The current US ABM program is strictly conventionally-based.

"The first deployments in Europe began in 1959[5] and the last nuclear-armed Nike Hercules missiles in Europe were deactivated in 1988.[6]" See MIM-14 Nike-Hercules - Wikipedia, the free encyclopedia

The old Nike nuclear-tipped anti-missile missiles were deployed in 1959. Nike technology is 50 years old. Do you really believe that China does not possess 50 year old US technology?

Well, US is unable to develop with its modern technology a fool-proof ABM, you are talking about use of a 50 yr old technology which is abandoned by US will be used by China to shoot down ballistic missiles is far fetched :wink:. Moreover, presence of such nuke tipped missiles with China is a speculation, there is no conclusive proof that they possess them. So, lets not get into hypothetical debate about probably non-existent missiles.

Also this thread is about Indian missile development. Let's stick to the topic. Anymore off-topic posts will be deleted.

Nuclear capable ballistic missile Prithvi-2 successfully test fired - India - The Times of India

BALASORE: India's highly sophisticated and nuclear capable short-range ballistic missile (SRBM) Prithvi-2 was successfully test fired on Monday from the Integrated Test Range (ITR) at Chandipur near Balasore in Orissa.

Sources in Defence Research and Development Organisation (DRDO) had earlier said that the test would be part of the user's trial.

The test was conducted by a special contingent raised by the Indian army.

Prithvi-2 missile is single stage liquid propelled and is equipped with inertial navigation system. The missile is about nine meters in length and one meter in diameter. The missile can carry conventional or nuclear warheads.

India's Missle Revolution


Though India, perhaps is the first country in the world where missiles were used in war (by Tipu Sultan against the British), India woke up to its potential much later. China, in order to ascertain its No. 1 position in Asia, created a strategic black hole for India—Pakistan. It utilized the pathological Pak-hatred against India to its full advantage. China helped Pakistan in its missile and nuclear programs. Pakistan bartered its nuclear know-how for North Korea's long range Nodong missile technology. Pakistan began to develop sophisticated missiles. India, on the other hand, was reeling under heavy sanctions. Besides the traditional friend Soviet Union was interested in selling weapons, not technologies. But to meet the immediate threat perceptions and defend its territory, India had to build missiles. Two decades ago, the then defense minister, R Venkataraman sanctioned 388 crores for India's Integrated Guided Missile Development Program (IGMDP) under which five missiles-Agni, Prithvi, Trishul, Nag and Akash were to be developed. The program was designed keeping in mind the Pakistan factor. The project was launched by Dr.V.S.Arunachalam, scientific advisor to the defense minister on July 27, 1983.

As India detonated its nuclear devices in May, 1998 and declared itself a nuclear-weapons country, the domino effects in the fields of diplomacy and technology began to take place.

A new polarization was going to take shape. The contemporary BJP-led NDA govt. surprised the world by supporting the controversial US National Missile Defense initiative. Post 9/11, though the USA counted upon Pakistan as a frontline ally in its war against terror, the USA was suspicious about Pakistan's double dealing. Later, the NDA govt. signed Nest Steps in Strategic Partnership (NSSP) with America which became the first stepping stone of a robust Indo-US relationship. The American govt. hinted at de-hyphenation of the India-Pakistan theme and showed a policy shift in favor of India by permitting Israel to sell the most powerful AWACS (Airborne Early Warning and Control system) in the world- the Phalcon. The US offered PAC 3 (Patriot Advanced Capability 3) anti-ballistic missile system to India. It also offered the F16, F18 and above all the F35 Joint Strike Fighter. It also engaged with India in extensive military exercises. Thereafter, the UPA govt.came to power and signed a ten-year defense agreement with the USA. Later the Nuclear Deal signed between the USA and India promised to end India's nuclear isolation. The USA promised to help India become "a major global power" Thus the USA stopped objecting to India's military ambitions and even allowed the Indo-Israel defense relationship to flourish. Israel became the second largest arms supplier to India, the first being Russia. India gained immensely from Israeli expertise in electronic warfare systems like radars, sensors, night-vision equipments, etc. In the field of missiles and UAVs the two countries began to collaborate extensively. India imported from Israel Green Pine early warning and fire control radar systems. They could track any hostile missile within a range of 500Km.

