replace the Chetak helicopters in service. The naval variant is fitted with the Super Vision-2000 maritime radar, capable of detecting targets with low radar cross-section at a range of . The anti-submarine version of the helicopter is fitted with dunking sonar, torpedoes, depth charges. The helicopter may also be fitted with the missiles for anti-ship roles. However, in 2008, the Indian Navy pronounced Dhruv unsuitable for its role as an ASW platform. Indian Navy will continue to procure Dhruv as a multi-role utility platform. During the commissioning ceremony Vice Admiral Sinha said that "In the Navy, Dhruv helicopters have transformed into an advanced search and rescue (SAR) helicopter also used for missions like heliborne operations, and armed patrol with night vision devices. Such machines in the inventory have become imperative for the Navy given the scenario of low-intensity maritime operations (LIMO) and coastal security construct." In 2013 Indian Navy showed keen interest in the armed version of the HAL Rudra. Impressed with the Dhruv's sensors which were able to track ships and also read their names at ranges of . The Navy may induct 20 more helicopters into service. A new squadron INAS 323 Harriers was commissioned with HAL Dhruv MKIII variant. Navy placed order for 16 MKIII helicopters and 6 of them are delivered with the remaining 10 to be delivered by Dec 2021. Naval variant of MKIII comes with 19 specific systems suited for maritime role. Kamov Ka-25, Kamov Ka-28, and the Kamov Ka-31: The Ka-25 was acquired by the Indian Navy in 1980 for anti-submarine warfare, but had severe technological limitations. The Ka-28s were acquired in the mid-80s and were said to be a quantum leap over their predecessors from an ASW standpoint. The Ka-31 takes the Kamov capabilities even further by enabling real-time network-centric warfare for the Indian Navy. Westland Sea King and the Sikorsky SH-3 Sea King: Used principally for anti-submarine warfare (ASW) and search & rescue roles, the helicopter fleet operate from INS Garuda (Kochi) as well as INS Shikra air stations. US sanctions on India in response to India's nuclear tests resulted in a large part of the Sea King fleet being grounded for want of spare parts. Seventeen of the Sea King helicopters will be upgraded. The upgrade will feature day and night capability, the capability to work in adverse weather conditions, integration of two anti-ship missiles with a range of fifty
