Surya..

every missile test of strategic importance has its own connotations..

If they can wait for years to test the Agni-III.. why they pack this test before and after the Hu's visit.

Last time, they fired a Agni missile like this after the premier left.

There are still a lot of tests to go. What will be more significant is if the missile can engage, BM's that zig zag. Should I take a video of the clip on NDTV and upload?

Shyamd, there is a lot of technical info in the press reports that indicate an advanced 'kill' vehicle was developed and tested. The video might hep if played frame by frame.

No you shall not. Copyright infringement will get you into trouble.

FYI .. our footage shows the liftoff but not the actual interception. It also shows contrails in the air following the impact.

Did NDTV or any other media entity get a specific invite to use their own recording equipment to capture exclusive footage? OR did NDTV or any other mediawalla PAY for said footage if they were not invited to film the launch?

I believe all the footage/pics of all missile testing comes from DRDO itself (see the A-III footage issue) and since its a GOI entity there should be no copyright issue. Unless there are other issues that we are not aware off.

While the target misile was shown all the way from launch to destruction the location of the interceptor missile could only be guessed from the post intercept contrails.It is obvious the actual intercept was edited out .That brings two questions ot the fore .If it is a new missile showing it carrying out the actual intercept would have many times more impressive .The reason why it was edited out of the press release video was obviously because it would have compromised the identity of the intercept missile.

Now if you look at the contrails of two impacting missiles the flight or rather the intercept profile of the defending missile is quite clear very very similar to arrow 2 intercept profile the angle of intercept particularly but instead of reentry cruise phase intercept this was surely terminal boost phase intercept just as the target missile started tipping over for the cruise when it has largets radar cross section and max altitude and minimum ground speed at that altitude .

Now speculating on the type of kill vehicle the target missile spiralled into three distinct smoke balls all along its estimated vertical position so it was most likely not a high explossive warhead exploding on direct impact but triggered by a superfast proximity fuse most likely laser type which explossively release a directional explossive charge ,kinetic energy particles on the projected path of the target prthvi missile at an altitude of 50 km when it starts tipping over to initiate cruise again a classic arrow 2 type intercept

India conducts missile vs missile test

Press Trust of India
Posted online: Monday, November 27, 2006 at 1256 hours IST
Updated: Monday, November 27, 2006 at 1302 hours IST

Missile Balasore, November 27: For the first time, India's defence scientists experimented with the coordinated launch of two surface-to-surface Prithvi-2 missiles from two different test ranges on the Orissa coast.

The Prithvi-2, as a target missile, was first launched from the launch complex no. 3 of the integrated test range (ITR) at Chandipur at around 1015 hours, defence sources said.

A second missile was fired from launch complex no. 4 located in the Wheeler's Island off the Bhadrak district coast in the Bay of Bengal about 60 seconds later to intercept the first, they said.

The scientists, who had launched the short range ballistic missile on a solo test flight on Sunday last from the Integrated Test Range (ITR) at Chandipur, 15 km from Balasore, conducted today's unique trial as part of the country's air defence exercise.

The project is termed as Prithvi Air Defence Exercise (PADE) and more such exercises may be undertaken to make it fullproof for the country's defence preparedness.

The trajectory of both missiles were programmed to intercept each other in mid-air over the sea.

Whether the experiment was successful or not was not immediately known.

The Wheeler's Island is located about 72 km south of Chandipur.

According to the sources, the target missile interception time was programme at 170/175 seconds while the missile from Wheeler's Island blasted off roughly 60 seconds later with interception time of 110/117 seconds.

The entire trajectory of both the missiles was tracked by the Defence Research and Development Organisation (DRDO) scientists using different telemetry stations, sophisticated radars and electro-optic telescopes.

The missiles carried dummy warheads, the sources said.

Prithvi-2 is a short range liquid propellant ballistic missile with a maximum range of 250 km with a 500 kg payload.

Both nuclear and conventional warheads can be fitted with the sophisticated missile and can be launched from a transporter-erector-launcher (TEL) vehicle designed to transport the missile along roads and railways.

