K-152 Nerpa is a Project 971I Schuka-B nuclear-powered attack submarine.

REGISTRATION

The submarine passes trials

CONSTRUCTION, NAME

The sub was launched in 1993 under Project 971 at Amur Shipyard. In 2002 the works were frozen due to lack of financing so the sub was launched only in June 4, 2006. In 2004 fitting-out of the sub started under Project 971I to lease her for India.

MILESTONES

As a consequence of freon release happened in Nerpa on Nov 8, 2008 during its sea trials in the Sea of Japan, 20 died and 21 were intoxicated out of 208 attendants. Seaman Dmitry Grobov was accused in "causing death carelessly to two or more persons" as per part 3 clause 109 of the RF Criminal Code which provides deprivation of freedom on term up to five years. Supposedly, the seaman incorrectly adjusted an air temperature sensor in living compartment and that led to emergency actuation of firefighting system.

Recovery works cost RUR 1.9 bln, because some equipment suffered from carbon dichloride which is a strong solvent. The counterfeit fire suppressant was replaced with the standard one. Control procedure of the fire-smothering system was changed as well. All equipment was inspected, and the 200-men trial team passed retraining course.

On January 23, 2012, the submarine was leased to India after a five-year delay. In Indian Navy, the submarine was renamed into INS Chakra. Solemn commissioning ceremony took place in Vishakhapatnam on April 4, 2012.
