The diesel powered submarine named Hanoi is the first of six 636 Kilo-class submarines that Vietnam buys from Russia to modernise its navy, Xinhua reported Wednesday citing Vietnam's official news agency.
The submarines are being built at Admiralty Verfi Shipyards in St. Petersburg.
The submarine is able to operate at a maximum depth of 300 metres and at a range of 6,000-7, 500 nautical miles for 45 days and nights with 52 crew members. It is the best choice for reconnaissance and patrol.
By January 3, all the attached equipment of the submarine will be unloaded before it is released into the sea.
