New Delhi: As part of the exercise to boost maritime strength, Indian Navy has plans on the anvil to a total of 24 submarines including six nuclear attack submarines, a Parliamentary Committee report said.

“Eighteen (Conventional) plus six SSN (nuclear-powered attack) submarines are planned but the existing strength is 15 and one SSN is available on lease,” the Standing Committee on Defence said in its report tabled in the Winter Session of Parliament.

The 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 boats in the conventional domain while in the nuclear section, it has leased one INS Chakra (Akula class) from Russia.

Indian 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 INS Khanderi.

“The existing 13 conventional submarines are between 17 to 31 years old,” the standing committee report added.
