== Chemical weapons ==
India's first Nuclear test occurred on ] ]. Since then India has conducted another series of test at the ] test range in the state of ] in 1998. India has an extensive civil and military nuclear program, which includes at least 10 ]s, ] mining and milling sites, ] production facilities, a uranium enrichment plant, fuel fabrication facilities, and extensive nuclear research capabilities.

In 1992, India signed the ] (CWC), becoming one of the original signatories of the CWC in 1993,<ref>{{cite web|title=Member State – India|url=https://www.opcw.org/about-opcw/member-states/member-states-by-region/asia/member-state-india/|website=OPCW|access-date=5 September 2017|archive-url=https://web.archive.org/web/20171026045513/https://www.opcw.org/about-opcw/member-states/member-states-by-region/asia/member-state-india/|archive-date=26 October 2017|url-status=dead}}</ref> and ratified it on 2 September 1996. According to India's ex-Army Chief ], a country having the capability of making nuclear weapons does not need to have chemical weapons, since the dread of chemical weapons could be created only in those countries that do not have nuclear weapons. Others suggested that the fact that India has found chemical weapons dispensable highlighted its confidence in the conventional weapons system at its command.

As a result, Shastri announced that India would pursue the capability of what it called "]s" that could be weaponized in the future.<ref name=":1" />
=== Doctrine ===
]
India has a declared nuclear no-first-use policy and is in the process of developing a nuclear doctrine based on "credible minimum deterrence." In August 1999, the Indian government released a draft of the doctrine which asserts that nuclear weapons are solely for deterrence and that India will pursue a policy of "retaliation only." The document also maintains that India "will not be the first to initiate a nuclear first strike, but will respond with punitive retaliation should deterrence fail" and that decisions to authorize the use of nuclear weapons would be made by the Prime Minister or his 'designated successor(s).'"


India first tested a nuclear device in 1974 (code-named "]"), under Prime Minister ] as a peaceful nuclear explosion. The test used plutonium produced in the Canadian-supplied ], and raised concerns that nuclear technology supplied for peaceful purposes could be diverted to weapons purposes. This also stimulated the early work of the ].<ref> Nuclear Threat Initiative. 2006. {{webarchive|url=https://web.archive.org/web/20081001012955/http://www.nti.org/e_research/profiles/india/nuclear/2296_6267.html|date=1 October 2008}}</ref> During the 1970s and the 1980s Prime Ministers Indira Gandhi, ], and ] opposed weaponizing its nuclear program beyond PNE and theoretical research. In 1982, Indira Gandhi refused to allow the ] to develop active nuclear weapons but also approved the ] that would develop missiles to deliver a nuclear warhead if India developed one. India also supported international ] and ] efforts.<ref name=":1"/>
According to the NRDC, despite the escalation of tensions between India and Pakistan in 2001-2002, India remains committed to its nuclear no-first-use policy. But an Indian foreign ministry official told Defense News in 2000 that a "'no-first-use' policy does not mean India will not have a first-strike capability."


The situation changed again in the late 1980s after the 1987 ] and the beginning of the ]. In 1989, Prime Minister Rajiv Gandhi gave Defense Secretary ] approval to develop the bomb. Chandra continued the program through successive governments in the 1990s after Gandhi lost power in the ]. India most likely completed weaponized nuclear warheads around 1994.<ref name=":1"/> India performed further nuclear tests in 1998 (code-named "]") under Prime Minister ]. In 1998, as a response to the continuing tests, the United States and Japan imposed sanctions on India, which have since been lifted.<ref>{{cite web |last=Wagner |first=Alex |date=2001 |title=Bush Waives Nuclear-Related Sanctions on India, Pakistan |url=https://www.armscontrol.org/act/2001_10/sanctionsoct01 |publisher=Arms Control Association}}</ref>
===Command and Control===
India's ] was formally established in 2003, with an Air Force officer, Air Marshall ], as the Commander-in-Chief. The joint services SNC is the custodian of all of India's nuclear weapons, ] and assets. It is also responsible for executing all aspects of India's nuclear policy. However, the civil leadership, in the form of the CCS (Cabinet Committee on Security) is the only body authorized to order a nuclear strike against another offending strike: In effect, it is the ] who has his finger "on the button".

