History

The first two Project 23131 ships, serial numbers "301" and "302", were laid down during a keel laying ceremony at the Zaliv shipyard, Kerch on 26 December 2014, planned to enter service in 2018.^[1][2] However, in February 2015, it was reported that construction of the two tankers had been halted, and that the sections that had been laid down in 2014 had been subsequently cut into scrap metal.^[3][4] In November 2018, Zaliv shipyard reported that the formation of the ships' hulls and superstructures was complete and that work was currently underway to prepare the two hulls for electrical installations.^[5]
