Guided missiles of India

The use of rockets in India, for warfare, dates back to the 18th century. These rockets (also known as Mysorean rockets) were the first iron-cased rockets that were successfully deployed for military use. The British reverse-engineered these and introduced the technology to Europe (see Congreve rocket). When India became a British colony, scientific R&D in India was restricted and military science in India naturally lagged.

Research in missile technology resumed again in the late 1950s under the political leadership of Jawaharlal Nehru, independent India's first prime minister. Successive Indian government after his, continued providing consistent political backing to the program. In 1982, India's political and scientific leadership, which included prime minister Indira Gandhi, Defence Minister R. Venkataraman, V.S. Arunachalam (Scientific Advisor to the Defence Minister), Dr. Abdul Kalam (Director, DRDL) accelerated and gave new dimensions to the missile program, under the 'Integrated Guided Missile Development Program' (IGMDP). The IGMDP is one of India's most successful defence research project, as all the missiles – Prithvi, Akash, Trishul, Nag, Agni – have been successfully tested and inducted by the Indian armed forces.

After the end of the IGMDP (on 8 January 2008), India now develops all its current and future missiles as independent projects, and wherever possible, with private industries and foreign partners. (Brahmos is an example of one such successful collaborative project, between India and Russia).

History


Mysorean rockets were the first iron-cased rockets that were successfully deployed for military use. Hyder Ali, the 18th century ruler of Mysore, and his son and successor, Tipu Sultan used them effectively against the British East India Company. Tipu Sultan's military manual (called Fathul Mujahidin) even advocated that 200 rocket men should be assigned to each Mysorean Kushoon (brigade). These rocket men were also trained to launch the rockets. In addition, wheeled rocket launchers capable of launching five to ten rockets almost simultaneously were used in war.

It was the world's first use of rockets for fighting modern wars. The British successfully reverse engineered and developed this rocket technology further (See Congreve rocket). After India was conquered, scientific research and development was constrained to further the British interests and military science in India naturally lagged.

Post-Independent India
Democratic India's missile programme dates back to the late 1950s, when Jawaharlal Nehru was the Prime Minister of India and Dr. D. S. Kothari was the Scientific Advisor to the Defence Minister.

Motivated to strengthen its defences after the 1962 Sino-Indian War, and the prevailing international scenario of the time, the government of independent India renewed its focus on indigenous missile technology development. Initially, the scientists worked from MetCalfe House (New Delhi), but the establishment later shifted to Hyderabad after the state government granted them the former Nizam's army barracks. This was the genesis of the Defence Research and Development Laboratory (DRDL) – earlier known as the Special Weapons Development Team – under DRDO, solely formed for missile technology research and development.

Its first anti-tank missile was a totally indigenous product, which was successfully test-fired. The project laid the foundation of India's missile programme and many from this group who were involved in the development of the anti-tank missile to be used in Sarath ICVs manufactured at Ordnance Factory Medak, went on to set up the Bharat Dynamics Limited (BDL), Hyderabad in the proximity of the ordnance factory, which became the production agency of missiles in India. (In the 1970s, SS-11B anti-tank missiles were manufactured under license from France at the BDL.)

As Indian science and technology was curtailed before it became independent, and missile technology had developed at a fast pace after the second world war, India decided to update itself on missile technology by reverse engineering a surface-to-air missile. This project was code-named Project Devil and it worked, from 1970 to 1979, on reverse engineering the Russian SAM-2 (which Russia supplied to India). Dr. B. D. Nag Chaudhri (then Scientific Adviser to the Defence Minister) advocated the need to build technologies needed for the future, such as liquid propellant powered engines. Thus, a parallel program called Project Valiant was also initiated to build a rocket engine powered by liquid propellants. V. K. Saraswat was part of the team that built the engine between 1971 – 1974.

Other scientists at DRDO simultaneously focused on building a guidance package – an essential part of a long-range missile that determines its path and accuracy to hit a target. A platform-based inertial navigation system (INS) was developed and tested, on board an Avro aircraft, in 1974–75. Subsequently, an INS was built for both missiles and an aircraft, and this was tested in 1979 on board a Canberra aircraft.

By the start of 1980's, DRDL had developed competencies in the fields of propulsion, navigation and manufacture of materials. Thus, India's political and scientific leadership, which included prime minister Indira Gandhi, Defence Minister R. Venkataraman, V.S. Arunachalam (Scientific Advisor to the Defence Minister), decided that all these technologies should be consolidated.

This led to the birth of the Integrated Guided Missile Development Programme and Dr. Abdul Kalam, who had previously been the project director for the SLV-3 programme at ISRO, was inducted as the DRDL Director in 1983 to conceive and lead it. He decided that DRDL would pursue multiple projects in this area simultaneously. Thus, four projects were born under the IGMDP:


 * Short range surface-to-surface missile (code-named Prithvi)
 * Short range low-level surface-to-air missile (code-named Trishul)
 * Medium range surface-to-air missile (code-named Akash) and
 * Third-generation anti-tank missile (code-named Nag).