But several factors contributed to the Indo-Us bonhomie. First, India became one of the fastest growing economies of the world. The Goldman Sachs report predicted a rosy future for India secondly China's spectacular rise became a great concern for the USA. China's rapid military modernization coupled with its space aspirations and spectacular economic growth, forced the USA in the balance of power game. India with its vast military, huge manpower and economic prowess could become the counter weight to China. Furthermore, the western press began to hail India as a science supper power. The country in the field of software made huge strides. India succeeded in making its own supercomputer. The indigenous cryogenic engine was only a matter of time. In the field of space, India was striding ahead. In the field of defense, India's success in Nishant UAV, pilotless target aircraft Lakshya and Akash anti-missile system caught the US attention.

India's self-confidence level was high. The NDA govt. turned the Indo-Russian relationship from a buyer-seller to a join development and production partnership. The Brahmos supersonic cruise missile agreement was the result of India's self-confidence. The joint development and production of the 7000Km Sukhoi 30MKI aircraft was also undertaken.

India's Pak-fixation was replaced by its determination to challenge China. China's listening post in the Burmese Coco islands, its engagement in building the Pakistani Gwadar port, its meddling in Nepal and Sri Lanka, its strategic alliance with Bangladesh, its intense military engagement with Pakistan, its rapid military modernization, its repeated incursion into Arunachal, its claim over Arunachal, etc forced the Indian policy makers in search of an strategic antidote. Besides, the Indian Ocean being a theater of power struggle for several powers and a possible transit of several terrorist organizations, the policy makers were worried.

The strategists conceived of Agni 2, 3 and 4 to deter China from any misadventure. Again China's A-Sat (Anti-Satellite) test January last year pushed the strategists even further in search of a dedicated aerospace command. They envisaged the necessity of a space- based anti-missile system.

India's missile development was certainly the result of the untiring efforts of the DRDO. But the aforesaid factors also contributed to the present state of affairs of the missile technology. The Indian missiles and the command and control systems are certainly the byproduct of myriad factors shaping the Indian defense history.




India's Missiles


The IGMDP had five parts—Agni, Prithvi, Trishul, Nag and Akash. Agni was a technology demonstrator. The moment the technology demonstration of Agni with three flights was completed it was taken out of IGMDP. The Agni I, II and III were separately sanctioned. Agni I is Pak-specific and has a 700Km range. It's a single stage solid fuel ballistic missile. Agni II covers 2000Km and Agni III is a China specific ballistic milssile with a range of 3500Km. Both Agni 2 and 3 are two stage and all solid fuel missiles.

Agni III is not only a missile but a system for the future with which various configurations can be developed. It weighs 48.3 tons and 16.7mts long. It has a diameter of two meters and can carry nuclear warheads weighing 1.5tons over a distance of 3500Km. Agni III, like Agni II is rail mobile. The missile uses fire and forget principle. The scientists are now developing Agni IV with a range of 5500Km. Agni IV covers all the major cities of China except Beijing. Agni IV will bring all the major cities of China within its range. It will be a III stage missile with the same weight as Agni III. All the three stages will be powered by solid propellants. The missile, unlike Agni II and III, will be road mobile. All the Agni versions can carry nuclear warheads.

The Prithvi missile is a Pak-specific 350 Km shorter range N-Capable ballistic missile. It has a naval version too, called Dhanush. A modified Prithvi was used for anti-ballistic missile test also. The army has accepted the Prithvi missile.

Nag is a third generation anti-tank missile by summer 2008, Nag related work will be completed .Then the IGMDP will be over.

Trishul is a 9 Km range missile which was meant to replace the 1970s vintage Soviet made Osa short range SAM.The army used the Osa to protect its strike columns from attack helicopters and aircraft. the IAF to protect its air fields and vital installations and the navy to protect its warships at sea from aircraft and anti ship missiles. Though the DRDO is optimistic about its induction, its inordinate delay and initial failures forced India to look for the Israeli Barak. Though it was successfully tested in 2006-07, the future of Trishul is still uncertain.

