Russia May Build India New Super Advanced Submarine

India and Russia are in the final stages of talks for Delhi to lease another nuclear attack submarine from Moscow.
According to India’s Economic Times, Indian Prime Minister Narendra Modi and President Vladimir Putin will discuss the deal on the sidelines of the BRICS Leadership Summit currently being held in Ufa, Russia.
“Several sources related to the project that ET spoke with confirmed that talks on leasing a new submarine under the 'Chakra 3' project are in advanced stages and that the issue will be discussed during Prime Minister Modi's visit to Russia this week,” the report said.
There has been previous signs that India intends to lease a second Russian-built nuclear attack submarine (SSK). And, during a trip to India last year, Vladimir Putin indicated that Russia would be interested in such a deal.
However, the new Economic Times report said that in contrast to previous Indo-Russian submarine deals, under the “Chakra 3” project, Russia will build India a customized submarine. The report speculates that the boat may be one of Russia’s new Yasen-class submarines, or else a derivative with a similar design.   
"The final shape is yet to be decided, but it is now almost certain that a 'greenfield' submarine will be built," ET quotes an unnamed source close to the program as saying.
A Yasen-like submarine would be a significant boost to India’s depleted undersea fleet. As Kyle Mizokami has observed on The National Interest: “The Yasen class is one of the most advanced submarines in the world. The class reportedly has a crew of only ninety, implying a high level of automation. A 200MW nuclear reactor is thought to power the submarine to a maximum speed of 35 to 40 knots, with a ‘quiet operating speed’ of 20 knots.”
Regarding weaponry, Mizokami pointed out that: “The Yasen class has eight vertical launch tubes, four 650mm torpedo tubes and four standard-diameter 533mm torpedo tubes. Besides standard guided torpedoes, Yasen will almost certainly be armed with the Shkval supercavitating torpedo, capable of traveling at 200 knots to ranges from 7 to 13 kilometers.”
India is currently in the process of trying to revamp its submarine fleet, which has been battered by a number of mishaps in recent years. For starters, India is trying to build nuclear-powered ballistic missile (SSBNs) to serve as the sea-based leg of its strategic deterrence.