The Agni missile was initially conceived in the IGMDP as a technology demonstrator project in the form of a re-entry vehicle, and was later upgraded to a ballistic missile with different ranges. As part of this program, the Interim Test Range at Balasore in Orissa was also developed for missile testing.

Diplomatic and Technological Hurdles
After India test-fired the first Prithvi missile in 1988, and the Agni missile in 1989, the Missile Technology Control Regime (then an informal grouping established in 1987 by Canada, France, Germany, Italy, Japan, the United Kingdom and the United States) decided to restrict access to any technology that would help India in its missile development program. Some of the major technology which was denied, included:


 * phase shifters for the phased array radars for Akash (denied by the USA).
 * magnesium alloy used in Prithvi's wings (denied by Germany).
 * servo-valves needed for the electro-hydraulic control systems of Agni and Prithvi.
 * gyroscopes and accelerators (denied by France).
 * processors – Intel said it would not give India chips for the computers used in Prithvi and Agni.

To counter the MTCR, the IGMDP team formed a consortium of DRDO laboratories, industries and academic institutions to build these sub-systems, components and materials. Though this slowed down the progress of the program, India successfully developed indigenously all the restricted components denied to it by the MTCR.

In 2011, the DRDO Chief V K Saraswat had stated that "indigenous content" in India's strategic missiles had gone up to such a level, with ring-laser gyros, composite rocket motors, micro-navigation systems etc., that "no technology control regime" could derail them any longer.

Project Devil
Project Devil was one of two early liquid-fuelled missile projects developed by India, along with Project Valiant, in the 1970s. The goal of Project Devil was to produce a short-range surface-to-air missile. Although discontinued in 1980 without achieving intended success, Project Devil, led to the later development of the Prithvi missile in the 1980s.

Project Valiant
Project Valiant was one of two early liquid-fuelled missile projects developed by India, along with Project Devil in the 1970s. The goal of Project Valiant was to produce an ICBM. Although discontinued in 1974 without achieving full success, Project Valiant, like Project Devil, helped in the development of the Prithvi missile in the 1980s.

IGMDP
The Integrated Guided Missile Development Program (IGMDP) was a Ministry of Defence (India) program for the research and development of a comprehensive range of missiles. The program was managed by the Defense Research and Development Organization (DRDO) and Ordnance Factories Board in partnership with other Indian government research organisations. The project started in early 1980s and ended in 2008 after these strategic missiles were successfully developed. The last major missile developed under the program was the Agni 3 intermediate-range ballistic missile which was successfully tested on 9 July 2007.

On 8 January 2008, the DRDO formally announced the successful completion of the IGMDP. It added that the strategic integrated guided missile program was completed with its design objectives achieved since most of the missiles in the program had been developed and inducted by the Indian armed forces.

Dr. Abdul Kalam, who conceived and worked on this program, later also became the President of India.

Aakash
Aakash (Sanskrit: आकाश Ākāś "Sky") is a medium-range mobile surface-to-air missile defence system developed by the Defence Research and Development Organisation (DRDO), Ordnance Factories Board and Bharat Electronics Limited (BEL) in India. The missile system can target aircraft up to 30 km away, at altitudes up to 18,000 m.

Nag
Nag (Sanskrit: नाग, Nāg "Cobra") is a third generation "Fire-and-forget" anti-tank missile developed in India. It is one of five missile systems developed by the Defence Research and Development Organisation (DRDO) under the Integrated Guided Missile Development Program (IGMDP). Nag has been developed at a cost of inr 3000000000.

Prithvi Missile Series
Prithvi Missiles are tactical surface-to-surface short-range ballistic missiles (SRBM)

Dhanush is a system consisting of a stabilization platform (Bow) and the Missile (Arrow). It is intended for the Indian Navy, to be fired from ships against other ships or land targets. Dhanush can fire modified versions of Prithvi-II or Prithvi-III.

Agni missile series
The Agni missile series started as a "Re-Entry Vehicle" project (later rechristened as Agni Technology Demonstrator) in the IGMDP. The missiles in this series include:

The Agni-I, Agni-II and Agni-III missiles were developed under the IGMDP. (The DRDO formally announced the successful completion of the IGMDP after the third test of Agni-III on 7 May 2008. )

Agni-IV was tested on 15 November 2011 and has a range of 3000 km, and can carry a warhead of 1 tonnes. It is a two-stage missile powered by solid propellant. It is 20 m tall and has a launch weight of 17 tonnes. A new missile Agni-V with 5000 km range and MIRV is being developed and was tested on 19 April 2012. Agni-V shares the similar design as Agni-III with an extra stage added to further increase the range by 1500 km. Agni-V will be road mobile and it has been stated that all Indian missiles developed after this will be road mobile as well.

Agni-VI is an Intercontinental ballistic missile reported to be in rudimentary stages of development by India, and until May 2012 was not officially confirmed by either the Government of India or the DRDO. Reportedly, it will be capable of being launched from submarines or from land and to strike a target of over 10000 km with MIRV-ed warheads. Top DRDO scientists have previously asserted that India has almost all the equipment and technology needed to develop ICBMs, "but where the warhead should go or what the range should be will have to be a political call".

