BS-64 is a Project 667BDRM Delfin-class ballistic missile submarine (NATO reporting name "Delta-IV") of the Russian Navy. She was originally designated K-64.
K-64 was removed from active service in 1999 and was ordered to be refitted. It was planned for her to be reactivated in 2002 to replace the Yankee 'Stretch' class KS-411. KS-411 had been the mothership for the Paltus-class mini submarines, which are believed to be used for a combination of oceanographic research, search and rescue, and underwater intelligence-gathering. Due to lack of funds was this plan postponed. K-64 was renamed BS-64 in 2002, and her central section containing 16 silos for ballistic missiles was removed to create space for the installation of scientific-experimental equipment, cabins for scientists and a rest room for the regular crew. As of 2008 the ship was still moored in Zvezdochka shipyard awaiting completion.
The submarine was relaunched after repairs in August 2015. Following the completion of repairs it is believed that the submarine was converted to serve as carrier of mini submarine(s) (e.g., "Losharik" deep-diving nuclear powered mini-submarine). Sea trials started in the White Sea in October 2016 and the submarine was handed over to the Russian Navy in December the same year as a Pr. 09787 carrier of mini-submarines and possibly as a deep-water nuclear station.
The Losharik (Pr. 1983.1). Launched in 2003 and operational since 2007, this craft of 60 meters (74 according to some sources) is, according to information available, armed with a crew of 25 sailors and designed to operate quietly, although being able if necessary to escape at high speed (referred to 40 knots). It has as the Paltus a titanium shell, allowing to deep immersion.
