Design
The ships have a displacement of 3,300 tonnes (3,248 long tons) and a length of 110 metres (360 ft 11 in). They have a cruising speed of 16 knots (30 km/h; 18 mph) with a maximum speed of 18 knots (33 km/h; 21 mph) and an operating range of 6,500 nautical miles (12,000 km; 7,500 mi) at a speed of 14 to 16 knots (26 to 30 km/h; 16 to 18 mph). The ships have a complement of 231 and are equipped with hydrographic sensor equipment and a hangar which can accommodate one advanced light helicopter. In the secondary role, the ships can be fitted with a CRN 91 naval gun. In addition, the vessels will follow MARPOL (marine pollution) Standards of the International Maritime Organisation and will be built per Classification Society Rules and Naval Ship Regulations.[6]
The primary role of the vessels would be to conduct coastal and deep-water hydro-graphic survey of ports, navigational channels, Exclusive Economic Zones and collection of oceanographic data for defence. Their secondary role would be to perform search & rescue, ocean research and function as hospital ships for casualties.[7][8][9][10]
Construction
The class of the survey vessel were ordered on 30 October 2018 by the Ministry of Defence to the GRSE for its design, construction and delivery to the Indian Navy.[1] The keel of the ship was laid on 17 June 2022[2] and launched on 13 June 2023.[3] Following contractor trials and validation, she was delivered to the Indian Navy on 30 March 2026 along with INS Dunagiri and INS Agray.[5][4]