Akash is a medium range surface to air missile (SAM). Akash is a state of the art multi-target handling surface to air missile system. Only three or four countries such as the US, Russia and France have developed this type of system. Akash uses solid fuel. No country except Russia uses solid fuel in tactical missiles, not even the US. Here the system can be called to be superior to the US Patriot system. With the development of Akash the Indian scientists mastered two unique technologies-multifunction phased array system integration and integration of ram-rocket propulsion, aerodynamics, structure and control. The system also has an application called weapon locating.

Astra is an air to air short range missile developed indigenously by DRDO. It is an efficient weapon released from a vital aircraft and has a striking range of 10-25 Km. India is the sole non-NATO country, except Russia to possess such a sophisticated system.

Sagarika or K-15 is a light, miniaturized and canisterised 700 Km range SLBM.It is 6.5m long and weighs about 7tons. It can carry nuclear warhead up to 600kg. It is a single stage missile powered by solid propellants. It has advanced avionics, propulsion, control and guidance and inertial navigation systems. With the launch of this missile from a submerged pontoon India has joined the select club of countries which includes Russia, the US, France, China and the UK with submarine launch capabilities.

The Indo-Russian Brahmos is the sole supersonic cruise missile in the world. With a range of 300 Km running at Mach 2.8, it can carry conventional warhead of 225 Kg. It is a versatile missile which can be deployed in warships, submarines, aircraft and land-based launchers. It can be used to target high value sea and land targets like warships, bunkers, air bases and railheads. India fired a hypersonic interceptor missile that intercepted and destroyed an incoming target missile in a direct hit over the Bay of Bengal on Dec. 6,2007. The interception took place at an altitude of 15Km, in what is called the "endo atmosphere" The "hit to kill" success catapulted India into the elite club comprising Russia, the US and Israel, all of whom have missiles that can block incoming ballistic missiles.

In November 2006, India demonstrated its, air defense capabilities against incoming missile when it shot down an "enemy" missile in the exo-atmosphere, that is 50Km above the earth. A modified Prithvi missile was used for the purpose using terminal guidance system.

Besides, India has bought 9Km range Barak anti-missile system for the navy. Each system has the capability to fire a minimum of eight interception missiles. This is a point defense system which is the first stage in acquiring a comprehensive theater missile defense system.

In the field of rocket launchers too India occupies a great position. On Feb.29, the Indian army has inducted Pinaka which can be fitted with nuclear warheads. It is a state of the art weapon for destroying or neutralizing enemy camp concentration areas, communication centers, air terminal complexes and gun or rocket locations.Besides the Russian Smerch mobile multiple rocket launcher, which carpet bombs targets 90 Km away is also with the Indian army. The army needs this for destroying targets spread over a wide area.


The Future of India's Missile Development Program


Post Pokhran II, India was fixated with nuclear bombs or warheads. But gradually the policy-makers realized that the delivery systems were even more important than the nuclear warheads because, nuclear bombs will hardly be used in the future wars. But the missiles will and can be used in all the wars. So the policy makers tended towards making an effective command and control system because it is necessary not for nuclear war only but also for conventional warfare to detect and destroy enemy missiles and weapon systems. India, till date has made an astonishing advancement in the field of command and control system. In some ways or the other, it has stridden ahead even of Russia, the US and China. If such a pace continues, India will outperform China in all the missile related technologies and radar systems.

The future holds enormous promises India plans to test launch the Agni 4 missile with a range of 5500 Km. This will cover all the major cities of China within its range. The missile will be much more sophisticated and it will be road mobile to avoid vulnerability. This will be a 3 stage missile with all solid fuel. Furthermore an SLBM of a similar type missile will be developed to integrate it with the indigenous Advanced Technology Vessel (ATV), a euphemism for nuclear submarine. This type of SLBM will be the most reliable deterrence mainly against China. Furthermore, several new technologies can be used with such a vehicle.

