so, ramana which stage actually participates in partial burn on orbit-course to target [third? I am assuming the 2nd stage burn time == flight time, and only the third stage need not burn constantly [again I am ingoring the possibility of slow burn].

ramana · Post by **ramana** » 21 Apr 2012 00:06

^^^
Both Rajat Pandit in TOI and TSR & YM wrote that the conical third stage ignited at re-entry. The only difference is the velocity they quote. 7km/sec vs 6 km/sec respectively. In fairness TSR and YM give the altitude at re-entry as 100km. Generally its 50km higher. So it could have slowed to 6km/sec at 100km altitude which makes sense.

I think the FS and SS sent it in an elliptic path and after going over the top at 600km, the TS was ignited to enable BGRV mode during re-entry. The fact that the TS has carbon not graphite case would enable heat resistance. Recall Shourya had to roll to cool it as it flew? Well if the case has carbon shield(V Sekhran's remarks) then it doesn't have to do that for the short burn time. I think TS burn time was around 30-40 secs. Then the 4th stage or HAM in the RV took over.

Recall earlier reports of 4th stage in the RV for A5?

Most of the time is in the ballistic path after SS separation to reach the 600km apogee and on to re-entry altitude 150km -100km.

Unlike TSP, we don't have the luxury of getting pre-tested missiles. So how come A5 is announced as ready for induction with this one test? What did I miss in terms of prior tests of A4 or prime etc. that makes this A5 test a clincher? Apologies if this has been discussed already.

Ramana,the same thought occured to me some time ago-about the A-series,that the smooth manner in which tests in recent times have been taking place indicate that the testing of an A-4 or A-5 might actually come from a "batch" that have been modularly manufactured.For the sake of argument,if a particular stage had a problem in assembly/pre-flight testing,it could be swiftly replaced by another from the batch.Having now achieved a min of 5K+ range,it should be simple matter to double the range by adding an extra /larger module for a particular stage.It also appears to have been dimensioned keeping in mind a sub-launched version.

SaiK · Post by **SaiK** » 21 Apr 2012 00:22

Okay, so potentially we could configure it in such a way that SS could also participate (composite) in bg mode., and in a5 case, it was not done that way.

And, once SS is released, the TS is silent till it reacheas about 150km height (g help), and then kicks in for the path correction or extention?

so, then only TS burn time may not match flight time. I am trying to understand the actual path.

Suraj · Post by **Suraj** » 21 Apr 2012 00:56

I am struck by the difference between how the recent A-IV test was conducted essentially without warning, and how the A-V test was done - the latter was almost a 3-day marriage baraat, the only thing missing being a bunch of drummers and Nadaswaram pipers behind the rail launcher as the locomotive carted it out of the covering shed. The A-V was probably semi-assembled around the time of the A-IV test. Critical A-V technologies like stage separation and the navigation systems were proofed by A-IV .

Unlike the older missiles whose first tests were very much independent prototype platforms without sufficient productization, the A-III, A-IV and A-V should be viewed separately. The A-III proofed the basic design of 2.0m wide solid motors, thrust controls and no fins at all, and more limited 3rd stage components. A-IV is basically a production-quality redesign of A-II, with solid motors, no vented interstages, no fins, and the payload section closer to what was on A-V . The A-V now combined the A-III's standardized 2.0m ICBM/SLBM motor, A-IV's stage separation technology and tested navigation system, and enhances the payload with a much more survivable RV.

Looking forward, I see them shortening and lightening the A-V using a greater composites in the first stage, with the third stage being either the current conical unitary warhead or a MIRV one. A-IV may be shortened further to enhance road mobility, and a truncated version of it constituting an A-I+ for SRBM coverage, unless they prefer the Shourya alone for that segment.

On the political front, there was clearly top down support for such an overt demonstration of capability, and guidance to ensure that officially stated range parameters were 5000kms only . It took a huge amount of guts to do it so openly for a first test, particularly after the Norks made a complete mess of launching their Chinese rocket. I think we underestimate the risk of the ridicule we would have encountered had there been an issue with this launch - as much as the success has spurred our perceived standing, the failure would have set it back quite a bit more, not just externally, but due to much greater caution from our political firmament. Doing this openly was a very bold political act, and I'd like to thank the decisionmakers for it, and congratulate them on a very successful gambit. The only thing that could outdo this would be a publicly announced underwater cold launch from the INS Arihant someday.

A Russian Opinion, sees Agni-V as a much needed stabilizer in Indo-China context.
May India develop many more such "artificial" stabilizers for CCP and PLA elite in Space, Mil-tech and neighbourhood Geopolitics before other standard stabilizers (like people to people exchanges , healthy balance of trade etc achieve critical mass).