The Chief Controller, Research and Development, DRDO, and programme Director V Saraswat and Director, Defence Research and Development Laboratory (DRDL), Hyderabad, Prahallad were present during the launching of the missiles.

Meanwhile, as a safety measure the Balasore district administration had temporarily evacuated about 600 families (2786 persons) living in a two km radius of the launch complex No. 3 at ITR, Chandipur, before the launch.

They were accomodated in two shelters set up for them.

Fishermen and trawlers operating along the coastal belt of Balasore and Bhadrak districts had also been asked not to venture into the sea between 8 am and 4 pm.

India successfully conducts missile vs missile exercise
Tuesday November 28 2006 00:00 IST

BALASORE: Marking a major milestone in the history of air defence programme in the country, defence scientists successfully conducted a missile vs missile exercise at the Interim Test Range (ITR) at Chandipur-on-sea on Monday.

This is for the first time that India conducted such a test and was successful. The success, however, comes four months after the failed test firing of the Intermediate Range Ballistic Missile (IRBM) Agni-III that was conducted on July 9 this year.

According to the sources, two nuclear-capable Prithvi-II missiles were test fired against each other from two different missile test ranges located in Orissa.

While one was fired from a mobile launcher LC-3 at the ITR in Chandipur-on-sea at 10.15 am, the second one went off in a minute later from another mobile launcher LC-4 in the Inner Wheeler Island in Bhadrak district about 70 km away.

While the missile from the LC-3 was assumed as the attacker, the LC-4 missile acted as defender.

"The missiles collided in the sky over the Bay of Bengal about 70 km from the ITR. The impact created a 'boom like sound' with the remnants of the missiles falling into the Bay. More such exercises may be undertaken to make it foolproof for the country's defence preparedness," a defence official said.

The aim and objective of the exercise is to test Prithvi-II's ability to provide an air-shield (cover) to important Indian metros and installations against hostile attacks. The missiles can also be moved closer to the Indio-Pak and Sino-Indian borders during crisis or wartime.

Director of ITR, A K Checker said, "All mission objectives have been met. We are, however, analysing the data and the detailed evaluation can be known after that."

The exercise was earlier scheduled for Sunday but was postponed in the last minute after scientists wanted to do some additional technical checks. Prithvi is one of the five missiles being developed under the Integrated Guided Missile Development Programme of the Defence Research and Development Organisation (DRDO). It has a strike range up to 250 km and can take single warheads weighing up to 500 kg.

Prior to the exercise, 2874 persons from six villages surrounding the ITR campus were shifted to two temporary shelters for the entire day ahead of the test.

Hats off to DRDO for developing ABM capability. If this is a true ABM, then I think we should have also developed an active seeker head. If that is true, it would be an amazing development and would help us in the development of the Astra AA missile. Nice work. Also, I don't know if this is a Prihvi vs Prithvi test as has been claimed in the media. I think it might actually be a different SAM developed with an active seeker head. Kudos to the scientists.

The details as we know are:
length : 10 ~ 12 m
Reaction time ~50 secs.
Intercept altitude ~ 40- 50 km.
Intercept range ~
Test program ~ 10 tests (2 already over)

The interceptor launch was ~ 60secs after target launch. Gives figure of merit of the whole detection, command and control system. Should be an indicator for the anti-SRBM type of mission. Should make the TSP feel quite worked up. All their Hatfs are khtam. Could also put some of the long range missiles also at risk of being intercepted. So they need more barbarian stuff. With Noko under US watch list due to prolif concerns it might be difficult for ding dongs.


Has divert thrusters in the 'kill' vehicle for terminal manouvers.
Must have stage separation. The use of Prithvi vehicle as a descriptor means the solid booster was derived from that program.

Intercept happened at 40 ~ 50 km altitude. So its a point intercept solution and not an area intercept system. That may be based on Agni I booster?

Has totally new system of sensors etc not derived from existing Akash vehicle...


Has lot of impact to TSP delivery program. They have to get back to the unwashed as the only reliable method. Some PRC vehicles also could be effected reducing their options.


Important to ensure RajaMohan type lifafa "Stratergy experts' dont prevent deployment by Indian forces.