===Delivery Systems=== ===Indian nuclear triad===
{{See also|Nuclear triad}}
====Ballistic Missiles====
India's nuclear triad is a military force structure that includes three parts:


* Intercontinental ballistic missiles (ICBMs): Land-based nuclear missiles
India is only the fourth country that has ] capability called in India as the ] or the ]. The ] (IGMDP) was an Indian Ministry of Defence program for the development of a comprehensive range of missiles, including the intermediate range Agni missile (Surface to Surface), and short range missiles such as the Prithvi ballistic missile (Surface to Surface), Akash missile (Surface to Air), Trishul missile (Surface to Air) and Nag Missile (Anti Tank). The program was headed by Defense Research and Development Organization (DRDO), with former President of India, Dr. Abdul Kalam, being one of the chief engineers involved in the project.
* Submarine-launched ballistic missiles (SLBMs): Nuclear-missile-armed submarines
* Strategic bombers: Aircraft with nuclear bombs and missiles


The purpose of India's nuclear triad is to increase nuclear deterrence by reducing the chance of an enemy destroying all of India's nuclear forces in a first-strike attack. This ensures that India can still launch a second strike.<ref>{{cite web|url=https://www.orfonline.org/expert-speak/indias-nuclear-triad-still-a-work-in-progress|title=India’s nuclear triad: still a work in progress}}</ref>
India has methodically built an indigenous missile production capability, using its commercial space-launch program to develop the skills and infrastructure needed to support an offensive ballistic missile program. For example, during the 1980s, India conducted a series of space launches using the solid-fueled SLV-3 booster. Most of these launches put light satellites into near-earth orbit. Elements of the SLV-3 were subsequently incorporated into two new programs. In the first, the new polar-space launch vehicle (]) was equipped with six SLV-3 motors strapped to the PSLV's first stage. The Agni IRBM technology demonstrator uses the SLV-3 booster as its first stage.


Here are some details about India's nuclear triad:
The key missile applications and types are given below:

The Prithvi I is mobile liquid-fueled 150 kilometer tactical missile currently deployed with army units. It is claimed that this missile is equipped only with various conventional warheads (which stay attached to the missile over the entire flight path). The missile is of particular interest to the United States (and potential buyers) in that has the capability of maneuvering in flight so as to follow one of several different preprogrammed trajectories. Based on the same design, a modified Prithvi, the Prithvi II, is essentially a longer-ranged version of the Prithvi I except that it has a 250-kilometer range and a lighter payload. It is suspected that any nuclear missions will be executed by the Prithvi II. Currently, the Prithvi II has completed development and is now in production. When fielded, it will be deployed with air force units for the purpose of deep target attacking manoeuvres against objectives such as air fields. For the ], a 350-kilometer version of the Prithvi is under development. The new system is being called the ], testing is planned to begin in December 1998. It is unclear whether or not this system will be deployed on India's new nuclear missile submarine (under construction).


====Air-launched nuclear weapons====
The Prithvi missile project encompassed developing 3 variants for use by the Indian Army, Indian Air Force and the Indian Navy. The initial project framework of the Integrated Guided Missile Development Program outlines the variants in the following manner.

The 1500-kilometer Agni I technology demonstrator uses the SLV-3 booster for its first stage and a liquid-fueled Prithvi for its second stage. Three test shots were conducted before the U.S. successfully pressured India into suspending testing (1994). Of particular interest, the Agni tests demonstrated that India can develop a maneuvering warhead that incorporates endo-atmospheric evasive maneuvers and terminal guidance in the reentry vehicle. India has also developed the carbon-carbon composite materials needed for long-range missile components and reentry vehicle ablative coatings. India has also inducted Agni II misiles that have a range of the 2500 to 3500-kilometers. Unlike the Agni I, the Agni II will have a solid-fueled second stage. It is believed that the Agni can only be equipped with a conventional warhead. India recently tested the Agni III IRBM with a range between 5000 and 18000 kilometers <ref></ref> which has two stages. Though this range only depends on the load. With a load of 1800Kg the Agni can travel 5000km but with 400kg load it can travel 18000.{{Fact|date=July 2007}} With a usual 1000kg it can travel 8000km. It is clear that one of the major constraints for this program is the lack of a proven nuclear warhead. Nuclear testing is a key related issue. India developed its own thermonuclear design which was tested in the 1998 Pokhran nuclear tests and yielded 45 KT. DRDO is working on a Submarine Launched Version of the Agni-III missile, which will provide India with a credible sea based second strike capability.<ref></ref> The SLBM version is a miniaturized version of the Agni-III which is expected to be test fired shortly.<ref></ref>

