First out of six Project 636M Improved Kilo-class diesel-electric submarines built by JSC Admiralteyskie Verfi shipyard (St. Petersburg) on Aug 28 was rolled out of the covered workshop to the launching dock and prepared for putting afloat. At request of the customer – Vietnamese Navy – the ceremony was held behind closed doors without press.
The vessel under serial number 01339 will become the first-ever submarine within Vietnamese Navy.
