Design

edit

The ships have a displacement of 3,400 tonnes (3,346 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.[5]

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.[6][7][8][9]

Construction

edit

The keel of the ship was laid on 1 December 2020[10] and launched on 26 May 2022.[1]

The ship is expected to be delivered in 2024.[11] The ship was delivered to the Indian Navy on 8 October 2024.[2]
