India achieved a significant milestone in naval defence technology with the successful flight trials of its first Naval Anti-Ship Missile (NASM-SR). The missile, developed by the Defence Research and Development Organisation (DRDO) in collaboration with the Indian Navy, was launched from a Sea King helicopter at the Integrated Test Range (ITR) in Chandipur. This successful test demonstrates India’s growing indigenous missile development capabilities and strengthens the nation’s maritime security framework.

Key Features of NASM-SR: A New Era in Naval Warfare

The NASM-SR (Naval Anti-Ship Missile – Short Range) is a first-of-its-kind missile designed to enhance the Indian Navy’s precision strike capability. Some of its standout features include:

• Man-in-Loop Technology: This allows in-flight retargeting, enabling the pilot to select or change targets even after launch.
• Indigenous Imaging Infra-Red Seeker: Used for terminal guidance, ensuring high precision in targeting.
• High Bandwidth Two-Way Data Link: Transmits live seeker images back to the pilot, assisting in effective decision-making.
• Bearing-Only Lock-on Mode: The missile can lock onto a target after launch, even when multiple potential targets are nearby.
• Mid-Course Guidance System: Features an indigenous Fiber Optic Gyroscope-based Inertial Navigation System (INS) and Radio Altimeter for accurate trajectory control.
• Advanced Warhead and Propulsion: Uses a solid propulsion system, featuring an in-line ejectable booster and long-burn sustainer for extended range and endurance.

Precision Targeting and Flight Capabilities

The successful NASM-SR trial was conducted in a sea-skimming mode, a technique where the missile flies low over the water to avoid radar detection, making it harder for enemy ships to intercept. The Man-in-Loop feature was successfully tested, proving that the missile could be retargeted mid-flight.

During the test, the missile initially locked onto a large ship target within a specified zone. However, during the terminal phase, the pilot was able to redirect it toward a smaller hidden target, hitting it with pinpoint accuracy. This demonstrates the missile’s capability to distinguish and prioritize multiple targets in a combat scenario, a crucial feature in modern naval warfare.

Developed by DRDO’s Leading Defence Labs

The NASM-SR missile is the result of extensive research by multiple DRDO labs, including:

• Research Centre Imarat (RCI) – Developed the guidance and control system.
• Defence Research and Development Laboratory (DRDL) – Worked on the propulsion and structural integrity of the missile.
• High Energy Materials Research Laboratory (HEMRL) – Developed the solid propulsion system and warhead technology.
• Terminal Ballistics Research Laboratory (TBRL) – Focused on impact dynamics and penetration capabilities.

The missile is currently in production with the support of Development cum Production Partners (DcPPs), Micro, Small & Medium Enterprises (MSMEs), startups, and other production partners, making it a key example of India’s self-reliance in defence manufacturing.

India’s Growing Naval Defence Capabilities

With increasing maritime security challenges, India is strengthening its naval deterrence. The successful testing of NASM-SR brings several strategic advantages:

1. Enhanced Naval Combat Readiness: The NASM-SR provides the Indian Navy with a powerful anti-ship missile to counter threats at sea.
2. Indigenous Defence Advancement: The development and successful trial of NASM-SR signify India’s progress in indigenous missile technology, reducing reliance on foreign systems.
3. Strengthened Defence Exports: India’s expertise in developing advanced missile systems could pave the way for exports to friendly nations, reinforcing India's role as a global defence supplier.

Defence Minister Rajnath Singh’s Statement

Following the successful missile trials, Union Defence Minister Rajnath Singh congratulated DRDO, the Indian Navy, and the entire defence industry for their contributions. He emphasized that the Man-in-Loop feature is a game-changer, allowing for in-flight retargeting, which is critical for precision strikes in complex naval battle scenarios.

A Major Step Towards Self-Reliance in Defence

The successful NASM-SR flight trial marks a major step in India’s Atmanirbhar Bharat (Self-Reliant India) initiative. With the Indian defence sector focusing on indigenous research, development, and production, India is poised to become a global leader in advanced missile systems and naval warfare technology.

As India continues to expand its defence capabilities, the successful test of NASM-SR serves as a strong message of technological progress and strategic preparedness in safeguarding the nation's maritime interests.
