Locally-built dive support vessel delivered to Indian Navy

Privately-owned Indian shipbuilder Titagarh Rail Systems handed over a new catamaran dive support vessel (DSV) to the Indian Navy in a ceremony on Tuesday, September 16.

Designated A20, the vessel is one of five that Titagarh has been contracted to build for the Indian Navy. In addition to being used for dive support, the DSVs may also be used for diver training in harbours and coastal waters, marine salvage, and repair/maintenance of other vessels.

A20 has a length of 32.9 metres, a beam of 13 metres, a displacement of approximately 380 tons, and space for 18 crewmembers. Two 1,342kW engines deliver a service speed of 11 knots.

The hydrodynamic analysis and model testing of the ship during the design stage were undertaken at the Naval Science and Technological Laboratory in Visakhapatnam.

All five DSVs in the class are scheduled to be handed over to the Indian Navy by the end of the first quarter of 2026. Construction of the ships is being undertaken in compliance with the requirements of the Indian Register of Shipping.
