The Defence Research and Development Organisation (DRDO) has successfully developed a new generation of Man-Portable Autonomous Underwater Vehicles (MP-AUVs) for mine countermeasure missions. These systems have been designed by the Naval Science & Technological Laboratory (NSTL), Visakhapatnam, a premier DRDO establishment responsible for underwater naval systems. MP-AUVs mark a major step in enhancing India’s underwater surveillance and mine-neutralisation capability.

The MP-AUV system comprises multiple autonomous underwater vehicles, each equipped with advanced sensors for underwater mine detection.

Primary payloads include:

• Side Scan Sonar – for seabed mapping and mine-like object detection
• Underwater Cameras – for visual identification and classification

These vehicles incorporate deep learning-based target recognition algorithms, enabling autonomous classification of underwater threats. This reduces operator workload, enhances accuracy, and shortens mission duration. The system also integrates a robust underwater acoustic communication network, allowing AUV-to-AUV data exchange and enabling networked operations. This improves situational awareness and allows coordinated search patterns without direct human control.

The MP-AUV design prioritisesrapid response capability and low logistical footprint, making it suitable for deployment from small naval vessels or shore platforms. Its man-portable nature allows fast mobilisation and reduces operational risk by minimising diver involvement in hazardous minefields. Field trials conducted at NSTL/harbour sites have successfully validated key performance parameters, including detection accuracy, communication reliability and autonomous navigation.

This development aligns closely with India's push for indigenous defence technologies and intelligent autonomous systems. It enhances operational readiness in underwater mine warfare and supports the broader goal of strengthening maritime security. DRDO, headquartered in New Delhi and established in 1958, continues to lead India’s indigenous defence R&D, focusing on strategic capabilities and advanced naval systems.
