When visitors saw India’s Anti-Satellite weapon displayed at DefExpo 2020, one message was clear: India had developed the ability to target and destroy a satellite in space.
The display followed India’s successful Mission Shakti test on 27 March 2019. However, one important fact needs clarification. India did not destroy an enemy satellite during the test. It used an Indian target satellite to demonstrate its ability to intercept a satellite in Low Earth Orbit.
The test made India the fourth country after the United States, Russia and China to demonstrate a destructive Anti-Satellite, or ASAT, capability. 1
What Is India’s Anti-Satellite Weapon?
An Anti-Satellite weapon is designed to disable, damage or destroy satellites in orbit. Satellites are now critical for:
- Military communication
- Navigation and timing
- Intelligence, surveillance and reconnaissance
- Weather forecasting
- Banking and financial networks
- Television and internet connectivity
- Disaster management
- Agriculture and infrastructure planning
India’s ASAT capability is a ground-launched, direct-ascent kinetic interceptor. It does not remain permanently stationed in space. Instead, a missile is launched from the ground and guided towards a satellite travelling in orbit.
The interceptor destroys the target through the force of a high-speed collision. This is known as a kinetic hit-to-kill method.
Mission Shakti: Key Facts
| Feature | Details |
|---|---|
| Mission | Mission Shakti |
| Date | 27 March 2019 |
| Lead organisation | Defence Research and Development Organisation |
| Weapon type | Ground-launched kinetic ASAT interceptor |
| Missile origin | Derived from India’s Ballistic Missile Defence programme |
| Target | An Indian orbiting satellite |
| Orbit | Low Earth Orbit, approximately 300 km |
| Method | Hit-to-kill kinetic impact |
| Result | Successful satellite interception |
| Strategic outcome | India became the fourth country to demonstrate a destructive ASAT capability |
The official Ministry of Defence release stated that a DRDO-developed Ballistic Missile Defence interceptor engaged an Indian target satellite in Low Earth Orbit. The three-stage interceptor used a hit-to-kill mechanism and completed all mission objectives. 5
Prime Minister Narendra Modi said the satellite was hit within approximately three minutes of the missile’s launch and described Mission Shakti as an indigenously developed capability. 3
Which Satellite Was Destroyed in Mission Shakti?
The immediate official statements described the target only as an Indian orbiting satellite. The satellite is widely identified as Microsat-R, an imaging satellite that ISRO launched on 24 January 2019.
ISRO’s own mission record describes Microsat-R as an imaging satellite launched by PSLV-C44 into a low orbit. 1
For accuracy, an article should therefore say:
“Mission Shakti destroyed an Indian target satellite, widely identified as Microsat-R.”
It is better than presenting the test as the destruction of an enemy satellite. The 2019 test demonstrated the capability; it was not a wartime engagement against another country’s spacecraft.
How Does an ASAT Missile Work?
A direct-ascent ASAT missile generally follows four broad stages:
1. Target Detection and Tracking
The target satellite’s orbit is monitored using radar, optical sensors and tracking systems. A satellite moves at several kilometres per second, so the interceptor must calculate the future point at which the missile and satellite will meet.
2. Missile Launch
The interceptor is launched from a ground facility. Unlike a conventional ballistic missile, its objective is not to strike a target on Earth. It must reach the satellite’s orbital path at the correct time and angle.
3. Mid-Course Guidance
The missile’s guidance system continuously adjusts its trajectory. The interceptor has to account for the speed, direction and changing position of the satellite.
4. Kinetic Interception
The kill vehicle collides with the satellite at very high speed. The impact energy is sufficient to break apart the spacecraft without requiring a conventional explosive warhead.
The Ministry of External Affairs said India used a DRDO Ballistic Missile Defence interceptor because India had developed the required kinetic-interception technology through its missile-defence programme. 2
Technical literature commonly identifies the interceptor used in the test as a modified Prithvi Defence Vehicle Mark-II, although official government releases generally describe it as a DRDO-developed BMD interceptor.
