Context: DRDO and the Indian Navy successfully tested the indigenous Naval Anti-Ship Missile – Short Range (NASM-SR) with a ‘Man-in-Loop’ capability from a Seaking 42B helicopter at ITR, Chandipur.
About Man-in-Loop Anti-Ship Missile:
- What is a Man-in-Loop Missile?
-
- A missile that allows real-time human intervention during flight for decision-making.
- Enables in-flight retargeting based on live seeker images sent to the pilot.
- Developed by: Defence Research and Development Organisation (DRDO) in collaboration with the Indian Navy.
- How It Works?
-
- Bearing-Only Lock-On Mode: The missile is launched with a broad direction of the target.
- Live Seeker Image Transmission: The high-bandwidth two-way data link sends real-time target images to the pilot.
- In-Flight Retargeting: The pilot can redirect the missile to a specific target based on new information.
- Sea-Skimming Mode: The missile flies low over the sea surface to avoid radar detection.
- Terminal Phase Guidance: Uses an Indigenous Imaging Infra-Red Seeker (IIR) for precision strikes.
- Key Features:
-
- Indigenous Fiber Optic Gyroscope-based Inertial Navigation System (INS) for accurate mid-course guidance.
- Electro-Mechanical Actuators & Jet Vane Control for superior maneuverability.
- Radio Altimeter for low-altitude, terrain-following flight.
- Pinpoint accuracy with a range of over 50 km.
