Key Highlights
- MIGM showcases India’s autonomous underwater weapon capability.
- It fuses magnetic, acoustic and pressure sensing to neutralise covert submarines and ships.
- A live‑fire test with a reduced charge confirmed operational readiness.
- The programme embodies the Aatmanirbhar Bharat ethos through collaboration between DRDO laboratories and industry.
Detailed Insights
Multi‑Influence Ground Mine (MIGM) is an advanced undersea explosive designed to detect and engage stealth submarines and surface vessels. It employs a hybrid sensor suite that reacts to magnetic, acoustic and hydrostatic pressure signatures, allowing it to autonomously lock onto a target before detonation.
Undersea Warfare Enhancement derives from MIGM’s ability to operate silently, thereby reducing the risk of detection by adversarial sonar systems. The mine’s reduced-charge trials demonstrate a balance between lethality and safety for friendly vessels nearby.
DRDO’s Naval Science & Technological Laboratory (NSTL), along with High Energy Materials Research Laboratory (HEMRL) and Terminal Ballistics Research Laboratory (TBRL), devised the core technology. Production partners Bharatiya Dynamics Limited (BDL) and Apollo Microsystems Limited have progressed the mine from prototype to field‑ready status, reinforcing India’s strategic deterrence in the Indian Ocean.
Key Concepts
- Multi‑Influence Ground Mine (MIGM): A submerged naval mine that integrates multiple sensor modalities for target detection and engagement.
- Undersea Warfare: Combat operations conducted beneath the water surface, involving submarines, torpedoes, mines and related technologies.
- Aatmanirbhar Bharat: India’s self‑reliance policy aimed at reducing dependence on foreign defence technology.
- Magnetic Signature: The field profile produced by a vessel’s hull and onboard equipment, detectable by magnetic sensors.
- Acoustic Signature: The unique pattern of sound waves emitted by a submarine or surface ship, used for passive detection.
