The Ministry of Defence on Saturday confirmed the successful flight-trial of an advanced Agni-5 missile equipped with Multiple Independently Targetable Re-entry Vehicle (MIRV) technology from Dr APJ Abdul Kalam Island on Friday.
According to the ministry, the missile was tested with multiple payloads aimed at different targets spread across a large geographical area in the Indian Ocean Region. The ministry stated that the successful trial demonstrated India’s capability to strike multiple strategic targets using a single missile system.
MIRV technology enables a ballistic missile to carry several nuclear warheads capable of independently striking different targets, while also improving the missile’s ability to evade defence systems.
Defence Minister Rajnath Singh congratulated the Defence Research and Development Organisation, the Indian Army and industry partners involved in the test. He said the development would strengthen India’s defence preparedness amid growing security concerns.
The ministry said telemetry and tracking during the flight-trial were conducted through multiple ground and ship-based stations, which monitored the missile from launch until all payloads reached their targets. According to the ministry, flight data confirmed that all mission objectives were achieved.
The nuclear-capable Agni-5 has an officially declared strike range of over 5,000 kilometres, allowing it to target regions deep inside Asia, including China, along with parts of Europe and Africa.
The missile was developed by DRDO laboratories with support from industries across India. Senior DRDO scientists and Indian Army personnel witnessed the test.
An ICBM generally operates in three phases. During the boost phase, rocket motors propel the missile upward at high speed. In the midcourse phase, the missile exits the atmosphere and travels through space. During the terminal phase, warheads re-enter the atmosphere at hypersonic speeds before striking targets.
The defining feature of an ICBM is its strategic reach and ability to ensure retaliatory capability during a nuclear conflict.
For example, Mach 1 equals the speed of sound, while Mach 10 refers to ten times the speed of sound. Modern hypersonic weapons generally travel above Mach 5.
The high speed of ballistic missile warheads during re-entry makes interception difficult because of limited reaction time and extreme velocity.
India recently tested a Long Range Anti-Ship Hypersonic Missile reportedly capable of speeds close to Mach 10, reflecting a wider focus on survivable high-speed weapons.
Under this system, warheads separate during the midcourse phase and independently re-enter the atmosphere before striking different locations.
Strategically, MIRV systems allow a single missile to overwhelm missile defence networks, threaten multiple targets simultaneously and improve the survivability of deterrence capabilities.
Countries such as the United States, Russia and China already operate MIRV-capable missile systems. India demonstrated this capability through Mission Divyastra linked to the Agni missile programme.
Agni-I was primarily focused on Pakistan-centric deterrence, while Agni-II and Agni-III extended India’s strike reach toward China.
Agni-IV improved mobility and survivability, while Agni-5 introduced canister-launch capability and extended operational range.
The proposed Agni-VI is expected to combine longer range, MIRV capability, mobile launch platforms and canister-based deployment systems to improve launch readiness and survivability.
Reports suggest the missile may have a strike range exceeding 10,000 kilometres.
Strategic experts argue that despite India’s existing deterrence capability against China and Pakistan, longer-range missiles strengthen survivability and assured retaliation by allowing launch systems to operate from deeper within Indian territory.
The expansion of Chinese missile infrastructure, missile defence systems and mobile launch capabilities has also sharpened focus on India’s future deterrence requirements.
MIRV capability is considered particularly significant because it complicates interception efforts by forcing adversaries to deal with several incoming warheads simultaneously.
India officially continues to follow a doctrine of credible minimum deterrence and no-first-use. However, evolving missile technologies, hypersonic systems, missile defence networks and space-based surveillance are increasingly influencing global strategic calculations.
The current discussions around Agni-VI and MIRV technology indicate India’s focus on ensuring long-term deterrence capability, survivability and operational readiness in a changing global security environment.