The Friendly Indian Intercontinental Missile
RIA Novosti political commentator Dmitry Kosyrev
.
.
.

On May 11, 1998, India held underground nuclear tests in an attempt to outdo Pakistan, which had also planned (and successfully conducted) such tests a few days later. And with that two more nuclear powers were born. Like many other countries, Russia condemned the new nuclear powers for ignoring the universally accepted ban on expanding the nuclear club. Back then, many commentators observing Russia’s harsh reaction to these developments rightly noted that no one feared France’s nuclear arsenal, because France is a country that gave the world Dumas, Moliere, cheese and wine. It simply has no reason to use its nuclear weapons against Russia or any other country for that matter. The same reasoning was applied to India: Our friend has become stronger, so it is good news not bad.

This is also why Moscow, Beijing and Tokyo react differently to missile tests in North Korea. The first two countries don’t want any trouble just because the Japanese and Americans are afraid of the North Koreans. However, Pyongyang is very unlikely to fire a missile at China or Russia.

In other words, the intentions and interests of superpowers are more important in strategic planning than their capabilities. What are the intentions of Russia’s friend India, which has increased the striking range of its nuclear arms delivery vehicles?

The source of the threat

The most obvious answer is that this is bad news primarily for China, which is, by the way, Russia’ friend, too. Indeed, there’s no reason for India to aim its nuclear weapons against Africa or the United States, all the more so since Agni can’t reach U.S. shores anyway. However, all of China’s territory is now within reach.

For several years now, various political forces in India have been saying officially (and especially in private) that Indians aren’t dumb enough to turn their country into a missile base against China just because, for example, the United States wants it to be this way. Both major Indian parties agree on that.

Pakistan, whose government either unwilling or unable to control the jihadist groups residing on its territory, remains India’s primary threat. Pakistan’s nuclear arsenal is not the only concern here. The philosophy underlying the establishment of Pakistan as a Muslim alternative to Hindu India is another major consideration. It’s not clear what this nation will become without this idea, and whether Pakistan will remain a nation without it.

This is not all there is to it. Jihadism is not only about Pakistan. Let’s not forget that in addition to nuclear tests in 1998, India stepped up its political involvement in the Middle East and became very close with Israel. Today, with the Gulf monarchies successfully promoting the jihad philosophy across all Arab nations, such as Tunisia, Egypt and Libya to name a few, it has become clear that India’s policy was quite reasonable and the expansion of its missile range won’t hurt, either.

Next comes Iran. The Indian opposition strongly criticizes its current government for its incoherent policy towards Iran. However, the real threat to India doesn’t come from Iran. Hypothetically, if the United States or the Gulf monarchies manage to sow the seeds of chaos in Iran as well, then, in the worst-case scenario, extremist regimes will spring up from neighboring Pakistan westward all the way to the shores of the Atlantic.

This is something that China would like to avoid as well, because it has more shared strategic interests with India than with its old friend Pakistan.

Who’s your friend?

It is assumed that India’s failed war against China in 1962 and the loss of an uninhabited glacier in the Himalayas is a major problem that makes these two key international partners of Russia bitter enemies. If this were the case, then the launch of the Agni would spell real drama for Russian foreign policy.

Let’s keep in mind that Russia is India’s key partner in the area of armaments. This month Russia supplied to India the nuclear submarine Nerpa aka Chakra for a long-term lease. By late 2012, India will at long last receive the aircraft carrier Admiral Gorshkov aka Vikramaditya. There’s a whole list of armaments that Russia is either selling to India or designing together with India. If Beijing viewed India similar to the way Japan looks upon North Korea… And if India saw China – which, by the way, became Delhi’s first trading partner – as a source of permanent threat…

Things are different in reality, though. The foreign ministers of Russia, India and China (RIC) met this month. As it turns out, the original triangle of this group exists as a separate entity despite its expansion to include Brazil and South Africa (BRICS). And the three have more and more reasons for private meetings. Among other things, an important topic for discussion is coordinating efforts in Afghanistan once the U.S. and NATO forces withdraw. The problem is that the spread of jihad policies in Afghanistan represents a direct threat to northwestern China. As a result, Beijing and Delhi now have more reasons for rapprochement and Moscow has long been a willing intermediary.

As for nuclear arsenals and their delivery vehicles, even with an enhanced strike range, they do not interfere with such efforts. On the contrary, they are a source of calm for the partners in their complicated relations with each other.

Chinese expert Du Wenlong on India changing the Agni 5 missile range

People, April 18, according to the CCTV network reported, India’s most sophisticated, most powerful ballistic missile Agni-5 first test countdown. In this regard, the researcher at the Academy of Military Sciences Du Wenlong commented, compared to the four Agni series missile Agni -5 with India before the launch, with a longer range, faster response, more powerful features of the 5000 km range is not the actual range. operational theory of
Academy of Military Science and Doctrine Research Department is the division level researcher Duwen Long said, compared with before the Agni series of missiles, Agni -5 main three features:

long range. Range of 5000 km Indian Agni series of missiles in the range of up to an unprecedented height.

