The '''Project 75I-class submarine''' is a follow-on of the ''Project 75'' [[Kalvari-class submarine]] for the [[Indian navy]].<ref name=":0"/> Under this project, the Indian Navy intends to acquire 6 diesel-electric submarines, which will also feature advanced [[Air Independent Propulsion]] (AIP) systems to enable them to stay submerged for longer duration and substantially increase their operational range.<ref name=":0" /><ref name="financialexpress.com">{{Cite web|url = http://www.financialexpress.com/article/companies/govt-shortlists-larsen-toubro-pipavav-for-rs-6000-cr-submarine-contract/51455/|title = Narendra Modi government shortlists Larsen & Toubro, Pipavav for Rs 60,000 crore submarine contract|date = |accessdate = |website = |publisher = |last = |first = }}</ref> In October 2014, the project got clearance from Defence Acquisition Council.<ref name=":1" /> All six submarines are expected to be constructed in Indian shipyards.<ref name="financialexpress.com"/>

== History ==
In October 2008, the Indian Navy issued a Request for Information (RFI) to a number of foreign shipyards and design firms for construction of a class of advanced diesel-electric submarines. The RFIs were sent to [[Rosoboronexport]], [[DCNS (company)|Armaris]] and [[Howaldtswerke-Deutsche Werft|HDW]], among others.<ref name=":0" /><ref>{{Cite web|url = http://www.globalsecurity.org/military/world/india/project-76.htm|title = Project-75A / Project-75I / Project 76|date = |accessdate = |website = |publisher = |last = |first = }}</ref> Originally the navy intended to purchase two submarines directly from the foreign vendor, with four licence-built at chosen local Indian shipyards in order to save time.<ref name="janes.com">{{Cite web|url = http://www.janes.com/article/43166/delays-force-indian-navy-to-shake-up-project-75i-submarine-plans|title = Delays force Indian Navy to shake up Project 75I submarine plans|date = |accessdate = |website = |publisher = |last = |first = }}</ref> Acceptance of Necessity was accorded to the project by the Defence Acquisition Council in August 2011. In December 2014, the new NDA government fast-tracked the bidding process for Project 75I due to mounting concerns over increasing [[People's Liberation Army Navy]] activities in the Indian Ocean region.<ref name=":0" /><ref>{{Cite web|url = http://in.reuters.com/article/2014/11/02/sri-lanka-china-submarine-idINKBN0IM0LU20141102|title = Chinese submarine docks in Sri Lanka despite Indian concerns|date = |accessdate = |website = |publisher = |last = |first = }}</ref> and diminishing submarine strength of the Indian navy.<ref>{{Cite news|url = http://www.business-standard.com/article/economy-policy/a-powerful-surface-navy-lacks-sub-punch-114100101407_1.html|title = A powerful surface navy lacks sub punch|last = |first = |date = |work = |access-date = |via = }}</ref> Later it was decided to construct all six submarines in Indian shipyards in accordance with the [[Make in India]] initiative of the government.

== Design ==
The Project 75I-class submarines will have a [[Vertical launch system|vertical launch system(VLS)]] to enable them to carry multiple [[Brahmos]] supersonic [[cruise missile]]s, making the submarines fully capable of [[Anti-surface warfare|anti-surface]] and [[Anti-ship missile|anti-ship]] warfare missions. Project 75I submarines will also be armed with torpedoes and will feature advanced stealth capabilities such as a greater ability to suppress noise and acoustic signatures.<ref name=":1" /> Submarines will also be outfitted with [[Air-independent propulsion|Air-independent propulsion (AIP)]] fuel cells which can significantly increase submerged endurance and operational range.<ref>{{Cite web|url = http://ibnlive.in.com/blogs/sauravjha/2976/65437/a-look-at-the-indian-navys-project-75i-tender-to-makeinindia-six-dieselelectric-submarines.html|title = A look at the Indian Navy's Project 75I tender to #MakeinIndia six diesel-electric submarines|date = |accessdate = |website = |publisher = |last = |first = }}</ref>

== Progress ==
After years of delays,<ref name="janes.com"/> in October 2014, Project 75l was cleared by the Defence Acquisition Council. {{INRConvert|53000|c|0}} was allocated for the acquisition of 6 advanced attack submarines.<ref name=":1">{{Cite web|url = http://www.ndtv.com/india-news/6-made-in-india-submarines-for-navy-for-53-000-crores-684137|title = 6 Made-in-India Submarines for Navy for 53,000 Crores|date = |accessdate = |website = |publisher = |last = |first = }}</ref> During the bidding process, a high-level committee was set up by the Ministry of Defence (MoD) to inspect and assess the capabilities of different local shipyards to undertake the building of six submarines. The committee shortlisted 5 shipyards which include [[Hindustan Shipyard]], [[Mazagon Dock Limited|Mazagon Dock]], [[Garden Reach Shipbuilders and Engineers]] (GRSE), [[Larsen & Toubro]] and [[Pipavav Shipyard]]. These shipyards are expected to be submitting their bids in partnership with an international shipyard and the Indian navy will choose a design and shipyard which meets its specifications.<ref>{{Cite web|url = http://www.sunday-guardian.com/news/5-shipyards-earmarked-for-rs-53000-crore-sub-project|title = 5 shipyards earmarked for Rs 53,000 crore sub project|date = |accessdate = |website = |publisher = |last = |first = }}</ref><ref>{{Cite web|title = Govt shortlists 5 shipyards for Rs 64,000-cr submarines project|url = http://www.hindustantimes.com/business/govt-shortlists-5-shipyards-for-rs-64-000-cr-submarines-project/story-SqYgNvGj4OgNShufzxDHuM.html|website = http://www.hindustantimes.com/|accessdate = 2016-01-03}}</ref>
