Naval Anti-Ship Missile Short Range (NASM-SR)

Context:

Recently, the Indian Navy and the Defence Research and Development Organisation (DRDO) successfully carried out the first-ever salvo launch of the Naval Anti-Ship Missile – Short Range (NASM-SR) from a naval helicopter off the coast of Odisha.

About NASM-SR:

• • • The Naval Anti-Ship Missile Short Range (NASM-SR) is an advanced air-launched anti-ship missile system developed to enhance India’s naval offensive capability.
    • Designed to replace ageing foreign-origin missiles like the British Sea Eagle
    • India’s first indigenously developed helicopter-launched anti-ship missile
    • Developed by Defence Research and Development Organisation (DRDO) through Research Centre Imarat (RCI), Hyderabad, along with other DRDO labs
    • Strengthens self-reliance in naval strike systems

Key Features of NASM-SR:

• • • Propulsion System
      • Solid-propellant engine
      • Ejectable booster for launch
      • Long-burn sustainer for extended flight
    • Range and Flight Profile
      • Range: ~55 km
      • Subsonic sea-skimming trajectory to evade radar detection
    • Precision Strike Capability
      • Designed for waterline hits, targeting a ship’s hull at the most vulnerable point
      • Causes maximum flooding and structural damage
    • Guidance and Navigation
      • Fiber-optic gyroscope-based inertial navigation system
      • Radio altimeter for altitude control
      • Advanced Imaging Infra-Red (IIR) seeker for terminal precision targeting
    • Data and Control Systems
      • High-bandwidth two-way data link
      • Enables lock-on-after-launch and in-flight target reprogramming
      • Electro-mechanical actuator and jet vane control for high manoeuvrability
    • Platform Integration
      • Initially launched from Sea King helicopters
      • Future integration planned with:
        • MH-60R Seahawk
        • HAL Dhruv (Advanced Light Helicopter)

Significance of NASM-SR:

• • • Validates India’s indigenous maritime strike capability
    • Demonstrates successful salvo firing from a single platform
    • Enhances operational readiness in real combat scenarios
    • Reduces dependence on imported systems like Sea Eagle missiles
    • Strengthens ecosystem involving DRDO, MSMEs, and startups
    • Boosts India’s vision of a self-reliant defence manufacturing sector

Strategic Importance for India:

NASM-SR significantly improves India’s coastal defence and naval deterrence capability. Its sea-skimming, precision strike design makes it highly effective against enemy ships in littoral zones, supporting India’s maritime security in the Indian Ocean Region (IOR).

Conclusion:

The successful testing of NASM-SR marks a major leap in India’s indigenous defence capability. It reflects the country’s growing technological maturity in advanced missile systems and strengthens its maritime security architecture while advancing the goal of Atmanirbhar Bharat in defence production.
