26/12/2012 RIA Novosti
India has asked Russia to replace the faulty parts on the leased Nerpa nuclear-powered submarine as they affect its operational readiness, the Times of India reported.
However, shortly after the start of sea trials in November 2008, an accident on board the submarine killed 20 sailors and technical due to a toxic gas leak when the automatic fire extinguishing system malfunctioned.
The Nerpa was finally handed over to India in January after prolonged and costly repairs.
The vessel is armed with four 533-mm and four 650-mm torpedo tubes, although it cannot carry nuclear weapons under the lease provisions.