The submarine version of the Brahmos supersonic cruise missile is to be tested soon. The submarine version must be much more lethal in nature than it's all the versions. The development of an airforce version of the Brahmos which will be integrated with the 7000Km. Sukhoi 30 MKI is also underway. Furthermore, the Indo-Russion Brahmos Aerospace Private Ltd. Plans to field a hypersonic Brahmos running at Mach 8 by 2010. It will be 1000Km. range. Such a cruise missile must be an asset for the Indian military.

India's indigenous ballistic missile defense system has got a boost with the successful endo and exo-atmospheric tests. Such tests have assumed an unexpected significance in view of the recent anti satellite tests conducted by China and the US. Even the scientists are confident of detecting and destroying not only incoming missiles but also wayward satellites. The former President and missile technologist APJ Abdul Kalam has asserted that India can destroy any foreign object at an altitude of 200 Km.

India, after the US, successfully conducted a hypersonic test. The hypersonic technology can take India on the highest plane of missile technology.

The UPA govt. last year cleared a gigantic Rs. 10,000 crore project with Israel to develop an advanced medium range surface to air (MR-SAM) missile system capable of detecting and destroying hostile aircraft, missiles and spy drones at a range of 70Km. In reality the MR-SAM project is an extension of the ongoing DRDO-IAI project launched in Jan.2006 to develop a supersonic 60Km. Barak NG (Next Generation) missile defense for the navy.

India wants to develop a dedicated aerospace command. But till date, India does not have a dedicated military satellite network. India plans to use the Russian GLONASS (Global Navigational Satellite System) for the purpose. Besides, India is developing its own GPS version- the Indian Regional Navigation Satellite system. ISRO will launch seven satellites to build the system. Besides, the Indo- Israeli space cooperation has reached an unexpected high. With the successful launch of the Israeli spy sat, Tecsar, the bonhomie seems to fructify several projects in the future. India is interested in buying the Israeli radar imaging satellite design. The synthetic aperture radar systems which can look through day and night, rain and cloud are also on the Indian wish list.

The DRDO scientists have succeeded in making light composite materials for making missiles. They will make the missiles lighter and will help the missiles to carry much more warheads. The scientists plan to develop smart, light and miniaturized precision guided missile which will be more accurate and can be carried in aircrafts. Hypersonic vehicles, miniaturized missile systems, nano-technology, very large systems integration and homing guidance have been identified by Research Center Imarat(RCI) as the thrust areas for development of futuristic missiles.

The strategists think the future wars will be network centric, not platform centric. IT will play a major role in future warfare. Hence they have suggested building a network of UAVs, satellites, radars, sensors and so on.

Weapon system like JDAMs (Joint Direct Attack Munitions) and UCAVs will necessitate newer types of missiles. Besides, Indian expertise in software will yield sophisticated missiles. Multiple warhead missiles can be made in the future too.

The offset provision and the participation of the private companies in the defense sector in greater number is going to herald a revolution in the Indian defense history.

If the policy planners and strategists follow their course with unwavering resolve, the country, in the field of missile, will be a pioneer. There is no doubt about it. Besides if a direct and fruitful Indo-US joint venture in this field fructifies, India will certainly be a missile superpower.

Nuclear capable Prithvi-II test fired successfully - Express India

The missiles, testfired this morning, had different ranges. They have been designed to operate with both liquid and solid fuels, and were capable of carrying both conventional and nuclear payloads, they said. The trials were conducted in the presence of Scientific Advisor to the Defence Minister, V K Saraswat, top scientists and army officers. The user trials of Prithvi-II was last carried out on April 15 this year also from Chandipur.

