On July 27, 2012 the Zvezdochka shipyard turned the K-407 Novomoskovsk submarine of the Project 667BDRM class over to the navy. The submarine underwent what's described as a "medium overhaul" and some modernization. In particular, it will carry the most recent version of the R-29RM missile - Sineva. The submarine is expected to stay in service for ten more years.

According to the report, Novomoskovsk arrived to Zvezdochka for overhaul at the end of 2006. However, it wasn't moved to dry dock until 2008. During the overhaul, it left the dry dock in December 2010, but was returned there in May 2011. In June 2012 it went to sea for the last round of sea trials.
