards the island.

    The interception took place at an altitude of 80 km over the Bay of Bengal. The Dhanush missile was destroyed in its path in both a direct-hit and detonation of the warhead of the interceptor, which is an advanced Prithvi missile.

    Dhanush was simulating the trajectory of ballistic missiles with a range of 1,500 km, similar to Pakistan’s Ghauri.

    The previous successful missions took place on November 27, 2006 and December 6, 2007, when incoming “enemy” ballistic missiles were destroyed in direct-hits at an altitude of 48 km and 15 km respectively.

    V.K. Saraswat, Programme Director, Air Defence, called the Friday success “a major milestone in the direction of proving the capability of our ballistic missile defence (BMD) shield.”

    He told The Hindu from the Wheeler Island: “The success proves the robustness, reliability and repeatability of the design of our system for engaging incoming ballistic missiles with a range of 300 km to 1,500 km.”

    As the plot-boards in the Launch Control Centre on the Wheeler Island showed that the “enemy” missile was pulverised in its track, DRDO’s young missile technologists turned jubilant. They carried Dr. Saraswat on their shoulders and took him around, shouting, “DRDO Jai Ho, DRDO zindabad, DRDO hip hip hooray.’

    Dr. Saraswat described it as “total mood of euphoria and excitement.”

    M. Natarajan, Scientific Advisor to the Defence Minister, watched the mission from the Wheeler Island.

    W. Selvamurthy, Chief Controller, DRDO, called it “a hat-trick and an important milestone for achieving the BMD shield for the country.”

    Manoeuvrable warhead

    The interceptor used for the first time a manoeuvrable warhead called gimballed directional warhead (GDW), which can rotate 360 degrees.

    As the single-stage Dhanush, 9.4 metres tall and weighing 4.5 tonnes, lifted off at 4.17 p.m. from the ship located 150 km away from the Wheeler Island, radars at Konark and Paradip in Orissa tracked it 50 seconds into its flight. The Mission Control Centre (the MCC) on the island also received information about it.

    The MCC declared it a hostile target and that it would impact very close to the island. This data was used by the Launch Control Centre (LCC) to compute the trajectory of the interceptor, called Prithvi Air Defence (PAD II), to engage the target missile at an altitude of 80 km. The LCC also automatically decided when the interceptor should lift off and the launch computer gave the command for it.

    About 160 seconds into the flight of Dhanush plus 150 seconds after the lift-off of the interceptor, the interceptor’s homing seeker acquired the target. Using this information, the interceptor’s computer guided it towards the target and brought it very close to it. At this point of time, the radio proximity fuse (RPF) of the GDW computed the time at which it should explode.

    Direct hit

    Dr. Saraswat, who is also Chief Controller, DRDO, said: “When the target and the interceptor were practically colliding with each other, the warhead was detonated which led to the fragmentation of the target and the interceptor. It was a direct hit and also warhead detonation. The large number of fragments formed due to collision and detonation were tracked by the ground radars and we could see that hundreds of new tracks had been formed, confirming that the target was destroyed in both a direct hit and detonation.”

    He praised the young scientists of the DRDO’s missile complex at Hyderabad and other DRDO laboratories for the mission’s success.

    “It was one of the most complex missions planned, designed and executed by the DRDO with clock-work precision. I feel satisfied that the BMD shield of the DRDO has reached a great level of maturity.”

    The interceptor was a two-stage vehicle, with the first stage fuelled by liquid propellants and the second stage by solid propellants. It was 10 metres long and weighed 5.2 tonnes.

    First phase development tests are over now they will go for three to four field trial before the system is operational. I think from now on-wards they will concentrate on AD-1 and AD-2. :diablo:

    Scientists had also indicated yesterday that DRDO would need to carry out at least three to four further trials with both the endo and exo-atmospheric versions of the missile shield before declaring it operational.”The test will mark the completion of the first phase of the programme and it will secure operational clearance by 2012-13,” a scientist said.

    The last time they tried to tell the Army it was a success when it failed. So this time they have every right to double and triple check the result.

    The Brahmos missile already fired by the Army many times and it is in service, what do you want to say about that?? Are those missiles failed???!!!! Yes they can check the result double, triple even quadruple times as they want but you should not come to a conclusion that the missile has failed. It is a new sophisticated development effort, so further trials will be there.

