The Naval Science & Technological Laboratory (NSTL), Visakhapatnam, under Defence Research and Development Organisation (DRDO), has developed a new generation of Man-portable Autonomous Underwater Vehicles (MP-AUVs). MP-AUVs are designed for mine countermeasure missions with Side Scan Sonar and underwater cameras as primary payloads for real-time detection and classification of Mine-Like Objects (MLOs). Deep learning-based target recognition algorithms enable autonomous classification, reducing operator workload and mission time. The system includes robust underwater acoustic communication for inter-AUV data exchange and improved situational awareness.