The ] is an ] program that has been discussed repeatedly in the Indian press. Surya (meaning The Sun in Sanskrit and Many Indian Languages) is the codename for the first Intercontinental Ballistic Missile that India is reported to be developing. The DRDO is believed to have begun the project in 1994. Officials of the Indian government have repeatedly denied the existence of the project. According to news reports, the Surya-1 is an intercontinental-range, surface-based, solid and liquid propellant ballistic missile. The Surya-1 and -2 will be classified as strategic weapons, extending the Indian nuclear deterrent force to targets around the world. India currently is limited by the range of the Agni-3 missile. The development of a true ICBM would make strikes against almost any strategic target around the world possible and reduce India’s relative weakness. This would develop a credible global deterrent for India. The Surya-1 will have an expected range of 10,000 km. It reportedly has a length of 40 m and a launch weight of 80,000 kg (some reports indicate as much as 275,000 kg. As the missile has yet to be developed, the payload and warhead are as yet unknown. It is believed to be a three-stage design, with the first two stages using solid propellants and the third-stage using liquid. The Surya-2 is a longer-ranged variant of the Surya-1. It has a reported range of 20,000 km. The first test flight is expected in 2008, and it is expected to be operationally ready by 2015.

====Cruise Missiles====

]
BrahMos is a supersonic cruise missile that can be launched from submarines, ships, aircraft or land. The acronym BrahMos is perceived as the confluence of the two nations represented by two great rivers, the Brahmaputra of India and the Moskva of Russia. It is a joint venture between India's Defense Research and Development Organization and Russia's NPO Mashinostroeyenia who have together formed the BrahMos Corp. Propulsion is based on the Russian Yakhont missile, and guidance has been developed by BrahMos Corp. At speeds of Mach 2.5 to 2.8, is the world's fastest cruise missile. At about three and a half times faster than the American subsonic Harpoon cruise missile


In an interview in August 2009, the director for the 1998 test site preparations, K.

====Air to Air Missiles====
* ''']'''
Astra(Sanskrit: अस्त्रा, Astrā "Weapon") is an active radar homing Beyond visual range air to air missile (BVRAAM) or a ] being developed by Defence Research and Development Organisation (DRDO), India. This is the first air-to-air nuclear capable missile developed by India. Most other air-to-air missiles of India are bought from Russia.


However, India officially maintains that it can build thermonuclear weapons of various yields up to around {{convert|200|ktonTNT|abbr=on}} based on the ] thermonuclear test.<ref name=":6" /><ref>{{Cite journal |date=25 September 2009 |title=Nukes of 200kt yield possible: Architect of Pokhran-II |url=https://timesofindia.indiatimes.com/india/Nukes-of-200kt-yield-possible-Architect-of-Pokhran-II/articleshow/5053406.cms |journal=The Times of India}}</ref>
The range of Astra is 80 km in head-on chase and 15 km in tail chase. The missile's onboard radio-frequency seeker has been designed in India. It will have an active homing range of 15 km. The missile has a pre-fragmented warhead and is fitted with a proximity fuze. A radar fuze already exists for the Astra, but the DRDO is currently working on a new laser fuze.The first test to happen with a nuclear warhead on board the missile is to take place in 2008.A successful test flight of ASTRA will plunge India into a select group of nations to have such a technology. Only US, France, Russia and China have so far produced such advance missiles, which enables fighter pilots to lock-on and shoot down enemy aircraft almost 90-120 km away.<ref></ref>

According to some accounts India plans to have as many as five nuclear submarines capable of carrying missiles with nuclear warheads. Currently, India is building 3 nuclear submarines under the Advanced Technology Vessel plan. The Indian nuclear powered attack submarine design is said to have a 6,000-ton displacement and a single-shaft nuclear power plant of Indian origin.<ref></ref> Once the vessel is completed, it may be equipped with nuclear capable ] or ] missiles and an advanced sonar system. However, according to some analysts the most probable missile for the Indian submarine would be the nuclear capable ] anti-ship cruise missile designed jointly by India and Russia, based on the ] missile by NPO Mashinostroyeniya.

India has an advanced commercial chemical industry, and produces the bulk of its own chemicals for domestic consumption.

India became one of the original signatories of the Chemical Weapons Convention in 1993, and ratified it on ] ]. Since, unlike the nuclear non- proliferation treaty and the comprehensive test ban treaty, this treaty's provisions were equally applicable to all countries, including the powerful countries, India had readily accepted it.

As India has one of the largest chemical industries in the world, this industry will benefit from unrestricted trade and technology access which would be denied to non-members of the treaty.
* features a number of compilations of declassified US government documents related to India's nuclear program.
Although India had endorsed the treaty in September 1996, becoming the 62nd country to do so, when it appeared as though the United States might not approve it, India too declared that it might review its earlier decision endorsing the treaty. Indian observers were of the view that, should America itself fail to approve the treaty, there would be diminished pressure on China and Pakistan against producing chemical weapons. According to India's ex-Army Chief General Sunderji, a country having the capability of making nuclear weapons does not need to have chemical weapons, since the dread of chemical weapons could be created only in those countries that do not have nuclear weapons. Others suggested that the fact that India has found chemical weapons dispensable highlighted its confidence in the conventional weapons system at its command.

When the Third UN Disarmament Conference, held in 1988, decided that the next logical step in the disarmament process would be measures to halt production of chemical weapons, Indian diplomats responded by claiming that India had no chemical weapons. Foreign Minister K Natwar Singh repeated this claim in 1989 in the Paris Conference of the State Parties to the Geneva Protocol of 1925, as did Minister of State Eduardo Faleiro repeated at the January 1993 Paris Conference CWC signing ceremony. However, India declared its stockpile of chemical weapons to the Chemical Weapons Convention in Geneva on ] ], the deadline for all signatories to the pact. New Delhi publicly declared that, in keeping with the stipulations arising from the ratification of the Chemical Weapons Convention, India had filed initial declarations on "testing and development of chemical weapons and their related facilities which were developed only to deal with the situation arising out of possible use of chemical warfare against India."

In its required declarations under the CWC, India acknowledged the existence of a chemical warfare program. and disclosed the details of its stockpiles and the availability of manufacturing facilities on a very small scale. New Delhi has pledged that all facilities related to its CW program would be open for inspection. The declaration kept India's chemical armory under wraps, since the CWC Secretariat maintains the confidentiality of the declaration. <sup>]</sup>

The published literature detailing India's chemical weapons capabilities is extremely sparse. According to one published report, India's stockpile of chemical weapons consists of mustard gas shells left by the British of World War II vintage. These shells, fired from a 25 pounder gun, are said to be in storage and not under the operational control of the Indian Army. India is also reported to have manufacturing facilities for production of agents in small quantities.

The Indian government has set up Nuclear, Biological and Chemical (NBC) warfare directorates in the Services, besides an inter-Services coordination committee to monitor the programme. The Indian Army established a Nuclear, Biological and Chemical (NBC) cell at Army HQ to study the effects of NBC warfare. The Defence Research and Development Organisation (DRDO) is also participating in the program. Research on chemical weapons has continued in various establishments of the military and DRDO research labs. In addition, work is carried out by DRDO to design and fabricate protective clothing and equipment for troops on the battlefield in case of a chemical weapons attack. The Defence Research and Development Establishment (DRDE) at Gwalior is the primary establishment for studies in toxicology and biochemical pharmacology and development of antibodies against several bacterial and viral agents. In addition, research is carried out on antibodies against chemical agent poisoning and heavy metal toxicology. Chemical agents such as Sarin and nerve gas are produced in small quantities to test on protective equipment.

Protective clothing and equipment are designed and manufactured amongst other places at the Defence Materials and Stores Research and Development Establishment at Kanpur. India has developed five types of protective systems and equipment for its troops as a safeguard against nuclear, biological and chemical (NBC) hazards. The development of all five types of protective systems and equipment has been completed and their induction into the service has been formally approved. The five types of protective systems and equipment are: NBC individual protective equipment, NBC collective protection system, NBC medical protection equipment, NBC detection equipment and the NBC decontamination system.

It is reported that even after India ratified the Chemical Weapons Treaty in September 1996, efforts continued for manufacturing and stockpiling chemical weapons for use against Pakistan. India's Prithvi surface-to-surface missiles (SSMs) can carry five different types of warheads. Two types of warheads have already been deployed, and three other warheads, presumably nuclear, chemical and biological, are under development. On ] ], the Indian government stated that "India will disclose to Pakistan stocks of its chemical weapons". The decision was taken to make a unilateral disclosure on the instruction of Prime Minister I.K. Gujral.

India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 172 nuclear weapons and has produced enough weapons-grade plutonium for up to 200 nuclear weapons. In 1999, India was estimated to have 800 kilograms (1,800 lb) of separated reactor-grade plutonium, with a total amount of 8,300 kilograms (18,300 lb) of civilian plutonium, enough for approximately 1,000 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely Pokhran I and Pokhran II.

India is a member of three multilateral export control regimes — the Missile Technology Control Regime, Wassenaar Arrangement and Australia Group. It has signed and ratified the Biological Weapons Convention and the Chemical Weapons Convention. India is also a subscribing state to the Hague Code of Conduct. India has signed neither the Comprehensive Nuclear-Test-Ban Treaty nor the Nuclear Non-Proliferation Treaty, considering both to be flawed and discriminatory. India previously possessed chemical weapons, but voluntarily destroyed its entire stockpile in 2009 — one of the seven countries to meet the OPCW extended deadline.

India maintains a "no first use" nuclear policy and has developed a nuclear triad capability as a part of its "Minimum Credible Deterrence" doctrine.

Biological weapons

Further information: History of biological warfare

India has ratified the Biological Weapons Convention (BWC) and pledges to abide by its obligations. There is no clear evidence, circumstantial or otherwise, that directly points toward an offensive BW program. India does possess the scientific capability and infrastructure to launch an offensive BW program. In terms of delivery, India also possesses the capability to produce aerosols and has numerous potential delivery systems ranging from crop dusters to sophisticated ballistic missiles. No information exists in the public domain suggesting interest by the Indian government in the delivery of biological agents by these or any other means. To reiterate the latter point, in October 2002, then-President A. P. J. Abdul Kalam asserted that "India will not make biological weapons. It is cruel to human beings".

Chemical weapons

Further information: Chemical weapon

In 1992, India signed the Chemical Weapons Convention (CWC), becoming one of the original signatories of the CWC in 1993, and ratified it on 2 September 1996. According to India's ex-Army Chief General Sundarji, a country having the capability of making nuclear weapons does not need to have chemical weapons, since the dread of chemical weapons could be created only in those countries that do not have nuclear weapons. Others suggested that the fact that India has found chemical weapons dispensable highlighted its confidence in the conventional weapons system at its command.

In June 1997, India declared its stock of chemical weapons (1,045 tonnes of sulphur mustard). By the end of 2006, India had destroyed more than 75 percent of its chemical weapons/material stockpile and was granted an extension for destroying the remaining stocks by April 2009 and was expected to achieve 100 percent destruction within that time frame. India informed the United Nations in May 2009 that it had destroyed its stockpile of chemical weapons in compliance with the international Chemical Weapons Convention. With this India has become the third country after South Korea and Albania to do so. This was cross-checked by inspectors of the United Nations.

India has an advanced commercial chemical industry, and produces the bulk of its chemicals for domestic consumption. It is also widely acknowledged that India has an extensive civilian chemical and pharmaceutical industry and annually exports considerable quantities of chemicals to countries such as the United Kingdom, the United States, and Taiwan.

Nuclear weapons

See also: India–United States Civil Nuclear Agreement Further information: Strategic Forces Command

As early as 26 June 1946, Jawaharlal Nehru, soon to be India's first Prime Minister, announced:

As long as the world is constituted as it is, every country will have to devise and use the latest devices for its protection. I have no doubt India will develop her scientific researches and I hope Indian scientists will use the atomic force for constructive purposes. But if India is threatened, she will inevitably try to defend herself by all means at her disposal.

Nehru pursued a policy of formally foregoing nuclear weapons while at the same time constructing a civilian nuclear energy program and by extension the capability to make a nuclear bomb. This policy was motivated by a conventional weapons superiority over its rivals Pakistan and China. India built its first research reactor in 1956 and its first plutonium reprocessing plant by 1964. India's nuclear programme can trace its origins to March 1944 and its three-stage efforts in technology were established by Homi Jehangir Bhabha when he founded the nuclear research center, the Tata Institute of Fundamental Research.

India's loss to China in a brief Himalayan border war in October 1962, provided the New Delhi government impetus for developing nuclear weapons as a means of deterring potential Chinese aggression. By 1964 India was in a position to develop nuclear weapons. Prime Minister Lal Bahadur Shastri opposed developing nuclear weapons but fell under intense political pressure, including elements within the ruling Indian National Congress. India was also unable to obtain security guarantees from either the United States or the Soviet Union. As a result, Shastri announced that India would pursue the capability of what it called "peaceful nuclear explosions" that could be weaponized in the future.

India first tested a nuclear device in 1974 (code-named "Smiling Buddha"), under Prime Minister Indira Gandhi as a peaceful nuclear explosion. The test used plutonium produced in the Canadian-supplied CIRUS reactor, and raised concerns that nuclear technology supplied for peaceful purposes could be diverted to weapons purposes. This also stimulated the early work of the Nuclear Suppliers Group. During the 1970s and the 1980s Prime Ministers Indira Gandhi, Morarji Desai, and Rajiv Gandhi opposed weaponizing its nuclear program beyond PNE and theoretical research. In 1982, Indira Gandhi refused to allow the Defence Research and Development Organisation to develop active nuclear weapons but also approved the Integrated Guided Missile Development Programme that would develop missiles to deliver a nuclear warhead if India developed one. India also supported international nuclear non-proliferation and arms control efforts.

The situation changed again in the late 1980s after the 1987 Brasstacks crisis and the beginning of the Pakistani nuclear weapons program. In 1989, Prime Minister Rajiv Gandhi gave Defense Secretary Naresh Chandra approval to develop the bomb. Chandra continued the program through successive governments in the 1990s after Gandhi lost power in the 1989 general election. India most likely completed weaponized nuclear warheads around 1994. India performed further nuclear tests in 1998 (code-named "Operation Shakti") under Prime Minister Atal Bihari Vajpayee. In 1998, as a response to the continuing tests, the United States and Japan imposed sanctions on India, which have since been lifted.

Neutron bombs

R Chidambaram, who headed India's Pokhran-II nuclear tests, said in a 1999 interview with the Press Trust of India that India is capable of producing a neutron bomb.

India's no-first-use policy

India has a declared nuclear no-first-use policy and is in the process of developing a nuclear doctrine based on "credible minimum deterrence." In August 1999, the Indian government released a draft of the doctrine which asserts that nuclear weapons are solely for deterrence and that India will pursue a policy of "retaliation only". The document also maintains that India "will not be the first to initiate a nuclear first strike, but will respond with punitive retaliation should deterrence fail" and that decisions to authorize the use of nuclear weapons would be made by the Prime Minister or his 'designated successor(s)'. According to the NRDC, despite the escalation of tensions between India and Pakistan in 2001–2002, India remained committed to its nuclear no-first-use policy.

India's Strategic Nuclear Command was formally established in 2003, with an Indian Air Force officer, Air Marshal Tej Mohan Asthana, as the Commander-in-Chief. The Joint Services SNC is the custodian of all of India's nuclear weapons, missiles and defense assets. It is also responsible for executing all aspects of India's nuclear policy. However, the civil leadership, in the form of the CCS (Cabinet Committee on Security) is the only body authorised to order a nuclear strike against another offending strike. The National Security Advisor Shivshankar Menon reiterated a policy of "no first use" against nuclear weapon states and "non-use against non-nuclear weapon states" in a speech on the occasion of Golden Jubilee celebrations of National Defence College in New Delhi on 21 October 2010, a doctrine Menon said reflected India's "strategic culture, with its emphasis on minimal deterrence. In April 2013 Shyam Saran, convener of the National Security Advisory Board, affirmed that regardless of the size of a nuclear attack against India, be it a miniaturised version or a "big" missile, India will retaliate massively to inflict unacceptable damage.

In 2016, Defence Minister Manohar Parrikar questioned the no-first-use policy, asking why India should "bind" itself when it is a "responsible nuclear power". Later he clarified that this was his personal opinion. Defence Minister Rajnath Singh in 2019 said that in the future, India's no-first-use policy might change depending upon the "circumstances". In a January 2022 statement, however, the Ministry of External Affairs reiterated India's doctrine of "maintaining a credible minimum deterrence based on a No First Use posture and non-use of nuclear weapons against non-nuclear weapon states".

Indian nuclear triad

See also: Nuclear triad

India's nuclear triad is a military force structure that includes three parts:

  • Intercontinental ballistic missiles (ICBMs): Land-based nuclear missiles
  • Submarine-launched ballistic missiles (SLBMs): Nuclear-missile-armed submarines
  • Strategic bombers: Aircraft with nuclear bombs and missiles

The purpose of India's nuclear triad is to increase nuclear deterrence by reducing the chance of an enemy destroying all of India's nuclear forces in a first-strike attack. This ensures that India can still launch a second strike.

Here are some details about India's nuclear triad:

  • INS Arighaat: India's second nuclear submarine, INS Arighaat, has improved nuclear propulsion technology that allows it to operate more stealthily. It can carry up to four K-4 SLBMs or up to 12 K-15 SLBMs.
  • INS Arihant: India's first nuclear submarine, INS Arihant, was commissioned in 2016.
  • No-first-use policy: India's policy is to not use nuclear weapons against non-nuclear weapon states and to only use them in self-defense against nuclear weapon states.

Air-launched nuclear weapons

The Mirage 2000 of the Indian Air Force is believed to be assigned the nuclear strike role, operating from Maharajpur Air Force Station.

Nuclear-armed fighter-bombers were India's first and only nuclear-capable strike force until 2003 when the country's first land-based nuclear ballistic missiles were fielded.

In addition to their ground-attack role, it is believed that the Dassault Mirage 2000s and SEPECAT Jaguars of the Indian Air Force are able to provide a secondary nuclear-strike role. The SEPECAT Jaguar was designed to be able to carry and deploy nuclear weapons and the Indian Air Force has identified the jet as being capable of delivering Indian nuclear weapons. The most likely delivery method would be the use of bombs that are free-falling and unguided.

Three airbases with four squadrons of Mirage 2000H (about 16 aircraft with 16 bombs from 1st and 7th squadrons of the 40th Wing at Maharajpur Air Force Station) and Jaguar IS/IB (about 32 aircraft with 32 bombs from one squadron each at Ambala Air Force Station and Gorakhpur Air Force Station) aircraft are believed to be assigned the nuclear strike role.

Land-based ballistic missiles

Agni-V during its first test flight on 19 April 2012

The estimated 68 nuclear warheads of land-based nuclear weapons of India are under the control of and deployed by the Strategic Forces Command, using a variety of vehicles and launching silos. They currently consist of six different types of ballistic missiles, the Agni-I, the Agni-II, Agni-III, Agni-IV, Agni-V, Agni-P, and the Army's variant of the Prithvi missile family – the Prithvi-I. However, the Prithvi missiles are less useful for delivering nuclear weapons because they have a shorter range and must be deployed very close to the India–Pakistan border. Additional variants of the Agni missile series have recently been inducted including the most recent, the Agni-IV and the Agni-V, which is currently being deployed. Agni-VI is also under development, with an estimated range of 10,000–12,000 km and features such as Multiple independently targetable reentry vehicles (MIRVs) or Maneuverable reentry vehicles (MARVs).

Sea-based ballistic missiles

K-15 Sagarika SLBM

The Indian Navy has developed two sea-based delivery systems for nuclear weapons, completing Indian ambitions for a nuclear triad, which may have been deployed in 2015.

A conceptual drawing of INS Arihant

The first is a submarine-launched system consisting of at least four 6,000-tonne (nuclear-powered) ballistic missile submarines of the Arihant class. The first vessel, INS Arihant, was commissioned in August 2016. She is the first nuclear-powered submarine to be built by India. A CIA report claimed that Russia provided technological aid to the naval nuclear propulsion program. The submarines will be armed with up to 12 Sagarika (K-15) missiles armed with nuclear warheads. Sagarika is a submarine-launched ballistic missile with a range of 700 km. This missile has a length of 8.5 meters, weighs seven tonnes and can carry a pay load of up to 50 kg. Sagarika has already been test-fired from an underwater pontoon, but now DRDO is planning a full-fledged test of the missile from a submarine and for this purpose may use the services of the Russian Navy. India's DRDO is also working on a submarine-launched ballistic missile version of the Agni-III missile, known as the Agni-III SL. According to Indian defence sources, the Agni-III SL will have a range of 3,500 kilometres (2,200 mi). The new missile will complement the older and less capable Sagarika submarine-launched ballistic missiles. However, the Arihant class ballistic missile submarines will be only capable of carrying a maximum of four Agni-III SL.

The second is a ship-launched system based around the short-range ship-launched Dhanush ballistic missile (a variant of the Prithvi missile). It has a range of around 300 km. In the year 2000, the short-range missile was test-fired from INS Subhadra (a Sukanya class patrol craft). INS Subhadra was modified for the test and the missile was launched from the reinforced helicopter deck. The results were considered partially successful. In 2004, the missile was again tested from INS Subhadra and this time the results were reported successful. In December 2005 the missile was tested again, but this time from the destroyer INS Rajput. The test was a success with the missile hitting the land based target.

