Working as part of Indian Naval Hydrographic Department the Sandhayak-class survey ships are equipped with a range of surveying, navigational and communication systems. The ships are designed to undertake shallow coastal and deep oceanic hydrographic survey and collect oceanographic and geophysical data required for the production of digital navigational charts and publications. Besides carrying out their primary role of hydrographic survey, they can also assist in times of war and natural calamities as troop transports and casualty holding ships. The ships are also equipped with ROV, AUV & USV.[4] Nirdeshak was decommissioned in 2014.[5]
