India’s longest range nuclear-capable Agni-III was successfully test-fired from the Wheeler Island, off the Orissa coast on Sunday.



The more than 3,500-km range home-grown ballistic missile, believed to be most lethal of the weapon systems developed by the Defence Research and Development Organisation (DRDO) scientists, was test-fired at 10.50 hrs and covered the pre-designated range with 100 per cent accuracy, top officials told The Hindu from Wheeler Island soon after the successful launch.



The solid-propelled, two-stage missile can carry nuclear warheads weighing up to 1.5 tonnes. It is 17 metres tall and has a launch weight of 50 tonnes with a two-metre diameter.



When contacted, V.K. Saraswat, Scientific Advisor to Defence Minister and Director-General, DRDO, said it was a fantastic launch and a “hat-trick for Agni-III with three successes”. The trajectory went perfectly according to plan till the last decimal place, he said. “It gave us full range and pinpoint accuracy,” he added.



Avinash Chander, Agni-III mission director, called it a “perfect success”, stating that all the mission objectives were met. Chander, also the Director of Advanced Systems Laboratory - which designed and developed the Agni-III - said all the events listed in the launch were executed with accuracy and described it as a “thrilling experience".



A. Sivathanu Pillai, CEO and MD, BrahMos Aerospace, called the success an “important milestone for the country. It will lead to induction of the missile”. The success would bring credit to DRDO scientists, he said.



W. Selvamurthy, Chief Controller, Life Sciences and Human Resources, DRDO also termed it as an “important milestone in developing the country's defence and developing the second strike capability. The flight proved the robustbness of all the systems and software”.



With the third consecutive success of Agni-III, he said “it is now a proven missile. It is a big morale booster for our missile scientists and institutions”, he observed.



A top DRDO missile technologist said the mission was a “good success and the trajectory of the flight was excellent. Everything worked well, including all payload systems”, he added.



Even though the missile did not carry a live warhead, its nuclear triggering mechanism worked well. Instead of a nuclear warhead, it carried chemical explosives, the missile technologist added.

Quote:T. S. Subramanian, Y. Mallikarjun



The launch of Agni-III, the missile with the longest range in India’s arsenal, from the Wheeler Island off Orissa on Sunday was a complete success.



Lifting off majestically at 10.50 a.m., it travelled its entire range of 3,500 km. and came down accurately on its target in the Bay of Bengal. [color="#0000ff"]{Arun_S: Notice the target was in Bay Of Bengal, not Indian Ocean (unlike the first successful test of Agni-III. Bay of Bengal ends when it touches Sumatra Islands @ ~1,900 Km. To cross equator the range has to be 2000 Km. Clearly the stated 3,500 km would go far beyond Bay of Bengal}[/color]



During its 800-second flight, it reached an altitude of 350 km. and its re-entry module sliced into the atmosphere, withstanding searing temperatures of 3,000 deg. Celsius.



The two-stage, surface-to-surface ballistic missile can carry nuclear warheads.



The [color="#4169e1"]nuclear triggering mechanism worked well although the missile carried only chemical explosives as payload[/color].



An elated V.K. Saraswat, Scientific Adviser to the Defence Minister, called it “a fantastic launch and a hat-trick.”



Talking to The Hindu from Wheeler Island, he said, “it shows the maturity of the missile’s design and the quality of its systems because we have had three successes in a row without any blemish.”



“The flight gave us the full range and pin-point accuracy. [color="#4169e1"]The missile travelled accurately its entire range to its last decimal place as we had planned.[/color] ”



Jubilation in the control room



As the nuclear-capable Agni-III missile zeroed in on the pre-designated target in the Bay of Bengal with copybook precision, anxiety turned into an all-round jubilation in the control room at Wheeler Island off the Orissa coast on Sunday.



There were loud shouts, clapping, hand-shaking and hugging as missile scientists, software experts and other team members congratulated each other.



“It was all about the success of the efforts put in by DRDO scientists and the anticipation of the user agency of the excellent system being acquired by then,” said a top DRDO official in the control room.



Later, the euphoric staff carried V.K. Saraswat, Scientific Adviser to the Defence Minister; Avinash Chander, Agni Mission Director; and V.G. Sekaran, Project Director, on their shoulders.



Dr. Saraswat congratulated the scientists for scoring a hat-trick of successes with Agni-III.



