Indian Navy’s fifth Kalvari-class Diesel Electric attack submarine INS Vagir was launched at Mazgaon Dock in Mumbai on Thursday. A look at this modern and stealthy class of submarines having been built under Project 75 and whose design is based on the Scorpene class of the submarines.
Indian Naval Ship (INS) Vagir, launched on Thursday, is the fifth among the six Kalvari-class submarines being constructed by the public sector shipbuilder Mazagon Dock Ltd (MDL) in Mumbai.
The other vessels in the class are INS Kalvari, INS Khanderi, INS Karanj, INS Vela and INS Vagsheer. Of these Kalvari and Khanderi have been commissioned in 2017 and 2019, Vela and Karanj and undergoing sea trials, Vagir has now been launched and Vagsheer is under construction.
After its launch today, Vagir will commence with the setting to work of various equipment and the Harbour Acceptance Trials. The crew will subsequently sail the submarine for the Sea Acceptance Trials after which the submarine would be delivered to the Navy.
The submarines in the current Kalvari-class take their names from erstwhile decommissioned classes of submarines named Kalvari which included Kalvari, Khanderi, Karanj and Vela class — which included Vela, Vagir, Vagshir. The now-decommissioned Kalvari and Vela classes were one of the earliest of the submarines in post independence Indian Navy, which belonged to Soviet origin Foxtrot class of vessels.
Launch of a vessel is the process of transferring the ship from dockyard to water and is different from the commissioning of the ship, when it actually enters the active service.
