The Kalvari class is a class of submarines based on the Template:Sclass2- being built for the Indian Navy. It is a class of diesel-electric attack submarine which is designed by French naval defence and energy company DCNS and being manufactured at Mazagon Dock Limited in Mumbai.
Project history
In 2005, India chose the Template:Sclass2- design; purchasing six submarines for US$3 billion ($500 million per boat) under Project 75 (P75). The project was necessitated by the dwindling number of submarines in the Indian Navy. Indian Navy needed replacement for the older Template:Sclass- (Kilo) and Template:Sclass- (U209) class of submarines. The Scorpène design won the deal, defeating the rival U214 because of the capability to fire Exocet anti-ship missiles and an agreement on the air-independent propulsion (AIP).[2] The submarines are to be manufactured under a technology transfer agreement by the state-owned Mazagon Docks in Mumbai.[3] India plans to incorporate the DRDO-developed air independent propulsion (AIP) system onto the last two submarines being built and also to equip the P75I submarines, of which the DCNS is participating in the tender process.[4]
Construction of the first submarine started on 23 May 2009. The project is running four years behind schedule. Once the new government under Prime Minister Narendra Modi took over, the project was reviewed and necessary action was taken to make up for the delay.[5]
It was reported in November 2014, that the DRDO-developed AIP system for the last two Scorpène submarines for the Indian Navy has been developed and is ready for testing in February 2015.[6] The government announced that it would soon purchase three more submarines from France to bolster India’s naval power.[7]
The first Scorpène submarine, INS Kalvari (named after a deep sea tiger shark),[8] was launched to commence sea trials in April 2015.[9]
Ships of the class
The hull fabrication of all six submarines is now complete. The first Scorpène submarine will be delivered in September 2016, delivery of successive boats have been compressed to nine months and the project is expected to be completed by 2020.[10]
