On November 22, 2008 the Zvezdochka shipyard in Severodvinsk launched the K-18 Karelia submarine of the Project 667BDRM class, which has been in overhaul since 2004. The overhaul is reported to be "71 percent complete" and the submarine is expected to return to service in late 2009.

Karelia will join four submarines of the Project 667BDRM class that have completed overhaul already - K-51 Verkhoturie, K-84 Ekaterinburg, K-114 Tula, and K-117 Bryansk. The next submarine in line for an overhaul is K-407 Novomoskovsk.

As part of the overhaul and modernization process Karelia will carry a version of the R-29RM missile known as Sineva. It appears that it will be the third submarine equipped with Sineva missiles - after K-114 Tula, which returned to service in January 2006, and K-117 Bryansk, which returned in January 2008.

P.S. Here is an interesting bit of data reported in one of the news stories - during its 15 years in service Karelia conducted 38 patrols and traveled 140 thousand miles, which indicates that it did not normally stray very far from its base.
