Naval Anti-Ship Missile–Medium Range (NASM–MR)

Latest News

India recently achieved a major milestone in defence technology by successfully conducting the maiden flight test of the Naval Anti-Ship Missile–Medium Range (NASM–MR).

During the same series of trials, India also successfully tested its multi-layered Ballistic Missile Defence (BMD) System, demonstrating significant progress in strengthening the country's maritime and strategic defence capabilities.

About NASM–MR

The Naval Anti-Ship Missile–Medium Range (NASM–MR) is an indigenously developed subsonic, sea-skimming anti-ship missile being designed by the Defence Research and Development Organisation (DRDO) for the Indian Navy. It is intended to destroy small- and medium-sized enemy warships, including frigates, corvettes, and destroyers, thereby enhancing India's maritime strike capability.

The missile is being developed in multiple variants, including ship-launched, air-launched, and submarine-launched versions.

It complements the Naval Anti-Ship Missile–Short Range (NASM–SR), creating a layered anti-ship strike capability that enables the Navy to engage hostile vessels at both close and medium ranges.

Key Features

The missile is powered by an indigenously developed Small Gas Turbine Jet Engine (SGTJE), providing efficient propulsion and sustained flight performance. It follows a sea-skimming flight profile, flying just above the sea surface to evade enemy radar detection and improve survivability against naval air defence systems.

NASM–MR has an operational range of up to 350 km, enabling the Indian Navy to engage hostile ships from a safe stand-off distance. It carries a warhead weighing over 200 kg, capable of inflicting significant damage on enemy surface combatants.

The missile is equipped with an advanced dual-mode guidance system, integrating an Active Radar Seeker with an Imaging Infrared (IIR) Seeker. This combination enhances target acquisition, tracking accuracy, and resistance to electronic countermeasures, while ensuring all-weather operational capability.

Strategic Significance

NASM–MR significantly strengthens India's maritime strike capability by providing a modern, indigenous weapon system capable of engaging enemy warships at medium ranges. The availability of ship-, submarine-, and aircraft-launched variants offers greater operational flexibility and supports the Indian Navy's network-centric warfare doctrine.

The missile also advances the goals of Aatmanirbhar Bharat by reducing dependence on imported anti-ship missiles and promoting indigenous defence manufacturing. It complements long-range systems such as BrahMos, providing commanders with multiple strike options against different categories of naval targets.

India's Multi-Layered Ballistic Missile Defence (BMD) System

About the BMD System

India's Ballistic Missile Defence (BMD) Programme, developed by DRDO, is designed to detect, track, and destroy incoming ballistic missiles before they reach their targets. The system provides multi-layered protection by intercepting enemy missiles both inside the Earth's atmosphere (Endo-atmospheric interception) and outside the atmosphere (Exo-atmospheric interception).

The recent trials were conducted under Phase II of the BMD programme, focusing on the advanced AD-series interceptors, which are capable of intercepting Intermediate-Range Ballistic Missiles (IRBMs) and even Intercontinental Ballistic Missiles (ICBMs) of the 5,000-km class.

AD-1 Interceptor

The AD-1 interceptor is an endo-atmospheric interceptor designed to destroy incoming ballistic missiles during the terminal phase of their flight within the Earth's atmosphere. It is powered by a two-stage solid-propellant rocket motor and employs advanced navigation, guidance, and control algorithms to intercept both high-speed ballistic missiles and slower-moving aerial targets.

AD-2 Interceptor

The AD-2 interceptor is an exo-atmospheric interceptor designed to engage ballistic missiles during their mid-course phase outside the Earth's atmosphere. By destroying hostile missiles in space before re-entry, it provides an additional protective layer and significantly improves the probability of successful interception.

Both AD-1 and AD-2 are capable of travelling at hypersonic speeds of Mach 6–7, enabling them to intercept highly manoeuvrable and fast-moving ballistic missile threats.

Strategic Importance

The successful testing of the AD-series interceptors places India among a select group of countries possessing an indigenous multi-layered Ballistic Missile Defence capability. The system enhances India's strategic deterrence by providing protection against advanced ballistic missile attacks, including IRBMs and ICBMs, thereby strengthening national security and safeguarding critical military and civilian infrastructure.
