Kalvari is one of Indian Navy’s 6 Scorpene class stealth submarines which has been developed indigenously.
Defence Minister Parrikar had launched the submarine in March last year for sea trials where the vessel has sailed for over 1,000 hours till now.
Commissioning into Indian Navy is expected by March 2017.
With Commissioning of INS Kalvari, Indian Navy is also breaking apart from age old tradition, where earlier the shipyards would hand over warships to the Navy and then would continue trials on the systems on board and the vessels would be made fighting fit long after their official induction.
“The defence ministry is of the view that the vessels should be commissioned in service only if they are ready for deployment in operations moments after they are commissioned into the service,”
The 6 Scorpenes are being constructed by Mazgaon Docks Ltd in partnership with a firm from France, DCNS under Project 75
This project’s delivery was first scheduled in 2012 but has been delayed considerably
Defence ministry has announced that the P75 project can also invite private players for a JV which will assist in the early completion of the project
Features of Kalvari
This Scorpene submarine has superior stealth technology
It can also launch massive attacks through precision guided weapons
An attack can be launched through this submarine with torpedoes as well as tube launched anti-ship missiles on the surface of the water or beneath it as well
This submarine works in all settings including the tropics, wherein various means and communications are in place to ensure interoperability with various components of the naval task force
Numerous defence activities can be carried out through this stealth submarine including mine laying, area surveillance, anti-submarine warfare, intelligence gathering and multifarious warfare activities
This Scorpene submarine is constructed from special steel and it can withstand high yield stress because it possesses tensile strength, it can withstand hydrostatic force of high magnitude and dive deeper
Kalvari and other submarines in this class are also equipped with WLT/Weapons Launching tubes and these can carry weapons on board which can effectively be reloaded at sea
All six submarines including Kalvari are being indigenously constructed at Mazgaon Dockyard Ltd in Mumbai
The last and may be second last attack submarine of these class will be equipped with air independent propulsion
The new diesel electronic Scorpene submarines will be named as per the old Foxtrot class boats decommissioned around 10 years ago; these were the first submarines of the Navy
INR Kalvari is one of a set of six submarines which is undergoing test and trials for last one and a half years rigorously at harbour and on sea whether on the surface or underwater
Mechanisms on this submarine have been designed to optimise safety; DRDO is in the process of establishing a system for carrying out structural health monitoring of under development nuclear submarines as well as future conventional Naval submarines
To speed up India in the race for naval vessels, the NDA government has ordered for an accelerated tendering process to construct 6 conventional diesel electric submarines at a cost estimated to be INR 50,000 crore or USD 8.1billion alongside the Scorpenes.
