January 22, 2021 (Google Translation) – The shipbuilders of the Sredne-Nevsky shipbuilding plant (part of the United Shipbuilding Corporation) brought the mine defense ship (PMO) “Pyotr Ilyichev” of project 12700 “Alexandrite” out of the workshop.
By the end of 2020, the shipyard specialists completed work on the formation of the hull and part of the superstructure of the ship, their saturation with systems and mechanisms. Further outfitting work will be carried out outside the workshop. The plant workers will have to install the second tier of the minesweeper superstructure, install the tower-mast device, antenna equipment and general ship systems. The launch of the ship is scheduled for February 2021.
The ship PMO “Pyotr Ilyichev” was laid down in July 2018. She became the sixth ship in the Project 12700 Alexandrite line, which the Sredne-Nevsky shipyard is building by order of the Russian Navy. Previously, the plant handed over to the customer four ships of this project. Four more (including the ship PMO “Pyotr Ilyichev”) are at the shipyard in varying degrees of readiness.
Project 12700 Alexandrite was developed by the Almaz Central Marine Design Bureau (part of the United Shipbuilding Corporation). These ships belong to a new generation of mine-sweeping forces and are designed to combat sea mines, which the new PMO ships can detect both in the water of sea areas and in sea soil without entering the danger zone. To combat mines, ships can use various types of trawls, as well as remote-controlled and autonomous unmanned underwater vehicles.
During the construction of these ships at the Sredne-Nevsky Shipyard, the latest Russian technologies are used, which have no analogues in the world shipbuilding. The ships of this project have a unique, largest in the world hull made of monolithic fiberglass, formed by the method of vacuum infusion. Compared to metal, the weight of the composite body is 20 percent lower. It has high strength, is not susceptible to aggressive chemical environments and corrosion, and the service life, subject to operating standards, is unlimited. Other advantages of the composite hull include its “non-magnetic”, which ensures greater survivability of the ship when searching for mines.
According to the plans of the Main Command of the Russian Navy, the ships of the new generation of PMO in the short term will form the basis of the mine-sweeping forces of the fleets of the Russian Navy, significantly increasing the efficiency of mission performance.