, quick reaction. The Agni series of missiles to take solid launch, Agni -1 to fire -4 are fat nude bomb, fire -5 According to Indian media reports in a closed container, in a relatively stable conditions, the detection time is very short. in the shortest time possible missile launch out. Its speed of response is the fastest in the Agni series.

powerful. Agni -5 can carry multiple sub-guided nuclear warheads able to attack different targets during the attack, you can also use two to three warheads to attack the same target, so the combat power of its goals is very large.

In addition, Du Wenlong also introduced the Indian authorities on the missile range and the title made a change, a range of 8000 km down to 5000 km, from the Intercontinental title back to the medium-range. Du Wenlong think, now released 5000 km range of a political, not an actual range of the reason for its range has so much shrinking, as long as it is for the following two considerations:

first, Agni -5 missile technology lack confidence, lack of confidence. If the announced range of 8000 km, if the actual range of less than the launch failed. If the beginning of 5000 kilometers, the actual launch beyond 5000 km, even if less than 8000 km launch was successful.

8000 km easily lead to the outside world, especially the U.S. response, such as some time ago the United States accused India of military force opaque. If the range is 5000 km, and 70% in Europe, most parts of Asia are covering. European region are the U.S. allies in NATO, it has also been included in within the range. If extended to 8000 km, the new Darwin in Australia, as the United States in the Asia-Pacific region’s growing power point in the future are India’s missile has a range of covers. Plus Cork Island, Diego Garcia, two points in the direction of the Indian Ocean are within range, including Russia, can also be overwritten. Announced a range of 8000 km, then I am afraid there will be voices raised in opposition, but also to make the launch in India with the challenges the United States means that (Ren Yan)

The Chinese media reports- I feel almost silly pointing it out- are all contrived. The idea is to denigrate India. One day, the Chinese media will say that India is overestimating itself, and that the missile isn't as far-ranging as claimed. The next day, the same media will state that the real range is considerably higher, thereby a possible threat to Europe.

The motive is to make India look bad, not to express some abstraction called 'the truth'.

On par with China, India doesn't inform neighbor about launch

India did not formally inform China about the launch of its intermediate-range ballistic missile Agni-5 from the Odisha coast yesterday, although it did notify all the other big powers about the event. According to government officials, who spoke on condition of anonymity, China was the only permanent member of the UN Security Council that Delhi did not speak to about the launch.

In fact, in the wake of the highly successful test that makes India the only developing country on a par with other missile powers like the US, China, Russia and France, and brings most of China under its radar, the ministry of external affairs continues to deliberately down-play the event. The Agni-V launch finds no mention at all on its website.

The officials pointed out that a general notice to marine traffic (NOTAM) had been issued and certainly with the Indian media widely talking about it, “there was nothing secret about the launch of the Agni-5.”

Delhi’s refusal to beat its chest is part of its recent pragmatic approach to foreign and security affairs, borrowed from the Deng Xiaoping school of thought, that it should keep its head down while pursuing a goal of making India a country to be reckoned with, which includes the maintenance of high economic growth.

According to Srikanth Kondapalli, professor of Chinese studies at the Jawaharlal Nehru University in Delhi, “Even if you have hundreds of Agni-5 missiles, the fact is that a nuclear weapon is a political weapon, it is a deterrent, it is never going to be used. However, the successful launch of the missile demonstrates to the Chinese that if you cross the red lines, India will have to think twice.”

That is why, government officials said, Delhi would continue to engage with the Chinese government as if it were business as usual. “The Chinese respect strength. We are not here to poke each other in the eye, but to continue to engage as equals,” one official said.

This Agni-V missile will be inducted in double quick time. Even with this upcoming single test, induction might be Oked. China factor is the reason. There are preparations in every front for such showdown.

As we gather from the available information revealed by officials, Agni V is more or less battle ready even before the launch of first test. They already knew that this launch will be a successful one before even launched. Key technologies are validated in previous several Agni missile tests. Agni IV is more closer to Agni V than Agni 2.

Many of the key technologies of Agni 5 was already tested in Agni 4 and probably in other Agni 2 missile tests.

Navigation & guidance, that is the brain of Agni 5 was already tested in Agni 4 (official news) and probably in other missiles and matured.

Re entry vehicle of Agni 5 is very similar to Agni 4. Parameters of the latest Flight test of Agni 4 is a precursor and pre-validation of Agni 5 flight characteristics.

