Indian Navy is all set to operate five nuclear submarines by the end of this decade, including two leased from Russia and three built indigenously. Defence Minister A K Antony said, India is considering a proposal to induct another nuclear submarine built in Russia and has plans of indigenously building two more Arihant Class underwater vessels to guard its maritime boundaries.

The Navy on Wednesday formally commissioned the Akula-II Class INS Chakra in Vishakhapatnam and is set to launch the INS Arihant for sea trials soon.

On India's plans to expand its nuclear submarine fleet Antony said the government was considering a proposal in this regard and the country can afford to buy another such vessel.

AIR correspondent reports, the Navy which currently operates more than 10 conventional diesel-electric submarines of the Kilo and HDW Class, has plans of inducting a dozen more in the next decade.

Already six Scorpene submarines are being constructed at Mazagon Dockyards in Mumbai in collaboration with French DCNS and six more are planned to be built under the Project-75 India.