He urged them to continue with their hard work and make a grand success of Agni-V, which is planned to be launched by the end of the year.

Quote: Josy Joseph / DNA Sunday, February 7, 2010 15:38 IST New Delhi: Agni-3, India’s most powerful nuclear capable missile, was successfully test-fired on Sunday. The 3,500 km-range indigenous ballistic missile is ready for induction into the armed forces.



The missile, that will work as a key nuclear deterrent against neighbours, especially China, was flight-tested from Wheeler island in the Bay of Bengal, off the Orissa coast. It can reach its target in about 15 minutes, and can strike deep inside China and Pakistan from safe bases deep inside the Indian mainland, the Defence Research and Development Organisation (DRDO) said.

“The missile, tested for the full range, hit the target with pin-point accuracy and met all mission objectives,’’ the DRDO said. “The missile system will be inducted into the armed forces,’’ defence ministry spokesman Sitanshu Kar said.



The marker pen-like Agni-3 missile is 17 metres in length and two metres in diameter. It has a two-stage solid propellant system and can carry 1.5 tonnes of payload. During the course of flight, the missile reached a peak height of 350 km and re-entered the atmosphere successfully “tolerating the skin temperatures of nearly 3,000 degree celsius’’, the statement said.



The military research agency said the missile has a new state-of-the-art computer system, and an advanced navigation system.

Today’s test was the fourth successful test of the missile. DRDO is presently working on a new version of Agni, with a range of over 5,000 km.

Quote: 7 Feb 2010, 1729 hrs IST,

Economic Times



NEW DELHI/BHADRAK: India on Sunday successfully test-fired its indigenous nuclear-capable Agni-III missile with a range of over 3,000-km and

which can hit targets deep in China, paving the way for its induction in the armed forces.



The successful test-firing of the Agni-III consolidates India's position among a select group of nations that have intermediate-range ballistic missile (IRBM) capability.



The Sunday test was its fourth and last pre-induction trial. "Now the missile system will be inducted in the armed forces," an official said in the national capital.



The missile, which is capable of carrying warheads weighing up to 1.5 tonnes, was tested from the Inner Wheeler Island at Dhamra, a launch site in Bhadrak district, about 200 km from Orissa capital Bhubaneswar, at 10.50 a.m. Two ships located near the target tracked and witnessed the missile reaching the target accurately.



This is the fourth test of the country's most powerful missile which has the capability to hit deep inside China, bringing cities like Shanghai and Beijing within its potent reach.



The missile has a two-stage solid propellant system. During the course of flight, the missile reached a peak height of 350 km and re-entered the atmosphere successfully, tolerating surface temperatures that reached nearly 3,000 degree Celsius.



"The test was highly successful. It met all the mission objectives. All the events took place as expected," S.P. Dash, director of the Integrated Test Range (ITR), told IANS from the site after the test.



"The launch is part of the pre-induction trials. The Indian Army (the user) has carried out the total launch operations guided by the DRDO (Defence Research and Development Organisation) scientists," an official said.



The first test, from the same defence base on July 9, 2006, was unsuccessful. The second stage of the rocket had failed to separate from the missile quickly enough and the missile had fallen short of its target.



The DRDO-developed missile was tested again on April 12, 2007 and May 9, 2008, and both the tests were successful.



Agni-III, one of the Agni series missiles, has a length of 17 metres, a diameter of 2 metres and a launch weight of 50 tonnes.



While Agni-I is a 750-800 km short-range missile, Agni-II has a range of more than 1,500 km. Both have already been inducted into the armed forces.



Defence Minister A.K. Antony termed the test of Agni-III as a remarkable achievement and congratulated DRDO chief V.K. Saraswat and other scientists for making it a success.



More than a hundred defence scientists witnessed the Sunday test. They included Saraswat and Avinash Chandra, director of the Agni-III programme.

During today's launch, the missile was fired from a mobile rail launcher, sources in Balasore said.



Defence Minister AK Antony congratulated DRDO chief VK Saraswat and the scientists involved in the Agni-III project on the "remarkable success" of the missile test.

Arunji,



1. Lets say 3500km covered in 800sec with 350km altitude max. This looks like a depressed trajectory, is'nt it ?

what would be its range if the same (unknown) payload is put on a max. range trajectory ? Unfortunately, I do not have access to ROCKSIM...



