Yuri Dolgorukiy the lead submarine of the Project 955 class, is being prepared to return to the sea. According to an Arms-TASS report, the ship was moved out of the repair facility and transferred to a floating dock. It was moved to the dock in December 2010, apparently to fix the problems discovered during the sea trials.
At the same time, Novomoskovsk, a Project 667BDRM/Delta IV submarine, was returned to the dock. It is the last submarine of the Project 667BDRM class that was undergoing overhaul at Zvezdochka. It seemed to be completed in December 2010, but apparently more work needs to be done.
