Heavy lift vessel Rolldock Sea , carrying the first Kilo submarine Russia is building for Vietnam , arrived at the Cam Ranh port in central Khanh Hoa province, after a one-and-a half month voyage from St Petersburg .

By January 3, all the attached equipment of the submarine will be unloaded before it is released into the sea.

The Kilo-636 submarine, named Hanoi , is the first of the six 636 Varshavyanka (kilo)-class submarines run by diesel power that Vietnam buys from Russia to modernise its navy, enhancing the capacity to defend the country’s territorial waters. The submarines are being built at Admiralty Verfi Shipyards in St. Petersburg .

Having a displacement of 3,000-3,950 tonnes, the 73.8m long submarine can 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 crewmembers. It has the quietest engine in the world and is the best choice for reconnaissance and patrols.-VNA