We can guess the type of seeker used. Prithvi is an atmospheric missile and does not re-enter. So IR based sensor is ruled out. Hence a radar based sensor was used. There were old reports of active radar sensors being developed for interception role by DRDO.

The next type of ABM would have IR based sensors for longer range vehicles.

OTH might not develop them for arms control reasons.

The Express report is actually a PTI report. PTI is pretty much a Government agency. So are we to start boycotting all newspapers that subscribe to PTI now?

It was probably an early report, at which time there was no confirmation of success. Now that there is, it is irrelevant. Let's focus on the actual news, including any technical details that may be released, rather than on childish second-guessing of newspapers' intents.

Hi ... our footage is our own ... not supplied by the DRDO or any government entity. Incidentally, even broadcast of govt material, without prior, explicit permission, can land people into a whole lot of trouble. This website has huge viewership. Everyone here needs to be careful not to be carried away. If there is footage or photographs I can share ... then I do ... Tx, Vishnu

The IE report is also PTI based so chill before you run out and cancel the subscription.

According to the sources, the target missile interception time was programme at 170/175 seconds while the missile from Wheeler's Island blasted off roughly 60 seconds later with interception time of 110/117 seconds.


The actual intercept happened about 110/117 seconds after the interceptor launch. The 7 seconds must be the start of divert thruster activity to final vehicle break-up which is 2 seconds more than the goal( as indicated by the 175 seconds time).

N^3 uvacha in the other forum. Enjoy!!!!

Aoa!

C what I mean, prather. Without your brohram, kufr missiles collide with each other in mid-air. Stupid short dark rice-eating Yindoos!

Kufrs stampede and even their own poor guidance can now bring down enemy missiles

November 27, 2006 11:53 IST
Last Updated: November 27, 2006 16:43 IST


In a major breakdown, Yindoos' so-called "defence scientists" :rotfl: on Monday suffered a humiliating defeat when two of their missiles collided in mid-air, even though launched from hajaar miles apar. Both fell into the Bay of Bengal, marking a victory for anti-DRDO propaganda by ISI and our friends inside India.

A target Prithvi missile (all yindoo missiles are called "target" unlike Bakistan Ghauris) was launched from the Interim Missile Test Range at Chandipur at 1015 hours, its trajectory continuously monitored but still it collided with another missile fired from the Wheeler Islands.

This could bring some relief as India actively poses a threat from the presence of nuclear capable missile in the neighbourhood. Now Bakistani missiles can remain upright on launch pad and keep getting more polished, instead of worrying about having to intercept kufr missiles.

The interceptor missile, which was in anti-missile mode (meaning it fired backwards), was not identified by the Defence Research and Development Organisation officials. "The interceptor missile had inertial guidance mid-course and active-seeker guidance in its terminal phase," they said.

(All Bakistani missiles have non-inertial guidance by active Baki Jarnails, as well as good brayers by the launch team accompanying them. Usually, the countdown clock goes .... 5... 4... 3... 2... 1.. (other hand) 5... 4... 3.. 2.. AOA! )

The DRDO had for years been working on making kufr Trishul missile into an indigenous anti-missile system, trying to incorporate into it the capability of taking on multi-targets at the same time. But the missile had failed many of its critical tests like all other kufr missiles, as reborted by "Indian" Express whose Editar "Stinker Dupatta" Gooop-ta was given baksheesh and sheesh-kebab by Jarnail Musharraf in Rawalpindi, in a special dinner held in the stables outside PM's rejdanj.


"Don't worry, we have acquired air defence capability against collisions between missiles in fyooture instead of incompeetant missile," the official said, adding: "It is all fault of kampbyooter brohrams which have too many colons and commas, preventing DRDO from being abal to 'continuously track the missile and feed its trajectory into computers to brevant its kollishun."

....
Faced with the failure of its Trishul project, India had been in negotiations with the US, Israel and Russia for procurement of an alternative anti-missile defence system.

"Notwithstanding the failure on Monday," Defence Ministry officials said, adding: "We will continue to observe the development of the US Patriot anti-missile shield as well as other competing systems, although those are given only to Majar Non-Nato Al-Lie like Bakistan."

