Project-75 India

Project-75 India


  • Kickstarting the formal process for building six conventional submarines indigenously under the Project 75 India or P-75I, the government issued a Request for Proposal (RPF) to the two selected Indian Strategic Partners (SP).



  • The Defence Acquisition Council had approved the issuing of the RFP.

  • The project is worth Rs 43,000 crore and will be the first, across services, under the strategic partnership model, which was promulgated in 2017 to boost indigenous defence manufacturing.


  • Project-75(I) envisages indigenous construction of six modern conventional submarines including

    • associated shore support,

    • Engineering Support Package,

    • training and spares package

    •  contemporary equipment,

    • weapons & sensors including

    • Fuel-Cell based AIP (Air Independent Propulsion Plant),

    • advanced torpedoes,

    • Modern missiles and state of the art countermeasure systems.

  • This would provide a major boost to the indigenous design and construction capability of submarines in India,

    • In addition to bringing in the latest submarine design and technologies as part of the project

  • The state-of-art technology used in the submarine has ensured superior stealth features such as

    • advanced acoustic absorption techniques

    • low radiated noise levels

    • hydro- dynamically optimised shape

    • ability to attack the enemy using precision guided weapons


  • INS KALVARI- launched on 27 October 2015 and commissioned on 14 December 2017.

  • INS KHANDERI-launched on 12 Jan 2017 and commissioned on 28 Sep 2019.

  • INS KARANJ-launched on 31 January 2018 and commissioned on 10 Mar 2021.

  • INS VELA-launched on 6 May 2019

  • INS VAGIR-launched on 12 Nov 2020


  • The strategic partnership model seeks to identify a few Indian private companies as Strategic Partners (SP) who would initially tie up with a few shortlisted foreign Original Equipment Manufacturers (OEMs) to manufacture big-ticket military platforms.

  • In the initial phase, the selection of SPs would be confined to four segments:

    • Fighter Aircraft

    • Helicopters

    • Submarines

    • Armoured Fighting Vehicles (AFV)/Main Battle Tanks (MBT).

  • In each segment, “only one SP would generally be selected”.


  • The objective of the Defence Acquisition Council is to ensure expeditious procurement of the approved requirements of the Armed Forces in terms of capabilities sought, and time frame prescribed, by optimally utilizing the allocated budgetary resources.