Second known MIRV-capable Agni-5 test
The latest trial marked the second known test of the advanced MIRV-capable Agni-5 variant, also referred to as “Mission Divyastra”. The first such test took place in March 2024.The nuclear-capable Agni-5 has an officially declared strike range of over 5,000 kilometres, allowing it to target regions deep inside Asia, including China, along with parts of Europe and Africa.
The missile was developed by DRDO laboratories with support from industries across India. Senior DRDO scientists and Indian Army personnel witnessed the test.
What is an ICBM?
An Intercontinental Ballistic Missile (ICBM) is a long-range missile designed to travel beyond 5,000 kilometres. Unlike cruise missiles, ballistic missiles spend a major portion of their journey outside the Earth’s atmosphere before re-entering during the terminal phase.An ICBM generally operates in three phases. During the boost phase, rocket motors propel the missile upward at high speed. In the midcourse phase, the missile exits the atmosphere and travels through space. During the terminal phase, warheads re-enter the atmosphere at hypersonic speeds before striking targets.
The defining feature of an ICBM is its strategic reach and ability to ensure retaliatory capability during a nuclear conflict.
Understanding Mach speed and hypersonic capability
Mach speed measures velocity relative to the speed of sound. Under normal conditions, sound travels at approximately 1,235 kilometres per hour.For example, Mach 1 equals the speed of sound, while Mach 10 refers to ten times the speed of sound. Modern hypersonic weapons generally travel above Mach 5.
The high speed of ballistic missile warheads during re-entry makes interception difficult because of limited reaction time and extreme velocity.
India recently tested a Long Range Anti-Ship Hypersonic Missile reportedly capable of speeds close to Mach 10, reflecting a wider focus on survivable high-speed weapons.
What is MIRV technology?
MIRV stands for Multiple Independently Targetable Re-entry Vehicle. Unlike conventional ballistic missiles carrying a single warhead, MIRV-capable missiles can carry multiple nuclear warheads, each directed at separate targets.Under this system, warheads separate during the midcourse phase and independently re-enter the atmosphere before striking different locations.
Strategically, MIRV systems allow a single missile to overwhelm missile defence networks, threaten multiple targets simultaneously and improve the survivability of deterrence capabilities.
Countries such as the United States, Russia and China already operate MIRV-capable missile systems. India demonstrated this capability through Mission Divyastra linked to the Agni missile programme.
Evolution of the Agni missile programme
India’s Agni missile series has gradually evolved to address changing strategic requirements.Agni-I was primarily focused on Pakistan-centric deterrence, while Agni-II and Agni-III extended India’s strike reach toward China.
Agni-IV improved mobility and survivability, while Agni-5 introduced canister-launch capability and extended operational range.
The proposed Agni-VI is expected to combine longer range, MIRV capability, mobile launch platforms and canister-based deployment systems to improve launch readiness and survivability.
Reports suggest the missile may have a strike range exceeding 10,000 kilometres.
Strategic debate around Agni-VI
Discussion around Agni-VI intensified after DRDO Chairman Samir V Kamat stated that the organisation was prepared to proceed with the programme pending government approval.Strategic experts argue that despite India’s existing deterrence capability against China and Pakistan, longer-range missiles strengthen survivability and assured retaliation by allowing launch systems to operate from deeper within Indian territory.
The expansion of Chinese missile infrastructure, missile defence systems and mobile launch capabilities has also sharpened focus on India’s future deterrence requirements.
MIRV capability is considered particularly significant because it complicates interception efforts by forcing adversaries to deal with several incoming warheads simultaneously.
Strategic signalling and future deterrence
Analysts believe the proposed Agni-VI would also carry strategic signalling value by placing India among countries possessing advanced intercontinental strike capability.India officially continues to follow a doctrine of credible minimum deterrence and no-first-use. However, evolving missile technologies, hypersonic systems, missile defence networks and space-based surveillance are increasingly influencing global strategic calculations.
The current discussions around Agni-VI and MIRV technology indicate India’s focus on ensuring long-term deterrence capability, survivability and operational readiness in a changing global security environment.
