Anjadip
It is the third Anti-Submarine Warfare Shallow Water Craft (ASW-SWC).
Built by Garden Reach Shipbuilders & Engineers (GRSE) for Indian Navy.
The ship has been named Anjadip to signify the strategic maritime importance accorded to the island of Anjadip, located off Karwar.
The island is connected to the mainland by a breakwater and is part of INS Kadamba.
The 'Arnala' class of ships built by GRSE would replace the current 'Abhay' class of Anti-Submarine Warfare Corvettes of the Navy.
They are designed to undertake anti-submarine operations in coastal waters, low intensity maritime operations, subsurface surveillance among others.
Anti-Submarine Warfare Shallow Water Craft (ASW-SWC):
The ASW-SWC corvettes, are a class of anti-submarine warfare (ASW).
Vessels currently being built for the Indian Navy, by Cochin Shipyard (CSL) and Garden Reach Shipbuilders & Engineers (GRSE).
They were conceived as a replacement to the ageing Abhay-class corvettes of the Indian Navy.
They are designed to undertake ASW duties – including subsurface surveillance in littoral waters, search-and-attack unit (SAU) missions and coordinated anti-submarine warfare operations with naval aircraft.
They were also designed to provide secondary duties – including defense against intruding aircraft, minelaying and search-and-rescue (SAR).
Equipped with sophisticated sensors and ordnance, the vessels also possess the capabilities to interdict and destroy subsurface targets – primarily hostile submarines, within the vicinity of coastal waters.
A total of 16 vessels are being built for the Indian Navy, jointly by CSL and GRSE under the Make in India initiative.
The Indian Navy plans to have all 16 vessels in active service by 2026.
Sanshodhak
‘Sanshodhak’, the fourth of four ships of Survey Vessels (Large) (SVL) Project, being built by L and T/ GRSE for Indian Navy.
The ship named ‘Sanshodhak’, meaning ‘Researcher’, signifies the primary role of the ship as a Survey Vessel.
SVL ships will replace the existing Sandhayak Class survey ships, with new generation hydrographic equipment, to collect oceanographic data.
The Survey Vessel (Large) ships are 110 m long, 16 m wide with a displacement of 3,400 tons.
The hull of these ships is made from indigenously developed DMR 249-A steel manufactured by Steel Authority of India Limited.
Capability to carry four Survey Motor Boats and an integral helicopter.
Survey Vessels (Large) (SVL) Ships:
The primary role of the ships would be to undertake full scale coastal and deep-water hydrographic surveys of Ports and navigational channels.
The ships would also be deployed for collecting oceanographic and geophysical data for defence as well as civil applications.
In their secondary role, the ships are capable of providing limited defence, HADR, and can serve as Hospital ship during emergencies.