Missile breakthrough: Agni-V poised for a global reach

Missile breakthrough: Agni-V poised for a global reach

Hyderabad: The Advanced Systems Laboratory (ASL) in Hyderabad, which develops India’s strategic (long-range, nuclear-tipped) missiles, has dramatically increased the options for its forthcoming Agni-5 missile by making it highly road-mobile, or easily transportable by road.
An upgraded version of the Indian Agni missile, which has nuclear capability and the range to reach deep inside neighboring territory, is seen on its mobile launch pad on Wheeler Island in the Bay of Bengal before its successful test Sunday, April 11, 1999. The test came despite U.S. requests that India hold off on development of its nuclear program. (AP Photo/HO)

That enables the Agni-5 to reach targets far beyond its stated 5,000-km range by quickly moving closer to the target. In a hypothetical war against, say, Sweden, an Agni-5 launcher, stationed near Bangalore, would be unable to strike Stockholm, 7,000 km away. But moving by road to Amritsar would bring Stockholm within range.

Similarly, moving the Agni-5 to northeast India would bring even Harbin, China's northernmost city, within striking range. From various places across India, the Agni-5 can reach every continent except North and South America.

The Agni-5 will be the first canisterised, road-mobile missile in India's arsenal, similar to the Dongfeng-31A that created ripples during China's National Day Military Parade in Beijing on October 1. India's current long-range missile, the Agni-3, a non-canisterised missile, can only be moved with difficulty from one place to another.
In many other respects, the Agni-5, which is scheduled to make its first flight in early-2011, carries forward the Agni-3 pedigree. With composites used extensively to reduce weight, and a third stage added on (the Agni-3 was a two-stage missile), the Agni-5 can fly 1,500 km further than the 3,500-km Agni-3.

"The Agni-5 is specially tailored for road-mobility," explains Avinash Chander, Director, ASL. "With the canister having been successfully developed, all India's future land-based strategic missiles will be canisterised as well".

Made of maraging steel, a canister must provide a hermitically sealed atmosphere that preserves the missile for years. During firing, the canister must absorb enormous stresses when a thrust of 300to 400 tonnes is generated to eject the 50-tonne missile.

Canister technology was first developed in India for the Brahmos cruise missile. But it was the K-15 underwater-launched missile, developed here in Hyderabad for India's nuclear-powered submarine, INS Arihant, which fully overcame the technological hurdles in canisterising ballistic missiles.
nother major technological breakthrough that will beef up the Agni-5 is ASL's success in developing and testing MIRVs (multiple independently targetable re-entry vehicles). An MIRV, atop an Agni-5 missile, comprises three to 10 separate nuclear warheads. Each warhead can be assigned to a separate target, separated by hundreds of kilometres; alternatively, two or more warheads can be assigned to one target.

"We have made major progress on the MIRVs in the last two years," is all that Avinash Chander is willing to say on the subject.

Nevertheless, extensive testing still lies ahead for this highly complex technology. MIRVs will be deployed on the Agni-5 only after another 4-5 years.

While MIRV technology is similar to launching multiple satellites through a space rocket, a missile requires far greater accuracy. A satellite would be considered in correct orbit even it is a kilometre higher or lower than planned..
But each warhead in an MIRV must impact within 40 metres of its target. With such high accuracies, even small nuclear warheads are sufficient for the job.

Strategic planners consider MIRVs essential, given India's declared "no first use" nuclear policy. Even after an enemy has hit India with a full-fledged nuclear strike, destroying or incapacitating much of the strategic arsenal, a handful of surviving Indian missiles must be capable of retaliating with massive and unacceptable damage. Multiple warheads on a handful of Agni-5 missiles would constitute such a capability.
MIRVs also enable a single missile to overwhelm the enemy's missile defences. Tracking and shooting down multiple warheads are far more difficult than intercepting a single warhead.

Providing each warhead with the capability to manoeuvre, and dodge enemy interceptor missiles, increases survivability further. The MIRV warheads are also being given electronic packages for jamming enemy radars.

well i dont wanna repeat the article for which i have thanked the poster,

as for as im concerned india has " arrived " in this area of technology. Of course more need ot be done , praps even much more ? but well done to the orgs responsible for the development of this.

why are these AGNI-5 launch dates being moved out further and further - 2009, 2010, and now 2011.

Its seems like you can never get a straight story about anything from these guys in the media, or is it the DRDO ??

After every test, they say that everything worked perfectly - 6 months later you hear about more tests, and then they say its because the earlier test 6 months ago did not exactly go according to plan.....even though at that time it was reported to be "flawless".

