Indian Navy Trials Advanced Indigenous AUVs for Enhanced Maritime Surveillance

October 2024

The Indian Navy recently concluded extensive trials of indigenously developed Autonomous Underwater Vehicles (AUVs) in the Arabian Sea. These trials, involving platforms from DRDO and private Indian firms, focused on validating capabilities for long-duration intelligence, surveillance, and reconnaissance (ISR) missions, as well as mine countermeasure (MCM) operations. The successful integration of advanced sonar payloads and AI-driven navigation systems marks a significant step towards achieving self-reliance in unmanned underwater systems. This development directly supports India's broader strategy for bolstering maritime domain awareness (MDA) and securing its vast Exclusive Economic Zone (EEZ) against evolving threats.

UPSC Angle: This event highlights India's commitment to defence indigenisation ('Make in India') and its strategic focus on enhancing naval capabilities. UPSC aspirants should analyze the implications for India's maritime security, its role in the Indo-Pacific, and the technological advancements in AI and robotics driving these platforms. Questions could arise on the types of AUVs, their applications in naval warfare, and the policy support for indigenous development.

DRDO Unveils Next-Gen Underwater Glider for Oceanographic Research

March 2025

DRDO, in collaboration with the National Institute of Oceanography (NIO), has unveiled a prototype of a new long-endurance underwater glider designed for persistent oceanographic data collection. This buoyancy-driven AUV can operate for months, collecting critical data on ocean temperature, salinity, currents, and marine biology. The glider's low power consumption and stealthy operation make it ideal for climate change monitoring and understanding complex ocean dynamics. This initiative aligns with India's Deep Ocean Mission and its scientific exploration goals, emphasizing sustainable use of marine resources.

UPSC Angle: This development showcases India's dual-use technology approach, where defence research contributes to civilian scientific endeavors. For UPSC, this connects to topics like climate change, blue economy, oceanography, and the role of scientific institutions. Questions might focus on the technology behind underwater gliders, their environmental applications, and India's broader scientific missions in the ocean.