Why Was Mission Shakti Important for India?
1. Strategic Deterrence
India’s satellites support communication, navigation, surveillance and military operations. An adversary capable of attacking those satellites could affect military command systems, intelligence collection and battlefield connectivity.
Mission Shakti demonstrated that India could potentially threaten an adversary’s satellite architecture in a conflict. This creates a deterrence effect: an opponent must consider the consequences of attacking Indian space assets.
The Indian government described the capability as a way to safeguard India’s growing space-based infrastructure and national interests. 2
2. Entry into an Exclusive Group
Before Mission Shakti, the United States, Russia and China had publicly demonstrated destructive ASAT capabilities. India became the fourth country to conduct such a demonstration. This gave India greater strategic weight in discussions on space security and the prevention of an arms race in outer space.
3. Validation of Indigenous Technology
The test brought together technologies developed for:
- Ballistic missile defence
- Long-range tracking
- Precision guidance
- High-speed target acquisition
- Interceptor control
- Ground-based radar and range instrumentation
It showed that India could combine missile and space technologies without relying on a foreign launch or interceptor system.
4. Protection of National Infrastructure
The modern economy depends heavily on satellites. A disruption to communication, navigation or Earth-observation systems can affect defence, transport, financial services, weather forecasting and disaster response.
In that sense, India’s ASAT capability is linked not only to military power but also to the protection of critical national infrastructure.
Does India’s ASAT Weapon Protect Satellites?
Not directly.
This is one of the most important distinctions in the discussion around India’s Anti-Satellite weapon.
An ASAT missile is a counter-space weapon. It can potentially disable or destroy an adversary’s satellite, but it cannot form a physical shield around an Indian satellite. It also cannot stop every kind of space attack.
For example, an ASAT interceptor may not prevent:
- Satellite communication jamming
- GPS or NavIC spoofing
- Cyberattacks on mission-control systems
- Laser dazzling of optical sensors
- Attacks on ground stations
- Supply-chain compromise
- Co-orbital satellite interference
- Space debris collisions
Therefore, a complete Indian space-defence architecture requires more than one missile. It needs space surveillance, secure communication, cyber defence, electronic warfare protection, satellite redundancy and the ability to rapidly replace damaged satellites.
Space Debris: The Major Risk of Kinetic ASAT Tests
The biggest criticism of destructive ASAT tests is the creation of orbital debris.
India conducted Mission Shakti at a relatively low altitude, close to 300 km. The government said the lower altitude was deliberately selected so that debris would experience atmospheric drag and re-enter the atmosphere within weeks. 2
However, independent tracking produced a more cautious picture. U.S. military sensors initially tracked at least 270 fragments from the event, while space-security assessments noted that more than 100 trackable pieces were generated and that some fragments remained in orbit for an extended period. 5 1
The balanced conclusion is that India’s choice of a low altitude likely reduced the long-term persistence of much of the debris, but it did not make the test completely debris-free.
This matters because even a small piece of debris can travel at several kilometres per second. A collision between debris and an operational satellite can cause serious damage and generate additional fragments.
The danger of a chain reaction of collisions is commonly associated with the Kessler Syndrome, in which debris makes certain orbital regions increasingly difficult or dangerous to use.
Is India’s ASAT Weapon Legal?
India’s official position is that Mission Shakti did not violate any international law or treaty obligation. The Ministry of External Affairs also stated that the test was not directed against any particular country. 2
The 1967 Outer Space Treaty prohibits placing nuclear weapons and other weapons of mass destruction in orbit or stationing them in outer space. Article IV does not create a comprehensive, explicit ban on every conventional, ground-based ASAT system. 1
However, this does not mean that all destructive space activities are free from legal or diplomatic consequences. Other principles of international space law concern:
- Due regard for the interests of other states
- Avoiding harmful interference
- Responsibility for national space activities
- Liability for damage caused by space objects
- Long-term sustainability of outer space
Therefore, the legal debate is not limited to whether a conventional ASAT missile is explicitly banned. It also includes the environmental, security and responsibility-related consequences of creating debris.