Isnt it better to just level with the media, rather that changing stories and dates every 6 months and losing the credibility. Or better yet....if you cant keep your dates, then just shut-up until you launch it.

There is more then meets the eye. I remember lot of members criticizing multiple tests of Prithvi when other countries declare such missiles operational only after 1-2 tests. Now once ATV is launched we hear news about multiple K 15 tests how? The news is masqueraded hope this cleares the point. And DRDO is not the final authority to decide about the tests it is the political leadership which gives the final go ahead about the testing so it is not fair to blame DRDO for date saga

Should Indian missile development stop at Agni-5? Or is it necessary to keep developing a longer range missile to "reach every continent," including North and South America?

Prithvi-II missiles successfully test-fired

Event establishes Army’s capability to attack multiple targets simultaneously

Both missiles have a range of 350 km: DRDO

Variants developed for Army, Air Force, Navy


HYDERABAD: Two nuclear-capable, medium range surface-to-surface Prithvi-II missiles were successfully test-fired within a few minutes of each other by the armed forces from the Integrated Test Range (ITR), Chandipur, off the Orissa coast on Monday.

According to Defence Research and Development Organisation (DRDO) sources, both missiles had a range of 350 km and were launched as part of the operational exercises by the Strategic Forces Command. The missiles were fired from two mobile launchers at the ITR around 10.30 a.m.

The successful test-firing established the Army’s capability to attack multiple targets simultaneously. Both missiles met the full mission objectives, the sources said.

The missiles were flight-tested against two targets, located 350 km away from the launch pads.

The advanced inertial guidance system of the projectiles enabled them to hit the targets within a few metres of Circular Error Probability (CEP).

Two naval ships anchored at target points tracked and monitored the missiles hitting the targets accurately, while the radars and electro-optical systems located along the east coast observed the flight path along the trajectory.

‘Major milestone’

“It is a major milestone for the ITR as it showed the capability for simultaneous tracking of two missile systems while they are flying,” the sources said. Both were in flight around the same time for a few minutes.

Prithvi-II is equipped with features of manoeuvrability to deceive the enemy defence systems. The missiles were picked from the stock of the Strategic Forces Command.

Nine-metre tall Prithvi-II is a single stage liquid fuelled missile and has a diameter of one metre. It is capable of carrying a 500-kg warhead.

The DRDO developed three variants of Prithvi to meet the requirements of the Army, the Air Force and the Navy (Dhanush). The project, first one developed under the DRDO’s Integrated Guided Missile Programme, was initiated when the former President, A.P.J. Abdul Kalam, headed the organisation.

Scientific Advisor to the Defence Minister V.K. Saraswat, Commander of the Strategic Forces Command Lt. Gen. B.S. Nagal, Advanced Systems Laboratory Director Avinash Chander, and Bharat Dynamics Chairman and Managing Director Ravi Khetarpal witnessed the test-firing.

it is only logical. you should remember that users(SFC) will continue to test even later too. that is only to reassure themselves that all the missiles and the subsystems in their inventory are indeed working fine, besides they get to familiarise themselves with the operations.
the missles need not only validification but repeatability. that is the point.

A small stage called SUM is supposed to add 1500Km to 3K A3 missle. Who is stopping us to add a big "SUM" or another stage to boost it further. And who is stopping us to test an A6 and call it an A5

If we can reach the moon and launch 10 satellites in one shot don't believe for one second that anybody is out of our reach.

India's developing mutliple-warhead missile

New Delhi, October 16, 2009

This one is on the lines of free-market commercials: Ask for one and get at least four free! The difference is that it is not a shirt or a pair of jeans. It's a single rocket capable of delivering multiple warheads - even non-conventional nuclear systems - at different targets.

The country is on the verge of getting one as the Defence Research and Development Organisation (DRDO) is validating technologies that will help India deploy multiple independently targetable re-entry vehicles (MIRV) on its missiles.