2. Has A-III been ever tested on a max -Q trajectory ?



3. So, it is ready for induction. Which means that unlike in the A-II case, people should hopefully not make the mistake of avoiding production trials when production shifts to BDL.



4. As of now, A-III has a better record than A-II. 3/4 vs 3/5. Even the failed trial was a partial success. Of course, development trials only validate the design. Hopefully, after A-II lessons are learnt and appropriate quality control is instituted, A-III production trials will be smooth.



5. A-V is likely to have the same first two stages an extra 3rd stage and probably the same guidance hardware, right ? Given this, would A-V trials help in further proving A-III reliability ?

Struss interstage; Is easy, reliable and small mass overhead. So second stage can be lighted and will separate itself from booster, while booster is coughing it last breath. No need for retro (decelerating motor) on booster.

There are quite a few variables to know for sure. Where did you lean the 800 second flight information?



Quote:2. Has A-III been ever tested on a max -Q trajectory ?

There many corners of flight envelop that require Max-Q proof flight. I am sure couple of teh sifficult Max-Q coreners has been tested in teh last 3 flights.

Yes.

Not just likey it will use teh same first 2 stages. Yes it will add to A3 readability.

The three A-IIIs after the first are different from the initial vehicle. They have a thermal insulation blanket around the F/S nozzle to prevent re-entrant exhaust heating. So we should rule out the first flight. Can some one plot on probability paper the three flights?

Arun_S, 800 sec is total time of flight. With the mass parameters(two stage, 50 tonne, 1.5 tonne payload) can you see what is the trajectory for 350km apogee? What is its terminal velocity? I don't like the low beta.

Cool.



Range can be easily determined once dimentions of its stages and total weight is reported.



Here is the Payload vs range graph of Agni-3 SL (It is gratifying to note that I first coned the name Agni-III SL (Sub-surface/Submarine Launched) has become the de-facto name of the sub launched Agni.

since its an MIRV and most likely with use an unreliable TN which is of ?KT,I am considering that it will have 5-8 MIRV`s onboard.And I will take the upper range for the same number of MIRV`s.

Can you conclude the specs that goes into ATV?

Sandeep Unnithan's article on the ATV said 3 MIRVs per K-XX.

There are 12 K-15s in the 4x3 rotary launchers, giving 12 warheads, and there will be 3 MIRVs per K-XX (A3SL) keeping the number of warheads the same.

Gagan, the use of probability paper plots is a quick way of determining the reliability at various confidence levels using rank median tables.



http://www.weibull.com/GPaper/ranks2_6.htm



In layman terms if you run three tests and they are all successful then you have 0.96549 reliability wiht 90 % confidence. So as you increase the test sample size you gain more reliability.



The goal should be to have higher than that for detergent. If you add the first test it reduces the reliability figure.

Given TN fizzle at POK-II and Man Mohan Singh's Civil Nuclear Agreement w/IAEA, USA and NSG, Indian missiles will not have credible TN weapon payload. The MIRV configuration will thus have to largely rely on smaller FBF weapons of 50 to 150 kt yield, sprinkled with presumably debugged TN warhead (that fizzled in POK-II). The missile range and the inventory of weapon grade Pu required will thus constrain Indian nuclear deterrence.



Arihant ATV with Agni MIRV will have to live with a mixed weapons payload configuration, resulting in short legs and small boom.

Hi Gagan ! Glad to have you here.



I guess my Agni missile page analysis and projection was very bothering to DRDO, and they decided to stump with the announcement that there will not be any Agni-4 missile (I have to locate the new paper link if you need reference), instead the next missile will be Agni-V. Based on the stated range of AGni-V as 5,500 Km, it is what I postulated as AGni-4. As far as I am concerned, the Agni of Sun, irrespective it is called Surya or Sun.



Will nor be surprised if the name Agni-4 will rise again as Pheonix in the form of another variant for Arihant.

Path up from Agni-3 is via addition of another 2 meter dia motor of ~ 8 tonne mass or a Small Upper Motor (SUM) that is inside the nose cone. (See figure "L" in my article "[url="http://www.indiaresearch.org/WayToACredibleDeterrent.pdf"]WayToACredibleDeterrent[/url]" ). Following

is based on SUM based configuration.
