The well-equipped Kilo 636 was built at Admiralty Verfi shipyard in St Petersburg and given a trial run in July.
It will set sail and head for a Vietnamese port in mid November, RIA Novosti reported, adding the second vessel is being given a test run at the Baltic Sea.
Vietnam is scheduled to receive the first two submarines in 2013 and the last in 2016.