Currently, the country has missiles that can deliver only one warhead at a time. The defence research establishment has confirmed that it has made significant progress over the past few years in developing an indigenous technology for the single-rocket-multiplewarhead system. In another three-four years, this ultimate war machine will be ready.

The DRDO says the platform for re-entry vehicles would be different from the indigenously developed Agni series of missiles. Since it would be precision device, sources said the guiding system would require a high degree of accuracy to offset even a small circular error of probability or a negligible deviation from the intended target.

Another reason for this overbearing inclination for detail and accuracy is that the destructive potential of smaller warheads on multiple vehicles is low. Hence, these warheads will have to hit the intended targets at the accurate point and optimise the damage. That apart, the scientists will have to miniaturise the size of the warheads and develop a superior guidance system.

The MIRV system is not a new concept. Senior analyst G. Balachandran of the Institute of Defence Studies and Analyses said the technology was conceived in the early 1960s by the US to enhance the limited capacity of its nuclear submarines carrying ballistic missiles.

It triggered a major escalation of the arms race between the US and Russia (then USSR) in the Cold War period. The Soviets retaliated by developing a similar technology but placing the warheads on larger rockets. This enabled them to put more warheads into one missile.

Eventually, the two countries signed several strategic arms limitation agreements, reducing the number and weight of the warheads.

The Indian MIRV could also kick up a storm on whether it is against the principle of "nuclear restraint" that guides the country's nuclear doctrine.

Senior journalist Praful Bidwai, also an anti- nuclear activist, said the move would "escalate a disastrous arms race with China". In 2002, China successfully tested its first MIRV - to offset the advantage the US enjoyed with its American National Missile Defence System.

Bidwai said China would surely view the Indian development as threat. "It also strikes at the root of the concept of minimum, credible deterrence as multiple warheads on a missile would surely hike the Indian arsenal manifolds." But Balachandran and Air Commodore (retired) Jasjit Singh, who is now the director of the Centre for Air Power Studies, begged to differ.

"Escalation is a condition that the other party denotes on the basis of its perception. If a single missile delivers multiple warheads, it actually reduces the number of launch vehicles," Singh explained.

Prominent strategic analyst K. Subrahmanyam said the multiple warheads would increase the survival chances of the weapons in case of a nuclear attack.

DRDO to launch series of missiles​

CHENNAI: In the next three to four months, the Defence Research and Development Organisation (DRDO) will be launching a series of missiles “both in the ballistic missile defence area and the strategic side,” according to V.K. Saraswat, Scientific Adviser to the Defence Minister. These will include Prithvi and Agni missiles, and an interceptor missile which (the interceptor) forms part of India’s quest to build a ballistic missile defence (BMD) shield. An advanced version of Prithvi-II was already successfully test-fired on October 12.

Dr. Saraswat, who is also Director-General, DRDO, said: “These are major activities. They are all planned in the next three to four months. All these missiles have to undergo validation, verification and training for the user [the Army]. This is the main purpose of these missions and they will give you confidence in the reliability and robustness of the systems.”

Under the BMD shield, the DRDO will fire an attacker missile which will be ambushed in its flight path by an interceptor missile. This would be an “endo-atmospheric mission wherein we are extending the altitude of interception to 30 km.,” he said.

The DRDO had already successfully intercepted an incoming “enemy” in the endo-atmospheric region at an altitude of 15 km. on December 6, 2007. The DRDO was now going for an interception at an altitude of 30 km.

Dr. Saraswat described it as “a difficult mission because the same interceptor missile has to perform manoeuvres at higher altitudes where the density of the atmosphere is low.” So the manoeuvres became difficult.” Certain modifications, therefore, had been done on the interceptor missile. The DRDO was also integrating “a unique directional warhead” developed by its laboratories into the interceptor. “It is called P-charge [projectile charge] warhead which can penetrate thick steel and cause damage with a high hit [repeat hit] density. That means the number of holes you create per unit area is very high,” he explained. This mission would validate the DRDO’s new command, control and communication software which was being upgraded to monitor “space-objects such as satellites and to discriminate between actual threatening objects and decoys,” he added.