What Is India Building Beyond the ASAT Missile?
India’s space-defence efforts are gradually expanding beyond kinetic interception.
Space Situational Awareness
ISRO’s NETRA, or Network for Space Objects Tracking and Analysis, is designed to track satellites and space debris. It uses radar, optical telescopes and a central control and analysis system to improve the safety of Indian spacecraft.
ISRO has also been developing additional radar and optical-telescope capabilities, including an optical telescope at Hanle in Ladakh and indigenous space-object tracking radar systems. 2
Electronic Warfare and Non-Kinetic Capabilities
DRDO’s publicly listed space-technology development areas include:
- Space-asset jamming
- Electronic-intelligence geolocation
- Space-based high-power lasers
- AI and machine-learning-based multisensor data fusion
- High-gain beam-steering antennas
- Free-space laser communication
- Infrared payloads for missile detection
- Rendezvous and proximity operations
- Nano-satellite attitude-control systems
These entries represent technology-development areas and should not automatically be described as fully operational weapons. 3
Military Communication Satellites
India is also strengthening the communication side of military space. GSAT-7 and GSAT-7A provide important communication capabilities for strategic users. The government has separately approved programmes for GSAT-7B for the Army and GSAT-7C for the Air Force.
GSAT-7B is intended to provide high-throughput, beyond-line-of-sight communication to troops, formations and weapon platforms. 1
Mission Shakti vs Other Types of Space Weapons
ASAT weapons are not limited to missiles. Space warfare technologies can broadly be divided into several categories:
Kinetic Weapons
These physically collide with or destroy a satellite. Mission Shakti demonstrated this category.
Electronic Weapons
These can jam or interfere with satellite communications, radar signals or navigation systems.
Cyber Weapons
These target satellite software, mission-control networks, ground stations and data links.
Directed-Energy Weapons
Lasers or high-power electromagnetic systems may damage sensors, solar panels or electronic components without creating a large debris cloud.
Co-Orbital Systems
These are spacecraft that approach another satellite in orbit and may interfere with, inspect, disable or attack it.
India’s public demonstration in 2019 was specifically a kinetic, direct-ascent ASAT capability. It should not be taken as proof that India has publicly disclosed every type of space weapon listed above.
The DefExpo 2020 Display: Why It Became a Symbol
The ASAT missile display at DefExpo 2020 attracted attention because it converted an otherwise classified and highly technical achievement into a visible defence exhibit.
The original description that the weapon could destroy an “enemy satellite” captured its strategic purpose, but the wording should be understood as a capability statement. Mission Shakti itself involved an Indian target satellite, not an enemy spacecraft.
The display symbolised three things:
- India’s entry into the group of countries with demonstrated destructive ASAT capability
- The integration of India’s missile-defence and space technologies
- A warning that India’s space assets would not be completely undefended in a future conflict
Conclusion
Yes, India has a demonstrated Anti-Satellite weapon capability.
Mission Shakti showed that a DRDO-developed Ballistic Missile Defence interceptor could be used to hit a satellite in Low Earth Orbit through a kinetic, hit-to-kill attack. The test made India the fourth country to demonstrate such a capability.
But the full meaning of India’s space defence is broader than the ASAT missile. A missile can create deterrence, but secure space power also requires:
- Reliable satellites
- Multiple and redundant constellations
- Space Situational Awareness
- Cybersecurity
- Anti-jamming systems
- Secure military communication
- Protected ground infrastructure
- Rapid satellite replacement capability
The real test for India will not simply be whether it can destroy a satellite. It will be whether India can keep its own communication, navigation and surveillance systems functioning during a prolonged crisis while also supporting responsible and sustainable use of outer space.
