On Friday, December 9, a tiny rocket launch of the 21631 Bujan-M task took place at the A. M. Gorky plant in Zielonodolsk, Tatarstan. It is the eleventh unit of this kind built in this shipyard under the yard number 641. During conventional baptism, it was named Naro-Fominsk by breaking a bottle of champagne overboard. Its construction is taking a long time due to the fact that the keel under it was laid almost 4 years ago on 23 February 2018.