Ramana sir, three phase or three stage guidance is Boost phase, mid course/coasting, and terminal phase guidance, common to any all guidance missile. Ex., all SAMs do have such three stage guidance.

Earlier Ballistic missile, do have only boost phase guidance. In contrary, this is an all guidance missile, meaning it is guided all the way from start to finish. Tessy Thomas mentioned the same .

Agni V can launch mini-satellites too

Posting in full:

Second variant of missile could be used to destroy enemy satellites in the low earth orbit

India can use its 5,000-km range Agni V missile to inject satellites in a low earth orbit at an altitude of 600-800 km to restore communication links, in the event of the country being denied access to its satellite constellations by the enemy.

A third version could be tailored to carry a multiple independently targetable reentry vehicle (MIRV) in which a single rocket can be used to launch many war heads on multiple enemy targets, rendering the missile defence system useless.

“Agni V can be used to launch mini-satellites in low earth orbits in a theatre battlefield when your major satellite constellation is denied,” said V K Saraswat, scientific adviser to the defence minister and Director-General of Defence Research and Development Organisation (DRDO).

However, these satellites will have short life span—between six months and one year—and have a specific purpose like restoring the communication links in an emergency situation.

A day after the successful maiden launch of Agni V, Saraswat said the three-stage rocket could be modified to make it an anti-satellite weapon though India strongly opposed any move towards weaponisation of space.

“Agni V gives us boosting capability (using booster rockets) to reach an altitude of 800 km and guidance for homing in on the satellite. We can use kinetic energy to destroy the payload or use shrapnel targeting the satellite. The tracking network is also in place,” he said.

The DRDO chief, however, refused to disclose Agni V’s actual range. “It is more than 5,000 km. I cannot give you the exact range. That's classified,” he said. Asked whether Agni V could be described as an inter-continental ballistic missile, Saraswat said he would prefer to describe it as a long-range ballistic missile.

The nuclear tipped missile, however, fits the criterion of an ICBM as it can reach other continents—Europe or Africa—when launched from India.

The Cabinet sanction for Agni V was accorded in December 2008. The government set a time frame of four years for the missile. The first flight happened within that time frame.

The Defence Research and Development Organisation keeps Agni V project cost under
wraps, though each of these missiles cost between Rs 60 crore and Rs 80 crore. Asked about the project cost sanctioned by the government, Agni programme director and chief controller (missile systems) Avinash Chander told Deccan Herald that the Cabinet approval on cost was a classified information.

Single warhead

Chander clarified that Agni V in its current configuration is a “single warhead” system as MIRV was still under development. The MIRV would draw heavily on Agni V.

Saraswat said India had no plan to cap the Agni programme. “There will be more Agni (presumably with increasing range) after Agni V. We don’t worry about other countries having missiles with longer range,” he said adding that two more tests of Agni V were required for validation before Agni V went to the production phase.

Four years from sanction/approval to first test is awesome.

Dec 2008 means aftermath of 26/11 Mumbai attack.

Also puts paid to Manu Pubby's ravings about delays!

Kanson, the fire control and guidance till now was for two stages. A5 is first with a third stage. All Agonys had guidance in RVs except for the first one in 1989.

BTW MIRV will have even more complex fire control and guidance.

So there it is. Officially it is acknowledged that Agni V has a range greater than 5000 km.

Ramana sir, we do have HAM (High Altitude Motor) in previous Agni missiles as per open sources, which is very similar(if we talk of guidance) to the third stage of Agni 5. We are not knew to such systems from guidance perspective and this is not the first.

And I checked, Tessy mentioned three stage guidance and there is no typo. Anything else is only our interpretation.

Agni hit within metres of target

The over 5,000 km-range Agni-V missile tested on Thursday had hit within a few metres of the target in the southern Indian Ocean and the test was declared a success since the missile hit well-within the circular error of probability (CEP) around the target, top DRDO sources said.
“The missile hit within (double-digit) metres of the target and it was well-within the CEP,” sources said. If a missile hits either the target directly or falls within the CEP around the target, a missile-test is declared a success.
Sources also said that the test was postponed — in the wake of heavy lightning off the Orissa coast — by a day on Wednesday since “lightning was unsafe for the propellant (of the missile). “Also, with heavy clouds, you can’t get optical tracking data,” DRDO sources said.
DRDO sources also said the success of the Agni-V long-range ballistic missile test can be considered as having Inter-continental Ballistic Missile (ICBM) capability since the missile has the range to cross continents.
Meanwhile, DRDO chief Dr V.K. Saraswat said the DRDO had performed very well as an organisation in the past 10 years.

The last thing to find out is if like A4 sat nav signal were ignored. That would be a real achievement for over a shot of 5,000 km.
