Russia’s Nerpa nuclear submarine has finished sea trials and is now ready to be leased to the Indian navy in the next few days, an engineer said on Wednesday. \"The submarine is now fully ready to carry out its tasks,\" a senior executive at the Amur Shipyard, where the submarine was built, told Russian RIA Novosti news agency . \"It will be handed over before the end of the year.\" When Russia makes the delivery, it will make India only the sixth operator of nuclear submarines in the world. Earlier this month, it launched the first of its own nuclear submarines. The ten-year lease is worth $920 milion. The Nerpa, an Akula II-class attack submarine, had originally been scheduled for delivery in 2008 but an accident earlier that year forced the Russian authorities to put it on hold. Twenty people, mostly civilians, were killed when a fire-suppressant gas was released on the Nerpa during shakedown trials, in one of Russia’s worst naval accidents. Meanwhile Deputy Prime Minister Sergei Ivanov said today that .Russia and India are highly likely to sign a fifth-generation fighter design contract in December. Russia\'\'s Sukhoi holding and India\'\'s Hindustan Aeronautics Limited (HAL) agreed in early 2010 to jointly develop a fifth-generation fighter jet. India confirmed that it had finalized a draft contract at a meeting with Russia in early October. \"If all procedures are completed by the time of our president\'\'s visit [to India] in December, the contract will be ready for signing,\" Ivanov said. The new aircraft will be based on Russia\'\'s T-50 prototype fifth-generation fighter, which has already made several test flights, and is expected to enter service with the Russian Air Force in 2015.(QNA) MD
