Russia and India completed transfer of a nuclear attack submarine to the Indian Navy. The K-152 Nerpa submarine of the Project 971/Akula II class was handed over to the Indian crew in December 2011. It reportedly left the shipbuilding plant in Primorsky Kray in the Far east at the end of February 2012 and is expected to arrive to its base at Visakhapatnam in the Bay of Bengal on March 30-31, 2012.

The submarine has been leased to India for 10 years. The cost of the contract is estimated to be about $950 million. The submarine is powered by a single nuclear reactor of the OK-650V type. Reactors of this type are believed to be using fuel with uranium enriched to 21% and 45%.
