In 2005, India chose the Scorpène design; purchasing six submarines for US$3 billion ($500 million per boat) under the Project 75 (P75). The project was necessitated by the dwindling number of submarines in the Indian Navy. Indian Navy needed replacement for the older Sindhughosh (Kilo) and Shishumar (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). The submarines are to be manufactured under a technology transfer agreement by the state-owned Mazagon Docks in Mumbai. 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. 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 taken to make up for the delay. As per the current schedule, the first Scorpène submarine will be delivered in September 2016, with the other five boats following at 10–12 months intervals each. The first Scorpène submarine, INS Kalvari (named after a deep sea tiger shark), has been launched and she will start sea trials in 2015. 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.
