Russia's missile-carrying strategic submarine K-84 Yekaterinburg (Project 6677) was taken out to sea for the first time on Friday since it underwent repair at the Zvyozdochka plant after being damaged in a fire in December 2011, a shipbuilding industry source told Interfax-AVN.
"The Yekaterinburg was taken out to sea today for a day of in-plant trials," the source said.
The vessel is expected to rejoin the Russian Navy after another two sea trials on December 20, he added.
Forces of the White Sea Flotilla are overseeing the trials, the source said.
The submarine Yekaterinburg was undergoing routine maintenance when wooden structures in the dock, located in Roslyakovo village in the Murmansk region, caught fire and the flames spread to the vessel on December 29, 2011. The submarine's reactor was immediately shut down and radiation levels in the area remained normal.
Specialists of the Zvyozdochka plant fixed the submarine's hydroacoustic system, which was damaged in the blaze.
The nuclear submarine Yekaterinburg has a water displacement of approximately 19,000 tonnes, a maximum diving depth of 400 meters and an underwater speed of 24 knots, or some 44 kilometers per hour. It is manned by a crew of 140 people and is equipped with 16 Sineva ballistic missiles.
