BS-64 Подмосковье (Podmoskovye = ‘Moscow Oblast’) is a Project 09787 DELTA-IV STRETCH ballistic missile submarine which has been converted into a host submarine for nuclear powered midget-subs. She was relaunched on October 22nd and is expected to join 29th Separate Brigade of submarines of the Northern Fleet at their secretive base at Olenya Guba (Deer Bay) on the Murmansk Oblast. The 29th Separate Brigade operate a range of Special Mission submarines (read ‘Spy submarines’) for GUGI (Main Directorate Deep Sea Research). Podmoskovye will be used as a Host Submarine (‘mother submarine’) for some of the midget submarines based there, most likely including the elusive Project 10831 LOSHARIK. On 1st July 2019 a serious accident occured aboard Losharik as she docked with BS-64 resulting in the death of 14 hydronauts aboard the midget submarine.

At the center of the cradle there is an access trunk for crew access to the payload, which in this case is probably a Project 18270 BESTER rescue submersible (DSRV – Deep Sea Rescue Vehicle). Photo of a BESTER aboard rescue ship Igor Belousov, note the access hatch at the bottom which mates with the hatch on the ship, per the one on the submarine’s cradle:
