India is determined to make sure that the production of Six next-generation submarines comes with the highest indigenous content that will be a perfect road-map for the development of Project-76 the successor program which Indian Navy Bureau will be in charge of the design and development of indigenous conventional submarine post-Project-75 I.
Four contenders in the Project-75I have been recently notified that winning bidder will have to use local, DMR 249A steel plates developed by the State-run Steel Authority of India (SAIL), which will negate import of military grade steel from abroad, and also will come handy in the development of future local submarines.
The Second most important factor which has been notified is that weapons system to be used for the Project-75I will have Varunastra advanced heavyweight anti-submarine torpedo along with Submarine Launched Cruise Missile (SLCM) like BrahMos and Nirbhay which will practically make India free of its dependency on foreign weapons manufactures.
DRDO developed Air-independent propulsion (AIP) will not only make its way into current Kalvari-class submarines, but will also be installed on Project-75I which is another step towards localization of the submarine. Indian Navy also wants to keep export rights of the submarine with due royalties to the OEM, if Indian shipyards are able to bag export orders for the submarines which can take orders beyond Six mandated by the Indian Navy.
Indian Navy will be in charge of Project-76, which will be the development of 6 to 12 next-generation conventional submarines which will be executed by Public and Private sector shipyard in India post-2030. The Indian Naval Bureau is presently undertaken design and development work for Six Nuclear Attack Class Submarines, along with bigger ballistic missile submarine which will be the successor to the current Arihant class Nuclear ballistic missile submarines.