Shaurya
The Shaurya missile is a short-range surface-to-surface ballistic missile developed for use by the Indian Army. Capable of hypersonic speeds, it has a range of 600 km and is capable of carrying a payload of one-tonne conventional or nuclear warhead.

Hypersonic Technology Demonstrator Vehicle (HSDTV)
Project HSTDV is a technology demonstrator aimed to demonstrate autonomous flight of a Scramjet Integrated Vehicle using kerosene.

Prithvi Air Defence (PAD)


The Prithvi Air Defense missile has been named as Pradyumna Ballistic Missile Interceptor. It has a maximum interception altitude of 80 km and is capable of engaging the 300 to 2,000 km class of ballistic missiles at a speed of Mach 5. DRDO is currently working on a missile for intercepting targets of 5,000+ km range and engaging them at altitudes of up to 150 km.The tests are expected to commence from 2010–11.

Advanced Air Defence (AAD)

Also known as Ashwin Ballistic Missile Interceptor.

Anti-Radiation Missile
India is developing an Anti-Radiation Missile (ARM) that will help to destroy enemy advance warning systems. Production of the ARM is being done on a priority basis by the Defence Research and Development Laboratory (DRDL), which specialises in missile development. Such missiles can be mounted on the Sukhoi Su-30 MKI fighter planes.

Anti-Satellite Missile
India is developing anti satellite weapons. Following the successful Agni-V ICBM test, this looks all the more achievable. In an interview with India Today Dr. V. K. Saraswat said, "Today, India has all the building blocks for an anti-satellite system in place.

We don't want to weaponise space but the building blocks should be in place. Because you may come to a time when you may need it. Today, I can say that all the building blocks (for an ASAT weapon) are in place. A little fine tuning may be required but we will do that electronically. We will not do a physical test (actual destruction of a satellite) because of the risk of space debris affecting other satellites."

According to Rajeswari Rajagopalan, senior fellow at Observer Research Foundation, New Delhi, "it is important to discuss various issues concerning space security, and ASAT is one of them." Increasing awareness of space debris and continued efforts to develop and implement international measures to tackle the problem is a major concern for India as well as other countries.

According to some researchers, "as it stands today, in space, the probability of debris hitting a satellite is more than an adversary taking your satellite down."

Research and Development Organizations
Current missile research and development in India happens under the Defence Research and Development Laboratory (DRDL), and a group of laboratories collectively called the Missile Complex Laboratories.

Defence Research and Development Laboratory (DRDL)
Develops the mission control software among other missile technologies.

Other Developments
There were a number of failures and successes, which led to an expansion of the program in the 1990s, to develop the long range Agni missile, a ballistic missile (codenamed Sagarika), which would be the naval version of the Prithvi, and an inter-continental-ballistic-missile (codenamed Surya missile) with a range of 8,000–12,000 km.

In 1998, the Government of India, signed an agreement with Russia to design, develop, manufacture and market a Supersonic Cruise Missile System which has been successfully accomplished by 2006. BrahMos is a supersonic cruise missile that can be launched from submarines, ships, aircraft or land. At speeds of Mach 2.5 to 2.8, it is the world's fastest cruise missile and is about three and a half times faster than the American subsonic Harpoon cruise missile. BAPL is contemplating a hypersonic Mach 8 version of the missile, named as the BrahMos II. BrahMos II will be the first hypersonic cruise missile and is expected to be ready by 2012–13. The laboratory testing of the missile has started.

According to a statement by Dr. S Prahlada (DRDO Director), new missile and weapons systems would henceforth be developed in five-year programs and include both Indian private industries as well as foreign partners to lower costs. Further development work on Nag and Surya missile would continue independently. In addition, the DRDO is also developing a laser-based weapon system as part of its ballistic missile defence program to intercept and destroy missiles soon after they are launched towards the country.

Since 2008, follow on strategic projects are being either pursued singly (e.g. the Agni project) whereas tactical systems could involve joint ventures with foreign partners.

India is said to be in the intermediate stages of developing a new cruise missile, Nirbhay (Sanskrit: निर्भय meaning fearless). The subsonic Nirbhay is said to be 6 m in length with a 520 mm diameter, weigh 1,000 kg and have a 1,000 km range with a speed of 0.7 mach. The technology demonstrator flight is planned for end-2009.

In September 2008, Indian scientists developed a path-breaking technology that has the potential to increase the range of missiles and satellite launch vehicles by at least 40%.The enhanced range is made possible by adding a special-purpose coating of chromium metal to the blunt nose cone of missiles and launch vehicles. This would add-up on the stated range.

A new tactical missile that will fill the gap between the Pinaka rocket system and the Prthvi series of missile has been developed. The first successful test of the missile was carried on 17 July 2011. The 150 km range missile has been named Prahaar. Each Road mobile launcher is designed to carry six missiles.