    BrahMos missile test-fired successfully

    A MILESTONE: The BrahMos missile being launched at Chandipur-on-sea on Sunday.

    CHANDIPUR-ON-SEA: Supersonic cruise missile BrahMos, with an advanced capability of sharp manoeuvring, was successfully test-fired on Sunday from the Integrated Test Range at Chandipur-on-sea in Orissa. For the first time it was manoeuvred in the form of an “S” curve at a supersonic speed of 2.8 mach. Army personnel in full combat formation carried out the firing.

    This is the 13th flight of the missile, which is jointly developed by India and Russia, and the fourth for the Army.

    The Russians do not need Indian guidance systems. They it seems don’t even need the missile. Their commitment to the Brahmos remains iffy at best. The whole Brahmos thing for me was a Russian exercise at exploiting the Indian need for JVs than outright purchases.

    Something new from you, I am hearing it for the first time!!! Can you give some source for your claims????

    If Russia do not need India, why Russia fail to induct the Yakhont??? Why now many takers for the Brahmos??

    It is better served us taking out small single targets like ships etc, than large targets a conventional cruise missile can take out. Its short range is another handicap making the Launch platforms vulnerable. . I would even take something like the Babur over Brahmos anyday. It has better range and payload, add that with some good terrain hugging guidance and its a winning combo.

    You are comparing Tomahawk with Brahmos!!! They are completely two different type of systems for different purposes. lol Do you know what is called a battle field missile like LORA/ATACMS/Iskander ?? Thats why I have given you example of Nirbhay. You first learn about these and than we will talk. :rolleyes:

    1. DRDO can claim what they want to. The Army is the enduser and knows their operational requirements more than the DRDO. So if the missile do not meet it, then the Army says its a failure i believe the Army over the DRDO who has vested interests.

    Does Army said that the Brahmos failed to meet their requirements???!!!! As far as news report are concerned, they are analyzing the data but seems like you have gone to a conclusion!

    Do you know what are the operational requirements of IA?? Does they want some mythical system??? I think you about the capabilities of Brahmos Block-II. Than no company/org in this world will be able to meet IA’s requirements. But IA is pretty happy with Russian systems like T-90S, which failed many times still inferior!!

    2. India did not ‘develop’ the Brahmos missile on its own, the Indian components are just the guidance systems, etc. We are sitll dependent on Russia for the missile. We don;t even get full ToT.

    From where ToT things comes for a JV!!!! Who said the Indian component is just guidance system?? We are dependent on Russia and Russia is also dependent on us for the missile that is a JV or joint development!! You do not know whether the Russians themselves asked for ToT of the guidance systems or not!!! lol

    3. For a land based Cruise Missile Payload and Range is more important. I would rather have a Tomahawk any day.

    Will you jointly develop a Tomahawk with Russia??!!! lol Do you know about Nirbhay?

    There are requirements of short range, high accuracy, high speed and intellegent missile for battle field. The Brahmos if properly used can change the course of war with in minutes as it is unstoppable with extreme lethality. As a precision weapon, capable of engaging time critical targets at high precision under all weather conditions. It can take out high value targets like missile launch pads, SAM/radar sites, oil depot with SEAD. The US has developed the ATACMS and the Israelis developed LORA for same purpose.

    USA!!! lol India will never learn! The P-8I and C-130J will cause India a lot forget MRCA. If India goes for any US fighter than it will be the greatest mistake of the Indian military history, second is Gorshkov. lol Americans did it for LCA, AWACS and many other programs. I think the same will happen for the IAC as well.

    BTW I liked the last part of the article…. 🙂

    US defence industry sources indicate that GE is upset by the State Department’s directives, which clearly damage GE’s commercial interests. The ban, suggest sources, was imposed by an “over-enthusiastic State Department bureaucrat”, keen to display that the Obama administration was on the ball from the beginning. But in India, the ban is already generating talk of an unwise choice in going for a US engine.

    For the first time they used a directional warhead for PAD, now we are sure that it is not a HTK like AAD. Also the target missile went to an altitude of 120 Km, so 75 Km kill is very satisfying. India should go first to deploy a two layered BMD with Pardyumna and Ashwin.

