Heavy lift vessel Rolldock Sea , carrying the submarine, arrived at Cam Ranh port on January 1 after a six-week voyage from St Petersburg.
The submarine is scheduled to be handed over to the Vietnamese side on January 10.
The nation’s second submarine, to be named Ho Chi Minh, is expected to arrive in Cam Ranh Bay next March.
The Hanoi is the first of the six diesel-powered 636 Varshavyanka (kilo)-class submarines that Vietnam has purchased from Russia in an effort to modernise its navy, enhancing the capacity to defend the country’s territorial waters.
The other submarines are under construction 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.
