The first vessel of the class, tentatively named "Spasatel Petr Gruzinskiy", was reportedly laid down at Amur Shipbuilding Plant in Komsomolsk-on-Amur, Russia, already in 2010, but the construction was later suspended.

In February 2020, Amur Shipbuilding Plant was reportedly "ahead of schedule" and the vessel, now named "Kerchenskiy Proliv", would be launched in May.