    I think India is the third country after USA and Russia to achieve a ballistic missile kill at that high altitude. 😀

    DRDO done it again…. IRBM/ICBM, SLBM, supersonic cruise missile, long range AESA/PESA/SWGA, AWACS, nuclear submarine, integrated EW systems, stealth ship, 4th generation fighter, heavy weight MBT, NBC, thermonuclear weapons and now this……

    From MoD

    India today inched closer towards its endeavour to put in place its own home-grown Ballistic Missile Defence System as it successfully carried out the third Interceptor test today at 1624 hrs from Integrated Test Range (ITR) at Wheeler Island in Orissa. The mission control room burst into raptures as the radar display indicated the interception and destruction of the decoy enemy missile by the interceptor. Today’s test achieved all the mission objectives. The two-stage Interceptor Missile fitted with advanced systems hit the target enemy missile at 75 kms altitude.

    To mimic the incoming enemy’s ballistic missile trajectory, Dhanush missile went to an altitude of 120 Km and was launched from ship about 100 km away from the Orissa Coast. The Interceptor missile was launched from a mobile launcher located on Wheeler Island Launch Complex.

    The third consecutive interception of Ballistic Missiles once again demonstrated the robustness of the Indian Ballistic Missile Defence (BMD) system. The Defence Research and Development Organization (DRDO) have already conducted two interception trials, first in Exo-atmospheric region at 48 Kms altitude on 27th November 06 and second in endo-atmospheric region at 15 kms using Advanced Air Defence (AAD) missile on 06 Dec 07.

    The missile interception trial was witnessed by the DRDO Chief Shri M Natarajan, Air Defence Programme Director Dr VK Saraswat, senior Scientists from DRDO, senior officers from Armed Forces and Government officials. The Defence Minister Shri A K Antony has congratulated the scientific community of DRDO for the third consecutive success in achieving Ballistic Missile Defence capability.

    Missile defence shield: India to test interceptor on Friday

    New Delhi (IANS): India will on Friday test launch its indigenous interceptor missile that will destroy an incoming ballistic “enemy” missile at an altitude of 80 km and will provide defence against Pakistani and Chinese missiles, an official said.

    “All the preparations have been made and all the scientists are working to make the test successful,” a Defence Research and Development Organisation (DRDO) official said.

    The test, to be conducted at Wheeler’s Island off the coast of Orissa, will establish the credible missile defence against Paksitan’s Hatf and Ghauri missiles. The first test of the interceptor missile was conducted in 2006.

    “During the test an ‘enemy’ missile which will be a modified version of the Dhanush surface-to-surface missile will will be fired from a naval ship in the Bay of Bengal and simulate the terminal phase of the flight of a ballistic missile with a range of 1,500 km, similar to Pakistan’s Ghauri missile,” he official said.

    “As the incoming missile nears Wheeler Island, a Prithvi air defence missile will be launched to intercept it at an altitude of about 80 km and kill it,” the official added.

    DRDO needs to carry out at least three to four trials with both versions before the missile shield is certified for operational use.

    “The test will mark the completion of the first phase of the programme and it will secure operational clearance by 2012-13,” he added.

    On December 6, 2007, DRDO had for the second time successfully tested an endo-atmospheric – below 30 km altitude – version of the ballistic missile defence shield. The missile aims to protect populated areas and vital installations like nuclear power stations and oil wells.

    The missile shield will have highly sensitive radars to track incoming missiles. The guidance system would ensure that the interceptor collides with the incoming missile within a matter of seconds, thereby saving vital targets from destruction.

    Baptised as the Prithvi Air Defence system, the agile interceptor has now been renamed Pradyumna.

    DRDO says its missile system is comparable to the Israeli Arrow system and the American Patriot system, both of whose manufacturers are courting the Indian defence establishment for possible orders.

    It expects ballistic missile shield to take care of threats from existing Chinese and Pakistani missiles. While Pakistan possesses missiles with ranges between 400 and 2,000 km, the Chinese arsenal varies from a range of 300 km to 2,800 km.

    I am not very optimistic about the land based Brahmos. My sentiments are almost the same with the likes of Johnsey with regards to that. DRDO is trying to sell its **** to the Army….

