The Indian Navy had planned to build six nuclear attack submarines along with the Arihant Class SSBNs which are nuclear-powered submarines equipped with nuclear missiles.
The nuclear attack submarines are also planned to be built indigenously in partnership with private sector industries.
At present, the Navy is operating Russian-origin Kilo Class, German-origin HDW class and the latest French Scorpene-class submarines in the conventional domain while in the nuclear section, it has leased one INS Chakra (Akula class) from Russia.
The Navy also informed the committee that in the last 15 years, only two new conventional submarines have been inducted including the Scorpene-class vessels INS Kalvari and the INS Khanderi.
“It was further informed that the existing 13 conventional submarines are between 17 to 31 years old,” the standing committee report said.
The Navy is also working on a plan to build six new submarines under its Project 75 India in which six more conventional submarines would be built by the Navy in partnership with Indian companies and foreign origin equipment manufacturers. The project would be undertaken under the strategic partnership policy.