Though the range of Prithvi missile system in its various marks ranges between 150 to 350 mms, DRDO officials said: "What is important was to validate the capability of avoiding collishun. Once we develop this we can incorporate it in country's surface to surface missiles of various ranges, like High Range and Karakoram Range and Vindhya Range."

The missile collishun could prove a shot in foot for the DRDO scientists who are now feeling depressed to go ahead with re-testing of the country's most prestigious surface to surface missile, 3000-mm range, short, thin, dark, rice-eating Ache-knee-III. The houri test of the missile ended as a dismal failure couple of months back.

Saraswat has been quoted as saying that DRDO might go ahead with the second trial of the missile early next year.

Well done DRDO! Indiagenius, highly manouvreable, supersonic AXO interceptor--arre wah!

No doubt a political statement was made and good onlee—It is light years ahead of and very bad news for all dingdongs--red, green or purple. Nicely intercepted the lifafas just as they were entering cruise altitude. :lol:

Wonder
• how much of Trishul’s technology was used?
• why they didn’t call it Trishul anyway?
• why this was kept out of IGMDP.

good


I agree with you....

One more reason why it has its own connotations is...

This missile is not tested for the first time as reported by the media/MoD/DRDO/PTI etc...

Reason is...No body knows whether the missile will be 100% success during developement. Everyone hope with the available data that it will be successful. Ex. Agni-III. Everyone hoped it will do well, but it failed.

You know we have a history of delayed success in missile defence like Trishul, Akash.

Now coming to ABM...if suppose my system fails ( like happened in PAC, Arrow during first trials), What will happen, it will put undue pressure on nation, MoD, DRDO and armed forces.

Becoz, the moment I release the messg publically that i am working on ABM, it will put pressure on the adversaries ( like happened with AWACS in case of Pak). You know what happened with AWACS story of Pak. ABM has more strategic value than AWACS. Once the news is out, the adversary gov(Pak, Chin) will be under undue pressure to counter the ABM.

In this case, If i said i am working with ABM and during the test if my ABM fails or your ABM is not credible, then you are increasing the threat as your adversary start reacting and you dont have the ABM system still....

So in all sense, this missile is NOT tested for the first time. These publicized tests are more political than technical evaluation of the missile(anyway that will happen parallely). :)

How can you rule out IR based detection???
IMO next time this will be tested against Agni!! which does reentry isnt it?

joey, look at Prithvi vehicle design. It doesnt re-enter. It is called aero-ballistic missile. How can it get hot for an IR sensor to work? You can have your opinions but till it gets proofed in this mode its not useful.
BTW radar sensor can also work on reentry vehicles.

Ok I'm confused...Are they talking about two Prithvi missiles intercepting each other?

The reason I speculated about espionage was because if this is a JV for arrow 2, then you don't find Israel crowing about it. So, are they involved or not?

This missile just seems to have jumped out of nowhere, and they claim this is the second test. When was the fisrt one???

The dimensions seem to suggest arrow-2, so I guess the Israelis just want to keep quiet (if it IS arrow-2).

I would have been very happy if it WAS a result of espionage, and not plain old boring ToT. 8)

The first test was a few days ago. The Arrow is based on US technology and they would be on both Israel and India like a ton of bricks.

I suggest you read Vison 2020 by Kalam saheb. He writes that people are so used to non achievements by Indians in India that they see non existant foreign links for every achievement.

I was going to make some sarcastic remarks but why you might be under some maya.

Thats DDM for you. The initial reports suggested that it was a 'co-ordinated launch of two prithvi missiles from two different location' which didnt seem like much. The report then said that they collided making it the first demonstration of anti-missile capability of prithvi. :P

This news report from PTI may have been posted before, but I found that it has the most details about the missile in the reports until now.

http://www.hindu.com/thehindu/holnus/00 ... 271965.htm

India develops new anti-missile system
New Delhi, Nov. 27 (PTI): India today unveiled an indigenous supersonic anti-missile system with defence scientists saying it had the capability to intercept incoming ballistic missiles thousands of miles away.