    As far as the news report are concerned, the test was successful. So you might wait for further report before posting BS…

    I think you need to know that Brahmos is already in service of the Indian Army and you must watch this video as well…… Show me any other high speed cruise missile with such accuracy…..

    The Block-I version was a great success. This is Block-II, they are doing something new and the first country to do so. Do you know how may failure US/Russia do have when developing something new???!!!
    How many countries has a missile similar to Brahmos Block -II???

    DRDO says BrahMos test a success, Army sceptical

    http://www.ptinews.com/pti%5Cptisite.nsf/0/4DAA8CF0E6502CA06525756F0052EF08?OpenDocument

    “We do not want to hurry up things and make a wrong claim on the test-firing of BrahMos. We are the end-users of the missile and we want to be 100 per cent sure of the weapon system’s effectiveness before making our views on today’s test known,” senior Army officers said.

    I think Directional warhead means, “provide expanded angular explosive coverage forward and aft in the horizontal plane upon detonation of the warhead.” So it is maximum utilization of the damage potential with forcing the warhead to detonate at a particular direction not 360 deg as mentioned in this article!!!!!

    Crucial interceptor missile test this week

    Y. Mallikarjun & T.S. Subramanian

    It will establish India’s capability to intercept Pakistan’s Hatf and Ghauri missiles

    PAD will also feature “trajectory optimisation”

    PAD missile will use gimballed directional warhead for the first time

    CHENNAI: A missile which will waylay and destroy an incoming ballistic “enemy” at an altitude of about 80 km will be launched off the coast of Orissa later this week.

    Network-centric warfare

    This “crucial test” will seek to prove the efficacy of a host of new technologies, said officials in the Defence Research and Development Organisation (DRDO), which is conducting it. They described it as “a major test to establish a ballistic missile defence [BMD] shield as part of the network-centric warfare.” This is the third time an interceptor missile test is being conducted under the BMD shield that India seeks to establish.

    The launch will feature two missiles. The “enemy” missile will be a modified version of Dhanush, a surface-to-surface missile. It will take off from a naval ship in the Bay of Bengal and simulate the terminal phase of the flight of a ballistic missile with a range of 1,500 km, similar to Pakistan’s Ghauri. As it zeroes in on the Wheeler Island, off Damra village on the Orissa coast, a Prithvi Air Defence (PAD) missile will lift off from the Wheeler Island, intercept the incoming “enemy” missile at an altitude of 70-80 km in the last one second and a half of its flight and pulverise it.

    The interceptor PAD missile will use,for the first time, the gimballed directional warhead. It has so far been used only in the U.S. and Russia. When the directional warhead fragments in 360 degrees all round, the target missile coming in from only one direction is sure to be blown up. “Ground tests have been done on the directional warhead. In flight, it will be done for the first time. This is a new thing,” the DRDO officials said.

    Light, lethal

    A directional warhead weighs less than 30 kg but its lethality is equivalent to a 150-kg warhead. The PAD would also feature “trajectory optimisation” to enable interception at not only a higher altitude of 80 or 85 km but also at 45 km. It could engage missiles with a range of 300 to 1,500 km.

    Risk elimination

    “The distinct advantage” of intercepting a missile at a higher altitude of 80 km is that the debris will take longer to fall through the atmosphere before it hits the ground and hence will become cinders because of the re-entry of heat, the DRDO officials said. In a typical war scenario, this would reduce the effect of any fallout of nuclear debris and the risk associated with radiation.

    The first interceptor missile test, which took place on November 27, 2006, waylaid an incoming ballistic missile in the exo-atmosphere at 48-km altitude. The second test took place on December 6, 2007 against a target missile at 15-km altitude in endo-atmosphere. The third test would be part of India’s plan to deploy a two-layered BMD system in the coming years.

    In terms of strategic importance, the test would establish India’s capability to intercept Pakistan’s Hatf and Ghauri missiles.

    After eight hours they could not find whether the missile hit a target 50 km away??!!!! If the IA’s ‘general staff quality requirements’ are like that than no other nation except Russia will be able to meet IA’s reqs! Because they generaly love Russian eqpmts!! Do not know why!!!!

