The refitting of Indian navy's Kilo class diesel-electric submarine INS Sindhughosh has been completed, with Russia handing it over to the crew.
The work, which started two years ago, involved major upgradation at the 'Zvyozdochka' shipyard in Severodvinsk on the White Sea.
After successfully passing the final tests in the White Sea last week, the sub is set to sail for home port this weekend.
Earlier this month, INS Sindhughosh completed the tests of newly fitted deadly 'Club-S' cruise missiles at a firing range of the Russian Northern Fleet's Belomorskaya naval station in the White Sea, Regions.ru web portal reported.
INS Sindhughosh is the third Kilo class submarine of project 877EKM modernised by Zvyozdochka. It was built in 1985 at Soviet Admiralty Shipyard in Leningrad, now St Petersburg.
