Russia Launches New Stealth Sub
Russia has launched its new state-of-the-art Novorossiysk submarine, which set sail from a St Petersburg shipyard to become the first of six diesel-electric stealth subs delivered to the Russian Black Sea fleet in the next two years. The Novorossiysk belongs to the Varshavyanka-class (Project 636), which is characterized by advanced stealth technology, making it virtually undetectable when submerged. "Our potential opponents call it the 'Black Hole' due to the very low noise emission and visibility of the submarine," Konstantin Tabachny, captain of the Novorossiysk, told Channel One TV. "To be undetectable is the main quality for a submarine. And this whole project really fits its purpose." The construction of the Novorossiysk at St Petersburg's Admiralty Shipyards took over three years, beginning in August 2010. Construction was also started on two other Varshavyanka-class vessels -- the Rostov-on-Don sub in November 2011 and the Stary Oskol in August 2012. Project-636 submarines are mainly intended for anti-shipping and anti-submarine missions in relatively shallow waters. Source: http://on.rt.com/xmec8n
