Beneath the Hull, India’s Navy Is Adding a New Pair of Robotic Eyes

India’s push for indigenous defence technology is moving underwater. The Indian Navy has taken delivery of two TROUT remotely operated vehicles developed by Kochi-based marine robotics startup EyeROV, marking the deployment of what the company calls India’s first indigenously designed and qualified military-grade underwater ROV.

The two systems are part of an order for five TROUT platforms. They are built for underwater inspection, surveillance, reconnaissance, search and recovery, detection and robotic intervention — missions that can become difficult or hazardous for personnel in deep water, poor visibility and strong underwater currents.

Before delivery, TROUT underwent field trials and system-level validation covering manoeuvrability, navigation, endurance, operator control and performance in demanding underwater conditions. The platform also went through the Directorate of Quality Assurance (Naval) framework and environmental-stress qualification required for military use.

The significance goes beyond another equipment order. Underwater inspections around ships, harbours and critical maritime infrastructure have traditionally relied heavily on human divers, particularly when identifying damage, obstructions or other anomalies below the waterline. ROVs can extend that inspection capability into environments where sending personnel may be slower or riskier.

EyeROV, formally IROV Technologies, was founded in 2016 and develops remotely operated vehicles, autonomous underwater systems, unmanned surface vehicles and marine-data software. Its platforms are already used across infrastructure inspection, offshore energy, research and maritime applications.

For EyeROV, TROUT’s entry into naval service represents a shift from building underwater robots for specialised inspection toward supplying equipment qualified for sustained defence operations. For India’s marine robotics ecosystem, it is another sign that domestically developed systems are beginning to move from prototypes and trials into operational procurement.
