Russia will deliver the two more Varshavyanka class diesel-electric submarines to Vietnam in 2014, RIA Novosti quotes a source in defense industry.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, RIA Novosti reports.Vietnam in 2009 ordered six of the Russian-made submarines -- dubbed “black holes in the ocean” by the US Navy because they are nearly undetectable when submerged, in a step seen as an effort to counterbalance China’s expanding maritime influence in the region, RIA Novosti informs.