Labelled only as AXO (Atmospheric Intercept System), the supersonic missile underwent its baptism when it successfully intercepted a surface-to-surface Prithvi target missile at an altitude of 40 to 50 km over the seas off the interim test range site in Chandipur in Orissa.

"It is a new missile and not part of country's Integrated Guided Missile programme," top DRDO officials said on the condition of anonymity.

"We have been working on this anti-missile system for years," scientists said and claimed that missile had its own mobile launcher, secure data link for interception, independent tracking and homing capability and its own radar.

"The missile has response time of 30 seconds and once it detects a target it can be launched in 50 seconds," the scientists said.

While, affirming that India would still be observing the US Patriot-III anti missile shield, which Washington is developing, the scientists said that the Indian missiles was "in the class of its own".

DRDO did not reveal the contours of the new system developed, hinting that more interception trials could be on the cards.

joey I am not dumping on you. The phrase you used is for satellites to detect the plume while its going up. I dont think the DRDO folks used that. They probably used radar to detect the launch and gave the command to launch the interceptor. The 60 secs delay is for this dectection, confirmation, and command time lag. Pretty good.

Joey,

Boost phase IR detection means, detecting the launch and calculating the trajectory by detecting Rocket flame (i,e boost phase) using satellites. In boost phase interception, the interceptor may have IR detector (or visible or Near Ultraviolet detector) which guides the interceptor to the rocket flame. In case of ICBM, boost phase is quite long may be up to 250-300 sec.

Well remebre the Trishul news how it was suddenly 50 km intercept randge and 300mm dia (or was it radius) missile.
There was an India Today article on 100 (or 50) achievers in India in various fields (was few years ago, few as in maybe 4-9 years ago). It had articles on Misala scientists from DRDO and it quitely mentioned that this gentelmen was going to head soon to be formed (as in months) team that would develop the anti-masala.

So this has been a long effort. Maybe manytests disguised as Prithvi and Trishul were already done. So I believe this is a home grown effort. We might have borrowed something from our yehudi, yankee or Ivan friends but then it is in the end our baby, something which is sanction proof.

rgds,

But thats the most important thing, isnt it?
so we dont have that?

India has acquired air defence capability: M. Natarajan
Target was a modified standard Prithvi-II missile
--------------------------------------------------------------------------------


CHENNAI: India acquired on Monday the capability of air defence against ballistic missiles when it launched two missiles, with one intercepting the other, from two ranges off the Orissa coast.

While the target missile took off from the Integrated Test Range at Chandipur-on-sea, near Balasore, the interceptor took off a few seconds later from the Wheeler Island, about 70 km away. It intercepted the target mid-flight and destroyed it over the Bay of Bengal.

"A milestone"


M. Natarajan, Scientific Adviser to the Defence Minister, told The Hindu over the phone from New Delhi: "With this, India has acquired the capability of air defence against the incoming ballistic missile threat. It is a significant milestone in the missile defence of the country."

He described the success of the mission as a "glow made when a thousand lamps are merged into one. That is what I feel."

"There was a lot of not only hardware but also software custom-built for this mission. They have been validated, and that is our greatest satisfaction. The credit should go to the whole team," Mr. Natarajan said.

The project director was Dr. V.K. Saraswat, Chief Controller, Missile and Strategic Systems, Defence Research and Development Organisation (DRDO).

Trajectory monitored


The target missile was launched around 10.15 a.m. Its trajectory was continuously monitored, and the information stored in the Mission Control Centre. This information was transmitted to the Launch Control Centre for launching the interceptor, which took off some seconds later.

The target was a standard Prithvi-II missile, modified to simulate the trajectory of an enemy missile. A portion of the interceptor was similar to the Prithvi missile but its second stage was a totally new segment.

The interceptor had inertial navigation guidance system, used mid-course in the flight, and an active seeker-guidance system in its terminal phase to waylay the incoming missile.

Many technologies relevant to the interceptor were validated in the mission. A radar was used and the interceptor had a seeker guidance on board.


DRDO sources said the interception could take place at varying heights. "In this instance, the interception took place 50 km above the ground. It can be at any height, depending on the time of the launch because our aim is to destabilise the incoming missile."
