Russian Akula-class Submarine Nerpa

The Russian Akula-class submarine K-152 Nerpa was launched in October 2008 and entered service with the Russian Navy in late 2009. In 2011 the submarine was leased to the Indian Navy and was formally commissioned into service as the INS Chakra II in 2012.

Akula-class nuclear-powered attack submarines are considered to be some of the quietest in the world, due to the use of the latest technology in their construction. They are capable of dealing with both underwater and surface targets and can be equipped with torpedoes and mines, as well as with long-range missiles.
