The K-407 Novomoskovsk submarine of the Project 667BDRM class was seen going to sea on June 1st, 2012. The submarine entered the Zvezdochka shipyard for overhaul in November 2008 (it's been in and out of the dry dock a couple of times). It is expected to return to service later this year.

Two Project 667BDRM submarines - K-51 Verkhoturie and K-84 Ekaterinburg - remain in overhaul. Verkhoturie is expected to return to service in 2012.