    Brahmos test flight result in wraps
    OUR BUREAU

    New Delhi, March 4: Suspense shrouded the outcome of a test of an advanced version of India’s sole cruise missile, Brahmos, tonight with defence scientists and army officials unwilling to disclose whether the missile had struck its target.

    More than eight hours after the planned 150-second test flight of the Brahmos-Mark II cruise missile in Rajasthan’s Pokhran firing range, army sources said they were “still evaluating” whether the 290km-range missile had hit its intended target.

    The Brahmos supersonic cruise missile — a weapon designed to home onto targets with the help of sophisticated software — has been developed under a joint project between India’s Defence Research and Development Organisation and a Russian company.

    Several tests of the first generation of Brahmos have already been successfully conducted. The army has already raised a regiment of this first version: Brahmos Mark I.

    A test of an advanced Brahmos Mark II on January 20 had failed in mid-flight after a successful launch.

    A few hours after today’s test, DRDO sources declared it as “largely successful” while army sources said they were “evaluating whether the mission had met all the general staff quality requirements”.

    New BrahMos test successful

    T.S. Subramanian

    CHENNAI: A new version of the BrahMos supersonic cruise missile meant to attack a particular target out of a cluster on land was successfully tested at the Army’s range at Pokhran, Rajasthan, on Wednesday.

    This was its 19th flight and the launch took place at 10.35 a.m. In its previous flight on January 20 it missed the target following a software glitch.

    This variant is called the Block II version. BrahMos is essentially an anti-ship missile.

    Informed sources described it as “a difficult mission” because the target was just 50 km away instead of the normal range of 290 km. Besides, the missile had to perform “a discriminatory role”: it had to hit the desired target out of a cluster of small targets, resembling “a factory-type situation.” The time given to the missile to perform manoeuvres and hit the target was much less than the normal flight. But these “constraints were overcome” with the Global Positioning System (GPS) update coming in correctly and the missile homed in on the desired target, sources said.

    The missile flew at a velocity of Mach 2, twice the speed of sound. The normal version flies at Mach 3.

    Last time the missile failed to hit the target as the GPS did not have time to correct the error in the inertial navigation system (INS). So the GPS update did not come in. This time, the Defence Research and Development Organisation (DRDO) ensured that even if the GPS update did not flow in, the missile would hit the target. Modifications were made in the software and simulation runs conducted.

    The launch met different mission requirements.

    No way it’s going to happen to India. 🙂 No danger of hybris there. The SU not only had only money to burn (till it was burned thouroughly) but a military industrial complex and scores of skilled specialists that actually did produce something indigenous at fast rates and steadily asked for more funds for more new, daring and costly projects that finally pushed Humpty Dumpty down the wall :D. India has money to burn… and that’s it. You can’t burn so much during such a long time on cancelled/failed/20% indigenous cancelled/failed projects.

    But what I’ve always liked with India is the permanent and steady optimism coupled with overtly irrealistic planning. I think it was actually the DRDO and the like that actually invented the “Yes we can!” motto and keep re-inventing it since 15 years or so 😀

    Sorry for the rant but please do name a single Indian indigenous project that was a)not subject to cost overruns b) not a direct beneficiary to foreign previous R&D c) completed before it was outdated already/not needed by the military anymore.
    Then I’ll eat my hat, I promise 🙂

    Please not in this thread. If you want to discuss about DRDO’s success create a new thread for that. Above all your knowledge about DRDO seems to be very low.

    In order to counter Chinese Navy, we will need more subs and anti-sub warfare systems, thats where they are concentrating on. Then again China having a larger navy will automatically trigger an arms race, korea and Japan may build up as well, so its unlikely that her resources can be concentrated to one threat.

    Our sub and anti-sub warfare systems are pretty cool wrt PLAN. We are getting systems from Russia, Israel, Italy, France and US as well as indigenous systems for anti-sub warfare. For example China have no submarine as capable as Scorpene and IN going for second line submarine as well. New P-28 dedicated ASW corvettes. P-8I MPA is also a good system. Bears are also been upgraded with latest systems. Various new generation naval sensors and torpedoes are under development as well.

    Devils Advocate

    Looks like you’re following a parallel of the Soviet Union during the Cold War. What happened to them again?

    USSR was neither a democracy nor the second fastest economy. :dev2:
