The MIRV leap that fires up India’s nuclear deterrence
Note4Students
From UPSC perspective, the following things are important :
Prelims level: Agni 5, Mission Divyastra
Mains level: Read the attached story
Why in the news?
- The Agni-5 ballistic missile test dubbed the “Divyastra”, that was conducted by the Defence Research and Development Organisation (DRDO), is strategically consequential
Context:
- With a range of over 5,000 kilometers, the Agni-5 is the longest-range missile India has tested so far. But it is not simply its range but, equally, its potency that represents a watershed moment for India’s nuclear deterrent.
- The potency of India’s nuclear deterrent is enhanced because this variant is integrated with Multiple Independently Targetable Re-entry Vehicles (MIRVs).
What are MIRVs?
MIRVs- A MIRV is a ‘missile bus’ whose passengers are nuclear bombs and which facilitates a single booster to deliver them to different targets. It means MIRV can target multiple targets that can be hundreds of kilometers apart with a single missile.
Background:
- In 1970, the U.S. started to deploy the Minuteman III, the first MIRV-ed intercontinental ballistic missile (ICBM) with three warheads on each missile. In 1971, it deployed the Poseidon, the first MIRV-ed submarine-launched ballistic missile (SLBM) which had the capability of carrying up to 10 warheads on each missile
- The Soviet Union followed the U.S. and by the 1970s developed its own MIRV-ed ICBM and SLBM technology.
- China has developed and deployed MIRV technology with multiple warheads placed on its DF-5B ICBMs
- France and the United Kingdom are known to have MIRV-equipped missiles.
Why MIRV technology is so lethal?
Unlike conventional missiles that deploy a single warhead, MIRV-equipped missiles can release multiple warheads from the missile at varying speeds and trajectories.
A comparison with China-
- India’s Late Entry: While MIRV technology is not new globally, India’s development of MIRV-capable ballistic missiles marks its entry into a select group of nations possessing such capabilities, including the established nuclear powers like the United States, Russia, China, France, and the United Kingdom.
- Potential for Damage Limitation: MIRV-tipped missiles are crucial for striking multiple targets simultaneously and evading ballistic missile defenses. China’s advancements in ballistic missile defenses, such as the HQ-19 interceptors, pose a challenge, although their efficacy against India’s Agni series missiles, especially the Agni-5, still needs to be improved.
- Need for Further Testing: While integrating MIRV technology into the Agni-5 is a significant step, continued testing and refinement will be necessary to enhance the credibility and effectiveness of India’s nuclear ballistic missile arsenal. The Indian armed services are likely to seek multiple tests to ensure reliability and readiness.
The complications against the development of MIRV-capable ballistic missiles include:
- Nuclear Warhead Miniaturization: Achieving miniaturization of nuclear warheads is a demanding technical requirement for MIRV-capable missiles. Inadequate nuclear testing by India has compromised the extent to which warheads could be miniaturized for MIRV applications.
- Receptacle Weight Reduction: The receptacle that carries the warhead or re-entry vehicle must be of low weight or mass before release from the Post Boost Vehicle (PBV). This requirement adds complexity to the design and engineering of the missile system.
- Precision Configuration: Re-entry vehicles must be precisely configured to fit into the missile and separate from the PBV, which needs to be manoeuvrable. This necessitates meticulous design and testing to ensure proper functionality.
- Guidance and Accuracy: Guidance and accuracy are essential for MIRV-capable missiles, as re-entry vehicles must be spin-stabilized during atmospheric re-entry. Achieving the required level of precision adds another layer of complexity to the development process.
- Geographic Limitation: MIRV-based missiles can only strike multiple targets within their geographic footprint. This limitation requires careful consideration in strategic planning and deployment.
- Limited Nuclear Testing: India’s limited nuclear testing history has restricted the extent to which warheads could be miniaturized and MIRV technology could be developed. This lack of testing has posed challenges to Indian missile and nuclear engineers.
- Integration Challenges: Integrating warheads with missiles involves complex processes and requires coordination among various agencies, such as the Terminal Ballistics Research Laboratory (TBRL) and Advanced Systems Limited (ASL). Overcoming integration challenges adds to the difficulty of MIRV development.
- Decoys and Countermeasures: Uncertainty remains regarding whether the Agni-5 missile can carry decoys and chaff, especially during the boost and intermediate phases of flight. Integrating countermeasures adds additional technical challenges.
- Launch Platform: Agni-5 is expected to be launched from a road-mobile platform, which introduces logistical and operational considerations for deployment.
Future Scope for Indian Projects:
- Submarine Launched Ballistic Missile (SLBM) Testing: India is set to test a long-range SLBM, which will be launched from its nuclear ballistic missile submarines. This project aims to further enhance India’s nuclear deterrence capabilities by adding a sea-based component to its arsenal.
- Continued Development by DRDO and AEC: The Defence Research and Development Organisation (DRDO) and the Atomic Energy Commission (AEC) of India are expected to continue their collaboration in developing advanced missile and nuclear technologies. This collaboration underscores India’s commitment to strengthening its defense capabilities.
- Strategic Focus on China: The development of the Agni-5 with MIRV capability specifically addresses potential threats from China’s missile and missile defense programs. India’s strategic focus remains on maintaining a credible deterrent vis-à-vis China.
- Enhanced Nuclear Capabilities: The successful test of the Agni-5 MIRV missile marks a significant milestone in India’s quest to become a highly credible nuclear and missile power. It signifies India’s determination to bolster its nuclear capabilities to counter emerging threats effectively.
Conclusion:
India’s MIRV advancements, though challenging, augment nuclear deterrence against China. Continued testing and SLBM development signify India’s commitment to bolstering defense capabilities and ensuring regional stability.

- The Pralay missile project was sanctioned in 2015 and is a derivative of the Prahaar missile programme, which was first tested in 2011.
- Developed by the DRDO, the ‘Pralay’ ballistic missile is a canisterised tactical, surface-to-surface, and short-range ballistic missile (SRBM) for battlefield use.
- It can hit targets from a distance of 150 to 500 km and is extremely difficult to intercept by enemy interceptor missiles.
- Pralay is powered by a solid fuel rocket motor and is a high explosive preformed fragmentation warhead that weighs somewhere between 350 kg to 700 kg.
- It also accounts for its Penetration-Cum-Blast (PCB) and Runaway Denial Penetration Submunitions (RDPS).
Unique features of Pralay
- Precise targeting: The missile is designed to destroy enemy radar, communication installations, command centres and airfields.
- Quasi Ballistic Trajectory: It means the object takes a low curved path after being shot.
- Stealth features: Pralay has the ability to evade any anti-ballistic missile (ABM) interceptors by performing mid-air manoeuvres by using a manoeuvrable re-entry vehicle.
- Destruction capability: When a high-explosive warhead, like the one Pralay missile is equipped with, explodes, its pieces are thrown at a high speed which can inflict heavy damage.
What makes Pralay lethal?
- The Indian missile can be compared to China’s Dong Feng 12 and the Russian Iskander missile that has been used in the ongoing war with Ukraine.
- The US Army is in the process of increasing the range of a similar short-range ballistic missile called the Precision Strike Missile (PrSM).
- What makes Pralay deadly is that it is a quasi-ballistic weapon, which means that while it has a low trajectory and is largely ballistic, it can manoeuvre in flight.
- Unlike intercontinental ballistic missiles that exit the Earth’s atmosphere, short-range ballistic missiles stay within it.
What lies ahead?
- Pralay, along with the BrahMos supersonic cruise missile, will form the crux of India’s planned Rocket Force — a concept that was envisaged by former Chief of Defence Staff (CDS), the late General Bipin Rawat.
- Only conventional missiles would come under the planned Rocket Force as and when it’s ready, while nuclear weapons would continue to be under the ambit of the Strategic Forces Command.

A resolution to ban kinetic ASAT tests
Note4Students
From UPSC perspective, the following things are important :
Prelims level: ASAT, space debris and related facts
Mains level: Space weaponization why ASAT test band is important
Context
- There is growing momentum behind a global moratorium on destructive kinetic anti-satellite (ASAT) tests. A few days ago, the United Nations General Assembly (UNGA) passed a resolution calling for a ban on kinetic ASAT tests.
Click and get your FREE Copy of CURRENT AFFAIRS Micro Notes
What the resolution is all about?
- Sponsored by United states: The resolution was sponsored by the United States along with a number of other countries that have been concerned about the consequences of ASAT tests on the safety and sustainability of outer space.
- Majority voted in support: As many as 155 countries voted in support of the resolution, nine voted against it, and nine others abstained.
- Those who voted against the resolution: Belarus, Bolivia, Central African Republic, China, Cuba, Iran, Nicaragua, Russia, and Syria.
- Countries with abstention: The nine abstentions were India, Laos, Madagascar, Pakistan, Serbia, Sri Lanka, Sudan, Togo, and Zimbabwe.
Provisions of the resolution over the ban of ASAT
- No binding effect but urges to prevent arms race in outer space: The ASAT test-ban resolution has no binding effect on states and simply calls on states to put a stop to ASAT tests and to develop further practical steps and contribute to legally binding instruments on the prevention of an arms race in outer space.
- Other space related resolutions also passed: Along with the ASAT test-ban resolution that was passed on December 7, there were several more space- and nuclear-related resolutions, including No First Placement of Weapons in Outer Space (NFP).
- Support to minimize risks in space: Indeed, the resolution continues to support the broader efforts at developing “further practical steps” to minimize risks in space.
What is ASAT?
- ASATs (Anti-Satellite Weapons): According to a document of the United Nations Institute for Disarmament Research (UNIDIR), ASATs (Anti-Satellite Weapons) are aimed at destroying or disabling space assets, whether military or civilian, offensive or defensive.
- They are generally of two types: kinetic and non-kinetic.
- Kinetic ASATs: They must physically strike an object in order to destroy it. Examples of kinetic ASATs include ballistic missiles, drones or any item launched to coincide with the passage of a target satellite. This means any space asset, even a communications satellite, could become an ASAT if it is used to physically destroy another space object.
- Non-kinetic ASATs: A variety of nonphysical means can be used to disable or destroy a space object. These include frequency jamming, blinding lasers or cyberattacks. These methods can also render an object useless without causing the target to break up and fragment absent additional forces intervening.
Why ASAT tests are to be banned?
- Threat to peaceful utilization of outer space: ASAT tests represent a direct threat to peaceful utilization of outer space on which everyone in the global community depends.
- Threat to safety of satellites: In recent years, there has been a spurt in activities that threaten the safety and functioning of satellites. The November 15, 2021, ASAT test by Russia, which destroyed the Cosmos 1408 satellite, is a case in point.
- Space debris a potential hazard to Space station: The test created about 1,800 tracked pieces of space debris and possibly many more pieces that are difficult to track, and a hazard for astronauts aboard the International Space Station
- Rare, high-tech, and risky to test: ASAT is an anti-satellite weapon that can target enemy satellites, blinding them or disrupting communications besides providing a technology base for intercepting ballistic missiles.
Way ahead
- There are other initiatives underway in the U.N., such as the Open-Ended Working Group (OEWG) on reducing space threats through norms, rules, and principles of responsible behaviours.
- Like the ASAT test ban, these are needed to make progress on the broader space security agenda.
- Whether a legal measure or a norm, states have to take small preventative steps before space becomes completely a warfighting domain.
Conclusion
- Given the worsening space security conditions, with more countries pursuing development of ASATs and other counterspace capabilities, it is time that more countries join the current initiative to stop further ASAT tests. Unless countries can make a conscious decision to come together and work on ways to halt the current trends with regard to space weaponization, continued access to outer space is not a given.
Mains question
Q. What are ASATs? There is growing momentum behind a global moratorium on destructive kinetic anti-satellite (ASAT) tests. In light of this discuss Why ASAT must be banned?

India test-fires Agni-V Ballistic Missile amid LAC heat
Note4Students
From UPSC perspective, the following things are important :
Prelims level: Agni Missiles
Mains level: LAC skirmishes
India successfully carried out the night trials of the Agni V nuclear-capable ballistic missile days after Indian and Chinese troops clashed in Tawang district of Arunachal Pradesh.
Why in news?
- It was a midnight test fire.
- And there are rumours about the increased range and stealth capabilities of Agni-V missile.
Agni Missiles
- Agni missiles are long range, nuclear weapons capable surface to surface ballistic missile.
- The first missile of the series, Agni-I was developed under the Integrated Guided Missile Development Program (IGMDP) and tested in 1989.

Arihant SLBM launch: Enhancing India’s underwater capability
Note4Students
From UPSC perspective, the following things are important :
Prelims level: INS Arihant ,SLBM
Mains level: Security Challenges,Indias naval capability.
Context
- On October 14, India joined a select group of nations when it announced the successful launch of an SLBM (submarine-launched ballistic missile). The other six nations that have demonstrated similar underwater capability include the five permanent members of the UN Security Council Russia, the UK, France and China. In August 2016, North Korea claimed a successful launch of an SLBM.
Features of K-15 SLBM
- The code names K-15 or B-05, is an Indian submarine-launched ballistic missile (SLBM) with a range of 750 kilometres (466 mi) that was designed for retaliatory nuclear strikes. It belongs to the K Missile family and forms a part of India’s nuclear triad.
- The K-15 is a two-stage submarine-launched ballistic missile which uses a gas booster to eject out of its launch platform and rise up to the surface of water. A solid rocket motor is fired after the missile reaches a fixed altitude. The missile has a range of around 750 kilometres (466 mi).
About INS Arihant
- Launched in 2009 and Commissioned in 2016, INS Arihant is India’s first indigenous nuclear powered ballistic missile.
- It is capable submarine built under the secretive Advanced Technology Vessel (ATV) project, which was initiated in the 1990s.
- INS Arihant and its class of submarines are classified as ‘SSBN’, which is the hull classification symbol for nuclear powered ballistic missile carrying submarines.
- While the Navy operates the vessel, the operations of the SLBMs from the SSBN are under the purview of India’s Strategic Forces Command, which is part of India’s Nuclear Command Authority.
What is the Significance of SLBM for India?
- Making India’s strategic profile strong: This achievement is significant in the context of India’s strategic profile. The navy, DRDO and other agencies who have enabled this success should be commended.
- Enhancing Underwater deterrence: A credible underwater deterrent is perceived as being invulnerable to detection and hence nations with the capacity can deliver a retaliatory second strike this enhances their deterrence capabilities.
- Showcasing the precision and high accuracy: While the press release is sparse in providing technical details or confirming the range of the SLBM, its assertion that the missile impacted the target area “with very high accuracy” is, nevertheless, instructive.
- Familiarity and capability with SLMB : The crew of the INS Arihant and the entire HR (human resource) comprising the pyramid from the SFC (strategic forces command) going right up to the national command authority with the Prime Minister at the apex have acquired the necessary proficiency to launch an SLBM should the exigency arise.
- Demonstration of competence: India can be justifiably proud of having acquired and demonstrated this level of competence, but this achievement needs to be located objectively. An SSBN (a nuclear-propelled submarine armed with a nuclear-tipped ballistic missile) is deemed to be the ultimate deterrent and this profile of macro-lethality and zero error credibility is predicated on the robustness of the “boat” and the efficacy of the missile.
- Validates SSBN programme: The successful user training launch of the SLBM by INS Arihant is significant to prove crew competency and validate the SSBN programme, a key element of India’s nuclear deterrence capability. A robust, survivable and assured retaliatory capability is in keeping with India’s policy to have ‘Credible Minimum Deterrence that underpins its ‘No First Use’ commitment.
What is the deterrence?
- Deterrence, military strategy under which one power uses the threat of reprisal effectively to preclude an attack from an adversary power. With the advent of nuclear weapons, the term deterrence largely has been applied to the basic strategy of the nuclear powers and of the major alliance systems.
How the SLBM will secure deterrence against the enemy?
- Tackling to rising Chinese capability: It merits recall that China became nuclear weapon capable in 1964 and carried out its first SLBM test (the J-1 with a range of 1700 km) in 1982. Over the years, the PLA Navy had its own techno-strategic challenges with nuclear-propelled submarines and was able to test a 9,000 km missile only in 2018. It is understood that a fully armed Chinese SSBN that would be deemed to be operational to undertake a credible deterrence patrol is scheduled for mid-2025.
- Nuclear deterrence is necessary: Acquiring the optimum degree of nuclear deterrence is imperative for India, given its distinctive spectrum of security and strategic challenges. India has made slow but steady progress in its missile programme, nuclear weapon capability, the nuclear submarine and more recently the building of an aircraft carrier
Conclusion
- India’s restraint in relation to announcements and claims about strategic capability burnishes deterrence in a quiet but effective manner. Walking softly, while wielding a big stick is desirable as a national trait.
Mains Question
Q. How the launch of K-15 SLBM will enhance the security dynamics of India? Discuss the India’s underwater capability to maintain deterrence and security at the same time?

Vertical Launch Short Range Surface-to-Air Missile (VL-SRSAM)
Note4Students
From UPSC perspective, the following things are important :
Prelims level: VL-SRSAM
Mains level: Short range missiles development
The Defence Research and Development Organisation (DRDO) and the Indian Navy has successfully flight-tested the indigenously developed Vertical Launch Short Range Surface-to-Air Missile (VL-SRSAM) from the Integrated Test Range (ITR) at Chandipur off the coast of Odisha.
What is Vertical Launch Short Range Surface-to-Air Missile (VLSRSAM) ?
- VL-SRSAM has been designed and developed jointly by three facilities of the DRDO for deployment of Indian Naval warships.
- The missile has the capability of neutralising various aerial threats at close ranges including sea-skimming targets.
- The tactic of sea skimming is used by various anti-ship missiles and some fighter jets to avoid being detected by the radars onboard warships.
- For this, these assets fly as close as possible to sea surface and thus are difficult to detect and neutralise.
Features of VL-SRSAM
- The missile has been designed to strike at the high-speed airborne targets at the range of 40 to 50 km and at an altitude of around 15 km.
- Its design is based on Astra missile which is a Beyond Visual Range Air to Air missile.
- Two key features of the VL-SRSAM are cruciform wings and thrust vectoring.
- The cruciform wings are four small wings arranged like a cross on four sides and give the projective a stable aerodynamic posture.
- The thrust vectoring is an ability to change the direction of the thrust from its engine control the angular velocity and the attitude of the missile.
- VL-SRSAM is a canisterised system, which means it is stored and operated from specially designed compartments.
- In the canister, the inside environment is controlled, thus making its transport and storage easier and improving the shelf life of weapons
Strategic significance of the missile
- The launch was conducted from a vertical launcher against an electronic target at a very low altitude.
- The flight path of the vehicle along with health parameters was monitored using a number of tracking instruments deployed by ITR, Chandipur.
- The successful testing of these systems was crucial for future launches of the missile from Indian Naval Ships.

21 Years of BrahMos Missile
Note4Students
From UPSC perspective, the following things are important :
Prelims level: BrahMos Missile System
Mains level: Not Much
On June 12, 2001 the BrahMos supersonic cruise missile was first tested from a land-based launcher in Chandipur.
What is BrahMos Missile System?
- BrahMos is a joint venture between India’s Defence Research and Development Organisation (DRDO) and Russia’s NPO Mashinostroyeniya.
- The missile derives its name from the Brahmaputra and Moskva rivers.
- Beginning with an anti-ship missile, several variants have since been developed.
- It is now capable of being launched from land, sea, sub-sea and air against surface and sea-based targets and has constantly been improved and upgraded.
Its capabilities
- BrahMos is a two-stage missile with a solid propellant booster engine.
- Its first stage brings the missile to supersonic speed and then gets separated.
- The liquid ramjet or the second stage then takes the missile closer to three times the speed of sound in cruise phase.
- The missile has a very low radar signature, making it stealthy, and can achieve a variety of trajectories.
- The ‘fire and forget’ type missile can achieve a cruising altitude of 15 km and a terminal altitude as low as 10 m to hit the target.
Background and development
- The early 1980s the Integrated Guided Missile Development Programme was conceived and led by Dr A P J Abdul Kalam.
- It started developing a range of missiles including Prithvi, Agni, Trishul, Akash and Nag, with a wide spectrum of capabilities and ranges.
- In the early 1990s, India’s strategic leadership felt the need for cruise and guided missiles.
- The need was felt primarily following the use of cruise missiles in the Gulf War.
- An Agreement was signed with Russia in Moscow in 1998 by Dr Kalam, who headed the DRDO.
- This led to the formation of BrahMos Aerospace, a joint venture between DRDO and NPO Mashinostroyenia (NPOM), the Indian side holding 50.5% and the Russians 49.5%.
Tests and induction
- In 1999, work on development of missiles began in labs of DRDO and NPOM after BrahMos Aerospace received funds from the two governments.
- The first successful test in 2001 was conducted from a specially designed land-based launcher.
- The missile system has since reached some key milestones, with the first major export order of $375 million received from the Philippines Navy this year.
Strategic significance
- Cruise missiles such as BrahMos, called “standoff range weapons”, are fired from a range far enough to allow the attacker to evade defensive counter-fire.
- What makes the missile system unparalleled is its extreme accuracy and versatility.
- With missiles made available for export, the platform is also seen as a key asset in defence diplomacy.
Variants of Brahmos
- Versions currently being tested include ranges up to 350 km, as compared to the original’s 290 km.
- Versions with even higher ranges, up to 800 km, and with hypersonic speed are said to be on cards.
- Efforts are also on to reduce the size and signature of existing versions and augment its capabilities further.
- Versions deployed in all three Armed forces are still being tested regularly, and so are versions currently under development.
- LAND-BASED: The land-based BrahMos complex has four to six mobile autonomous launchers, each with three missiles on board that can be fired almost simultaneously. They are described as ‘tidy’ as they have very few components.
- SHIP-BASED: The Navy began inducting BrahMos on its frontline warships from 2005. These can hit sea-based targets beyond the radar horizon. The Naval version has been successful in sea-to-sea and sea-to-land modes.
- AIR-LAUNCHED: On November 22, 2017, BrahMos was successfully flight-tested for the first time from a Sukhoi-30MKI against a sea-based target in the Bay of Bengal. It has since been successfully tested multiple times.
- SUBMARINE-LAUNCHED: This version can be launched from around 50 m below the water surface. The canister-stored missile is launched vertically from the pressure hull of the submarine and uses different settings for underwater and out-of-the-water flights.

The Ministry of Defence has signed a contract with Bharat Dynamics Ltd (BDL) for the supply of the Astra Mark-1for deployment on fighter jets of the Indian Air Force and Indian Navy.
Astra Missile
- The Astra Mk-1 is a beyond visual range (BVR), air-to-air missile (AAM).
- The Astra project was officially launched in the early 2000s with defined parameters and proposed future variants.
- The missile has been designed and developed by the Defence Research and Development Organisation (DRDO).
- It will be deployed on fighter jets like Sukhoi-30 MKI and Tejas of the IAF and the Mig-29K of the Navy.
- BVM missiles are capable of engaging beyond the range of 20 nautical miles or 37 kilometres.
Range and its Variants
- While the range for Astra Mk-1 is around 110 km, the Mk-2 with a range over 150 km is under development and Mk-3 version with a longer range is being envisaged.
- One more version of Astra, with a range smaller than Mk-1 is also under development.
Strategic significance
- The missile has been designed based on requirements specified by the IAF for BVR as well as close-combat engagement, reducing the dependency on foreign sources.
- AAMs with BVR capability provides large stand-off ranges to own fighter aircraft.
- It can neutralise adversary airborne assets without exposing adversary air defence measures.
- Stand-off range means the missile is launched at a distance sufficient to allow the attacking side to evade defensive fire from the target.
- Astra is technologically and economically superior to many such imported missile
- The missile can travel at speeds more than four times that of sound and can reach a maximum altitude of 20 km, making it extremely flexible for air combat.

India has acknowledged a malfunction led to accidental firing of a missile, which Pakistan says landed in its territory.
Conducting Missile Tests: NOTAM and NAVAREA Warnings
- Under the pre-notification of flight testing of ballistic missiles agreement signed in 2005, a country must provide the other an advance notification on flight test it intends to take for any land or sea launched, surface-to-surface ballistic missile.
- Before the test, the country must issue Notice to Air Missions (NOTAM) or Navigational Warning (NAVAREA) to alert aviation pilots and seafarers, respectively.
- Also, the testing country must ensure that the launch site is not within 40 km, and the planned impact area is not within 75 km of either the International Boundary (IB) or the Line of Control (LoC).
- The planned trajectory should not cross the IB or the LoC and must maintain a horizontal distance of at least 40 km from the border.
Pre-notifications to the neighbours
- The testing country must notify the other nation “no less than three days in advance of the commencement of a five day launch window within which it intends to undertake flight tests.
- The pre-notification has to be conveyed through the respective Foreign Offices and the High Commissions, as per the format annexed to this Agreement.
What is the recent case of misfire?
- Neither country has spelt this out; Pakistan has only called it a “supersonic” missile.
- Some experts have speculated that it was a test of one of India’s top missiles, BrahMos, jointly developed with Russia.
- Their assessment is based on information that it travelled 200 km, manoeuvred mid-air and travelled at 2.5 times to 3 times the speed of sound at an altitude of 40,000 feet.
| Note: BrahMos has a top speed of Mach 3, a range of around 290 km, and a cruising altitude of 15 km (around 50,000 feet). It can be fired from anywhere, is nuclear-capable, and can carry warheads of 200-300 kg. |

Q. Hypersonic missiles are nothing but weapons of deterrence. Critically comment in context of arms race development for hypersonic missiles.
History of Missile Technology in India
(1) Pre-Independence
- Before Independence, several kingdoms in India were using rockets as part of their warfare technologies.
- Mysore ruler Hyder Ali started inducting iron-cased rockets in his army in the mid-18th century.
- By the time Hyder’s son Tipu Sultan died, a company of rocketeers was attached to each brigade of his army, which has been estimated at around 5,000 rocket-carrying troops.
(2) Post-Independence
- At the time of Independence, India did not have any indigenous missile capabilities.
- The government created the Special Weapon Development Team in 1958.
- This was later expanded and called the Defence Research and Development Laboratory (DRDL), which moved from Delhi to Hyderabad by 1962.
- In 1972, Project Devil, for the development of a medium-range Surface-to-Surface Missile was initiated.
- By 1982, DRDL was working on several missile technologies under the Integrated Guided Missiles Development Programme (IGMDP).
What kind of missiles does India have?
- India is considered among the top few nations when it comes to designing and developing missiles indigenously.
- However, it is way behind the US, China and Russia in terms of range.
- DRDO is working on multiple varieties of missiles:
[A] Surface-launched Systems
ANTI-TANK GUIDED MISSILE:
- Nag has already been inducted into the services. Nag is the only fire-and-forget ATGM meeting all weather requirements for its range (around 20 km).
- Recently Heli-Nag was tested, which will be operated from helicopters and will be inducted by 2022.
- There is also a Stand-off Anti-Tank (SANT) missile, with a range over 10 km.
SURFACE-TO-AIR MISSILE
- Short-range SAM system: Akash has already been inducted in the Army and the Air Force.
- For Akash 1, which has a seeker, the Army has already got the Acceptance of Necessity from the government.
- For Akash (New Generation), the first tests were conducted in July this year and a couple more trials are to be done.
- Medium-Range SAM: Production of MRSAM systems for the Navy is complete, and it is placing its order.
[B] Air-launched Systems
AIR-TO-AIR:
- Astra, India’s Beyond Visual Range Air-to-Air Missile (BVRAAM), has been completely tested and is under induction.
- It has a range of around 100 km, and DRDO is trying to now induct it with more IAF platforms, including the domestically developed light combat aircraft Tejas.
- A long-range Astra is also being developed, for which initial tests have been conducted.
- The missile uses solid fuel ramjet technology, which enhances speed, and will have an indigenously-built seeker.
AIR-TO-GROUND:
- Rudram, a New Generation Anti-Radiation Missile (NGRAM), has cleared initial tests and some more tests will be conducted soon.
- With a maximum range of around 200 km, the missile mainly targets communication, radar and surveillance systems of the adversary, and was tested from the Sukhoi-30MKI fighter jet last year.
- BrahMos, which India developed jointly with Russia, is already operational.
- It has a 300 km to 500 km range, and is a short-range, ramjet-powered, single warhead, supersonic anti-ship or land attack cruise missile.
India’s crucial missile systems
The two most important are Agni and Prithvi, both being used by the Strategic Forces Command.
- Agni (range around 5,000) is India’s only contender for an inter-continental ballistic missile (ICBM), which is available in only a few countries.
- Prithvi, although a short-range surface-to-surface missile with a 350 km range, has strategic uses. India also tested an anti-satellite system in April 2019.
- A modified anti-ballistic missile named Prithvi Defence Vehicle Mk 2 was used to hit a low-orbit satellite.
- It put India only behind the US, Russia and China in this capability.
What about Hypersonic Technology?
- India has been working on this for a few years, and is just behind the US, Russia and China.
- DRDO successfully tested a Hypersonic Technology Demonstrated Vehicle (HSTDV) in September 2020, and demonstrated its hypersonic air-breathing scramjet technology.
- India has developed its own cryogenic engine and demonstrated it in a 23-second flight.
- India will try to make a hypersonic cruise missile, using HSTDV.
- Only Russia has proven its hypersonic missile capability so far, while China has demonstrated its HGV capacity.
- India is expected to be able to have a hypersonic weapons system within four years, with medium- to long-range capabilities.
What makes India good in missile technology?
- Missile technology is one field in which India has made very positive and substantial progress.
- Under the IGMP then headed by A P J Abdul Kalam, later India’s President, first came Prithvi, then Agni.
- BrahMos, at 2.5-3 times the speed of sound, was among the fastest in the world when developed.
- After the nuclear blast in 1998, cryogenic etc were not given to us by developed countries. Kalam and others, they made it a point that they developed it within the country.
Where do China and Pakistan stand compared to India?
- While China is ahead of India, a lot of things about China are psychological.
- China may have either achieved parity or even exceeded the US in land-based conventional ballistic and cruise missile capabilities.
- China’s missile development is definitely a concern for us, but we will definitely evolve.
- It has given the technology to the irresponsible hands of Pakistan. But getting technology and really using it, and thereafter evolving and adopting a policy is totally different.

Arms Race towards Hypersonic Weapons
Note4Students
From UPSC perspective, the following things are important :
Prelims level: Hypersonic Glide Vehicle, ICBM
Mains level: Hypersonic weapons race
China recently tested a nuclear-capable hypersonic missile while Russia announced that it had successfully test-launched a Tsirkon hypersonic cruise missile in early October.
What are Hypersonic Weapons?
- The speed of sound is Mach 1, and speeds upto Mach 5 are supersonic and speeds above Mach 5 are hypersonic.
- They are manoeuvrable weapons that can fly at speeds in excess of Mach 5, five times the speed of sound.
- A number of other countries – including Australia, India, France, Germany, and Japan—are developing hypersonic weapons technology.
Features of HSWs
- Trajectory: Ballistic Missiles are long-range missile that leaves the earth’s atmosphere before re-entry, pursuing a parabolic trajectory towards its target
- Maneuverability: HSW travel within the atmosphere and can manoeuvre midway which combined with their high speeds make their detection and interception extremely difficult.
- Stealth: Radars and air defences cannot intercept them till they are very close. They can penetrate most missile defences and further compress the timelines for response by a nation under attack.
Types of Hypersonic Weapons
There are two classes of hypersonic weapons:
- Hypersonic glide vehicles (HGV): They are launched from a rocket before gliding to a target.
- Hypersonic cruise missiles (HCM): They are powered by high-speed, air-breathing engines, or scramjets, after acquiring their target.
Where does the US stand?
- The US has active hypersonic development programs.
- It is said to be lagging behind China and Russia because most US hypersonic weapons are not being designed for use with a nuclear warhead.
- It is in process of developing prototypes to assist in the evaluation of potential weapon system concepts and mission sets.
Hypersonic program in India
- HSTDV program: India is developing an indigenous, dual-capable hypersonic cruise missile as part of its Hypersonic Technology Demonstrator Vehicle (HSTDV) program.
- Capacity: India operates approximately 12 hypersonic wind tunnels and is capable of testing speeds of up to Mach 13.
- In-operation: The DRDO has successfully tested a Mach 6 scramjet in June 2019 and September 2020 using the demonstrated scramjet engine technology.
DRDO has validated many associated crucial technologies such as:
- Aerodynamic configuration for hypersonic maneuvers
- Use of scramjet propulsion for ignition and sustained combustion at the hypersonic flow
- Thermo-structural characterization of high-temperature materials
- Separation mechanism at hypersonic velocities has been validated
Conclusion
- There are rising tensions between the US, China and Russia worsening the geopolitical situation worldwide.
- The focus for hypersonic weapons is only set to accelerate more countries to invest significant resources in their design and development.

Agni V vs China’s Hypersonic Missile
Note4Students
From UPSC perspective, the following things are important :
Prelims level: Hypersonic Glide Vehicle, ICBM
Mains level: Hypersonic Glide Missiles
Though inducted over three years ago, India’s foremost Agni 5 ballistic missile was tested for the first time after reports that China had tested a new hypersonic missile.
What is the Agni 5 missile?
- Agni 5 is India’s long-range surface-to-surface ballistic missile, which can hit a target with a precision that is 5,000 km
- The nuclear-capable missile is India’s contender for the Intercontinental Ballistic Missile (ICBM).
- Its range puts almost the entire China within the missile’s target range.
- Though the government has claimed that it has a maximum range of around 5,000 km, several reports suggest that it can hit targets as distant as 8,000 km.
- The nuclear capable missile can carry a warhead of around 1,500 kg and has a launch weight of 50,000 kg, making it one of the most potent missiles in the country.
Note: Officially an ICBM needs a missile to have a range of at least 5,500 km.
History of Agni Missiles
- India began testing the Agni series of missiles in 1989 with the first test for Agni 1, an Intermediate-Range Ballistic Missile, with a range of around 1,000 km.
- At that time only the US, the erstwhile Soviet Union, China, France and Israel, had IRBM technology.
- Since then, DRDO labs have continued to work on it, bringing the latest available Agni 5 to its present capability.
- In addition to the IRBM-capable nations, only North Korea and the UK have ICBM technology at the moment.
Why is it important for India?
- The success of AGNI missiles is in line with India’s stated policy to have ‘credible minimum deterrence’ that underpins the commitment to ‘No First Use’.
- What makes Agni 5 agile is that it is a “canisterised” missile. It means that the missile can be launched from road and rail platforms, making it easier for it to be deployed and launched at a quicker pace.
- The canisterisation also gives the missile a longer shelf life, protecting it from the harsher climatic conditions.
- While India is among the handful of nations with ICBM capability.
- The next generation of the missile, Agni VI, under development, is expected to have a range of around 8,000 km.
What is a Hypersonic Glide Vehicle that China tested?
- HGV is nuclear capable missile, which circled the earth before moving towards its target, missing it by two dozen miles.
- It is launched by a rocket which moves in the Earth’s lower orbit, at more than five times to 25 times the speed of sound.
- The vehicle is capable of carrying nuclear payloads, which gives the launching country the strategic capacity to attack almost any target across the world.
How is HGV different from an ICBM?
- A hypersonic glide vehicle orbits the earth at a lower height, and is manoeuvrable as compared to ICBM.
- The ability to change track or target, mid-trajectory, along with the speed, makes them tougher to track and defend against.
- The manoeuvrability provides them in-flight updates to attack a different target than originally planned.
- They possess ability to fly at unpredictable trajectories, these missiles will hold extremely large areas at risk throughout much of their flights.
Which countries have hypersonic technology?
- Apart from China, the US and Russia are working on the technology.
- France and India are working together for gaining the capability.
Concerns about China developing such technology
- China might have left the US behind in hypersonic capability.
- It is being perceived as a Sputnik moment (first Russian space mission widely envied by the US).
- A hypersonic attack could occur with very little warning time. The unpredictable trajectory would give them an advantage.
Another concern: Increasing Proliferation
- Globally the main concern is that once the technology is successfully established by even one country, it would lead to a larger race for the capability and its eventual proliferation.
- The more that hypersonic missiles proliferate into the hands of additional nations, the more paths develop for crises.

Anti Radiation Missile: RudraM-I
Note4Students
From UPSC perspective, the following things are important :
Prelims level: RudraM-I
Mains level: India's missile arsenal
A New Generation Anti Radiation Missile (NGARM), RudraM-I, was successfully flight-tested by the Defence Research and Development Organisation (DRDO).
Try this MCQ:
Q.The RudraM-I recently seen in news is an:
Ans: Anti-satellite missile/ Anti-radiation Missile/ Anti-tank mine/ Submarine Torpedo
RudraM-I
- RudraM-I is an anti-radiation missile can locate and target any radiation-emitting source like enemy radars, communication sites and other Radio Frequency (RF) emitting targets.
- It is being developed by Defence Research Development Laboratory (DRDL), Hyderabad, as the nodal agency.
- It is a joint effort involving several DRDO labs, the IAF, the Hindustan Aeronautics Limited (HAL) and several public and private sector enterprises.
- This is the first indigenous anti-radiation missile of the country. It has a range of up to 200 km depending upon the launch conditions.
- It can be launched from altitudes of 500 m to 15 km and speeds of 0.6 to 2 mach.
- It can play a key role in neutralizing any jamming platforms of the enemy or take out radar stations thereby clearing a path for own fighters to carry out an offensive and also prevent own systems from being jammed.
How does it work?
- Anti-radiation missiles are designed to detect, track and neutralize the adversary’s radar, communication assets and other radio frequency sources, which are generally part of their air defence systems.
- Such a missile’s navigation mechanism comprises an inertial navigation system — a computerised mechanism that uses changes in the object’s own position — coupled with GPS, which is satellite-based.
- For guidance, it has a “passive homing head” — a system that can detect, classify and engage targets (radio frequency sources in this case) over a wide band of frequencies as programmed.
- Once the RudraM missile locks on the target, it is capable of striking accurately even if the radiation source switches off in between.

Q.The SMART system recently tested by the DRDO is essentially a-
a)Radar
b)Torpedo
c)UAV
d)Missile
What is the SMART system?
- Torpedoes are self-propelled weapons that travel underwater to hit a target but are limited by their range.
- In the mid-2010s, DRDO undertook a project to build capacity to launch torpedoes assisted by missiles; Monday’s was the first known flight test of the system.
- This SMART system comprises a mechanism by which the torpedo is launched from a supersonic missile system with modifications that would take the torpedo to a far longer range than its own.
- For example, a torpedo with a range of a few kilometres can be sent a distance to the tune of 1000 km by the missile system from where the torpedo is launched.
Why is it significant?
- SMART is a game-changing technology demonstration in anti-submarine warfare.
- India’s anti-submarine warfare capacity building is crucial in light of China’s growing influence in the Indian Ocean region.
- Assets of such warfare consist of the deployment of submarines, specialised anti-submarine ships, air assets and state-of-the-art reconnaissance and detection mechanisms.
- The Navy’s anti-submarine warfare capability got a boost in June after the conclusion of a contract for Advanced Torpedo Decoy System Maareech, capable of being fired from all frontline warships.
- India has been indigenously developing and building several anti-submarine systems and vessels in the recent past.

Shaurya Missile and India’s K missiles family
Note4Students
From UPSC perspective, the following things are important :
Prelims level: Shaurya Missile
Mains level: India's missile programme
A successful trial of the nuclear-capable Shaurya missile was conducted by India.
Shaurya Missile
- Shaurya is a land-based parallel of the submarine-launched K-15 missile.
- It is a land variant of short-range SLBM K-15 Sagarika, which has a range of at least 750 kilometres.
- These ballistic weapons belong to the K missile family — codenamed after late Dr APJ Abdul Kalam — which is launched from Arihant class of nuclear submarines.
- Because these missiles are to be launched from submarines, they are lighter, smaller and stealthier than their land-based counterparts; the Agni series.
A look at what this family of missiles is their strategic importance as a nuclear deterrent and their recent tests.
K Family of missiles
- The K family of missiles is primarily Submarine Launched Ballistic Missiles (SLBMs), which have been indigenously developed by DRDO.
- These are named after Dr Kalam, the central figure in India’s missile and space programmes who also served as the 11th President of India.
- The development of this naval platform launched missiles began in the late 1990s as a step towards completing India’s nuclear triad (land, sea and air-based).
Strategic importance of SLBMs
- The capability of being able to launch nuclear weapons submarine platforms has great strategic importance in the context of achieving a nuclear triad, especially in the light of ‘no first use’ policy of India.
- The sea-based underwater nuclear-capable assets significantly increase the second strike capability of a country and thus boosts its nuclear deterrence.
- These submarines can not only survive the first strike by the adversary but also can launch a strike in retaliation thus achieving Credible Nuclear Deterrence.
- The development of these capabilities is important in light of India’s relations with the two neighbours China and Pakistan.

Hypersonic Technology Demonstrator Vehicle (HSTDV)
Note4Students
From UPSC perspective, the following things are important :
Prelims level: Ramjet, Scramjet
Mains level: Indian missile program
The DRDO has successfully demonstrated the hypersonic air-breathing scramjet technology with the flight test of the Hypersonic Technology Demonstration Vehicle (HSTDV).
Take note of close dissimilarities between Ramjet and Scramjet engines.
About HSTDV
- HSTDV is an unmanned scramjet vehicle with a capability to travel at six times the speed of sound.
- The scramjets are a variant of a category of jet engines called the air-breathing engines.
- The ability of engines to handle airflows of speeds in multiples of the speed of sound gives it a capability of operating at those speeds.
- Hypersonic speeds are those which are five times or more than the speed of sound.
- The unit tested by the DRDO can achieve upto six times the speed of sound or Mach 6, which is well over 7000 km per hour or around two km per second.
Its development
- The DRDO started on the development of the engine in the early 2010s.
- The ISRO has also worked on the development of the technology and has successfully tested a system in 2016. DRDO too has conducted a test of this system in June 2019.
- The special project of the DRDO consisted of contributions from its multiple facilities including the Pune headquartered Armament and Combat Engineering Cluster.
Back2Basics: Ramjet V. Scramjet
- A ramjet is a form of air-breathing jet engine that uses the vehicle’s forward motion to compress incoming air for combustion without a rotating compressor.
- Fuel is injected in the combustion chamber where it mixes with the hot compressed air and ignites.
- A ramjet-powered vehicle requires an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust.
- Ramjets work most efficiently at supersonic speeds around Mach 3 (three times the speed of sound) and can operate up to speeds of Mach 6.
- However, the ramjet efficiency starts to drop when the vehicle reaches hypersonic speeds.
- A scramjet engine is an improvement over the ramjet engine as it efficiently operates at hypersonic speeds and allows supersonic combustion. Thus it is known as Supersonic Combustion Ramjet or Scramjet.

K-4 Missile
Note4Students
From UPSC perspective, the following things are important :
Prelims level: K-4 Missile, Circular Error Probability
Mains level: India's missile nuclear arsenal
India successfully test-fired the 3,500-km range submarine-launched ballistic missile, K-4. The test was carried out by the DRDO from a submerged pontoon off the Visakhapatnam coast around noon.
K-4
- K-4 is a nuclear-capable Intermediate-range submarine-launched ballistic missile developed and tested successfully in the month of January 2020 by DRDO.
- The missile has a maximum range of about 3500 km.
- Once inducted, these missiles will be the mainstay of the Arihant class of indigenous ballistic missile nuclear submarines (SSBN).
- It will give India the standoff capability to launch nuclear weapons submerged in Indian waters.
What’s so special about K-4?
: Circular Error Probability
- India’s Circular Error Probability (CEP) is much more sophisticated than Chinese missiles.
- The CEP determines the accuracy of a missile.
- The lower the CEP, the more accurate the missile is.
- There are very few countries which have managed to achieve this technological breakthrough.
About INS Arihant
- The Advanced Technology Project (ATV) began in the 1980s and the first of them, Arihant, was launched in 2009.
- INS Arihant, the first and only operational SSBN is armed with K-15 Sagarika missiles with a range of 750 km.
- Given India’s position of ‘No-First-Use’ (NFU) in launching nuclear weapons, the SSBN is the most dependable platform for a second-strike.
- Because they are powered by nuclear reactors, these submarines can stay underwater indefinitely without the adversary detecting it.
- The other two platforms — land based and air launched are far easier to detect.
