India’s quest to operate a  nuclear submarine for its strategic  needs has met with yet another  hurdle. The much-awaited Akula-II class,  8,140 tonne Nerpa attack  submarine from Russia, will not meet its  year-end schedule of delivery  to the Indian Navy. 
Sources   said the Navy, as of now, has refused to accept the submarine from its   Russian counterparts citing inadequate training for its teams to  operate  the vessel. The submarine is to be leased by Russia for 10  years under a  $650-million pact signed in January 2004. 
 
 
The   Indian naval teams do not have enough under-sea operating experience  on  board the nuclear-powered Nerpa, hence the Russians have been told  to  provide more hours of training, sources confirmed to The Tribune.  The  training of the Navy teams has been going on for the past one year  but  the top brass is “not satisfied” with the operational ability that  has  been acquired so far. This training will take some five months to   complete, which means a new delivery deadline of March 2011 has been   fixed. 
This is the  third  such shift in the deadline for the delivery of the vessel. The  Nerpa was  initially slated for lease to India in mid-2008. An accident  on board  the undertrial submarine in the Sea of Japan killed 20 Russian  sailors.  After a $65 million re-fit later, the delivery was  rescheduled for June  this year. The Indo-Russian group on military  technical cooperation met  in July this year. The Russians promised that  the submarine would be  handed over to India by the end of this year. 
The   operation of a nuclear submarine is different from a conventional   submarine. Indian Navy last operated one some 19 years ago in 1991.   Since, the officers who operated it have long retired taking with them   the “institutional memory”. Since 1991, the ability of Russia, carved   out of the erstwhile USSR, diminished to build world class vessels for   itself. India did not have tie-ups with other countries. The one with   France to build six diesel-electric powered submarines, the scorpene,   was signed only a few years ago. 
The   Nerpa is vital as it will bridge the operational gap between now and   the commissioning of the indigenously built nuclear-sub, the INS   Arihant, which will join the fleet in 2012. The Arihant will have two   more follow-on nuclear-subs and the three in total will cost India Rs   33,000 crore. 
Technically,  the Nerpa at  110-metre length is considered the quietest and deadliest  of all Russian  nuclear-powered submarines. The Amur Shipyard located  in the Russian  far-east has further reduced its acoustic noises. Unlike  its  diesel-electric powered cousins, the Nerpa, being N-powered, does  not  have to surface to “breathe”. It can remain under water for 100  days  while conventional subs surface every few days to take in air.