The DRDO is developing a new Prithvi interceptor missile codenamed PDV. It will be a two-stage missile and both the stages will be powered by solid propellants. It will have an innovative system for controlling the vehicle at an altitude of more than 150 km. “We expect to have trials of this early next year,” the Scientific Adviser to the Defence Minister said.

ok after a long time some info:

Astra air-to-air missile to make its first flight

To add punch to IAF’s fleet of Sukhoi, Mig-29, Mirage-2000, Tejas.

Veteran fighter pilots lament the end of the dogfight, the evocative name for a twisty, sky-ripping, adrenaline-packed aerial duel, in which the winner gets behind his opponent and shoots him down with a burst of cannon fire.

Today, it is less about flying skill, cold nerve and highly-responsive aircraft; the modern-day dogfighting ace is an airborne video-game expert who uses radar to detect his foe at long ranges, and launch a beyond visual range (BVR) missile even before his victim realises that the engagement has begun.

Just days from now, a Sukhoi-30MKI fighter will take off from an Indian Air Force (IAF) base, an Astra missile fitted on its wing. This will be the first-ever flight of this indigenously developed BVR missile, which the IAF hopes will add punch to its fleet of Sukhoi-30MKI, Mig-29, Mirage-2000 and Tejas Light Combat Aircraft (LCA) fighters.

The Astra, built by the Defence R&D Laboratory (DRDL), Hyderabad, will allow IAF pilots to hit enemy aircraft up to 44 km away, at altitudes up to 20,000 metres. Improving on that will be the Astra Mk II, with a longer range of 80 km.

The Astra incorporates many cutting-edge technologies. Here is how an Astra would take on an enemy fighter: an IAF fighter’s radar picks up the target; the pilot launches an Astra missile. A high-energy propellant quickly boosts the missile to several times the speed of sound. At ranges beyond 15 km, the Astra cannot “see” its target, so the IAF fighter guides the missile, relaying the target’s continually changing position over a secure radio link. Once it is 15 km from the target, the Astra’s onboard seeker picks up the target; after that the Astra homes in on its own.

At this point, the target would start turning and diving to throw off the missile. But the Astra manoeuvres better, and moves much faster, than even the most agile fighters. A radio proximity fuse measures the distance to the target. When the target is within 5 metres, the Astra’s radio proximity fuse detonates its warhead, sending a volley of shrapnel ripping through the enemy fighter.

Most of these technologies have already been proven. The propulsion system, the data link between the aircraft and the Astra, the radio proximity fuse, the onboard computer, the inertial navigation system and other key technologies were developed at the DRDO’s missile complex in Hyderabad.

The Astra’s seeker is still imported from Russia, but the DRDO hopes to develop one.

The forthcoming test with a Sukhoi-30MKI is called a “captive flight trial”; it will evaluate whether the Astra can withstand the physical stresses of supersonic flying and high-speed manoeuvring. Early in 2010, a “captive-II flight trial” will check whether the Astra’s avionics are properly matched with those of the Sukhoi-30MKI. The fighter should receive the missile’s signals; and the Astra should receive the aircraft’s commands.

“Matching an Indian missile with a Russian fighter’s avionics has turned out to be a complex task”, explains Mukesh Chand, one of the Astra’s key developers, “But the Astra will be much better integrated with the Indian Tejas LCA.”

Only in October 2010, after all the Astra’s systems are certified airworthy, will a live Astra be fired from a fighter. But the project scientists are confident; in a September 2008 test in Balasore, Orissa, a ground-launched Astra shot down an electronic target, validating many of the most complex technologies.

A drawback in the Astra remains its high weight; even a heavy fighter like the Sukhoi-30MKI cannot carry the missile on its wingtip stations. In comparison with the Astra’s estimated 150 kg, other BVR missiles like the Israeli Derby weigh around 100 kg only.

Nevertheless, the IAF believes the Astra will usefully supplement India’s inventory of BVR missiles. The Russian R-77 Adder, which arms India’s Russian aircraft fleet, faces worrying questions about its reliability. And the R530D missile, carried by the Mirage-2000, is nearing obsolescence.