Thermonuclear weapons

Shakti-1 thermonuclear device

On 11 May 1998, India announced that it had detonated a thermonuclear bomb in its Operation Shakti tests ("Shakti-I", specifically, in Hindi the word 'Shakti' means power). Samar Mubarakmand, a Pakistani nuclear physicist, asserted that if Shakti-I had been a thermonuclear test, the device had failed to fire. However, Harold M. Agnew, former director of the Los Alamos National Laboratory, said that India's assertion of having detonated a staged thermonuclear bomb was very much believable. India says that their thermonuclear device was tested at a controlled yield of 45 kt (190 TJ) because of the proximity of the Khetolai village at about 5 kilometres (3.1 mi), to ensure that the houses in that village do not suffer significant damage. Another cited reason was that radioactivity released from yields significantly more than 45 Kilotons might not have been contained fully. After the Pokhran-II tests, Rajagopala Chidambaram, former chairman of the Atomic Energy Commission of India said that India has the capability to build thermonuclear bombs of any yield at will.

The yield of India's hydrogen bomb test remains highly debatable among the Indian science community and international scholars. The question of politicisation and disputes between Indian scientists further complicated the matter.

In an interview in August 2009, the director for the 1998 test site preparations, K. Santhanam claimed that the yield of the thermonuclear explosion was lower than expected and that India should therefore not rush into signing the CTBT. Other Indian scientists involved in the test have disputed K. Santhanam's claim, arguing that Santhanam's claims are unscientific. British seismologist Roger Clarke argued that the magnitudes suggested a combined yield of up to 60 kilotonnes of TNT (250 TJ), consistent with the Indian announced total yield of 56 kilotonnes of TNT (230 TJ). U.S. seismologist Jack Evernden has argued that for correct estimation of yields, one should 'account properly for geological and seismological differences between test sites.

However, India officially maintains that it can build thermonuclear weapons of various yields up to around 200 kt (840 TJ) based on the Shakti-1 thermonuclear test.

International response

India is not a signatory to either the NPT or the Comprehensive Nuclear-Test-Ban Treaty (CTBT) but did accede to the Partial Nuclear Test Ban Treaty in October 1963. Journalist, conspiracy theorist, and holocaust denier Gregory Douglas claims CIA officer Robert Crowley told him in an interview in 1993 that India's pursuit of the programme disturbed the United States and that the CIA assassinated Prime Minister Shastri and Homi Bhabha in 1966. India is a member of the International Atomic Energy Agency (IAEA), and four of its 17 nuclear reactors are subject to IAEA safeguards. India announced its lack of intention to accede to the NPT as late as 1997 by voting against the paragraph of a General Assembly Resolution which urged all non-signatories of the treaty to accede to it at the earliest possible date. India voted against the UN General Assembly resolution endorsing the CTBT, which was adopted on 10 September 1996. India objected to the lack of provision for universal nuclear disarmament "within a time-bound framework." India also demanded that the treaty ban laboratory simulations. In addition, India opposed the provision in Article XIV of the CTBT that requires India's ratification for the treaty to enter into force, which India argued was a violation of its sovereign right to choose whether it would sign the treaty. In early February 1997, Foreign Minister I. K. Gujral reiterated India's opposition to the treaty, saying that "India favors any step aimed at destroying nuclear weapons, but considers that the treaty in its current form is not comprehensive and bans only certain types of tests."

In August 2008, the International Atomic Energy Agency (IAEA) approved a safeguards agreement with India under which the former will gradually gain access to India's civilian nuclear reactors. In September 2008, the Nuclear Suppliers Group granted India a waiver to access civilian nuclear technology and fuel from other countries. The implementation of this waiver makes India the only known country with nuclear weapons which is not a party to the NPT but is still allowed to carry out nuclear commerce with the rest of the world.

Since the implementation of the NSG waiver, India has signed nuclear deals with several countries including France, United States, Mongolia, Namibia, Kazakhstan and Australia while the framework for similar deals with Canada and the United Kingdom are also being prepared.

Domestic legislation

India has several laws in whole or partial measure that deal with the regulation of weapons of mass destruction. They include the Weapons of Mass Destruction and their Delivery Systems (Prohibition of Unlawful Activities) Act of 2005. In April 2022 a bill was tabled to amend the 2005 act to include the financing of proliferation.
