Russia Floats Out ‘Stealth’ Submarine for Black Sea Fleet
ST. PETERSBURG, November 28 (RIA Novosti) – A St. Petersburg-based shipyard on Thursday floated out the first of six Varshavyanka-class diesel-electric submarines to be delivered to the Black Sea Fleet in the next two years. The much-anticipated delivery of these submarines, dubbed by the US Navy as “black holes in the ocean” because they are nearly undetectable when submerged, is a key part of Russia’s naval strategy in the Mediterranean, where Moscow has recently deployed a permanent task force consisting of some 10 surface ships.
Construction of the Novorossiisk submarine started at Admiralty Shipyards in August 2010, followed by the Rostov-on-Don sub in November 2011 and the Stary Oskol in August 2012.
The Varshavyanka-class (Project 636) is an improved version of the Kilo-class submarines and features advanced stealth technology, extended combat range and the ability to strike land, surface and underwater targets.
